Yayitya: InyamaIimosasauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

Plesiotylosaurus was a giant marine lizard that swam in the warm seas of the Late Cretaceous. It was not a dinosaur, but a fierce predator with a long, powerful body and a skull full of sharp teeth.1

izinto ezimnandi

Iinyani ezimnandi

Plesiotylosaurus had a bony rostrum (a kind of snout tip) that stuck out in front of its teeth, which is unusual among mosasaurs.1

Its lower jaw alone was nearly 1 meter (3.2 feet) long, about the height of a 3-year-old child.1

Plesiotylosaurus had teeth on the roof of its mouth (pterygoid teeth) that were almost as big as its regular teeth.1

Even though its name means 'near Tylosaurus', Plesiotylosaurus is not closely related to Tylosaurus. They just evolved similar skull features separately.1

The holotype skull of Plesiotylosaurus was found in the Panoche Hills of California, and it is a bit squashed but still mostly complete.1

Plesiotylosaurus lived about 70 to 66 million years ago, right at the end of the Age of Dinosaurs.1

Umfanekiso owenziwe yi-AI: Plesiotylosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Plesiotylosaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Plesiotylosaurus

?How big was Plesiotylosaurus?

About 6 metres (20 feet) long, based on its 98 cm (3.22 feet) lower jaw. Some estimates suggest around 6.5 metres.1 2

?What did Plesiotylosaurus eat?

It was a carnivore and probably ate tough prey like marine turtles, which are found in the same rocks. Its robust skull and strong jaws suggest it could handle hard-shelled animals.1 2

?Was Plesiotylosaurus a dinosaur?

No, it was a marine lizard belonging to the mosasaur family, not a dinosaur. It swam in the sea during the Late Cretaceous.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Plesiotylosaurus
Inikwe igama ngu:: Camp 19423
Iqela: Iimosasauri
Usapho / iclade: Mosasauridae3
Ukuhlelwa: Mosasauroidea3
Ubudala bamatye: 72 ukuya ku-66 izigidi zeminyaka (Maastrichtian)3
Izakhiwo zamatye: Moreno3
Amazwe: iUSA3
Iirekhodi zeefosili: 2 kwi-Paleobiology Database3
Ukufunyanwa: Plesiotylosaurus was named by C. L. Camp in 1942 based on a skull and jaws found in the Moreno Formation of California.1 3
Kusaxoxwa ngayo: Scientists still debate whether Plesiotylosaurus should be considered a separate genus or if it is actually a species of Prognathodon, because their skulls are so similar.1
