Real mosasaurus

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, real mosasaurus associate professor at the University of Cincinnati, spearheaded the task of classifying the mosasaur and chronicling its prehistoric rule.

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.

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. 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 the Earth for a long time. But deciphering the ever-changing tree of lizard squamate relationships is far beyond the scope of this blog. All known mosasaur species date back to no later than the second half of the Cretaceous, but they seem to have done quite well up until the KT extinction that wiped them out along with so many of those other weird and nifty prehistoric reptiles. Mosasaurs tend to turn up in rocks laid down in relatively shallow marine environments. It seems like they inhabited regions near coastlines, lagoons, and estuaries where they prowled the waters for fish including sharks , ammonites, birds, and other marine reptiles like plesiosaurs and turtles. Some species, like the round-toothed Globidens , probably specialized in feeding on mollusks, using their blunt teeth to crack the shells of their prey. This was during a time when sea levels were much higher than today. Places like North Africa, the Middle East, and the North American prairies, all high and dry now, were once home to mosasaurs. Though they coexitsted with a variety of other large aquatic predators such as sharks, crocodiles, and plesiosaurs, large mosasaurs appear to have been near the top of the Cretaceous marine food chains.

The margin provided a warm-temperate climate with habitats dominated by mosasaurs and sea turtles.

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. The stone base is made out of fossiliferous rock and you can see fossils of Orthoceras a straight cephalopod in it. They are crudely constructed using plaster or modern animal bones with real Mosasaurus teeth mounted in them.

Get the facts about this enormous ocean-dwelling creature. This ocean-dwelling creature is from the late Cretaceous period 70 to 65 million years ago. It's distinguishing characteristics included a blunt, alligator-like head, fin on the end of its tail, and a hydrodynamic build. It was large—up to 50 feet long and weighing 15 tons—and subsisted on a diet of fish, squid, and shellfish. The remains of Mosasaurus were discovered well before educated society knew anything about evolution, dinosaurs, or marine reptiles—in a mine in Holland in the late 18th century hence this creature's name, in honor of the nearby Meuse River. Importantly, the unearthing of these fossils led early naturalists like Georges Cuvier to speculate, for the first time, about the possibility of species going extinct, which flew in the face of accepted religious dogma of the time. Until the late Enlightenment, most educated people believed that God created all the world's animals in Biblical times and that the exact same animals existed 5, years ago as do today. Did we mention that they also had no conception of deep geologic time?

Real mosasaurus

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.

Everhart Bell's study served as a precedent for later studies that mostly left the systematics of Mosasaurus unchanged, [7] [9] although some later studies have recovered the sister group to Mosasaurus and Plotosaurus to instead be Eremiasaurus or Plesiotylosaurus depending on the method of data interpretation used, [70] [71] [74] with at least one study also recovering M. Isolated bones suggest some M.

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.
