Reported byPopular Science ↗·Sourced by Goodlede
Paleontologists examined 3,013 fossilized bones from Wyoming dated to 72-66 million years ago and identified 4 distinct tooth mark patterns matching T. rex bites on Edmontosaurus annectens remains, published today in PLOS One. The findings help reconstruct predator-prey interactions in late Cretaceous ecosystems.
