Fossils were later found of the second species, B. isis, in 1904 in Egypt, Western Sahara, Morocco, Jordan, Tunisia, and Pakistan. [3] Fossils have also been unearthed in the southeastern United States and Peru. [4] [5] [6] Basilosaurus is thought to have been common in the Tethys Ocean. [7] [8] It was one of the largest animals of the Paleogene.
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 ...
They calculated that the ancient giant weighed somewhere between 94 and 375 tons (85 and 340 metric tons). The biggest blue whales found have been within that range — at around 200 tons (180 ...
The fossils of whales vary from single bones to entire skeletons, and a number of partial skeletons are currently on display in the public part of the park. The two common whales are the large Basilosaurus, and the smaller (3- to 5-metre) Dorudon. [10] At least two other species are known from rarer remains.
A newly discovered ancient species of whale may be one of the largest and heaviest animals on record, a new study has found. A newly discovered colossal whale might be the heaviest animal ever ...
This week, meet a colossal ancient whale, learn what happens when researchers tickle rats, see starry images from a new telescope, and more. Newly discovered ancient creature may have been the ...
Perucetus is the largest Eocene whale measuring about 17–20 meters (56–66 ft) long. Some researchers claim that it may have rivaled or exceeded the modern blue whale in weight, partly due to the incredibly thick and dense bones this animal possessed, coupled with its already great size, while others argue that it was much lighter.

There is a new contender for the most massive animal in Earth's history. Scientists on Wednesday described fossils of an early whale unearthed in Peru called Perucetus colossus that lived about 38 ...
