吃：魚海生爬蟲類三疊紀中期嚴格來說不是恐龍

Augustasaurus was a marine reptile that lived in the ocean during the Middle Triassic, about 244 to 242 million years ago. It had a long neck, a small head, and fang-like teeth for catching fish and squid. It was an early relative of the famous plesiosaurs.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

Augustasaurus is the only sauropterygian (a group of marine reptiles) found in the Favret Formation in Nevada.1

Its name comes from the Augusta Mountains in Nevada, where its fossils were discovered.1

Augustasaurus had a skull with tall, blade-like upper temporal arches, similar to its relative Pistosaurus.1

The first fossil of Augustasaurus was found in 1993 and was partly destroyed by weathering before scientists could study it.1

Scientists think Augustasaurus is an ancestor of plesiosaurs, the long-necked marine reptiles that lived later.1

Augustasaurus lived in a warm, shallow sea that was home to many ichthyosaurs, including the large predator Thalattoarchon.1
