Thalattoarchon

名字的意思： “sea ruler lizard eater”1

吃：肉魚龍類三疊紀中期嚴格來說不是恐龍

Thalattoarchon was a giant marine reptile that lived in the sea, not a dinosaur. It was one of the first big predators in the ocean after a huge extinction, and it ate other large 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。

趣味知識

Thalattoarchon lived about 244 million years ago, just 8 million years after the worst mass extinction on Earth.1

Its name means 'sea ruler' and 'lizard eater' in Greek.1

Thalattoarchon had huge teeth that were flat from side to side with sharp cutting edges, like a knife.1

It was about as long as a killer whale, over 8.6 metres (28 feet).1

This predator was one of the first top hunters in the ocean after the Permian-Triassic extinction.1

Only one fossil of Thalattoarchon has been found, a partial skeleton including most of the skull and backbone.1

Its teeth were up to 12 centimetres (5 inches) tall, with a crown 5 centimetres (2 inches) high.1
