Stenorhynchosaurus

名字的意思： “narrow snout lizard”1

吃：肉蛇頸龍類白堊紀早期嚴格來說不是恐龍

Stenorhynchosaurus was a pliosaur, a type of short-necked plesiosaur that swam in the warm seas of what is now Colombia. It was a fierce hunter with a long, narrow snout full of sharp teeth. This marine reptile lived about 126 million years ago, during the Early Cretaceous.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

The first fossils of Stenorhynchosaurus were discovered in 2000 by a farmer named Jorge Muñoz, who reported them to local authorities.1

The nearly complete skeleton was dug up between 2004 and 2005 and is now kept in Bogotá, Colombia.1

Stenorhynchosaurus was originally thought to be a species of Brachauchenius, a pliosaur from the United States, but later studies showed it was a new genus.1

Its name means 'narrow snout lizard' because of its long, slender jaws.1

This pliosaur lived in a shallow, intertidal marine environment, as shown by the claystone rocks where it was found.1

An ammonite fossil was found inside the skull of Stenorhynchosaurus, possibly part of its last meal.1
