Several discovered fossils illustrated deliberate attacks on Mosasaurus individuals by members of the same species.

Infighting likely took place in the form of snout grappling, similarly seen in modern crocodiles today. The first remains of Mosasaurus known to science are fragments of a skull discovered in at a subterranean chalk quarry under Mount Saint Peter , a hill near Maastricht , the Netherlands.

In , van Marum published a description of the fossil, considering it to be a species of "big breathing fish" in other words, a whale under the classification Pisces cetacei.

Around , [a] a second more complete skull was discovered at the same quarry. A retired Dutch army physician named Johann Leonard Hoffmann took a keen interest in this specimen, who corresponded with the famous biologist Petrus Camper regarding its identification.

Hoffmann, who had previously collected various mosasaur bones in , presumed that the animal was a crocodile. As a result, the second skull gained international fame.

Godding was struck by its beauty and took every measure to conserve it, eventually displaying it inside a grotto behind his house. By the time it arrived at the museum, various parts of the skull were lost.

However, the fate of these bones is unknown, and some historians believe that Rosa mentioned them in hopes of negotiating indemnity.

The French government refused to return the fossil but recompensed Godding in by exempting him from war taxes.

According to Faujas, Hoffmann was the original owner of the specimen, which he purchased from the quarrymen and helped excavate.

When the news of this discovery reached Godding, whom Faujas painted as a malevolent figure, he sought to take possession of the greatly valuable specimen for himself and filed a lawsuit against Hoffmann, claiming his rights as landowner.

Due to Godding's position as a canon, he influenced the courts and was able to force Hoffmann to relinquish the fossil and pay for the costs of the lawsuit.

When Maastricht was attacked by the French, the artillerymen were aware that the famous fossil was stored at Godding's house.

Godding did not know his house was spared and he hid the specimen in a secret location in town. Historians have found little evidence to back up Faujas' account.

For example, there is no evidence that Hoffmann ever possessed the fossil, that a lawsuit involved him and Godding, or that Faujas was directly involved in acquiring the fossil.

More reliable but contradictory accounts suggests that his narrative was mostly made up: Faujas was known to be a notorious liar who commonly embellished his stories, and it is likely that he falsified the story to disguise evidence of looting from a private owner which was a war crime , to make French propaganda, or to simply impress others.

Nevertheless, the legend created by Faujas' embellishment has helped elevate the second skull into one of cultural fame.

Unlike its renowned contemporary, the first skull TM was not seized by the French after the capture of Maastricht. During Faujas and his three colleagues' mission in , the collections of Teylers Museum, despite being famous, were protected from confiscation.

It is possible that the four men were instructed to protect all private collections as "inviolable" unless its owner was declared a rebel, and were prohibited from seizing the Teylers Museum's collections.

Before the second skull was seized by the French in late , the two most popular hypotheses regarding its identification were that it represented the remains of either a crocodile or whale, as first argued by Hoffmann and Camper respectively.

Hoffmann's identification as a crocodile was viewed by many at the time to be the most obvious answer; there were no widespread ideas of evolution and extinction at the time, and the skull superficially resembled a crocodile.

First, Camper noted that the skull's jawbones had a smooth texture and its teeth were solid at the root, similar to those in sperm whales and dissimilar to the crocodile's porous jawbones and hollow teeth.

Second, Camper obtained mosasaur phalanges which he noted to be significantly different from those of crocodiles and instead suggested paddle-shaped limbs, which were another cetacean feature.

Third, Camper noted the presence of teeth in the pterygoid bone of the skull, which he observed are not present in crocodiles but are present in many species of fish Camper also thought that the rudimentary teeth of the sperm whale, which he erroneously believed was a species of fish, corresponded to pterygoid teeth.

Lastly, Camper pointed out that all other fossils from Maastricht are marine, which indicates that the animal represented by the skull must have been a marine animal.

Because he erroneously believed that crocodiles are entirely freshwater animals, Camper concluded by process of elimination that the animal could only be a whale.

Originally intending to defend his father's arguments, Camper Jr. He concluded that the animal must have been a large marine lizard with varanoid affinities.

In , Camper Jr. Prior to this, almost all fossils, when recognized as having come from once-living life forms, were interpreted as forms similar to those of the modern day.

Cuvier's idea of the Maastricht specimen being a gigantic version of a modern animal unlike any species alive today seemed strange, even to him. Even though the binomial naming system was well established at the time, Cuvier never designated a scientific name to the new species and for a while, it continued being referred to as the "great animal of Maastricht".

