Not only do the extinct pterosaurs show evidence that their bones that were invaded by air sacs, but patterns of pneumaticity throughout the entire skeleton of different pterosaur species parallel trends identified in many living bird groups.

Additionally, some neovenatorids survived until late into the Cretaceous, and some taxa (such as Fukuiraptor) are sleek, mid-sized animals that convergently share many features of the appendicular skeleton and the extent of postcranial pneumaticity with bird-like coelurosaurian theropods.
