Summary

[edit]
Description
English: The 2012 National Fossil Day artwork features a familiar face: the mammoth. Mammoths are extinct, large, herbivorous mammals from the same family as the modern elephant. The oldest mammoth fossils are from the early Pliocene epoch (about 5 million years ago). Nearly all populations of mammoths were extinct by about 10,000 years ago, although some isolated populations may have lived until about 5,000 years ago. Globally, the Pliocene climate was much cooler and drier than during the Cretaceous, which was home to the mosasaurs and ammonites featured on the 2011 artwork. Following the Pliocene, Earth's climate was cold enough to support large ice sheets on both the North and the South poles—setting the stage for the Pleistocene ice ages. During an ice age, immense sheets of ice advanced from the poles.
