吃：肉魚龍類侏羅紀早期嚴格來說不是恐龍

Wahlisaurus was a dolphin-like marine reptile that swam in the seas of Early Jurassic England. It had a very long, slender snout and an overbite, like a swordfish. It was not a dinosaur, but a type of ichthyosaur.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。

酷東西

趣味知識

Wahlisaurus had a very unusual shoulder bone called a coracoid, which had a large hole in it. This hole is rarely seen in ichthyosaurs.2

The first Wahlisaurus fossil was discovered by a man named Percy Faulkes, who donated it to a museum when he died in 1951.1

Wahlisaurus is named after two scientists: William Wahl and Judy Massare, who both studied ancient marine reptiles.1

Only two specimens of Wahlisaurus have ever been found. The second one was discovered in 1996 but not identified until 2018.1

Wahlisaurus lived during the Hettangian age, about 201 to 199 million years ago, right after a big extinction event.3

Its snout was extremely slender and delicate, and its lower jaw was shorter than its upper jaw, giving it an overbite.2

發現: Wahlisaurus was named and described by paleontologist Dean Lomax in 2016. The first fossil, a partial skull and skeleton, was found in Nottinghamshire, England, and had been sitting in a museum collection since 1951.1 2
仍有爭議: Scientists are not sure exactly how big Wahlisaurus grew, because only incomplete skeletons have been found.1
