Imperial mammoths, largest of the elephant folk, stood 4. Lighter of petroleum evaporate from the asphalt, leaving a more solid substance, which encases the bones. Normally, the asphalt appears in vents, hardening as it oozes out, to form stubby mounds. Preservation can mean bones replaced by mineralization to give us skeletal remains, impressions in fine sediment retaining incredible detail, or entire animals trapped in the resin of a tree, that later hardens into a transparent time capsule.
