The Mosasaurus is also thought to have had short arms with . "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. Mosasaurus was 40 feet. conodon. [65] Chemical studies conducted on a M. hoffmannii maxillary tooth measured an average rate of deposition of odontoblasts, the cells responsible for the formation of dentin, at 10.9 micrometers (0.00043in) per day. hoffmannii. Mosasaurus fossils have been found in places as diverse as North and South America, Europe, Africa, Western Asia, and Antarctica. The discovery of mosasaurus fossils has helped us better understand the ancient marine ecosystem. Laelaps . The cause of the infection remains unknown, but if it were a result of an intraspecific attack then it is possible one of the openings on the quadrate may have been the point of entry for an attacker's tooth from which the infection entered. They were described by Dollo in later papers. In many mosasaurs like Prognathodon and M. lemonnieri, this function mainly served to allow ratchet feeding, in which the pterygoid and jaws would "walk" captured prey into the mouth like a conveyor belt. [123] Prognathodon and Globidens are also expected to be present based on distribution trends of both genera, although conclusive fossils have yet to be found. His calculations interpreted "body length" as the length of the postcranial body, not the total length of the animal as demonstrated in Russell (1967), This erroneously inflated the estimate by 10%. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. This enabled these monster sharks to munch . [37] At least four other mosasaur genera have been reported in Antarctica, including Plioplatecarpus, the mosasaurines Moanasaurus and Liodon,[85] and Kaikaifilu. The study found a dietary divide between M. missouriensis and Prognathodon overtoni based on stomach contents. [13][20] In 1829, Gideon Mantell added the specific epithet hoffmannii, in honor to Hoffmann. Mosasaurus hoffmannii v Pliosaurus funkei - Carnivora The genus adapted by accessing new habitats in more open waters. [53] Based on personal observations of various unpublished fossils from Morocco, Nathalie Bardet estimated that M. beaugei grew to a total length of 810 meters (2633ft), their skulls typically measuring around 1 meter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). [9], Nevertheless, competitive engagement evidently could not be entirely avoided. [11] The ilium is rod-like and slender; in M. missouriensis, it is around 1.5 times longer than the femur. Lingham-Soliar may have misapplied the ratio. Mosasaurus faced competition with other large predatory mosasaurs such as Prognathodon and Tylosauruswhich were known to feed on similar preythough they were able to coexist in the same ecosystems through niche partitioning. [96], It is likely that Mosasaurus was viviparous (giving live birth) like most modern mammals today. What is the strongest bite force of all time that we know of - Reddit A new analysis published on Wednesday of fossils of the creature unearthed in 1975 has determined that it deserves to be recognized as a new genus of mosasaur based on skeletal traits including a. Megalodon was 63 feet. In a 1798 narrative of this event by Barthlemy Faujas de Saint-Fond, the skull was allegedly retrieved by twelve grenadiers in exchange for an offer of 600 bottles of wine. [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. As a result, more than fifty different species have been attributed to the genus in the past. How much bite force does a hyena have? Agnete Weinreich Carlsen considered it the simplest explanation that such conditions were a product of inadequate anatomical adaptation. 189K views 1 year ago #Mosasaurus #Megalodon #VS If these ancient aquatic animals fought today, who would win? [38][71][74], One of the earliest relevant attempts at an evolutionary study of Mosasaurus was done by Russell in 1967. As a result, some paleontologists caution that lower-order classification results from Conrad's 2008 study such as the specific placement of Mosasaurus may contain technical problems, making them inaccurate. Seabeds bordering the cratons in Africa and Arabia and extending to the Levant and Brazil provided vast shallow marine environments. 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. [22] Richard Ellis speculated in 2003 that this may have been the earliest discovery of the second species M. missouriensis,[23] although competing speculations exist. Its tapered jaw measured around 4ft in length and could reach opening widths of around 3ft. [33], The fourth species M. lemonnieri was first detected by Camper Jr. based on fossils from his father's collections, which he discussed with Cuvier during their 1799 correspondence, but Cuvier rejected the idea of another Mosasaurus species. Many of the Mosasaurus fossils from the Main Fossiliferous Layer consist of isolated bones commonly abraded and worn, but the layer also yielded better-preserved Mosasaurus remains. [38] In a 2000 study, Lingham-Soliar refuted this based on a comprehensive study of existing M. lemonnieri specimens,[36] which was corroborated by a study on the M. conodon skull by Takehito Ikejiri and Spencer G. Lucas in 2014. [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. What If the Megalodon Shark Fought the Mosasaurus? Ancient Predator Had Strongest Bite Of Any Fish - ScienceDaily Mosasaurus gave its name to a group of marine lizards - Mosasaurs. Did mosasaurus actually have a stronger bite force than t rex? Reptile dubbed 'Jaws of Death' terrorized Cretaceous seas hoffmannii had two to three prisms on the labial side (the side facing outwards) and no prisms on the lingual side (the side facing the tongue), M. missouriensis had four to six labial prisms and eight lingual prisms, M. lemonnieri had eight to ten labial prisms, and M. beaugei had three to five labial prisms and eight to nine lingual prisms. [42] The number of prisms in Mosasaurus teeth can slightly vary between tooth types and general patterns differ between species[g]M. [56][57] Street (2016) noted that large M. missouriensis individuals typically had skulls exceeding lengths of 1 meter (3.3ft). Traditional interpretations have estimated the maximum length of the largest species, M. hoffmannii, to be up to 17.1 meters (56ft), making it one of the largest mosasaurs, although some scientists consider this an overestimation with recent estimates suggesting a length closer to 13 meters (43ft). [95], Unnatural fusion of tail vertebrae has been documented in Mosasaurus, which occurs when the bones remodel themselves after damage from trauma or disease. 