In , English doctor James Parkinson published a conversation that included a suggestion made by Llandaff dean William Daniel Conybeare to refer to the species as the Mosasaurus as a temporary name until Cuvier decided on a permanent scientific name.

In , English paleontologist Gideon Mantell added the specific epithet hoffmannii in in honor of Hoffmann.

The first possible recorded discovery of a mosasaur in North America was of a partial skeleton described as "a fish" in by Meriwether Lewis and William Clark 's Corps of Discovery during their — expedition across the western United States.

Four members of the expedition recorded the discovery in their journals including Clark and Gass. The earliest description of North American fossils firmly attributed to the genus Mosasaurus was made in by naturalist Samuel L.

Mitchill of the Lyceum of Natural History. The described fossils were of a tooth and jaw fragment recovered from a marl pit from Monmouth County, New Jersey , which Mitchell described as "a lizard monster or saurian animal resembling the famous fossil reptile of Maestricht", implying that the fossils had affinities with the then-unnamed M.

Cuvier was aware of this discovery but doubted whether it belonged to the genus Mosasaurus. Additionally, another foreign naturalist "unreservedly" declared that the fossils instead belonged to a species of Ichthyosaurus.

The type specimen of the second species M. This specimen, which consisted of some vertebrae and a partially complete articulated skull notably missing the end of its snout, was brought back to St.

Louis , where it was purchased by an Indian agent as home decoration. This fossil caught the attention of German prince Maximilian of Weid-Neuwied during his — travels in the American West.

He purchased the fossil and subsequently sent it to naturalist Georg August Goldfuss of the University of Bonn for research. Goldfuss carefully prepared and described the specimen, which he concluded was of a new species of Mosasaurus and in named it M.

Harlan thought it belonged to a species of Ichthyosaurus based on perceived similarities with the skeletons from England in features of the teeth and positioning of the nostrils and named it Ichthyosaurus missouriensis.

This could not be confirmed at the time because the fossil snout was lost. In , it was rediscovered inside the collections of the National Museum of Natural History, France under the catalog number MNHN ; examination of the specimen's information revealed that Harlan at one point donated the fossil to the museum, where it was promptly forgotten until its rediscovery.

The snout matched perfectly into the Goldfuss skull, confirming that it was the specimen's missing snout. Because of its earlier description, Harlan's taxon took priority, making the final scientific name M.

Scientists have initially imagined that Mosasaurus had webbed feet and terrestrial limbs and thus was an amphibious marine reptile capable of both terrestrial and aquatic locomotion.

Scholars like Goldfuss argued that the skeletal features of Mosasaurus known at the time such as an elastic vertebral column indicated a walking ability; if Mosasaurus was entirely aquatic, it would have been better supported by a stiff backbone.

But in , German zoologist Hermann Schlegel became the first to prove through anatomical evidence that Mosasaurus had flippers instead of feet.

Using fossils of Mosasaurus phalanges including the gypsum-encased specimens collected by Hoffmann which Schlegel extracted from the gypsum, noting that it may have misled previous scientists , he observed that they were broad and flat and showed no indication of muscle or tendon attachment, indicating that Mosasaurus was incapable of walking and instead had flipper-like limbs for a fully aquatic lifestyle.

Schlegel's hypothesis was largely ignored by his contemporaries, but was more widely accepted in the s when more complete mosasaur fossils in North America were discovered by American paleontologists Othniel Charles Marsh and Edward Drinker Cope.

One of the earliest paleoart depictions of Mosasaurus is a life-size concrete sculpture constructed by natural history sculptor Benjamin Waterhouse Hawkins between and as part of the collection of sculptures of prehistoric animals on display at the Crystal Palace in London , the former house of the Great Exhibition.

Hawkins sculpted the model under the direction of the English paleontologist Sir Richard Owen , who was informed on the possible appearance of Mosasaurus primarily based on the holotype skull.

Given the knowledge of the possible relationships between Mosasaurus and monitor lizards, Hawkins depicted the prehistoric animal as essentially a water-going monitor lizard.

The head was large and boxy, which was informed by Owen's estimations of the holotype skull's dimensions being 2.

The skin was given a robust scaley texture similar to those found in larger monitor lizards such as the komodo dragon. Depicted limbs include a right single flipper, which reflected on the aquatic nature of Mosasaurus.

However, the model was uniquely sculpted deliberately incomplete, with only the head, back, and single flipper having been constructed.

This has been commonly attributed to Owen's lack of clear knowledge regarding the postcranial anatomy of Mosasaurus , but paleontologist and paleoartist Mark P.

Witton found this unlikely given that Owen was able to guide a full speculative reconstruction of a Dicynodon sculpture which was also known solely from skulls at the time.

