Little is known about azhdarchid pterosaurs, gigantic flying reptiles with impressive wingspans of up to 12 meters. Cousins of dinosaurs and the largest animals ever to fly, they first appeared in the fossil record in the Late Triassic about 225 million years ago and disappeared again at the end of the Cretaceous period about 66 million years ago. One of their most notable features for such a large flighted animal was a neck longer than that of a giraffe. Now, researchers report an unexpected discovery in the journal iScience on April 14: their thin neck vertebrae got their strength from an intricate internal structure unlike anything that’s been seen before.
