Bite marks suggest raptors or a young Albertosaurus fed on a dead relative

Researchers found bite marks on the jaw of a young Albertosaurus fossil.

The lack of healing suggests the animal was bitten around the time it died.

Smaller raptors may have scavenged its body, but a baby Albertosaurus could also have eaten it.

If so, the fossil would provide rare evidence of cannibalism among dinosaurs.
