NEED TO KNOWResearchers say this is the first documented evidence of a raptor feeding on a tyrannosaurThe Albertosaurus was estimated to be 10 or 11 years old when it diedThe unhealed tooth marks suggest scavenging, though cannibalism remains a less likely explanationA small raptor may have taken a bite out of one of the most fearsome predators of its time. Researchers at the University of Alberta say tooth marks on the jaw of a young Albertosaurus, a relative of Tyrannosaurus rex, were most likely made by a dromaeosaurid, the group of small dinosaurs commonly known as raptors. Their study, published in the Journal of Paleontology, describes it as the first documented evidence of a raptor feeding on a tyrannosaur. Paleontologist Philip Currie, who supervised the research, said in a university announcement that the finding shows "a very small dinosaur eating a very big, mean, nasty dinosaur. "According to Earth.com, the Albertosaurus fossil first surfaced in 2022, when Peter Hodgkinson found broken skull bones at the base of a mudstone slope in the Red Deer River valley of Saskatchewan, Canada. He alerted the Royal Tyrrell Museum, and crews collected the bones between 2022 and 2025.
