Even the [Tyrannosaurus rex] bite would be puny by comparison. Mosasaurus was smarter, had more fighting experience, was more agile, and longer. They are placed further toward the back of the skull than in nearly all other mosasaurs (exceeded only by Goronyosaurus), and begin above the fourth or fifth maxillary teeth. The fracture is covered with a nonunion formation of bony callus with shallow scratch marks and a large pit connected to an abscess canal. [7] A particular near-complete skeleton of M. missouriensis is reportedly measured at 6.5 meters (21ft) in total length with a skull approaching 1 meter (3.3ft) in length. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. 1 mo. [11] In 2004, Eric Mulder, Dirk Cornelissen, and Louis Verding suggested M. lemonnieri could be a juvenile form of M. hoffmannii based on the argument that significant differences could be explained by age-based variation. Mosasaurus fossils have been found in places as diverse as North and South America, Europe, Africa, Western Asia, and Antarctica. [49], The forelimbs of Mosasaurus are wide and robust. hoffmannii. "[14] In a 1822 work by James Parkinson, William Daniel Conybeare coined the genus Mosasaurus from the Latin Mosa "Meuse" and the Ancient Greek (saros, "lizard"), all literally meaning "lizard of the Meuse", in reference to the river where the holotype specimen was discovered nearby. (2017). This was based on fossils like the M. missouriensis holotype, which indicated an elastic vertebral column that Goldfuss in 1845 saw as evidence of an ability to walk and interpretations of some phalanges as claws. The region was shallow for a seaway, reaching a maximum depth of about 800900 meters (2,6003,000ft). Due coexistence with other large mosasaurs like Prognathodon, which specialized in robust prey, M. missouriensis likely specialized more on prey best consumed using cutting-adapted teeth in an example of niche partitioning. In recent studies, the confirmation of paleogeographical affinities extended this range to areas across the Atlantic including Brazil and the East Coast state of New Jersey. [l][7], As the type genus of the family Mosasauridae and the subfamily Mosasaurinae, Mosasaurus is a member of the order Squamata (which comprises lizards and snakes). Megalodon only had bite force, size, and bulk. This was likely a severe bone infection initiated by septic arthritis, which progressed to the point where a large portion of the quadrate was reduced to abscess. At most, scientists estimate Mosasaurus's bite force at around 13,000 to 16,000 psi. (2018). The parietal foramen in Mosasaurus, which is associated with the parietal eye, is the smallest among mosasaurids. [47][48][49], The type species, M. hoffmannii, is one of the largest marine reptiles known,[50][46] though knowledge of its skeleton remains incomplete as it is mainly known from skulls. Mosasaurus was 40 feet. The cutting edges in M. hoffmannii and M. missouriensis are finely serrated,[5][10] while in M. conodon and M. lemonnieri serrations do not exist. [114][121], Mosasaurus is known from late Maastrichtian deposits in the Antarctic Peninsula, specifically the Lpez de Bertodano Formation in Seymour Island. They do not exhibit the bone mass increase found in juvenile primitive mosasauroids to support buoyancy associated with a lifestyle in shallow water, implying that Mosasaurus was precocial: they were already efficient swimmers and lived fully functional lifestyles in open water at a very young age, and did not require nursery areas to raise their young. [50] The texture of the bones is virtually identical with in modern whales, which indicates Mosasaurus possessed a high range of aquatic adaptation and neutral buoyancy as seen in cetaceans. This, along with signs of healing, indicates that the fractures were not imminently fatal. 00:00 / 00:00. [102][106], The southern Tethyan margin was located along the equator between 20N and 20S, resulting in warmer tropical climates. has also been described. [42], Like all mosasaurs, Mosasaurus had four types of teeth, classified based on the jaw bones they were located on. As the proposal remains restricted to a PhD thesis, it is defined as an unpublished work per Article 8 of the ICZN and therefore is not yet formally valid. 241.

