Hauffiopteryx

名字的意思： “Hauff's wing”2

吃：肉魚龍類侏羅紀早期嚴格來說不是恐龍

Hauffiopteryx was a small, fast-swimming marine reptile that lived in the Early Jurassic seas. It looked a bit like a dolphin but was actually an ichthyosaur, a group of ocean-dwelling reptiles. With its long snout and big eyes, it was a skilled hunter of fish and squid.2 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

Hauffiopteryx had a very short snout compared to other ichthyosaurs, and its upper jaw stuck out a little bit past the lower jaw.1

Its belly ribs (gastralia) were extra long, reaching all the way to the 35th vertebra in its backbone, which is unique among ichthyosaurs from the same time.1

The holes on top of its skull (the temporal fenestrae) were small and round, unlike the larger openings in its relative Stenopterygius.1

Scientists think Hauffiopteryx might have had a special diet or hunting style because it only appears in rocks from a short time during the Early Jurassic, when the ocean had less oxygen.1

No one has ever found a baby Hauffiopteryx or any food remains inside its stomach, so how it grew and what it ate is still a mystery.1

Hauffiopteryx was first thought to be a type of Stenopterygius, but in 2008 scientists gave it its own genus because of its unique hip bones and other features.1

迷思破解王

迷思： Hauffiopteryx is a dinosaur.

真相： Hauffiopteryx is an ichthyosaur, a marine reptile that lived in the sea, not a dinosaur. Dinosaurs lived on land.2
