[60] [61] Earlier variety were probably preyed upon by killer sperm whales and large sharks such as megalodon. In 2008, a large number of fossil ziphiids were discovered off the coast of South Africa, confirming the remaining ziphiid species might just be a remnant of a higher diversity that has since gone extinct.
Perucetus is an extinct genus of an early whale from Peru that lived during the Bartonian age of the middle Eocene. Perucetus is the largest Eocene whale, with length estimates varying from 15–16 meters (49–52 ft) to 17–20 meters (56–66 ft).
Between 1889 and 1903 nine more companies established themselves in Iceland. Catching peaked in 1902, when 1,305 whales were caught to produce 40,000 barrels of oil. Whale hunting had largely declined by 1910, when only 170 whales were caught. A ban on whaling was imposed by the Althing in 1915. In 1935 an Icelandic company established a ...
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
The next diverging family of whales, the Ambulocetidae, were large, already fully aquatic, [8] and crocodile-like with large feet and a strong tail. Sediments indicate that they lived in coastal areas and their compact bones suggest that they were ambush rather than fast-pursuit predators.
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago.
Protocetus atavus ("first whale") is an extinct species of primitive cetacean from Egypt.It lived during the middle Eocene period 45 million years ago. The first discovered protocetid, Protocetus atavus was described by Fraas 1904 based on a cranium and a number of associated vertebrae and ribs found in middle Lutetian Tethyan marine limestone from Gebel Mokattam near Cairo, Egypt.
The list of extinct cetaceans features the extinct genera and species of the order Cetacea. The cetaceans (whales, dolphins and porpoises) are descendants of land-living mammals, the even-toed ungulates. The earliest cetaceans were still hoofed mammals.