[76] In 2014, Konishi and colleagues expressed a number of concerns with the reliance on Bell's study. It is geographically subdivided into two biogeographic provinces that respectively include the northern and southern Tethyan margins. Together with the formation of a nutrient-rich deepwater mass from the mixing of continental freshwater, Arctic waters from the north, and warmer saline Tethyan waters from the south, this created a warm and productive seaway that supported a rich diversity of marine life. First, M. lemonnieri fossils are endemic to Belgium and the Netherlands, which despite the famous discovery of the M. hoffmannii holotype attracted little attention from mosasaur paleontologists. [90] Likewise, an M. missouriensis skeleton has a tooth from another M. missouriensis embedded in the lower jaw underneath the eye. Another five species still nominally classified within Mosasaurus are planned to be reassessed in a future study. He contacted the prominent biologist Petrus Camper, and the skull gained international attention after Camper published a study identifying it as a whale. One such bone is a quadrate (NHMM 003892) which is 150% larger than the average size, which Everhart and colleagues in 2016 reported can be extrapolated to scale an individual around 18 meters (59ft) in length. [7][36] Compared to other mosasaurs, the rib cage of Mosasaurus is unusually deep and forms an almost perfect semicircle, giving it a barrel-shaped chest. Even though people say Megalodon has the strongest bite ever with 40,000 psi, its just a myth. maximus-hoffmanni. Who Would Win Mosasaurus Vs Spinosaurus? [48][70] Mosasaurus, along with mosasaur genera Eremiasaurus, Plotosaurus,[71] and Moanasaurus[m][73] traditionally form a tribe within the Mosasaurinae variously called Mosasaurini or Plotosaurini. [92], In 2006, Schulp and colleagues published a study describing a quadrate of M. hoffmannii with multiple unnatural openings and an estimated 0.5 liters (0.13U.S.gal) of tissue destroyed. The magnus adductor muscles, which attach to the lower jaws to the cranium and have a major role in biting function, are massive, indicating M. hoffmannii was capable of enormous bite forces. [50], In modern lizards, the mechanical build of the skull is characterized by a four-pivot geometric structure in the cranium that allows flexible movement of the jaws, possibly to allow the animals to better position them and prevent prey escape when hunting. [8] The early history of the genus as a taxon was subject to complications spurred by the infamous rivalry between American paleontologists Edward Drinker Cope and Othniel Charles Marsh during the Bone Wars. and that their bite force didnt matter but the 'venom' they inflicted did.I havent seen any paper on mosasaurs having venom. While M. hoffmannii also preyed on turtles, its teeth were built to handle a wider range of prey less suited for P. [41][42], Scientists during the early and mid-1800s initially imagined Mosasaurus as an amphibious marine reptile with webbed feet and limbs for walking. Extensive amounts of bone reparative tissue were also present, suggesting the infection and subsequent healing process may have progressed for a few months. M. hoffmannii and Prognathodon sectorius were the dominant species in the northern province. [53], The skull of Mosasaurus is conical and tapers off to a short snout which extends a little beyond the frontmost teeth. In addition, they exclusively feature M. conodon, Halisaurus platyspondylus and Prognathodon rapax. Various partial skeletons of M. conodon, M. hoffmannii, and M. missouriensis suggest M. conodon likely had up to thirty-six dorsal vertebrae and nine pygal vertebrae; M. hoffmannii had likely up to thirty-two dorsal vertebrae and ten pygal vertebrae;[i][11][36] and M. missouriensis around thirty-three dorsal vertebrae, eleven pygal vertebrae, and at least seventy-nine caudal vertebrae. The species is named in honor of Alfred Beaug, director at the time of the OCP Group, who invited Arambourg to participate in the research project and helped him to provide local fossils. In this case, there were signs of healing around the wound, implying survival of the incident. To give you some perspective, the average human can exert a force as great as 268 pounds per square inch (psi) using their molars. 