Analysis of juvenile daspletosaurus fossil bones showed partially healed bite marks indicating an attack by one of its own species.
There is no evidence, despite the wounds inflicted, that the daspletosaurus was killed by another tyrannosaurid, but another member of its family apparently ate it after its death.
Scientists have suspected that the member of the tyrannosaurid family was a cannibal for years but analysis of the fossil, first discovered in 1994 in Alberta, Canada is the first to show signs of both combat and cannibalism.
