Etacystis communis, colloquially known as the H-animal or aitch, 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. The classification is uncertain: the animal had a unique H-shaped body ranging from 2 to 11 cm long, and researchers have suggested a hemichordate or hydrozoan affinity. Examples of Etacystis have been found only in the Mazon Creek fossil beds of the Midwestern United States.
