Real mosasaurus

However, like all things relating to movie depictions of extinct creatures, what you see on screen and what the fossils tell us are two different things, real mosasaurus. This was decades before the first dinosaurs were scientifically described. The idea of extinction was brand new at the time, and these prehistoric lizard jaws provided good support for the notion that species have come and gone on real mosasaurus Earth for a long time.

This Specimen has been sold. This is a very special and awe inspiring fossil, a jaw section yes, a real one from one of the most fearsome predators to ever inhabit our oceans, a Mosasaur. The jaw section is 8 inches long and the largest tooth is about 4 inches including the root. This would have come from a large individual. It has been mounted on a custom made stone and metal stand.

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. As a result, more than fifty species have been attributed to the genus in the past. A redescription of the type specimen in helped resolve the taxonomy issue and confirmed at least five species to be within the genus.

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. A five-year removal process followed, in which researchers separated the sandstone from the fossils. According to Konishi, it ended up being the most complete skeleton of a mosasaur ever found in Japan or the northwestern Pacific.

Mosasaurus was a ferocious predator in the ancient oceans of the Cretaceous period While dinosaurs dominated the land, Mosasaurus used its long tail and stumpy, paddle-like limbs to cruise through the water, devouring all kinds of prey with its massive jaws and sharp, cone-shaped teeth. Mosasaurus is one genus, or group of species, out of dozens that made up a diverse family of marine reptiles called mosasaurs. The mosasaurs ruled the ocean in the late Cretaceous period. They were not sea dinosaurs, but a separate group of reptiles, more closely related to modern snakes and lizards , according to the Philip J. Currie Dinosaur Museum. Mosasaurs went extinct A Mosasaurus species has since been fictionally resurrected on the big screen, most notably in the movie blockbuster "Jurassic World," increasing the profile of this mighty group of marine reptiles.

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. Several different Mosasaurus species have been identified, including M. Mosasaurus is one of the best-known mosasaurs, a group of aquatic lizards that were the dominant marine predators at the end of the Cretaceous Period.
