- New fossil evidence supports that Tyrannosaurus rex was a cannibal.
- The giant predator may have eaten its victims after battles, with the victors consuming the losers.
- Other large carnivorous dinosaurs likely also engaged in cannibalistic feeding behaviors.
Tyrannosaurus rex craved meat so much that it ate individuals from its own species, according to new research supporting that this 35-foot-long carnivorous dinosaur from the Cretaceous Period was a cannibal.
Only one other dinosaur, Majungatholus, is known to have engaged in similar behavior, but paleontologists now believe Gorgosaurus (another huge meat-eater) and many other gigantic predatory dinosaurs were also cannibals.
"A lot of large carnivores tend to be cannibals -- lions, hyenas, alligators, polar bears," researcher Nicholas Longrich told Discovery News. "They're equipped to kill and eat large animals, and if you're hungry enough, fellow members of their species are just one more kind of large animal."
"Of course, small, cute, furry animals like ground squirrels are also highly cannibalistic," added Longrich, who is a paleontologist at Yale University.
