Basilosaurus is thought to have been one of the largest animals of the Paleogene, with the type species B. cetoides measuring around 17–20 metres (56–66 ft) long and weighing up to 15 metric tons (17 short tons). It was the top predator of its environment in the shallows of the inland sea, preying on sharks, large fish and other marine mammals.
It was designated a UNESCO World Heritage Site [2] in July 2005 [3] for its hundreds of fossils of some of the earliest forms of whale, the archaeoceti (a now extinct sub-order of whales). The site reveals evidence for the explanation of one of the greatest mysteries of the evolution of whales : the emergence of the whale as an ocean-going ...
The largest known New World monkey was Cartelles, which is studied as specimen of Protopithecus, weighing up to 34.27 kg (75.6 lb). Caipora bambuiorum is another large species, weighing up to 27.74 kg (61.2 lb). [231] The largest omomyids were Macrotarsius and Ourayia from the Middle Eocene. Both reached 1.5–2 kg (3.3–4.4 lb) in weight. [232]
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 ...
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 ...
Livyatan is the largest fossil sperm whale discovered, and was also one of the biggest-known predators, having the largest bite of any tetrapod. [ 1 ] [ 8 ] Diagram comparing the upper and lower size estimates of Livyatan (bottom three) with the size of mature sperm whales, including one of the largest individuals recorded (top three), and a human
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 ...
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 ...
