Brasileodactylus

名字的意思： “pterosaur (wing finger) from Brazil”1

吃：魚飛行爬蟲類白堊紀早期嚴格來說不是恐龍

Brasileodactylus was a flying reptile that soared over the warm seas of Early Cretaceous Brazil. It had a long pointed snout full of sharp, forward-pointing teeth, perfect for catching fish. Unlike many of its relatives, it had no crest on its snout or lower jaw.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

Brasileodactylus lived about 112 million years ago during the Early Cretaceous.1

Its wingspan was about 4 meters (13 feet), and it weighed around 10 kilograms (22 pounds).1

The first fossil found was just the front part of a lower jaw, discovered by paleontologist Alexander Kellner in 1984.1

Some scientists think Brasileodactylus might be the same animal as Cearadactylus, another pterosaur from the same time and place.1

It had no crest on its snout or lower jaw, but it might have had a small crest on the back of its skull.1

Brasileodactylus is known from several fossils, including a nearly complete skull and a partial skeleton.1
