Eoplesiosaurus

Igama lithetha: “dawn Plesiosaurus”1

Yayitya: InyamaIiplesiosauriiJurassic yokuqalaNgokwenene ayisiyo dayinaso

Eoplesiosaurus was one of the very first plesiosaurs, swimming in the seas just after the Triassic-Jurassic extinction. It had a very long neck and four flippers, and it used them to paddle through the water and catch fish.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

Eoplesiosaurus is one of the oldest plesiosaurs ever found, living about 199 to 198 million years ago.1

Its neck was very long, with at least 38 neck bones, and its neck was longer than its body.1 2

The only fossil of Eoplesiosaurus is a complete skeleton from the neck down, found in the Blue Lias Formation in England.1

Eoplesiosaurus had small, cone-shaped bumps on the bases of its neck bones, which is a unique feature not seen in other plesiosaurs.1 2

It lived right after the Triassic-Jurassic extinction event, when many ocean animals died out and plesiosaurs began to take over the seas.2

Eoplesiosaurus was a small plesiosaur, with a body length of only about 2 to 3 metres (6.5 to 10 feet).2

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

Ukuhlelwa: Plesiosauria > Sauropterygia3
Ubudala bamatye: 201 ukuya ku-200 izigidi zeminyaka (Hettangian)3

Ukufunyanwa: Eoplesiosaurus was named in 2012 by Roger Benson, Mark Evans and Patrick Druckenmiller. The only skeleton was found at Watchet in Somerset, England, in rocks from the earliest Jurassic.1 3
Kusaxoxwa ngayo: Scientists are not sure exactly how big Eoplesiosaurus grew, because only one skeleton has been found.1
