吃：魚飛行爬蟲類三疊紀晚期嚴格來說不是恐龍

Preondactylus was a small flying reptile that soared over the lagoons of ancient Italy. It had short wings and a long tail, and it was one of the earliest pterosaurs ever to take to the skies.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

The first Preondactylus fossil was accidentally broken into pieces when it was being collected, and then the bone was washed away by water, leaving only an imprint in the rock.1

A second Preondactylus fossil was found inside what scientists think is the vomit of a fish that ate the pterosaur.1

Preondactylus had teeth with just one point, and they were so widely spaced that they did not touch each other, so there was no tooth wear.1

Its short wings are considered a primitive feature, but Preondactylus was still a fully capable flier.1

The fossil was found in a type of rock called dolomitic limestone, which is very hard and often preserves delicate bones.1

Some scientists think Preondactylus might be the most primitive pterosaur, but others are not so sure.1 2

迷思破解王

迷思： Preondactylus was a dinosaur.

真相： Preondactylus was a pterosaur, a flying reptile that is a close cousin of dinosaurs, but not a dinosaur itself.1
