Grippia

名字的意思： “Grippia means 'little griffin' or 'gripping one'.”1

吃：肉魚龍類三疊紀早期到三疊紀中期嚴格來說不是恐龍

Grippia was a small, dolphin-like marine reptile that lived in the Early Triassic seas. It swam by wiggling its tail like an eel and was one of the earliest ichthyosaurs.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

Grippia is one of the smallest ichthyosaurs, only about 1 to 1.5 metres long.1

The first complete skull of Grippia was found in 1929 but was destroyed during a bombing raid in World War II.1

Grippia swam by moving its tail side to side, just like a modern eel.1

It lived about 250 to 235 million years ago, during the Early to Middle Triassic.1

Grippia is considered the most basal (early) ichthyosaur, meaning it had a more primitive body than later species.1

No complete skeleton of Grippia has ever been found, only partial skulls and bones.1

關於 Grippia 最常被問的問題

?What did Grippia eat?

Scientists are not sure. Its teeth suggest it may have eaten both plants and animals (omnivore), or maybe molluscs and small fish. No one will know for certain until a full skull is found.1

?Where did Grippia live?

Grippia lived in shallow coastal seas during the Early Triassic. Its fossils have been found in Greenland, China, Japan, Norway, and Canada.1

?How did Grippia swim?

Grippia swam by moving its tail side to side, just like a modern eel.1

?Is Grippia a dinosaur?

No, Grippia is not a dinosaur. It is an ichthyosaur, a marine reptile that lived in the sea.1 2
