T. littoralis was described from a nearly complete skull, MUSM SAS 1615, in 2002. Fossils found to date have been from the coast of Peru and Chile. This also increased the size of the mouth. Negative buoyancy requires dense bones and a limited layer of blubber, which would make thermoregulation difficult for them in cooler water temperatures, particularly in view of the low metabolic rate of xenarthrans.
