Dinosaurs swallowed prey whole and spat out their bones

Date:



Dinosaurs swallowed their prey whole and spat out their bones, scientists have found.

Newly discovered fossils suggest giant flying Pterosaurs had two ­stomachs — one for digesting food and the other for collecting inedible bones and scales.

It means their bigger land-based cousins, such as the mighty T-Rex, probably did the same.

Dr. Shunxing Jiang, of Beijing’s Chinese Academy of Sciences, explained: “The two-part stomach could have evolved early on, adding credence to the hypothesis that it was common to all dinosaurs.”

Modern birds all have two stomachs and some, such as the owl, still swallow food whole and regurgitate the bones.

Pterosaurs first emerged 250 million years ago before going extinct with the rest of the dinosaurs 65 million years ago.