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. [131], M. hoffmannii fossils have been found within the K-Pg boundary itself in southeastern Missouri between the Paleocene Clayton Formation and Cretaceous Owl Creek Formation. However, there are differences in tooth spacing between both bites which indicate different jaw sizes. The latter rendered Mosasaurus paraphyletic (an unnatural grouping), but Bell (1997) nevertheless recognized Plotosaurus as a distinct genus. Another trait that came from Tyrannosaurus being in its gene pool was the massively strong bite force it had, . 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. [35][33] Further mining of the quarry in subsequent years uncovered many additional well-preserved fossils, including multiple partial skeletons which collectively represented nearly the entire skeleton of the species. On the upper jaw, there were three types: the premaxillary teeth, maxillary teeth, and pterygoid teeth. Fossil vertebrae from the layer were found with fractures formed after death. This fish was much longer than the length of the mosasaur's skull, which measured 66 centimeters (26in) in length, confirming that M. missouriensis consumed prey larger than its head by dismembering and consuming bits at a time. A 2017 study by Hallie Street and Michael Caldwell performed the first proper diagnosis and description of the M. hoffmannii holotype, which allowed a major taxonomic cleanup confirming five species as likely validM. Mosasaurus had a transatlantic distribution, with its fossils having been found in marine deposits on both sides of the Atlantic Ocean. [22], The third species was described in 1881 from fragmentary fossils in New Jersey by Edward Drinker Cope, who thought it was a giant species of Clidastes and named it Clidastes conodon. "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". hoffmannii. (2018). Megalodon is coming into the ring with a brutal bite force of 275,000 kPa. 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. The oceanic climate of the Northern Interior Subprovince was likely a cool temperate one, while the Southern Interior Subprovince had warm temperate to subtropical climates. [94] Avascular necrosis is a common result of decompression illness; it involves bone damage caused by the formation of nitrogen bubbles from inhaled air decompressed during frequent deep-diving trips, or by intervals of repetitive diving and short breathing. [50] The quadrate bone, which connected the lower jaw to the rest of the skull and formed the jaw joint, is tall and somewhat rectangular in shape, differing from the rounder quadrates found in typical mosasaurs. There is considerable morphological variability across the currently-recognized species in Mosasaurusfrom the robustly-built M. hoffmannii to the slender and serpentine M. lemonnieribut an unclear diagnosis (description of distinguishing features) of the type species M. hoffmannii led to a historically problematic classification. The layer was likely deposited as a tsunamite, alternatively nicknamed the "Cretaceous cocktail deposit". The T. rex carried out a heavy assault on Indominus, and the two dinosaurs engaged in a ferocious battle. Megalodon VS Mosasaurus - YouTube T. Rex Bite Strongest Ever on LandTen Times Greater Than Gator's [129], One enigmatic occurrence of Mosasaurus sp. An examination of existing historical evidence by Pieters et al., (2012) suggested the most accurate date would be on or around 1780. Mosasaur - Wikipedia 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]). [97] Such fossil records, along with a total absence of any evidence suggesting external egg-based reproduction, indicates the likeliness of viviparity in Mosasaurus. [16][17][18] This caught the attention of French revolutionaries, who looted the fossil following the capture of Maastricht during the French Revolutionary Wars in 1794. Mosasaurus (/mozsrs/; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles.

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. hoffmannii had fourteen to sixteen maxillary teeth, fourteen to fifteen dentary teeth, and eight pterygoid teeth;[11][46][50] M. missouriensis had fourteen to fifteen maxillary teeth, fourteen to fifteen dentary teeth, and eight to nine pterygoid teeth;[9][42][64] M. conodon had fourteen to fifteen maxillary teeth, sixteen to seventeen dentary teeth, and eight pterygoid teeth;[11][42] M. lemonnieri had fifteen maxillary teeth, fourteen to seventeen dentary teeth, and eleven to twelve pterygoid teeth;[36][11][42] and M. beaugei had twelve to thirteen maxillary teeth, fourteen to sixteen dentary teeth, and six or more pterygoid teeth. These environments were dominated by mosasaurs and marine side-necked turtles. For example, the braincase of the mosasaur Plioplatecarpus marshi provided for a brain around twice the size of that in M. hoffmannii despite being only half the length of the latter. [99][97] Some areas in Europe and South Dakota have yielded concentrated assemblages of juvenile M. hoffmannii, M. missouriensis and/or M. lemonnieri. Fossil sea monster's bite makes T-Rex look feeble | Reuters ; SDSM 452)[7][11] has seven cervical (neck) vertebrae, thirty-eight dorsal vertebrae (which includes thoracic and lumbar vertebrae) in the back, and eight pygal vertebrae (front tail vertebrae lacking haemal arches) followed by sixty-eight caudal vertebrae in the tail. 19 Facts About Mosasaurus [2023] - BlogDigger The 10 Strongest Bites in the Animal Kingdom - ThoughtCo Considering how the individual was able to survive such conditions for an extended period of time, Schulp and colleagues speculated it switched to a foraging-type diet of soft-bodied prey like squid that could be swallowed whole to minimize jaw use.
