名字的意思： “wonder reptile”1

吃：肉蛇頸龍類侏羅紀中期嚴格來說不是恐龍

Thaumatosaurus was a plesiosaur, a long-necked marine reptile that lived in the sea. It swam in warm, shallow waters during the Jurassic Period, about 168 to 165 million years ago. Scientists are not sure exactly what it looked like because the fossils are very incomplete.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

Thaumatosaurus was named in 1841 by the paleontologist Christian Erich Hermann von Meyer.1

The name Thaumatosaurus means 'wonder reptile' in Greek.1

Many fossils that were once called Thaumatosaurus are now thought to belong to other plesiosaurs like Rhomaleosaurus and Meyerasaurus.1

Thaumatosaurus is considered a 'nomen dubium' or doubtful name, because the original fossil pieces are too few to tell exactly what kind of plesiosaur it was.1

The fossils of Thaumatosaurus were found in rocks from the Bathonian stage, which is about 168 to 165 million years old.2

Thaumatosaurus lived in the ocean and was a strong swimmer, using its flippers to move through the water.2

迷思破解王

迷思： Some people think Thaumatosaurus was a dinosaur.

真相： Thaumatosaurus was a plesiosaur, a marine reptile that lived in the sea, not a dinosaur. Dinosaurs lived on land.1

發現: Thaumatosaurus was named in 1841 by the German paleontologist Christian Erich Hermann von Meyer. He described the species Thaumatosaurus oolithicus from partial skull, backbone and limb fossils found in Germany.1
仍有爭議: Scientists are not sure what Thaumatosaurus really looked like because the original fossils are too incomplete. It might be the same as another plesiosaur.1
