Researchers at the University of Oregon discovered the first confirmed dinosaur bone in Oregon, Fox 12 Oregon reports.
The finger bone belonged to a dinosaur that is a herbivorous, bipedal dinosaur known as ornithopus, and is estimated to be 103 million years old back into the geological period that led to the formation of Tyrannosaurus Rex.
"That bone was sitting there with all the rocks." That was quite surprising, "a University of Oregon scientist, Greg Retallack, said Eugene Register-Guard. "There was no need for excavations. He sat among ammonites and fossils curled up.
Retallack found him in eastern Oregon near the small town of Mitchell.
The University said it was a rare discovery because the state was under water for most of the dinosaur age, according to Fox 12.
Retallack said the dinosaur, which was over 20 feet long and weighed nearly a ton, probably died on land and sailed out to sea.
The discovery was made last week in the Journal of Vertebrate Paleontology, a review article, according to reports.
