T. rex cousin has battle scars and signs of cannibalism

The skull of an adolescent tyrannosaur shows signs of vicious combat and of being eaten by other big dinosaurs, possibly of the same species. The 500kg animal was a Daspletosaurus, a slightly smaller cousin of the mighty T. rex - which has already faced scientific accusations of cannibalism. This unfortunate specimen received many vicious wounds while alive, and was then bitten by a scavenger after death. Results of the crowd-funded study were reported in open-access journal PeerJ. "This animal clearly had a tough life, suffering numerous injuries across the head including some that must have been quite nasty," said lead author Dr David Hone from Queen Mary, University of London. "The most likely candidate to have done this is another member of the same species, suggesting some serious fights between these animals during their lives." The beast was probably about six metres long and its remains were found in a quarry in Alberta, Canada, in 1994. Its skull, housed in Alberta's Royal Tyrrell Museum, shows many injuries which Dr Hone and his colleague Darren Tanke, a senior technician at the museum, have now described in detail.READ MORE-http://www.bbc.co.uk/news/science-environment-32233105
