LAS VEGAS (AP) - A University of Nevada, Las Vegas, paleontologist is trying to identify apparent dinosaur bone fossils found in a state park about 20 miles west of the Las Vegas Strip.
Josh Bonde tells the Las Vegas Review-Journal the fossilized backbone vertebrae comes from a layer of rock dating to the late Triassic period.
That's 220 million to 230 million years ago, and it would predate dinosaur footprints spotted in nearby red rock sandstone in 2010.
There's no positive identification yet, but Bonde thinks it might be the oldest land animal fossil ever found in Nevada.
The Review-Journal says searchers found more fossilized bones and fragments over the weekend in the Spring Mountain Ranch State Park area where 84-year-old Harold Larson found the first specimen a few months ago.
