Megafauna in Arctic

Caption

Some 125,000 years ago, during a warm interval known as the last interglaciation, megafaunal mammals were able to penetrate parts of northern North America that had previously been covered by massive ice sheets. In this reconstruction, in addition to the American mastodon (Mammut americanum), illustrated is Jefferson's ground sloth (Megalonyx jeffersonii), the flat-headed peccary (Platygonus compressus), and the western camel (Camelops hesternus).
