The most common mammals in Michigan's Pleistocene fossil record were caribou, elk, Jefferson mammoths, American mastodons, and woodland muskoxen. Less common members of Michigan's fossil record included black bears, giant beavers, white-tailed deer, Scott's moose, muskrats, peccaries, and meadow voles. [10]

A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata. [1] Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern (and some in the northeastern) portion of Michigan's lower peninsula.
The fossil had been discovered upright in the sand during the excavation of a cellar in Genesee County.
