Bathyspondylus

名字的意思： “deep vertebra”1

吃：肉蛇頸龍類侏羅紀晚期嚴格來說不是恐龍

Bathyspondylus was a plesiosaur, a long-necked marine reptile that swam in the Jurassic seas. It is known from just a few bones found in England, so scientists are still figuring out what it looked like. Its name means 'deep vertebra' because its backbone bones were very deep from top to bottom.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。

趣味知識

Bathyspondylus is known only from a partial skeleton found in 1774, which includes 20 chest vertebrae, 23 back vertebrae, 1 tail vertebra, and some rib and hip bones.1

Its vertebrae are very short from front to back, and their ends are flat or slightly hollow.1

The fossils show a mix of features from two different plesiosaur groups, pliosauroids and plesiosauroids, which makes it hard to classify.1

The only known species is Bathyspondylus swindoniensis, named after the town of Swindon where it was found.1

Bathyspondylus lived during the Kimmeridgian stage of the Jurassic Period, about 155 to 150 million years ago.1

The holotype skeleton was once owned by William Cunnington III before 1810, and later ended up in the Devizes Museum in England.1
