Real mosasaurus

This Specimen has been sold. This is a very special and awe inspiring fossil, a jaw section yes, real mosasaurus, a real one from one of the most fearsome predators to ever inhabit our oceans, a Mosasaur.

Being the size of a great white shark, the Wakayama Soryu Megapterygius wakayamaensis would undoubtedly make an eye-catching first impression on anyone. Takuya Konishi, an associate professor at the University of Cincinnati, spearheaded the task of classifying the mosasaur and chronicling its prehistoric rule. Konishi and a group of international co-authors recently published a description of the Wakayama Soryu in the Journal of Systematic Paleontology. As he was scouring the river for ammonite fossils, a dark bone embedded in sandstone caught his eye. An examination of the bone revealed it to be a vertebra belonging to a nearly complete mosasaur skeleton.

Real mosasaurus

It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous. The genus was one of the first Mesozoic marine reptiles known to science—the first fossils of Mosasaurus were found as skulls in a chalk quarry near the Dutch city of Maastricht in the late 18th century, and were initially thought to be crocodiles or whales. One skull discovered around was famously nicknamed the "great animal of Maastricht". In , naturalist Georges Cuvier concluded that it belonged to a giant marine lizard with similarities to monitor lizards but otherwise unlike any known living animal. This concept was revolutionary at the time and helped support the then-developing ideas of extinction. Cuvier did not designate a scientific name for the animal; this was done by William Daniel Conybeare in when he named it Mosasaurus in reference to its origin in fossil deposits near the Meuse River. 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. Traditional interpretations have estimated the maximum length of the largest species, M. The skull of Mosasaurus had robust jaws and strong muscles capable of powerful bites using dozens of large teeth adapted for cutting prey. Its four limbs were shaped into paddles to steer the animal underwater. Its tail was long and ended in a downward bend and a paddle-like fluke. Mosasaurus possessed excellent vision to compensate for its poor sense of smell, and a high metabolic rate suggesting it was endothermic "warm-blooded" , an adaptation in squamates only found in mosasaurs. There is considerable morphological variability across the currently-recognized species in Mosasaurus —from the robustly-built M.

Mosasaurus facts and pictures. Discover a fearsome mosasaur from the Late Cretaceous, made famous by its appearance in the film Jurassic World Mosasaurus is an extinct aquatic reptile that lived at the very end of the Cretaceous Period, from around Mosasaurus was not a dinosaur; like other mosasaurs, it was descended from lizards that originally lived on land. Because of this, Mosasaurus belongs to the reptilian order Squamata, which contains all lizards and snakes. Mosasaurus is not a species; it is a genus. A genus is a group of closely related animals.

Francis; Jon Ineson; Rowan J. Globidens dakotensis. However, it is possible that such specimens may actually represent Moanasaurus , although this depends on the outcome of a pending revision of the genus. There is considerable morphological variability across the currently-recognized species in Mosasaurus —from the robustly-built M. It may not have been impossible for Mosasaurus to have launched itself out of the water to snatch flying prey from the air as is seen in the film, but I suspect that if it did happen, it was a rare occurrence. Reguero Raub; Joseph L. Transactions of the Kansas Academy of Science. Theagarten Lingham-Soliar suggested two reasons for this neglect. A look into the gaping jaws of the Mosasaurus from Jurassic World shows some interesting features as well. However, only four specimens were studied.

This was during a time when sea levels were much higher than today. The foramina along the snout form a pattern similar to the foramina in Clidastes skulls. Academic Press. The third species was described in 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 congeneric relationship was eventually confirmed by James Ellsworth De Kay in , [25] and the New Jersey fossil was named Mosasaurus dekayi in his honor. The neurocranium housed a brain which was narrow and relatively small compared to other mosasaurs. Mark Witton. Nevertheless, fossils of other mosasaurs with invariable avascular necrosis still exhibit substantial adaptations like eardrums that were well-protected from rapid changes in pressure.
