Tatenectes

Igama lithetha: “Tate diver, honoring Marion and Inez Tate who founded the Tate Museum in Casper, Wyoming”1
Yayitya: InyamaIiplesiosauriiJurassic yamvaNgokwenene ayisiyo dayinaso

Tatenectes was a small plesiosaur that lived in a shallow sea that covered much of North America during the Jurassic Period. It had a flattened, boxy body and a long neck, and it swam using four flippers like paddles.1

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

izinto ezimnandi

Iinyani ezimnandi

1

Tatenectes had a very unusual body shape for a plesiosaur: its torso was flattened and boxy, and its belly ribs were thickened, which helped it stay stable in turbulent water.1

2

The first fossil of Tatenectes was described in 1900 by Wilbur Clinton Knight, who thought it was a species of Cimoliosaurus. That original specimen has since been lost.1

3

Tatenectes lived in the Sundance Sea, a shallow inland sea that was less than 40 meters (130 feet) deep and covered parts of western North America during the Jurassic.1

4

Its teeth were small and thin, with long roots and low enamel ridges, perfect for catching slippery prey like fish and squid.1

5

Tatenectes shared its sea home with other marine reptiles, including the plesiosaur Pantosaurus and the large pliosaur Megalneusaurus.1

6

Scientists think Tatenectes could have used lung deflation to help it dive, just like some modern sea turtles do.1

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

Ukufunyanwa
The first fossil was described by Wilbur Clinton Knight in 1900 as a new species of Cimoliosaurus. In 2003, F. Robin O'Keefe and William Wahl Jr. gave it its own genus, Tatenectes, based on a new specimen found in Wyoming.12
Kusaxoxwa ngayo
Scientists are still debating whether the gastroliths (stomach stones) found in plesiosaurs like Tatenectes were used for ballast, digestion, or something else.1
