It contains one species, Ambulocetus natans (Latin natans "swimming"), known solely from a near-complete skeleton. Ambulocetus is among the best-studied of Eocene cetaceans, and serves as an instrumental find in the study of cetacean evolution and their transition from land to sea, as it was the first cetacean discovered to preserve a suite of ...
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. [2] The other two genera in the family, Gandakasia and Himalayacetus, are known only from teeth and mandibular fragments. [3]
Though they were probably able to live on land, they apparently used their tails to swim. [7] Dozens of fossils have been described, but most are only skulls and lower jaws with few dental and postcranial remains. Remingtonocetids probably varied in size with the smallest species matching Pakicetus and the largest Ambulocetus. Remingtonocetids ...
Ambulocetus natans, which lived about 49 million years ago, was discovered in Pakistan in 1994. It was probably amphibious, and looked like a crocodile . [ 24 ] In the Eocene, ambulocetids inhabited the bays and estuaries of the Tethys Ocean in northern Pakistan. [ 25 ]
Johannes Gerardus Marie (Hans) Thewissen is a Dutch-American paleontologist known for his significant contributions to the field of whale evolution.Thewissen's fieldwork has led to the discovery of key fossils that have shed light on the transition of whales from land to water, including the discovery of Ambulocetus, Pakicetus, Indohyus, and Kutchicetus.
Ambulocetus natans is a species of early amphibious archaeocete cetacean from the Early Eocene Kuldana Formation in Pakistan, 48 or 47 million years ago. It is among the most completely known Eocene cetaceans, vital to the study of cetacean evolution and the transition from land to sea.
The transition from land to sea dates to about 49 million years ago, with the Ambulocetus ("running whale"), also discovered in Pakistan. It was up to 3 m (9.8 ft) long. The limbs of this archaeocete were leg-like, but it was already fully aquatic, indicating that a switch to a lifestyle independent from land happened extraordinarily quickly. [83]
