Qianichthyosaurus

名字的意思： “Qian ichthyosaur, named after the Qian region of China”1

吃：肉魚龍類三疊紀中期到三疊紀晚期嚴格來說不是恐龍

Qianichthyosaurus was a small, fast-swimming marine reptile that lived in the seas of ancient China. It looked a bit like a dolphin, with a long snout, big eyes, and flippers for paddling. Even though it was not a dinosaur, it ruled the ocean during the Triassic Period.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

Qianichthyosaurus had hind flippers that were almost as long as its front flippers, which helped it steer and swim quickly.1

Complete fossils of Qianichthyosaurus are common in the Xiaowa Formation, including both babies and pregnant females.1

The larger ichthyosaurs Guizhouichthyosaurus and Guanlingsaurus lived at the same time but are rarer than Qianichthyosaurus.1

Qianichthyosaurus is closely related to Toretocnemus, an ichthyosaur found in California, USA.1

The two species of Qianichthyosaurus lived at different times: Q. xingyiensis is older (Ladinian) and Q. zhoui is younger (Carnian).3

Qianichthyosaurus had a very short snout compared to many other ichthyosaurs, and its eyes were huge and round.2

關於 Qianichthyosaurus 最常被問的問題

?How big was Qianichthyosaurus?

Qianichthyosaurus was a small ichthyosaur. Q. zhoui measured 1.5 to 2 m (4.9 to 6.6 ft) long, while Q. xingyiensis was smaller at 1.3 m (4.3 ft) long.1

?What did Qianichthyosaurus eat?

It had small teeth, so it probably ate small fish and squid. Its relatives, like Shastasaurus, were suction feeders that ate soft prey.1 4

?Is Qianichthyosaurus a dinosaur?

No, it is not a dinosaur. It was an ichthyosaur, a marine reptile that lived in the ocean during the Triassic Period.1

?When did Qianichthyosaurus live?

It lived during the Middle to Late Triassic Period, about 237 to 227 million years ago.1

迷思破解王

迷思： Some people think Qianichthyosaurus was a dinosaur because it lived in the water and had flippers.

真相： Qianichthyosaurus was an ichthyosaur, a marine reptile that is not a dinosaur. Ichthyosaurs are a different group of reptiles that lived in the ocean.1