189K views 1 year ago #Mosasaurus #Megalodon #VS If these ancient aquatic animals fought today, who would win? [50][36] Rather, M. hoffmannii likely employed inertial feeding (in which the animal thrusts its head and neck backward to release a held prey item and immediately thrust the head and neck forward to close the jaws around the item[78]) and used jaw adduction to assist in biting during prey seizure. [2], Distribution, ecosystem, and ecological impact. saturator. [50], Mosasaurus swam using its tail. [112][103][113], In what is now Alabama within the Southern Interior Subprovince, most of the key genera including sharks like Cretoxyrhina and the mosasaurs Clidastes, Tylosaurus, Globidens, Halisaurus, and Platecarpus disappeared and were replaced by Mosasaurus. These localities are all shallow ocean deposits, suggesting that juvenile Mosasaurus may still have lived in shallow waters.[100]. The force of its bite was remarkably powerful: 11,000 pounds. Fossil evidence suggests Mosasaurus inhabited much of the Atlantic Ocean and the seaways adjacent to it. Its tail was long and ended in a downward bend and a paddle-like fluke. The Mosasaurus had 250 teeth, and scientists estimate its bite force at around 13,000 to 16,000 psi. In 2004, Lingham-Soliar observed that if these injuries were indeed the result of an intraspecific attack, then there is a pattern of them concentrating in the skull region. (Interestingly, the dog you'd expect to see on this list, the pit bull, can only muster a bite force of 250 PSI, about the same as a full-grown human.) Mosasaurus (/mozsrs/; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles. At the time, Europe was a scattering of islands with most of the modern continental landmass being underwater. [58][91], Attacks by another Mosasaurus are a possible cause of physical pathologies in other skulls, but they could have instead arisen from other incidents like attempted biting on hard turtle shells. [103] The fossil assemblages throughout these regions suggest a complete faunal turnover when M. missouriensis and M. conodon appeared at 79.5 Ma, indicating that the presence of Mosasaurus in the Western Interior Seaway had a profound impact on the restructuring of marine ecosystems. This is significantly higher than the bite force of the largest shark species, the great white shark, which is estimated to be arund 1,950 psi. Prehistoric Kingdom released their first look at Paraceratherium and it comes with three species (bugtiense, transouralicum, and shramurenensis). [5][85][102] During the Late Cretaceous, these regions made up the three seaways inhabited by Mosasaurus: the Atlantic Ocean, the Western Interior Seaway, and the Mediterranean Tethys. A third hypothesis proposes that the layer is a lag deposit of Cretaceous sediments forced out by a strong impact by a tsunami, and what remained was subsequently refilled with Cenozoic fossils. Lingham-Soliar may have misapplied the ratio. [5], The palate, which consists of the pterygoid bones, palatine bone, and nearby processes of other bones, is tightly packed to provide greater cranial stability. Other marine reptiles such as the marine monitor lizard Pachyvaranus and the sea snake Palaeophis are known there. [50] It is unlikely Mosasaurus was a scavenger as it had a poor sense of smell. On the upper jaw, there were three types: the premaxillary teeth, maxillary teeth, and pterygoid teeth. [42] One indeterminate specimen of Mosasaurus similar to M. conodon from the Pembina Gorge State Recreation Area in North Dakota was found to have an unusual count of sixteen pterygoid teeth, far greater than in known species. Many elements of the sculpture can be considered inaccurate, even for the time. [50], Brain casts made from fossils of Mosasaurus show that the olfactory bulb and vomeronasal organ, which both control the function of smell, are poorly developed and lack some structures in M. hoffmannii; this indicates the species had a poor sense of smell. The scientists utilized an interpretation that differences in isotope values can help explain the level of resource partitioning because it is influenced by multiple environmental factors such as lifestyle, diet, and habitat preference. However, there are differences in tooth spacing between both bites which indicate different jaw sizes. (2014) estimated that M. missouriensis may have measured up to 89 meters (2630ft) in length. The margin provided a warm-temperate climate with habitats dominated by mosasaurs and sea turtles. There are some other species of mosasaur