tooth marks

Martin is a geologist and paleontologist focused primarily on ichnology -- the study of traces of life such as tracks, burrows, nests and tooth marks.

The scientists found little evidence of tooth marks on the dinosaur’s skeleton beyond the ribs Repenomamus had clamped down on.

The remains of 11 individuals who lived some 800,000 years ago displayed distinctive signs of having been eaten, with bones displaying cuts, fractures where they had been cracked open to expose the marrow and human tooth marks.

The shells lacked telltale signs of being eaten by other animals, like tooth marks or shattering patterns from being dropped on rocks by birds.

The formulation is simple for Friedman: Those are tooth marks, and who else would have bit the piano?
