Prehistoric animal taxa

Trilobozoa, from Ancient Greek τρεῖς (treîs), meaning "three", λοβός (lobós), meaning "lobe", and ζῷον (zôion), meaning "animal", is a phylum of extinct, sessile animals that were originally classified into the Cnidaria. The basic body plan of trilobozoans is often a triradial or radial sphere-shaped form with lobes radiating from its centre. Fossils of trilobozoans are restricted to marine strata of the Late Ediacaran period.
