Pakicetus (meaning 'whale from Pakistan') is an extinct genus of amphibious cetacean of the family Pakicetidae, which was endemic to Indian Subcontinent during the Ypresian (early Eocene) period, about 50 million years ago. [2]
The earliest known ancestor of arctic whales is Denebola brachycephala from the late Miocene around 9–10 million years ago. [55] A single fossil from Baja California indicates the family once inhabited warmer waters. [27] [56] [57] Acrophyseter skull. Ancient sperm whales differ from modern sperm whales in tooth count and the shape of the ...
They are related to the Indohyus, an extinct chevrotain-like ungulate, from which they split approximately 48 million years ago. [21] [22] Primitive cetaceans, or archaeocetes, first took to the sea approximately 49 million years ago and became fully aquatic 5–10 million years later. What defines an archaeocete is the presence of anatomical ...
Artiocetus clavis was a small whale measuring 2–3 m (6.6–9.8 ft) long. [2] It existed in the early Lutetian age (47 million years ago) and is one of the oldest known protocetid archaeocetes. Though the whale may have been primarily aquatic, the discovery of ankle bones lends to the idea that this fossil may have been a transition between ...
Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said ...
Ambulocetus (Latin ambulare "to walk" + cetus "whale") is a genus of early amphibious cetacean [a] from the Kuldana Formation in Pakistan, roughly 48 or 47 million years ago during the Early Eocene . It contains one species , Ambulocetus natans (Latin natans "swimming"), known solely from a near-complete skeleton.
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago. A teen found a 34-million-year-old whale skull in her ...
Roger Searle Payne (January 29, 1935 – June 10, 2023) was an American biologist and environmentalist famous for his 1967 discovery (with Scott McVay) of whale song among humpback whales. Payne later became an important figure in the worldwide campaign to end commercial whaling .
