Caupedactylus

名字的意思： “Caupe's finger, after the Tupi goddess of beauty”1

吃：植物飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Caupedactylus was a flying reptile with a big, thin crest on its head. It had no teeth and used its beak to eat fruit. It lived about 110 million years ago in what is now Brazil.1 3

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。

酷東西

趣味知識

Caupedactylus had a wingspan of about 3.3 metres (11 feet), making it the largest known tapejarine pterosaur.1

Its skull was about 46 centimetres long and had a large, rounded crest that was only half a millimetre thick at the top.1

The tip of its snout curved downward, and its upper jaw had a slightly concave lower edge.1

The crest on its snout had grooves that may have held blood vessels, possibly helping with temperature control.2

Its lower jaw had a thick, slightly convex surface at the rear, and when closed it fit tightly against the upper jaw with no gap.1

The holotype specimen (MN 4726-V) is an adult, which is rare for pterosaurs from this formation.1
