The rest of the pterosaur bones, found in the intestines Velociraptor

Scientists have discovered the bones of pterosaurs (flying reptiles that can be huge) in the skeletal remains of Velociraptor (or predatory theropod dinosaurs) that lived in the Gobi desert in Mongolio approximately 75 million years ago.

The findings are published online in Palaeogeography, Palaeoclimatology, Palaeoecology, and it reveals the idea that the velociraptor that is a carnivore that has a crescent-shaped sharp nails on both feet and large hands, allegedly has a habit of scavenging carcasses rather than go down and hunt for prey.

It also suggests that non-avian dinosaurs little more capable of consuming large bones, like modern-day crocodiles.

International research team included scientists from University College Dublin, Ireland's National Museum of Nature, Museum of Natural Sciences of Japan, and the Mongolian Academy of Sciences of Mongolia.

"It would be difficult and even dangerous to a small theropod dinosaur that is to target prey that pterosaurs had a wingspan of 2 meters or more, except pterosaurs in sick or injured" said Dr David Hone, one of the researchers from University College Dublin.

"So, pterosaur bones that we identified in the gut of the Velociraptor, most likely occurs by eating carrion rather than an attempt to kill (kills predatory) or chase prey" he explained.

The fossils were found from the Gobi desert in 1994 showed that the bone has a length of 75mm pterosaur nesting at the top of the rib Velociraptor.

"The surface of the bone was smooth and in good condition, without any changes. Thus, the possibility that the velociraptor died not long after swallowing bones" he concluded.

Further analysis of the skeletal remains of Velociraptor revealed that it died with extinct animals carrying an injury in his ribs.

Sources say, this is the first time that the bones of a pterosaur have been found in the intestines of the dinosaurs.
