DescriptionAlbertocetus 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.[1]References1. ^M. D. Uhen. 2008.
