Barosaurus When paleontologist David Evans arrived at the ROM earlier this year, he realized that fossils thought to be random bones from many different individuals actually belonged to a single skeleton. And no ordinary skeleton--it turned out to be an impressive 90-foot-long Barosaurus, a Brontosaurus-like sauropod from the Jurassic period. This rare specimen of one of the largest animals ever to walk the earth had been languishing undocumented in the Museum's vaults for nearly 45 years.
