Thats what were finding now, explained Crystal Czarniecki, assistant curator for the Earth Science Museum at the University of Waterloo. The American mastodon went extinct between 10,000 and 11,000 years ago, while small populations of mammoths existed in Alaska as recently as 1650 BC, before disappearing completely. [7] Fossil lungfish burrows are another interesting find from the Pennsylvanian coal swamp deposits near Grand Ledge in Clinton County but these tend to be poorly preserved.
