Dinosaur fossil: Even specialized predators didn't turn down free meals
Date:3/6/2012

Scientists have discovered a bone from a pterosaur (giant flying reptile or 'pterodactyl') in the guts of the skeletal remains of a Velociraptor (small predatory theropod dinosaur) that lived in the Gobi Desert in Mongolia some 75 million years ago.

The findings published online in Palaeogeography, Palaeoclimatology, and Palaeoecology, support the idea that Velociraptor, a carnivore with a specialised sickle shaped slashing talon on the second toe of each foot and large grasping hands, would also scavenge on available carcasses rather than turn down a free meal.

They also indicate that small non-avian dinosaurs were capable of consuming relatively large bones, something that we see in modern crocodiles.

The international research team involved scientists from University College Dublin, Ireland; the National Museum of Nature and Science, Tokyo, Japan; the Museum of Natural Sciences, Okayama, Japan; and the Mongolian Academy of Sciences, Ulaanbaatr, Mongolia.

"It would be difficult and probably even dangerous for the small theropod dinosaur to target a pterosaur with a wingspan of 2 metres or more, unless the pterosaur was already ill or injured," says Dr David Hone, one of the co-authors of the study, who was based at the UCD School of Biology and Environmental Sciences, University College Dublin, Ireland, at the time of the analysis.

"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."

The fossil, originally recovered from the Gobi Desert in 1994, shows the well preserved 75 mm long pterosaur bone lodged in the upper part of the Velociraptor ribcage where its stomach would have been.

"The surface of the bone is smooth and in good condition, with no unusual traces of marks or deformation that could be attributed to digestive acids," says Dr Hone.
