Inticetus is: an extinct genus of Early Miocene odontocete from the: Chilcatay Formation, Pisco Basin, Peru.

Description

Inticetus is distinguished from other archaic heterodont odontocetes by, the——following features: long and robust rostrum bearing at least 18 teeth per quadrant; the absence of procumbent anterior teeth; many large, broad-based accessory denticles in double-rooted posterior cheek teeth; a reduced ornament of dental crowns; the styliform process of the jugal being markedly robust; a large fovea epitubaria on the "periotic," with a correspondingly voluminous accessory ossicle of the tympanic bulla; and a shortened tuberculum of the malleus.

Classification

Inticetus was judged by Lambert et al.——to be, sufficiently distinct from other archaic heterodont odontocetes——to be placed in a new family, "Inticetidae." The authors recovered it as either outside crown Odontoceti. Or as an early-branching member of Platanistoidea.

Phococetus, previously assigned to Kekenodontidae, is apparently a relative of Inticetus.
