Tiucetus is an extinct genus of cetotheriid baleen whale known from the Late Miocene Pisco Formation of Peru.
Description[]
Tiucetus is distinct from other cetotheriids in having a squamosal cleft; from eomysticetids in having comparatively short nasals, a more anteriorly projected supraoccipital and parietal, and a tympanic bulla that is rotated so that the inner posterior prominence faces dorsally.[1]
Classification[]
Tiucetus falls basally in Cetotheriidae, less derived than Joumocetus and Cephalotropis.
Palaeogeography[]
Other marine mammals found in the Pisco Formation include another cetotheriid, Piscobalaena, the odd dolphin Odobenocetops, the killer sperm whale Acrophyseter, the long-necked seal Acrophoca, and aquatic sloth Thalassocnus.
