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 ...
Basilosaurus (meaning "king lizard") is a genus of large, predatory, prehistoric archaeocete whale from the late Eocene, approximately 41.3 to 33.9 million years ago (mya). ). First described in 1834, it was the first archaeocete and prehistoric whale known to scienc
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.
Archaeoceti ("ancient whales"), or Zeuglodontes in older literature, is a paraphyletic group of primitive cetaceans that lived from the Early Eocene to the late Oligocene 1] Representing the earliest cetacean radiation , they include the initial amphibious stages in cetacean evolution , thus are the ancestors of both modern cetacean suborders ...
Iconic assemblage of fossilized skeletons of Archaeoceti (primitive whales documenting cetacean transition to marine life), sirenians and reptiles, as well as shark teeth from Gehannam Formation (40–41 million years ago). [8]
Perucetus colossus, a giant whale that lived almost 40 million years ago is now thought to be the heaviest animal that has ever lived, scientists said Wednesday.
Ankylorhiza (meaning "fused roots"; in reference to the type of dentition seen in early toothed whales) is an extinct genus of toothed whale that lived in what is now the United States during the Oligocene epoch, between 29 and 23.5 million years ago.
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago.
