Terataspis is a comparatively huge, 60 centimetre long lichid trilobite genus from the Early Devonian, about 397 million years ago. 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. The genus only contains one species, T. grandis.

Terataspis grandis, like many other trilobites, was presumed to have been a detritivore that was also an opportunistic predator, preying on small burrowing animals, such as molluscs, worms, or arthropods.^[1]
