吃：肉蛇頸龍類侏羅紀早期嚴格來說不是恐龍

Plesiopharos was an early plesiosaur that swam in the warm seas of Portugal about 195 million years ago. It had a long body, four flippers, and a short tail, and it used its sharp teeth to catch fish and other sea creatures.3 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

Plesiopharos is one of the oldest and most complete plesiosaurs ever found in the Iberian Peninsula, which includes Portugal and Spain.1

Its name comes from the Greek words for 'near' and 'lighthouse', because it was discovered near a lighthouse called Penedo da Saudade.1

The fossil was found by two fossil hunters, Vitor Teixeira and António Silva, who donated it to the Museu da Lourinhã in 2017.1

Plesiopharos lived during the Sinemurian age of the Early Jurassic, about 199 to 193 million years ago, when the Atlantic Ocean was just beginning to form.3 1

Scientists think Plesiopharos was a very early member of the group Plesiosauroidea, which includes the long-necked plesiosaurs that came later.1

The only known skeleton of Plesiopharos includes 22 vertebrae, ribs, parts of the hips and shoulders, and bones from its flippers.1

類群: 蛇頸龍類
科 / 演化支: Plesiosauroidea3
分類: Plesiosauria > Sauropterygia3
岩石的年代: 200 到 193 百萬年 (Sinemurian)3
國家: 葡萄牙3
化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Plesiopharos was named in 2021 by a team of scientists led by Eduardo Puértolas-Pascual. The fossil was found at Praia da Concha in Portugal and donated to the Museu da Lourinhã.3 1
仍有爭議: Scientists are not sure whether Plesiopharos belongs more closely to the long-necked plesiosauroids or to other early plesiosaur groups, because its skeleton has a mix of features from different lineages.1
