Real mosasaurus

However, like all things relating to movie real mosasaurus 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.

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.

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. Most notably, the Wakayama Soryu had four large flippers shaped like paddles that helped it navigate underwater: two in the front and two in the rear. A medley of other features elevated this mosasaur beyond simple classification: a rudderlike tail, a crocodile-esque head, and the same dorsal fin found in certain whales made it an imposing predator. The plesiosaur, another prehistoric marine reptile, used its similarly shaped fins for propulsion, but it did not have the same type of tail as the Wakayama Soryu. According to a press release from the University of Cincinnati, researchers speculated that the front fins could have handled rapid maneuvering while the larger, rear fins were responsible for diving and surfacing. The tail, meanwhile, gave it the acceleration needed to easily catch prey. Which were for steering? Which for propulsion? The Wakayama Soryu has joined a pantheon of unique mosasaur species, some of which have also been unearthed and classified in recent years.

Such a trait is unique among squamates, the only known exception being the Argentine black and white teguwhich can maintain partial endothermy. Evans; Paul M. Tattersall; Cleo Real mosasaurus.

Mosasaurs refer to a group of large, carnivorous marine lizards that lived during the age of the dinosaurs, according to the Smithsonian. The video depicts a Mosasaurus — a large mosasaur that is thought to be related to whales and dolphins.

Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in They belong to the order Squamata , which includes lizards and snakes. During the last 20 million years of the Cretaceous period Turonian — Maastrichtian ages , with the extinction of the ichthyosaurs and pliosaurs , mosasaurids became the dominant marine predators. They themselves became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago. Mosasaurs breathed air, were powerful swimmers, and were well-adapted to living in the warm, shallow inland seas prevalent during the Late Cretaceous period. Mosasaurs were so well adapted to this environment that they most likely gave birth to live young , rather than returning to the shore to lay eggs as sea turtles do.

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 movie Mosasaurus also seems to have rows of osteoderms running down its back, similar to what we see in crocodiles, and overall its skin texture seems to have been largely inspired by crocodilians with the knobbed backs and shrink-wrapped heads. The genus adapted by accessing new habitats in more open waters. Clidastes propython. Globidens alabamaensis. The dentaries ahead of the fractures in both specimens are in good condition, suggesting that the arteries and trigeminal nerves had not been damaged; if they were, those areas would have necrotized due to lack of blood.

This level of bone infection would have been tremendously painful and severely hampered the mosasaur's ability to use its jaws. Gutstein

Mosasaurus facts and pictures.

Jagt; A. A study by Rothschild and Everhart surveyed 15 Mosasaurus specimens from North America and Belgium and found cases of fused tail vertebrae in three of them. Reconstructed skeleton of M. ISSN Terry Jr. The skull of Mosasaurus had robust jaws and strong muscles capable of powerful bites using dozens of large teeth adapted for cutting prey. ISSN X. In the film, the Mosasaurus is depicted with a flat, paddle-shaped tail bearing some sort of fin-like spines along it. From an ecological standpoint, Mosasaurus probably had a profound impact on the structuring of marine ecosystems; its arrival in some locations such as the Western Interior Seaway in North America coincides with a complete turnover of faunal assemblages and diversity.
