Megalneusaurus

Igama lithetha: “king of large swimming lizards”1

Yayitya: InyamaIiplesiosauriiJurassic yamvaNgokwenene ayisiyo dayinaso

Megalneusaurus was a giant marine reptile that swam in the shallow Sundance Sea during the Late Jurassic. It was one of the biggest predators in North America at that time, with four flippers and a big head.1

izinto ezimnandi

Iinyani ezimnandi

Megalneusaurus was one of the largest pliosaurs in North America, measuring about 7 to 9 meters (23 to 30 feet) long.1

Its back flippers were bigger than its front flippers, which is unusual for plesiosaurs.1

Fossil stomach contents include tiny hooks from squid-like animals and bits of fish bones.1 2

It lived in the Sundance Sea, a shallow sea that covered parts of North America during the Jurassic.1

Scientists think it was an ambush predator, waiting to surprise its prey.1

A specimen from Alaska suggests it could also live in colder waters.1

Umfanekiso owenziwe yi-AI: Megalneusaurus — Umfanekiso owenziwe yi-AI obonisa indlela Megalneusaurus 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: Megalneusaurus

?How big was Megalneusaurus?

Megalneusaurus was about 7 to 9 meters (23 to 30 feet) long. Some estimates say it could reach around 13 meters (43 feet).1

?What did Megalneusaurus eat?

It ate squid-like animals and fish, based on hooklets and fish bones found in its stomach. It may also have eaten other plesiosaurs.1 2

?Could Megalneusaurus live in cold water?

Yes. A specimen found in Alaska shows it could live in colder waters, where there were fewer animals.1

?Was Megalneusaurus a dinosaur?

No, it was a marine reptile called a pliosaur, not a dinosaur. It lived in the sea.1

Inyaniso ngeentsomi

Intsomi: Some people think Megalneusaurus was a dinosaur.

Inyaniso: It was a plesiosaur, a marine reptile, not a dinosaur.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Megalneusaurus
Inikwe igama ngu:: Knight 18983
Iqela: Iiplesiosauri
Usapho / iclade: Plesiosauria3
Ukuhlelwa: Plesiosauria > Sauropterygia3
Ubudala bamatye: 162 ukuya ku-155 izigidi zeminyaka (Oxfordian)3
Izakhiwo zamatye: Sundance3
Amazwe: iUSA3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Wilbur Clinton Knight found and described the first fossils in 1895, near Ervay, Wyoming. He first called it Cimoliosaurus rex, then gave it its own genus name in 1898.1 2
Kusaxoxwa ngayo: Scientists debate whether Megalneusaurus is a valid genus because many of the original fossils were lost.1
