Carsosaurus

名字的意思： “Karst lizard”1

吃：肉滄龍類白堊紀晚期嚴格來說不是恐龍

Carsosaurus was an ancient marine lizard that lived in the warm seas of what is now Slovenia. It had a long tail and could swim, but it also spent time on land. This reptile was an early relative of the huge mosasaurs that ruled the oceans later.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。

趣味知識

Carsosaurus is known from only one fossil, which is missing its skull and most of its tail.1

The fossil includes skin impressions that show rhombus-shaped scales with thickened edges.1

Scientists think Carsosaurus gave birth to live young, not eggs, because the fossil may contain embryos inside the mother.1

The preserved part of the skeleton is about 97.5 centimetres (3 feet 2 inches) long, but the whole animal may have been 1.3 to 1.4 metres (4.3 to 4.6 feet) long.1

Carsosaurus lived during the Late Cretaceous, about 100 to 94 million years ago.1 4

Its long tail may have been used as a rudder for swimming, for defense, or for grasping.1

Carsosaurus is part of the mosasaur superfamily, but it was more land-dwelling than its fully aquatic later relatives.1

關於 Carsosaurus 最常被問的問題

?Was Carsosaurus a dinosaur?

No, Carsosaurus was not a dinosaur. It was a marine lizard in the mosasaur superfamily, more closely related to modern monitor lizards.1

?How big was Carsosaurus?

The preserved part of the skeleton is about 97.5 centimetres (38.4 inches) long, but the whole animal may have been 1.3 to 1.4 metres (4.3 to 4.6 feet) long.1

?Did Carsosaurus give birth to live young?

Yes, scientists think Carsosaurus gave birth to live young. The fossil may contain embryos inside the mother, and they would have been born tail-first to avoid drowning.1 3

迷思破解王

迷思： Carsosaurus was a dinosaur.

真相： Carsosaurus was a marine lizard, not a dinosaur. It belongs to the mosasaur group, which are reptiles but not dinosaurs.1

國家: 斯洛維尼亞4
化石紀錄: The Paleobiology Database 收錄 1 筆4
發現: Carsosaurus was named by Austrian paleontologist Andreas Kornhuber in 1893. He described a single fossil from the Karst Plateau near Komen, Slovenia, which was kept at the Museo Civico di Storia Naturale di Trieste.1 2
仍有爭議: Scientists are not sure if Carsosaurus is really a separate genus or if it should be called Aigialosaurus, because the skull is missing.1
