Tooth marks on fossil bones from the late Jurassic period 150million years ago give “excellent evidence of feeding habits”.

They found 684 specimens with at least one bite mark from a theropod, probably Allosaurus.
Most were on bones of plant-eating reptiles, but 17 per cent were on those of other theropods.
Observed bite marks include punctures, scores, furrows, pits, and striations.
Researcher Stephanie Drumheller said: “Big theropods were not picky eaters, especially if strapped for resources.

The US team from the University of Tennessee analysed 2,000 bone fragments from the Mygatt-Moore Quarry, Colorado.