Witton instead suggested that time and financial constraints may have influenced Hawkins to cut corners and sculpt the Mosasaurus model in a way that would be incomplete but visually acceptable.

The depiction of Mosasaurus with a boxy head, side-positioned nose, and flippers contradicted the studies of Goldfuss , whose examinations of the vertebrae and near-complete and undistorted skull of M.

The ignorance of these findings may have been due to a general ignorance of Goldfuss's studies by other contemporaneous scientists.

Confirmed species other than M. Case reexamined the holotype fossils and found that the species belonged under Mosasaurus instead and renamed it Mosasaurus conodon.

The fourth species M. The skull was one of many fossils donated to the Royal Belgian Institute of Natural Sciences by Alfred Lemonnier, the director of the quarry; as such, Dollo named the species in his honor.

These fossils include multiple partial skeletons, which were enough to almost represent the entire skeleton of M.

All known fossils of the species reside in the collections of the same museum; the holotype skull is cataloged as IRSNB R Paleontologist Theagarten Lingham-Soliar of Nelson Mandela University suggested two reasons for such neglect: the first reason was that M.

The second reason was that M. However, he declared that better studies of M. However, there are still some differences such as the exclusive presence of fluting in M.

The fifth species, M. In a study, paleontologists led by Nathalie Bardet of the same museum reexamined Arambourg's teeth and found that only three can be firmly attributed to M.

Two of the other teeth were described as having variations that may possibly be within the species but were ultimately not referred to M.

The study also described more complete M. The type species of Mosasaurus is one of the largest mosasaurs known. As the species is well-represented by fossil skulls, the length of the skull or lower jaw can be extrapolated to a hypothetical ratio between it and the total length.

The study estimated that an M. Isolated bones suggest that some M. It was not stated whether the ratio from Russell was applied. Based on measurements of various Belgian skeletons, Dollo estimated that M.

The skull of Mosasaurus is conical and tapers off to a short and conical rostrum that extends a little beyond the premaxillary teeth. Above the gum line in both jaws, a single-file pattern of small pits known as foramina are lined parallel to the jawline; they are used to hold the terminal branches of jaw nerves.

A number of foramina are also present along the rostrum in a pattern similar to that found in skulls of Clidastes.

They are positioned more posteriorly than any other mosasaur and begin above the fourth or fifth maxillary teeth; posterior positioning is only exceeded in Goronyosaurus.

The palatal complex, which consists of the pterygoid bones, palatine bone , and nearby bones of other processes, was tightly packed to provide greater cranial stability.

The neurocranium provided a brain that was narrow and relatively small compared to other mosasaurs. In contrast, the braincase of the mosasaur Plioplatecarpus marshi provided for a brain around twice the size of that in M.

Spaces within the braincase providing for the occipital lobe and cerebral hemisphere are narrow and shallow, suggesting that such brain parts were relatively small.

The parietal foramen in Mosasaurus , which is associated with the parietal eye , is the smallest in the Mosasauridae family.

The features of teeth in Mosasaurus vary across species, but characteristics that unify the genus include highly prismatic surfaces prism-shaped enamel circumference , two opposite cutting edges, and a design specialized for cutting prey.

Like all mosasaurs, Mosasaurus had four types of teeth which were named after the jaw bones they were located on. On the upper jaw, there were three types and were the premaxillary teeth, maxillary teeth , and pterygoid teeth.

On the lower jaw, only one type, the dentary teeth , were present. In each jaw row, from front to back, Mosasaurus had: two premaxillary teeth, twelve to sixteen maxillary teeth, and eight to sixteen pterygoid teeth on the upper jaw and fourteen to seventeen dentary teeth on the lower jaw.

Mosasaurus possessed a thecodont dentition , meaning that the roots of its teeth were deeply cemented within the jaw bone.

Mosasaurus did not utilize permanent teeth and constantly shed them. Replacement teeth develop within the roots of the original tooth inside a resorption pit through an eight-stage process that is autapomorphic , or distinctly unique, to mosasaurs.

The first stage is characterized by the mineralization of a small tooth crown developed elsewhere that descends into the resorption pit by the second stage.

In the third stage, the developing crown firmly cements itself within the resorption pit and grows in size; by the fourth stage, it is of the same size as the crown in the original tooth.

Stages five and six are characterized by the development of the replacement tooth's root: in stage five the root develops vertically, and in stage six the root expands in all directions, to the point that the replacement tooth becomes exposed and actively pushes on the original tooth.

In the seventh stage, the original tooth is shed and the now-independent replacement tooth begins to anchor itself into the vacancy. In the eighth and final stage, the replacement tooth has grown to firmly anchor itself.

