According to an article published by The Asahi Shimbun on September 22, a team of Japanese and Canadian scientists have discovered evidence of bone cancer in fossilized dinosaur remains. Scientists from Japan’s Okayama University of Science and Canada’s Royal Ontario Museum and McMaster University analyzed a leg bone of the herbivorous Centrosaurus apertus after discovering that the end of the bone was deformed.

“No such studies had been conducted [before] in which experts, including clinicians, have closely looked at fossilized dinosaur remains and diagnosed the disease using the same standards as for human diagnoses,” according to Kentaro Chiba, assistant professor of vertebrate palaeontology at Okayama University of Science.
