Megalodon VS Mosasaurus - YouTube Comparisons between the 13C levels in multiple teeth of M. hoffmannii and P. saturator from the Maastrichtian-age Maastricht Formation showed that while there was some convergence between certain specimens, the average 13C values between the two species were on average different. Mosasaurs (from Latin Mosa meaning the ' Meuse ', and Greek sauros meaning 'lizard') comprise a group of extinct, large marine reptiles from the Late Cretaceous. [7][9] Third, there was still a lack of comparative studies of the skeletal anatomy of large mosasaurines at the time. [102][103][104] The wide range of oceanic climates yielded a large diversity of fauna that coexisted with Mosasaurus. The 10 Strongest Bites in the Animal Kingdom - ThoughtCo 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. [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. [129], One enigmatic occurrence of Mosasaurus sp. The two mosasaurs Mosasaurus and Prognathodon appear to have been the dominant taxa, being widespread and ecologically diversified throughout the seaway. Modern crocodiles commonly attack each other by grappling an opponent's head using their jaws, and Lingham-Soliar hypothesized that Mosasaurus employed similar head-grappling behavior during intraspecific combat. Could the star of The Meg really bite a ship in half? We took a Mosasaurus probably had a strong bite force due to eating prey like giant turtles in its time. The force of its bite was remarkably powerful: 11,000 pounds. 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. [61] Lingham-Soliar (1995) suggested that Mosasaurus had a rather "savage" feeding behavior as demonstrated by large tooth marks on scutes of the giant sea turtle Allopleuron hoffmanni and fossils of re-healed fractured jaws in M. The team then used computer models to reconstruct the dinosaur's jaw muscles and analyze bite performance. Fossil vertebrae from the layer were found with fractures formed after death. Prognathodon had a robust and heavy jaw that would have been capable of withstanding a high bite force supplied by powerful jaw muscles. However it's the teeth that should receive . [49], The tail structure of Mosasaurus is similar to relatives like Prognathodon, in which soft tissue evidence for a two-lobed tail is known. The swimming style was likely sub-carangiform, which is exemplified today by mackerels. This creates a rigid three-pivot geometric cranial structure. Mosasaurus means 'Meuse lizard', referring to the river near which it was first found. Teeth were constantly shed through a process where the replacement tooth developed within the root of the original tooth and then pushed it out of the jaw. The 2015 Indominus roaring at the T. rex and Blue seconds before she is pulled to her death by a Mosasaurus. [61], Another case of presumed niche partitioning between Mosasaurus and Prognathodon from the Bearpaw Formation in Alberta was documented in a 2014 study by Konishi and colleagues.