The most complete skeleton of Mosasaurus , whose species-level identification is debated [11] [7] and is on display at the Museum of Geology at the South Dakota School of Mines and Technology under the catalog SDSM , has seven cervical vertebrae in the neck, thirty-eight dorsal vertebrae which includes thoracic and lumbar vertebrae in the back, and eight pygal vertebrae front tail vertebrae lacking chevrons followed by sixty-eight caudal vertebrae in the tail.

All species of Mosasaurus have seven cervical vertebrae, but other vertebral counts vary among them. Various partial skeletons of M. Extensive cartilage likely connected the ribs with the sternum , which would have facilitated breathing movements and compression when in deeper waters.

The tail is bilobed and hypocercal , which means that the tail vertebrae extends toward the lower lobe. The centra [i] of the tail vertebrae gradually shorten around the center of the tail and lengthen behind the center, suggesting rigidness around the tail center and excellent flexibility posterior to it.

Like most advanced mosasaurs, the tail bends slightly downwards as it approached the center, but this bend is at a small degree with little offset from the body.

Mosasaurus also has large haemal arches in the caudal vertebrae that bend near the middle of the tail, which contrasts with the reduction of haemal arches in other marine reptiles such as ichthyosaurs.

These and other features support a large and powerful paddle-like fluke in Mosasaurus. The forelimbs of Mosasaurus are wide and robust.

The radius and ulna are short, but the former is taller and larger than the latter. The overall structure of the paddle is compressed, similar to that in Plotosaurus , and is well-suited for utilization for faster swimming.

The ilium is rod-like and slender; in M. Because the rules of nomenclature were not well defined at the time, 19th century scientists did not give Mosasaurus a proper diagnosis during its first descriptions.

This led to ambiguity regarding the definition of the genus, which led it to become a wastebasket taxon that contained as many as fifty different species.

The taxonomic issue was so severe that there were cases of species that were found to be junior synonyms of species that were found to be junior synonyms themselves For example, four taxa became junior synonyms of M.

This issue was recognized by many scientists at the time, but efforts to clean up the taxonomy of Mosasaurus were hindered due to a lack of a clear diagnosis.

In , Russell published Systematics and Morphology of American Mosasaurs , which contained one of the earliest proper diagnoses of Mosasaurus.

Although his work is considered incomplete as he worked solely on North American representatives and did not examine European representatives such as M.

He identified eight species that he considered valid— M. During the late 20th century, scientists described four additional species from fossils found in the Pacific— M.

In , the doctoral thesis of paleontologist Halle Street of the University of Alberta was published. This thesis, supervised by paleontologist Michael Caldwell, performed the first proper description and diagnosis of M.

A phylogenetic study was performed in the thesis, which tested the relationships between M. Of the twelve candidate species, only M. The placement of M.

Representatives of M. It was named M. Street stated in her thesis that its contents are intended to be published as scientific papers.

The diagnosis of the Mosasaurus holotype was published in a peer-reviewed paper co-authored with Caldwell. Mosasaurus is a member of the order Squamata which comprises of lizards and snakes and the type genus of the family Mosasauridae and subfamily Mosasaurinae.

The genus also belongs to a tribe traditionally shared with the mosasaur genera Eremiasaurus , Plotosaurus , [61] and Moanasaurus , [k] [60] but the naming of this tribe is controversial.

It was originally erected by Russell under the name Mosasaurini. Russell's description of the tribe was based on the belief that Plotosaurus was not closely related to Mosasaurus , which was classified into a separate tribe called the Plotosaurini.

In a study, paleontologist Gorden Bell recovered Plotosaurus as a sister genus to Mosasaurus. This rendered the Mosasaurini tribe paraphyletic , which meant that it now contains a descendant lineage Plotosaurini that is not classified under it.

While other scientists agree that a tribe containing Mosasaurus should be monophyletic , they argue that Mosasaurini should be the valid tribe. For example, in a study, Aaron LeBlanc, Caldwell, and Bardet argued that, while it is not necessarily invalid, abandoning Mosasaurini would not follow the general principle of the type genus carrying over to all ranks in a classification hierarchy, and that the original diagnostics of the Plotosaurini is outdated.

The specific placement of mosasaurs within the Squamata, and thus the relationship of Mosasaurus with modern reptiles, has been controversial since its inception.

Cuvier was the first scientist to deeply analyze the possible taxonomic placement of Mosasaurus. While his original hypothesis that the genus was a lizard with affinities to monitor lizards remained the most popular, Cuvier was uncertain, even at the time, about the accuracy of this placement.

