Hydrotherosaurus

Igama lithetha: “fisherman lizard”1

Yayitya: InyamaIiplesiosauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

Hydrotherosaurus was a long-necked marine reptile that swam in the seas near California about 70 million years ago. It used its tiny head and super long neck to sneak up on fish and snap them up.1

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

izinto ezimnandi

Iinyani ezimnandi

Hydrotherosaurus had one of the longest necks compared to its body of any elasmosaur, with 60 vertebrae in its neck.1

Its head was very small, only about 33 centimetres (13 inches) long.1

The first bones were found by Frank C. Paiva on his own property in California in 1937.1

A nearly complete skeleton was dug up and put on display at the Golden Gate International Exposition in San Francisco.1

It weighed about 1.9 metric tons (2.1 short tons), as heavy as a small car.1

Hydrotherosaurus lived in the Late Cretaceous period, between about 72 and 66 million years ago.1 2

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