Gulosaurus

名字的意思： “Helm's wolverine lizard”1

吃：肉魚龍類三疊紀早期嚴格來說不是恐龍

Gulosaurus was an early ichthyosaur, a marine reptile that lived in the ocean during the Early Triassic. It looked a bit like a dolphin and swam by paddling with its flippers. It was about 1.5 meters long, as long as a bicycle.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。

酷東西

趣味知識

Gulosaurus had five fingers on each flipper, like a human hand, instead of many extra finger bones that later ichthyosaurs had.1

Its name honors the Wolverine Nordic and Mountain Society and Dr. Charles Helm, who helped find fossils near Wapiti Lake.1

Scientists first thought Gulosaurus was either Grippia or Parvinatator, but a skull found in 2013 showed it was a new species.1

Gulosaurus lived about 250 to 248 million years ago, soon after the biggest mass extinction on Earth.2

Its skull had a notch on the first metacarpal bone in the flipper, which was different from its close relative Grippia.1

給恐龍專家

學名: Gulosaurus
命名者: Cuthbertson et al. 20133
類群: 魚龍類
科 / 演化支: Grippidia3
分類: Ichthyosauromorpha3
岩石的年代: 251 到 249 百萬年 ()3
岩層: Sulphur Mountain3
國家: 加拿大3
化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Gulosaurus was named by Robin Cuthbertson, Anthony Russell, and Jason Anderson in 2013. The first fossil was incomplete, but a second half with the skull was found later and showed it was a new species.1
仍有爭議: Scientists are not sure what the front teeth of Grippia looked like, so they cannot be certain how Gulosaurus's teeth compared.1