that specialised in eating this kind of prey so they had stronger bites than Mosasaurus who was a generalist predator so it would take anything that fit into its mouth, not unlike tiger sharks today. [53] Based on personal observations of various unpublished fossils from Morocco, Nathalie Bardet estimated that M. beaugei grew to a total length of 810 meters (2633ft), their skulls typically measuring around 1 meter (3.3ft) in length,[59] with a body mass of around 1.5 metric tons (1.7 short tons) per Paul (2022). Megalodon does have thick skin, but the truth is Mosasaurus teeth are designed to bite through shark skin. [50] As a result, the rear portions of the maxilla (the main tooth-bearing bone of the upper jaw) lack the dorsal concavity that would fit the nostrils in typical mosasaurs. Mosasaurus probably had a strong bite force due to eating prey like giant turtles in its time. Cuvier did not designate a scientific name for the new animal, and this was done by William Daniel Conybeare in 1822 when he named it Mosasaurus in reference to its origin in fossil deposits near the Meuse River. Changing temperatures and an abundance in marine life were characteristic of these localities. Short of dismembering its prey by the sheer force of its bite, a mosasaur had to swallow whatever it caught whole, much like a modern snake. [50][61] Tylosaurus bernardi, the only surviving species of the genus during the Maastrichtian, measured up to 12.2 meters (40ft) in length[127] while the largest coexisting species of Prognathodon like P. saturator exceeded 12 meters (39ft). This giant shark is 25 m in length (82 ft) and swims up to 17 m/s (55 ft/s). ago. This level of bone infection would have been tremendously painful and severely hampered the mosasaur's ability to use its jaws. As such, it had a streamlined body, an elongated tail ending with a downturn supporting a two-lobed fin, and two pairs of flippers. Paleontologists believe its diet would have included virtually any animal; it likely preyed on bony fish, sharks, cephalopods, birds, and other marine reptiles including sea turtles and other mosasaurs. [11] The ilium is rod-like and slender; in M. missouriensis, it is around 1.5 times longer than the femur. These cranial structures are united by strong interlocking sutures formed to resist compression and shear forces caused by a downward thrust of the lower jaw muscles or an upward thrust of prey. An alternate explanation postulates the bite marks as from one individual mosasaur that lightly bit the nautiloid at first, then proceeded to bite again with greater force. Spinosaurus is larger than the T-Rex, but the T-Rex has a far deadlier bite. [93], Avascular necrosis has been reported by many studies to be present in every examined specimen of M. lemonnieri and M. Mosasaurus was among the largest marine animals of its time,[50] and with its large, robust cutting teeth, scientists believe larger members of the genus would have been able to handle virtually any animal. [7], In 1995, Lingham-Soliar studied the head musculature of M. hoffmannii. [55] Paul (2022) offered a larger maximum estimate for the species at 12 meters (39ft) in length and 4.5 metric tons (5.0 short tons) in body mass. maximus, M. missouriensis, and M. conodon; by doing so, others like M. lemonnieri, which is one of the most completely known species in the genus, were neglected, which affected phylogenetic results. [7][36] Despite being the best anatomically represented species, M. lemonnieri was largely ignored in scientific literature. [88][126] To account for this, a 2014 study by T. Lynn Harrell Jr. and Alberto Perez-Huerta examined the concentration ratios of neodymium, gadolinium, and ytterbium in M. hoffmannii and Mosasaurus sp. There is also evidence of aggressive interspecific combat between Mosasaurus and other large mosasaur species. An examination of existing historical evidence by Pieters et al., (2012) suggested the most accurate date would be on or around 1780. [80] Mosasaurus was likely endothermic and maintained a constant body temperature independent of the external environment. Nevertheless, fossils of other mosasaurs with invariable avascular necrosis still exhibit substantial adaptations like eardrums that were well-protected from rapid changes in pressure. The fossils were found in association with fossils of Squalicorax, Enchodus, and various