PORTLAND, Ore. (AP) – Scientists at the University of Oregon have discovered a dinosaur bone, the first fossil of a prehistoric terrestrial creature residing in this state.
Oregonian / Oregon Live indicates that the discovery took place in 2015 when Earth Science professor Greg Retallack was in central Oregon, leading a field expedition of students looking for plants fossilized near the city of Mitchell.
The group fell on a pile of ammonites, spiral-shaped sea creatures that disappeared at about the same time as the dinosaurs.
The revelation of Retallack was first revealed in an article published this month in the Journal of Vertebrate Paleontology.
The fossil, a toe, would be about 103 million years old and would date back to the Cretaceous. It belonged to a creature called ornithopod, a 17-foot herbivore (a little over 5 meters) that weighed up to 680 kilograms and walked on two legs.
