名字的意思： “Himalayan lizard”1

吃：肉魚龍類三疊紀晚期嚴格來說不是恐龍

Himalayasaurus was a giant marine reptile that swam in the warm seas of the Late Triassic, about 215 million years ago. It was not a dinosaur, but a type of ichthyosaur, with a long body, flippers, and a fish-like tail. It was a fierce predator that hunted other sea creatures.1

趣味小知識：這種海生爬蟲類在海裡游泳的時候，恐龍正在陸地上走路。大家都叫牠們恐龍，但牠們其實是爬蟲類的另一個分支。

酷東西

趣味知識

Himalayasaurus could grow over 15 metres (49 feet) long, which is longer than a school bus.1

Its teeth had special cutting edges, a feature not seen in most other ichthyosaurs, which helped it slice through prey.1

It lived in the ocean, not on land, and likely swam using its powerful flippers and tail.1

Himalayasaurus is known from only a few bones, including teeth, limb bones, and vertebrae, found in Tibet.1

It belonged to a group called Shastasauridae, which included other giant ichthyosaurs like Shonisaurus.1