ammonites within a uniquely fossil-rich bed at the base of the Hornerstown Formation known as the Main Fossiliferous Layer. [50] Chemical and structural data in the fossils of M. lemonnieri and M. conodon suggests they may have also hunted in deeper waters. In M. lemonnieri, these olfactory organs, although still small, are better developed and have some components lacking in M. hoffmannii. [54], M. missouriensis and M. lemonnieri are smaller than M. hoffmannii but are known from more complete fossils. "The only plausible attacker with sufficient bite force to penetrate the cortical bone to such an extent is another mosasaur," Bastiaans and his team concluded, identifying the wound as a "tooth strike lesion." The infection ended up being worse than the bite. Agnete Weinreich Carlsen considered it the simplest explanation that such conditions were a product of inadequate anatomical adaptation. The exact affinities of Mosasaurus as a squamate remain controversial, and scientists continue to debate whether its closest living relatives are monitor lizards or snakes. [77] However, the study used a method unorthodox to traditional phylogenetic studies on mosasaur species because its focus was on the relationships of entire squamate groups rather than mosasaur classification. [22] He coined the specific epithet and initially identified it as a species of Ichthyosaurus[28] but later as an amphibian. It was not stated whether they applied Russell's 1967 ratio. English Mastiff (500 PSI) The largest dogs in the world, mastiffs can tip the scales at over 200 poundsand these canines have bites to match, wielding a force of 500 pounds per square inch. [49], The tail structure of Mosasaurus is similar to relatives like Prognathodon, in which soft tissue evidence for a two-lobed tail is known. hoffmannii. [38][55] He also measured the dimensions of IRSNB 3119 and recorded that the skull constituted approximately one-eleventh of the whole body. [5] The quadrate also housed the hearing structures, with the eardrum residing within a round and concave depression in the outer surface called the tympanic ala.[60] The trachea likely stretched from the esophagus to below the back end of the lower jaw's coronoid process, where it split into smaller pairs of bronchi which extended parallel to each other. [102], Many of the earliest fossils of Mosasaurus were found in Campanian stage deposits in North America, including the Western Interior Seaway, an inland sea which once flowed through what is now the central United States and Canada, and connected the Arctic Ocean to the modern-day Gulf of Mexico. But especially compared to those in M. lemonnieri, the pterygoid teeth in M. hoffmannii are relatively small, which indicates ratchet feeding was relatively unimportant to its hunting and feeding. 15. r/Paleontology. [53] Polcyn et al. "The science of the Crystal Palace Dinosaurs, part 2: "The world's first dinosaur park: what the Victorians got right and wrong", "Convergent Evolution in Aquatic Tetrapods: Insights from an Exceptional Fossil Mosasaur". The mosasaur is disadvantaged in almost every aspect. [96], It is likely that Mosasaurus was viviparous (giving live birth) like most modern mammals today.

The validity of some of these genera is disputed as they are primarily based on isolated teeth. Second, the species was overshadowed by the more famous and history-rich type species. Paleontologists have done some sort of biomechanical modeling based on teeth we've found, and they calculated the bite force would be about 40,000 pounds per square inch, which is by far the highest bite force ever calculated for any animal, living or extinct. [11] The disparity is also reflected in the dentary, the lower jawbone,[36] although all species share a long and straight dentary. The dentaries' condition suggests that the species may have had an efficient process of immobilizing the fracture during healing, which helped prevent damage to vital blood vessels and nerves. It likely preferred to hunt in open water near the surface. The team then used computer models to reconstruct the dinosaur's jaw muscles and analyze bite performance. The animal was a mosasaur, an extinct, marine. Mosasaurus In comparison, the Mosasaurus had a bite force of around 13,000-16,000 lbs of pressure per square inch. Unfortunately for Mosasaurus, few animals match Megalodon when it comes to