Fossils in Waiting

Fossils recovered from the Ice Age site sit in the Denver Museum of Nature & Science's conservation lab in an undated picture. The Ice Age cache is unusual because of its high altitude and the diversity of animals, plants, and insects that have accumulated there over the millennia, experts say.
High-altitude sites are "consistently underrepresented" in the Ice Age fossil record, said Daniel Fisher, a mastodon expert at the University of Michigan. (Related picture: "Oldest Art in Americas Found on Mammoth Bone?")
"There have been suggestions that high-altitude environments might have harbored different communities, or had a different story of change, but since fossils representing them are so rarely found, no one has known for sure," Fisher said in a statement.
"Now is our chance to see what they are like."
