Mosasaurs were born at sea, not in safe harbors
Newly discovered fossils of prehistoric aquatic reptiles known as mosasaurs suggest that the creatures gave birth in midocean rather than in near-shore sanctuaries as previously suspected.

Curved claws hint at pterosaur habits
A study of the claws of flying reptiles known as pterosaurs suggests that some of the creatures may have walked like present-day herons and used their wing fingers to hold prey.
