EDMONTON — A rare fossil revealing a dinosaur’s last meal is shedding new light on ancient ecosystems and behaviours. 

University of Alberta paleontologist Corwin Sullivan says the fossil of a crow-sized, birdlike dinosaur he describes in a new paper has a mammal’s foot in its belly. 

Microraptor Zhaoianus lived about 120 million years ago and is known to have eaten fish and other lizards.

But this is one of only a few fossils that show the dinosaur preyed on the small mammals of the time as well.
