酷東西

趣味知識

Guidraco had 82 teeth in its head, with the front ones being very long and sticking out far beyond the beak.1

The first tooth in the upper jaw pointed almost straight forward, like a spear.1

Guidraco lived about 120 million years ago during the Early Cretaceous period.1

Its neck vertebrae had large holes that let air sacs enter the bones, making them lighter for flight.1

Guidraco is closely related to Ludodactylus, a pterosaur from Brazil, showing that pterosaurs moved between continents.1

The only fossil found so far is a partial skeleton including a nearly complete skull and neck bones.1