He simultaneously proposed a number of alternative hypotheses, with one such alternative suggesting that Mosasaurus instead had closer affinities with iguanas due to their shared presence of pterygoid teeth.

With the absence of sufficient fossil evidence, researchers during the early and midth century had little to work with.

Instead, they primarily relied on stratigraphic associations and Cuvier's research on the holotype skull. Thus, in-depth research on the placement of Mosasaurus was not undertaken until the discovery of more complete mosasaur fossils during the late 19th century, which reignited research on the placement of mosasaurs as squamates.

In a span of about 30 to 40 years, paleontologists fiercely debated the issue, which created two major schools of thought: one that supported a monitor lizard relationship and one that supported a closer relationship with snakes.

Some scientists went as far as to interpret mosasaurs as direct ancestors of snakes. One of these was the Mosasauria, a loosely-defined group erected by Marsh in but is still used by some researchers today that generally includes all descendants of the last common ancestor of Mosasaurus and some of its ancestral relatives, including the dolichosaurs Dolichosaurus and Coniasaurus and the marine squamate Adriosaurus.

However, many studies continued to support placing mosasaurs within the Varanoidea. The debate was reignited with the publication of a cladistical study by paleontologist Michael S.

Lee of the University of Sydney , which recovered the Mosasauroidea as a sister taxon to the snake suborder Serpentes and resurrected the argument for a snake relationship.

Lee observed to be part of the reason for the trend of consistently classifying mosasaurs as varanoid lizards. Lee also resurrected the Pythonomorpha which had long gone out of use and redefined it to unify the Mosasauroidea and Serpentes under one clade.

In some of these studies, the Mosasauria clade was used to represent mosasaurs. For example, a large-scale phylogenetic study by paleontologist Jack Conrad of the American Museum of Natural History recovered the Mosasauria clade in a polytomy , or unresolved sister relationships, with monitor lizards and beaded lizards ; [66] and a study led by Jacques Gauthier of Yale University recovered Mosasauria as a clade basal to both monitor lizards and snakes.

During the s, with the advent of the field of molecular genetics , some scientists argued that combining molecular data with morphological data can illustrate more accurate relationships between mosasaurs and living squamates.

Convergent evolution is very common among unrelated squamates, which creates many rooms for data interpretation; many of these studies had results that often contradicted each other i.

As a result, some scientists chose to completely abandon the utilization of molecular data. A prominent approach was utilized by a multi-author study led by Todd Reeder of San Diego State University : it closely integrated morphological, molecular, and paleontological data in a large dataset to overcome previous conflicts, which revealed less-obvious "hidden" morphological support for molecular results including such that recovered Mosasauria as a sister clade to Serpentes.

Alexander Pyron of The George Washington University in a study, which utilized a novel asymmetric approach of interpreting some problematic morphological datasets alongside molecular data, which ultimately also recovered Mosasauria as a sister clade to the Serpentes.

One of the earliest relevant attempts at an evolutionary study of Mosasaurus was done by Russell , [75] which proposed that Mosasaurus evolved from a Clidastes -like mosasaur, and diverged into two lineages.

Of these two hypothesized lineages, one gave rise to M. In , Bell published the first cladistical study of North American mosasaurs.

In it, he incorporated the species M. Some findings of the study were in agreement with Russell , such as Mosasaurus descending from an ancestral group which Clidastes is a member of and M.

Bell also found that Mosasaurus formed a sister relationship with another group that included Globidens and Prognathodon , and that M. First, the genus was severely underrepresented by incorporating only the three North American species M.

Conrad uniquely utilized only M. This result indicated that M. As a result, some paleontologists caution that lower-classification results from Conrad such as the specific placement of Mosasaurus within the Mosasauria may contain technical problems that can make it inaccurate.

Questo rettile doveva essere uno dei massimi predatori del suo ambiente. Le orbite piccole e gli organi di olfatto poco sviluppati suggeriscono che questo animale fosse un nuotatore di superficie, che preferiva rimanere in acque costiere.

Numerose ferite alle mascelle riscontrate in esemplari fossili suggeriscono che questi animali conducevano uno stile di vita particolarmente violento, probabilmente combattendo fra loro.

This aquatic animal was indeed a fierce looking creature. It was approximately 50 feet long — or longer than a semi-truck trailer and it weighed about 15 tons — or almost twice the weight of an elephant.

To top it off, it had long jaws which were filled with lots of razor-sharp teeth. Teeth that were able to eviscerate anything this animal wanted to eat.

So what exactly did Mosasaurus eat? Well, it ate just about anything it wanted. However, paleontologists believe that its diet consisted of fish, shellfish and squids.
