Tooth in Skull Reveals Rare T. rex Attack on Edmontosaurus
TL;DR
Paleontologists describe a nearly complete Edmontosaurus skull with a Tyrannosaurus tooth embedded in its snout and bite marks suggesting a fatal, close-range encounter. CT analysis indicates the tooth broke off during the attack, with the Edmontosaurus unlikely to survive; size estimates point to an adult T. rex with about a 1-meter-long skull. The find provides rare direct fossil evidence of predation and feeding behavior in large theropods, showing T. rex likely hunted and scavenged during its life.
