Tullimonstrum gregarium, colloquially known as the Tully Monster, was a soft-bodied invertebrate that lived in shallow tropical coastal waters of muddy estuaries during the Pennsylvanian geological period, about 300 million years ago. Examples of Tullimonstrum have been found only in the Mazon Creek fossil beds of Illinois, United States.
