Examples of "ambulocetidae"
Remingtonocetids lived in the Middle-Eocene in South Asia, about 49 to 43 million years ago. Compared to family Pakicetidae and
, Remingtonocetidae was a diverse family found in north and central Pakistan and western India. Remingtonocetids were also found in shallow marine deposits, but they were obviously more aquatic than
. This is demonstrated by the recovery of their fossils from a variety of coastal marine environments, including near-shore and lagoonal deposits. According to stable oxygen isotopes analysis, most remingtonocetids did not ingest fresh water, and had hence lost their dependency on fresh water relatively soon after their origin.
It was considered monophyletic by Uhen (2010). It was assigned to Pakicetidae by Bajpai and Gingerich (1998) and McLeod and Barnes (2008); and to
by Thewissen et al. (2001) and Uhen (2010).
"Ambulocetus" is classified under the monophyletic family
. The family is believed to have diverged from the more terrestrial Pakicetidae. The families Protocetidae and possibly Remingtonocetidae, are believed to have arisen from a common ancestor with ambulocetids. Together with Basilosauridae, the five families are classified under the suborder Archaeoceti.
Himalayacetus is an extinct genus of carnivorous aquatic mammal of the family
. The holotype was found in Himachal Pradesh, India, (: paleocoordinates ) 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.
Ambulocetus (meaning "walking whale") was an early cetacean with short limbs and large feet used for swimming. Along with other members of
, it is a transitional fossil that shows how whales evolved from land-living mammals. While its name stems from the historical hypothesis that it was capable of walking on land, more recent research suggests that it was fully aquatic like modern cetaceans.
is a family of early cetaceans from Pakistan. The genus "Ambulocetus", after which the family is named, is by far the most complete and well-known ambulocetid genus due to the excavation of an 80% complete specimen of "Ambulocetus natans". The other two genera in the family, "Gandakasia" and "Himalayacetus", are known only from teeth and mandibular fragments. Retaining large hindlimbs, it was once thought that they could walk on land - indeed, their name means "walking whales" -, but it is now known that they were fully aquatic like modern cetaceans.
Dalanistes is an extinct genus of remingtonocetid early whale known from the late early Eocene (Lutetian, ) of Kutch, India and Punjab and Balochistan, Pakistan. "Dalanistes" is closely related to "Remingtonocetus" (the type genus of Remingtonocetidae, a slightly more derived family of early whales), but also shares several characters with "Ambulocetus" (the type of
, earlier more primitive whales), and, with its combination of terrestrial and amphibious adaptations, "Dalanistes" apparently is an intermediate form between these two groups. Isotopic evidence suggest that "Dalanistes" had a marine diet.
