Edgarosaurus

Igama lithetha: “Edgar's lizard”3

Yayitya: InyamaIiplesiosauriiCretaceous yokuqala ukuya ku-iCretaceous yamvaNgokwenene ayisiyo dayinaso

Edgarosaurus was a short-necked plesiosaur that swam in the warm, shallow sea that once covered Montana. It used its long snout and sharp teeth to catch fish and other slippery prey.1 2

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Edgarosaurus had a short neck and a long snout, unlike the long-necked plesiosaurs like Elasmosaurus.1

Its skull is one of the oldest and best-preserved plesiosaur skulls from the Cretaceous of North America.1

Edgarosaurus had 26 neck bones, which is more than some other short-necked plesiosaurs like Dolichorhynchops (which had 19).2

It had a small opening in the top of its skull called a pineal foramen, which some other plesiosaurs lacked.2

The only known fossil of Edgarosaurus was found in the Thermopolis Shale, which was once the bottom of the Western Interior Seaway.1

Edgarosaurus lived about 106 to 94 million years ago, during the Late Cretaceous period.2

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

Kwiingcali zeedayinaso

Igama lenzululwazi: Edgarosaurus
Inikwe igama ngu:: Druckenmiller 20023
Iqela: Iiplesiosauri
Usapho / iclade: Polycotylidae3
Ukuhlelwa: Plesiosauria > Sauropterygia3
Ubudala bamatye: 106 ukuya ku-94 izigidi zeminyaka (Albian / Cenomanian)3
Izakhiwo zamatye: Thermopolis Shale3
Amazwe: iUSA3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Edgarosaurus was named by Pat S. Druckenmiller in 2002, based on a partial skeleton found in Montana. The type specimen includes a complete skull, many vertebrae, and a forelimb.1 3
Kusaxoxwa ngayo: Scientists are not sure exactly how Edgarosaurus is related to other plesiosaurs. Some place it in the group Polycotylidae, but its exact family tree is still debated.1
