Peregocetus is the first recorded quadrupedal whale from the Pacific Ocean and the Southern Hemisphere. The discovery reveals that protocetids reached the Pacific Ocean and attained a near circumequatorial distribution while retaining functional weight-bearing limbs. [1]
Cetacean bones of the same period were also found in the area, reflecting the importance of whales in the diet of prehistoric coastal people. Whale bones recovered near the Strait of Gibraltar raise the possibility that whales were hunted in the Mediterranean Sea by ancient Rome. [5] [6]
Aetiocetidae is an extinct family of toothed baleen whales known from the Oligocene and latest Eocene, so far only from rocks deposited in the North Pacific Ocean. [3] [4] [5] The whales ranged in size from 3 to 8 metres (10 to 26 ft) long.
Aetiocetus is a genus of extinct basal mysticete, or baleen whale that lived , in the Oligocene in the North Pacific ocean, around Japan, Mexico, and Oregon, U.S. It was first described by Douglas Emlong in 1966 and currently contains known four species, A. cotylalveus, A. polydentatus, A. tomitai, and A. weltoni.

The first spade-toothed whale bones were found in 1872 on New Zealand’s Pitt Island. Another discovery was made at an offshore island in the 1950s, and the bones of a third were found on Chile ...
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago.
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 science. [ 2 ]
Among the baleen whales found, the most common was an undescribed species of cetotheriid whale measuring around 5 to 8 m (16 to 26 ft), and most of the other baleen whales found were roughly the same size. Toothed whale remains found consist of beaked whales (such as Messapicetus gregarius), ancient pontoporiids (such as Brachydelphis mazeasi ...
