Pohlsepia mazonensis is the earliest described octopod, dated at approximately 296 million years old. The species is known from a single exceptionally preserved fossil discovered in the Pennyslvanian Francis Creek Shale of the Carbondale Formation, NE Illinois, USA.[1]
Pohlsepia mazonensis is named after its discoverer, James Pohl, and the type locality, Mazon Creek. Its habitat was the shallows seawards of a major river delta in what at that time was an inland ocean between the Midwest and the Appalachians.[1]
The type specimen is deposited at the Field Museum of Natural History in Chicago, Illinois.[1]
