PressTV - Large flying reptile’s skeleton found in Mongolia: "The 75mm-long pterosaur bone shard was found within the rib cage where the Velociraptor's gut would have been.
"It would be difficult and probably even dangerous for the small theropod dinosaur to target a pterosaur with a wingspan of 2 meters or more, unless the pterosaur was already ill or injured," said study co-author Dr. David Hone of the University College Dublin, Ireland.
"So the pterosaur bone we've identified in the gut of the Velociraptor was most likely scavenged from a carcass rather than the result of a predatory kill," he added.
Researchers say gut contents are rare and pterosaur bones are rather fragile and do not preserve well, so it is an unusual find. "