sheer bite force. The skull of Mosasaurus was equipped with robust jaws capable of swinging back and forth and strong muscles capable of powerful bites using dozens of large teeth adapted for cutting prey. He clarified that earlier interpretations of claws were erroneous and demonstrated how the phalanges show no indication of muscle or tendon attachment, which would make walking impossible. [97][98] Microanatomical studies on bones of juvenile Mosasaurus and related genera have found that their bone structures are comparable to adults. These species include one comparable with M. lemonnieri, and another that appears to be closely related to M. [q] Two of these cases displayed irregular surface deformities around the fusion site caused by drainage of the vertebral sinuses, which is indicative of a bone infection. A recently described fossil of the ocean-dwelling beast reveals that its bite was unlike that of any of its relatives, in the water or onshore. There were still conflicts among them, as an instance of Tylosaurus attacking a Mosasaurus has been documented. It was hypothesized that these adaptations helped maintain resource partitioning between the two mosasaurs. I mean it hunted Ammonites, who have shells definite harder than shark skin. The earliest fossils of Mosasaurus known to science were found as skulls in a chalk quarry near the Dutch city of Maastricht in the late 18th century, which were initially thought to have been the bones of crocodiles or whales. [95], Unnatural fusion of tail vertebrae has been documented in Mosasaurus, which occurs when the bones remodel themselves after damage from trauma or disease. [10] In M. missouriensis, the bar is robust and does not constrict. [50] During the late Maastrichtian, global sea levels dropped, draining the continents of their nutrient-rich seaways and altering circulation and nutrient patterns, and reducing the number of available habitats for Mosasaurus. [30], Mosasaurus was a type of derived mosasaur, or a latecoming member with advanced evolutionary traits such as a fully aquatic lifestyle. That title goes to the Dunkleosteus, the real king of the sea when it comes to biting, his jaw could exert aproximately 80,000 psi, which doubles Megalodon and it is because Dunkleosteus' head was specially designed for compressing, its teeth had a special razor design, and it wasnt entirely teeth . This formed through a combination of catastrophic seismic and geological disturbances, mega-hurricanes, and giant tsunamis caused by the impact of the Chicxulub asteroid that catalyzed the K-Pg extinction event. According to one hypothesis, the fossils may have originated from an earlier Cretaceous deposit and were reworked into the Paleocene formation during its early deposition. It did not take into account Golduss' 1845 study of M. missouriensis which instead called for a narrower skull, nostrils at the top of the skull, and amphibious terrestrial limbs (the latter being incorrect in modern standards[44]). It would have had a stronger bite than something like a Spinosaur, but it's bite force was notably inferior to a similarly sized Tyr. First, the genus was severely underrepresented by incorporating only the three North American species M. hoffmannii/M. Such a trait is unique among squamates, the only known exception being the Argentine black and white tegu, which can maintain partial endothermy. [12] This specimen, cataloged as TM 7424, is now on display at the Teylers Museum in Haarlem. The femur itself is about twice as long as it is wide and ends at the distal side in a pair of distinct articular facets (of which one connects to the ilium and the other to the paddle bones) that meet at an angle of approximately 120. Did mosasaurus actually have a stronger bite force than t rex? Join. Its tapered jaw measured around 4ft in length and could reach opening widths of around 3ft. Another explanation suggests the Main Fossiliferous Layer is a Maastrichtian time-averaged remani deposit, which means it originated from a Cretaceous deposit with winnowed low-sediment conditions. [16] The skull became part of Cuvier's first speculations about the conception of extinction, which later led to his theory of catastrophism, a precursor to the theory of evolution. Theagarten Lingham-Soliar suggested two reasons for this neglect. On the lower jaw, only one type, the dentary teeth, were present.
