名字的意思： “Wiman's [reptile], named after Swedish paleontologist Carl Wiman”1

吃：肉魚龍類三疊紀中期嚴格來說不是恐龍

Wimanius was a small ichthyosaur, a marine reptile that swam in the sea during the Middle Triassic, about 247 to 237 million years ago. It had a big eye and teeth on the roof of its mouth, which is unusual for an ichthyosaur. It lived in a warm lagoon near what is now Switzerland.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

Wimanius had teeth on the roof of its mouth, which is very rare for an ichthyosaur. Scientists are not sure if those teeth were on the palatine or pterygoid bones.1

The only known fossil of Wimanius is a partial skull, about 25 centimeters long, found in the 1990s.1 2

Wimanius lived in a lagoon that was between 30 and 130 meters deep. The bottom of the lagoon had very little oxygen, but the surface waters were full of life.1

Wimanius shared its home with other ichthyosaurs like Mixosaurus and the much larger Besanosaurus, as well as many other marine reptiles.1

Scientists think Wimanius gave birth to live young, like other ichthyosaurs, instead of laying eggs.3

The name Wimanius honors Carl Wiman, a Swedish paleontologist who studied Triassic ichthyosaurs.1

Wimanius 的 AI 繪圖 — 這是電腦根據科學家目前的知識，用 AI 畫出 Wimanius 可能的樣子。這只是猜測：真正的動物可能長得不一樣，也沒有人知道牠真正的顏色。

迷思破解王

迷思： Some people think Wimanius was a dinosaur because it lived in the sea and looked like a fish.

真相： Wimanius was an ichthyosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land and had different body features.1

發現: Wimanius was named by Michael Maisch and Andreas Matzke in 1998. They found the skull in a museum collection and realized it was a new genus.1
仍有爭議: Scientists are not sure where Wimanius belongs in the ichthyosaur family tree. Some think it is related to mixosaurids, others think it is a merriamosaur, and some even question if it is a valid genus at all.1
