The Tully Monster (Tullimonstrum gregarious) is an enigmatic creature that lived in a muddy estuarine environment during the Carboniferous Period, about 307 million years ago. It is known only the Mason Creek fossil beds, a rich deposit in northeastern Illinois. It probably used its long proboscis to probe for small prey and edible matter in the mud.
