Rhamphocephalus

名字的意思： “beak head”1

吃：魚飛行爬蟲類侏羅紀中期到侏羅紀晚期嚴格來說不是恐龍

Rhamphocephalus was a flying reptile that lived during the Middle Jurassic. It soared over the warm seas of what is now England, snatching fish with its sharp beak. But scientists now think some of its bones actually belong to a different kind of reptile, a marine crocodylomorph!1

趣味小知識：翼龍在恐龍頭上飛來飛去，但牠們是恐龍的親戚，不是恐龍喔。

趣味知識

Rhamphocephalus was originally thought to be a pterosaur, but the type species, R. prestwichi, is now considered a thalattosuchian (a marine crocodylomorph).1

The name Rhamphocephalus was used as a 'wastebasket taxon' for many British Jurassic pterosaur remains, meaning it was a catch-all for fossils that didn't fit elsewhere.1

Fossils of Rhamphocephalus range from about 168 to 155 million years old, from the Bathonian to the Oxfordian stages of the Jurassic.2

Several species once placed in Rhamphocephalus, like Pterodactylus bucklandii, are now considered pterosaurs but not within this genus.1

The holotype (original specimen) of Rhamphocephalus prestwichi is just a fragment of skull roof, which made it hard for scientists to identify correctly.1

Rhamphocephalus 的 AI 繪圖 — 這是電腦根據科學家目前的知識，用 AI 畫出 Rhamphocephalus 可能的樣子。這只是猜測：真正的動物可能長得不一樣，也沒有人知道牠真正的顏色。

迷思破解王

迷思： Rhamphocephalus is definitely a pterosaur.

真相： The type species is actually a thalattosuchian (a marine crocodylomorph). The pterosaur species once grouped with it are now considered separate.1

給恐龍專家

學名: Rhamphocephalus
命名者: Seeley 18805
類群: 飛行爬蟲類
科 / 演化支: Rhamphorhynchidae5
分類: Pterosauria > Rhamphorhynchidae5
岩石的年代: 168 到 155 百萬年 (Bathonian / Oxfordian)5
岩層: Taynton Limestone, Cotswold Slate, Chipping Norton Limestone5
國家: 英國5
化石紀錄: The Paleobiology Database 收錄 10 筆5
又名: Dolichorhamphus （舊名稱現在也算作同一種動物）5
發現: Harry Seeley named Rhamphocephalus prestwichi in 1880 based on a skull roof fragment found by Professor Prestwich in Gloucestershire, England.1
仍有爭議: Scientists are still unsure which pterosaur species belong to Rhamphocephalus, because many of the fossils are incomplete or poorly preserved.1
