University of Oregon scientists said they have found the first confirmed a rare dinosaur bone in Oregon.

University of Oregon scientists said they have uncovered a rare Oregon dinosaur fossil.

The toe bone belonged to a plant-eating, bipedal dinosaur known as an ornithopod and is estimated to date back 103 million years to a geological period that also gave rise to Tyrannosaurus Rex, the university said.

The university said it is a rare find because the state was underwater for most of the dinosaur age, according to Fox 12.

Retallack said the dinosaur, which was more than 20 feet long and weighed nearly a ton, likely died onshore and washed out to sea. The discovery was reported last week in the Journal of Vertebrate Paleontology, a peer-review publication, according to reports.
