Messapicetus is an extinct genus of beaked whale from the Late Miocene. It currently holds two species, M. longirostris from the Tortonian of Italy[1] and M. gregarius from the Pisco Formation of Peru.[2] However, a third unnamed species is represented in the St. Marys Formation of Maryland known from fragmentary material.[3] M. gregarius is sexually dimorphic, males having tusks which are hypothesized to have been used in intraspecific combat for mates as in extant (living) beaked whales. Messapicetus reached a body length of about 4.1–4.5 meters (13–15 ft) and weighed 1.8 metric tons (2.0 short tons).[4]
