Guanlingsaurus

名字的意思： “Guanling lizard, after Guanling County in China where it was found”1

吃：肉魚龍類三疊紀晚期嚴格來說不是恐龍

Guanlingsaurus was a giant marine reptile that lived in the Late Triassic, about 235 to 227 million years ago. It had a very short, toothless snout and sucked in fish and squid like a vacuum cleaner. It could grow as long as a school bus!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

Guanlingsaurus had a very short, toothless snout, which is very different from most other ichthyosaurs that had long jaws full of teeth.1

Its skull was tiny compared to its body, making up only about 8 to 9 percent of its total length.1

It had an extremely high number of vertebrae: 86 in the neck and trunk and more than 110 in the tail.2

Guanlingsaurus lived during the Carnian age of the Late Triassic, about 235 to 227 million years ago.3

A complete juvenile skeleton was found in 2013, which helped scientists confirm that Guanlingsaurus was a distinct genus from Shastasaurus.1

關於 Guanlingsaurus 最常被問的問題

?Was Guanlingsaurus a dinosaur?

No. Guanlingsaurus was an ichthyosaur, a marine reptile that lived in the sea, not a dinosaur.1

?How did Guanlingsaurus feed?

It likely sucked in fish and squid like a vacuum cleaner, but some scientists think its hyoid bones were too weak for strong suction feeding.4 5

?Where was Guanlingsaurus found?

In Guanling County, Guizhou Province, China, in rocks from the Late Triassic.1

?How long was the juvenile Guanlingsaurus?

About 3.74 metres (12.3 feet) long.1

迷思破解王

迷思： Many people think Guanlingsaurus had teeth like other ichthyosaurs.

真相： Guanlingsaurus was completely toothless, even as a juvenile, and had no dental groove in its jaws.1

類群: 魚龍類
科 / 演化支: Shastasauridae6

發現: Guanlingsaurus was first named in 2000 by Yin and colleagues based on an incomplete adult skeleton from Guanling County, China. More complete skeletons, including a juvenile, were described in 2011 and 2013.1
仍有爭議: Scientists still debate whether Guanlingsaurus should be its own genus or a species of Shastasaurus. It was moved to Shastasaurus in 2011 but later reinstated as a separate genus in 2013.1
