Mosasaurus (/ˌmoʊzəˈsɔːrəs/; "lizard of the Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic squamate reptiles. It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian stages of the Late Cretaceous.

Who found the first mosasaurus?

Many complete mosasaur specimens have been found in the Smoky Hill Chalk Member of the Niobrara Formation of Western Kansas, and some of the first mosasaur remains were collected by Professor Benjamin Mudge and Dr. George M. Sternberg more than 130 years ago.

Did mosasaurs lay eggs?

It is the second largest fossil egg ever found and may have belonged to a mosasaur, a 10-meter-long marine predator. Some snakes and lizards, living mosasaur relatives, lay eggs with thin shells that hatch almost as soon as they are laid. The new find suggests mosasaurs may have, too.

Are mosasaurs archosaurs?

Mosasaurs are not dinosaurs.

The term "dinosaur" is actually very specific and describes only the land-dwelling descendants of the "ruling reptiles", the archosaurs. Mosasaurs, on the other hand, are more closely related to modern-day lizards.

Why did mosasaurs go extinct?

During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators. They became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago.

What period did T Rex live in?

How long ago did Megalodon live?

The earliest megalodon fossils (Otodus megalodon, previously known as Carcharodon or Carcharocles megalodon) date to 20 million years ago. For the next 13 million years the enormous shark dominated the oceans until becoming extinct just 3.6 million years ago.

Did the mosasaurs have any predators?

Diet. were formidable predators that reached apex status after other oceanic hunters declined in population or became extinct. Mosasaurs would have been prey, as well. They were eaten by sharks, a detail established with the discovery of shark teeth fixed into mosasaur bone.

What did Mosasaurus eat?

Mosasaurs were huge animals, and they needed to eat in order to sustain their huge size. Paleontologists have discovered the preserved remains of mosasaur stomachs which contain food like fish, sharks, cephalopods, birds, and even other mosasaurs.

How did the mosasaur survive?

It is revealed that the individual Mosasaurus seen in Jurassic World has survived the months it has spent on Isla Nublar. ... The Mosasaurus then ate the sub, along with a mercenary trying to escape on a helicopter, and when the gates were left open, it escaped the lagoon and swam into the ocean.

Is the Megalodon still alive?

Megalodon is NOT alive today, it went extinct around 3.5 million years ago. Go to the Megalodon Shark Page to learn the real facts about the largest shark to ever live, including the actual research about it's extinction.

Did mosasaurs have forked tongues?

Ever since the first mosasaur restorations were published, these extinct marine reptiles have been pictured with either notched, forked or undivided tongues. ... We suggest that mosasaurs had a diploglossan tongue that remained in a relatively underived state.
