Eurhinosaurus

名字的意思： “well-nosed lizard”1

吃：肉魚龍類侏羅紀早期嚴格來說不是恐龍

Eurhinosaurus was a fast-swimming marine reptile that looked a bit like a dolphin with a swordfish snout. It lived in the warm seas of the Early Jurassic, about 183 to 175 million years ago, and used its long, toothy upper jaw to stab small fish and squid.1 2

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

Eurhinosaurus had a huge overbite: its upper jaw was much longer than its lower jaw, like a swordfish.1

It belonged to a group called leptonectid ichthyosaurs, which were fast and had long, slender snouts.2

The first Eurhinosaurus fossil from Switzerland was found in 1981 by a woman named Carol Spörli in a clay pit near Staffelegg.2

Eurhinosaurus lived during the Toarcian age of the Early Jurassic, about 183 to 175 million years ago.1

Scientists think Eurhinosaurus used its long, toothy upper jaw like a spear to injure or stab small, soft prey.1

Eurhinosaurus was one of the most widespread ichthyosaurs of its time, found across many parts of Western Europe.2
