Scanisaurus

名字的意思： “Skåne lizard”1

吃：肉蛇頸龍類白堊紀晚期嚴格來說不是恐龍

Scanisaurus was a long-necked marine reptile that swam in the shallow seas of what is now Sweden and Russia. It was about as long as a small car and used its sharp teeth to catch small fish and squid-like animals called belemnites.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

Scanisaurus is known from only a single backbone (a vertebral centrum) found in Russia, plus many similar backbones and teeth from Sweden.1

It lived about 80 to 75 million years ago during the Campanian stage of the Late Cretaceous.1

Scanisaurus had a shorter neck than some other elasmosaurids like Elasmosaurus, and scientists sometimes call it a 'mesodiran' plesiosaur.1

In the Kristianstad Basin, Scanisaurus fossils are the most common plesiosaur remains found.1

A fountain with two Scanisaurus sculptures was built in the Swedish town of Bromölla in 1971.1

Scanisaurus shared its home with many other marine reptiles, including mosasaurs, sea turtles, and crocodile-like animals.1

It ate small prey like small fish and belemnites (squid-like animals). Its sharp teeth were good for smashing or piercing them.1

?Is Scanisaurus a dinosaur?

No, it is not a dinosaur. It is a plesiosaur, a type of long-necked marine reptile that lived in the sea.1

類群: 蛇頸龍類
科 / 演化支: Elasmosauridae2
分類: Plesiosauria > Elasmosauridae > Sauropterygia2

發現: The first fossil, a single backbone, was named Cimoliasaurus nazarowi by Nikolay Bogolyubov in 1911 from Russia. In 1959, Swedish paleontologist Per-Ove Persson moved it to a new genus, Scanisaurus, based on fossils from Sweden.1
仍有爭議: Scientists debate whether Scanisaurus is a valid genus or a nomen dubium (doubtful name), because the fossils lack features that clearly separate it from other Late Cretaceous elasmosaurids.1
