Terataspis

Terataspis grandis was a huge 60 centimetre long lichid Trilobite from the Devonian. It lived in a shallow sea in what is now New York State and Ontario. No whole specimens have been found, only disarticulated fragments of its exoskeleton, but enough fragments have been found to allow researchers to form reconstructions of the whole animal.
