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.

Tyrannosaurs sit at the top of the food chain in the popular imagination, but a newly described fossil from Alberta, Canada, suggests that a much smaller predator may have fed on the carcass of Albertosaurus sarcophagus, a tyrannosaur relative.
