Scientists Have Evidence That Dinosaurs Once Roamed Washington State
Make no bones about it: Washington state was once home to dinosaurs — and scientists now have evidence.
Paleontologists with the University of Washington’s Burke Museum confirmed in a study published Wednesday in the journal PLOS ONE that a fossilized bone discovered in 2012 is in fact the state’s first dinosaur.
A team of scientists looking for prehistoric shells unearthed the 80 million-year-old fossil on a beach in the San Juan Islands between Seattle and Vancouver, British Columbia. It is a 16-inch fragment of the left thigh bone of a two-legged carnivorous dinosaur related to Tyrannosaurus rex and the velociraptor, but the paleontologists haven’t been able to identify the exact species because the piece of bone is so small.

“This fossil won’t win a beauty contest,” study co-author and Burke Museum Curator of Vertebrate Paleontology Christian Sidor said in a museum news release. “But fortunately it preserves enough anatomy that we were able to compare it to other dinosaurs and be confident of its identification.”
It took the scientists several years to remove rock from around the fossil, compare it to other known fossils to find a match and then submit their scientific paper through the peer-review process.
“For a long time, we thought very little of the specimen,” Sidor told The Seattle Times. “We didn’t think we could identify it, other than as a large piece of bone. Then we found a critical piece of anatomy.”
