Pterosaurs flew into the Late Cretaceous

Late Cretaceous skies might have been more crowded than previously thought. Until recently, scientists thought the dearth of pterosaur fossils found from the Late Cretaceous meant that the flying reptiles were in decline before the catastrophic end of the Mesozoic. But the recent discovery in Morocco of several new pterosaur species suggests this unique branch of reptiles may have been thriving just before the end-Cretaceous extinction.

Tiniest pterosaur found in British Columbia

Pterosaurs have a gargantuan reputation: Most fossils of the flying reptiles have wingspans similar to a small plane. But the recent discovery of fragmentary fossils from an eagle-sized specimen in British Columbia shows that not all pterosaurs were huge.

Tricky take-off limited pterosaur size

Pterosaurs are the largest flying animals in Earth’s history — some boasted nearly double the wingspan of the largest flying birds. But just how big the airborne reptiles grew and what kept them from achieving even greater sizes are outstanding questions. Now, a new study examining the mechanics of pterosaur flight suggests that taking off was perhaps the trickiest part of flying for pterosaurs, and likely constrained their size more so than other factors.
