Himalayacetus is an extinct genus of carnivorous aquatic mammal of the family Ambulocetidae. The holotype was found in Himachal Pradesh, India, ( 31°00′N 77°00′E / 31.0°N 77.0°E: paleocoordinates 3°30′N 69°42′E / 3.5°N 69.7°E) [2] in what was the remnants of the ancient Tethys Ocean during the Early Eocene. This makes Himalayacetus the oldest archaeocete known, extending the fossil record of whales some 3.5 million years. [3]
Himalayacetus lived in the ancient coastline of the ancient Tethys Ocean before the Indian Plate had collided with the Cimmerian coast. Like Gandakasia, Himalayacetus is only known from a single jaw fragment, making comparisons to other ambulocetids difficult. [4]
Upon its discovery, Himalayacetus was described as a pakicetid because the dentary has a small mandibular canal and a dentition similar to Pakicetus. [3] Thewissen, Williams & Hussain 2001 assigned Himalaycetus to the ambulocetids.
Himalayacetus was named by Bajpai & Gingerich 1998. Its type is Himalayacetus subathuensis after the Himalayas, cetus, "whale", and the Subathu Formation, the type locality. [5]
It was considered monophyletic by Uhen (2010). It was assigned to Pakicetidae by Bajpai and Gingerich (1998) and McLeod and Barnes (2008); and to Ambulocetidae by Thewissen et al. (2001) and Uhen (2010). [6]
