Albertocetus

Albertocetus is an extinct genus of primitive odontocete cetacean from early Oligocene (Rupelian) marine deposits in North Carolina, and belonging to the family Xenorophidae.

Description
Albertocetus is a relatively small whale, measuring 1.82 m long and weighing approximately 51 - 73 kg. It is distinguished from other xenorophids in having a large lacrimal bone, a steep ascending process of the maxilla, a short but present intertemporal constriction with a sagittal crest, and a tall median ridge on the premaxilla. The teeth were heterodont, and may have been polydont, because other xenorophids are polydont.
