Hauffiosaurus

名字的意思： “Hauff's lizard, after the Hauff family who ran the museum where the fossil is kept”1

吃：肉蛇頸龍類侏羅紀早期嚴格來說不是恐龍

Hauffiosaurus was a medium-sized plesiosaur that swam in the warm, shallow seas of the Early Jurassic. It had a very long, thin snout and slender teeth, perfect for catching slippery fish. Its fossils have been found in Germany and England.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

Hauffiosaurus zanoni is known from a nearly complete skeleton that was discovered in the early 1800s, but it was not properly described until 2001.1

The name Hauffiosaurus honors the Hauff family, who run the Urwelt-Museum Hauff in Holzmaden, Germany, where the type specimen is displayed.1

This plesiosaur had a very long, thin snout, a shape that scientists think is a sign it ate mostly fish.1

Its teeth were slender and had fine ridges running lengthwise, which helped it grip slippery fish.1

Three species are known: H. zanoni, H. tomistomimus, and H. longirostris. The last two were named in 2011.1

The largest species, H. tomistomimus and H. longirostris, grew to about 4.83 metres (15.8 feet) long.1

學名: Hauffiosaurus
命名者: O'Keefe 20013
類群: 蛇頸龍類
科 / 演化支: Pliosauridae3
分類: Plesiosauria > Pliosauridae > Sauropterygia3
岩石的年代: 184 到 175 百萬年 (Toarcian)3
岩層: Whitby Mudstone, Alum Shale, Posidonia Shale3
國家: 英國, 德國3
化石紀錄: The Paleobiology Database 收錄 4 筆3
發現: The first specimen of Hauffiosaurus was found in the early 1800s in Holzmaden, Germany, but it was not recognized as a new genus until Frank Robin O'Keefe named it in 2001. The type species is H. zanoni, named after Robert Thomas Zanon, who first realized it was something special.1
仍有爭議: Scientists are not sure exactly where Hauffiosaurus fits in the plesiosaur family tree. Some think it is a pliosauroid, but its exact position is still debated.1
