Skeletons of basilosaurid whales like Dorudon (featured above) were discovered at the site. Wādī al-Ḥītān is the most important site in the world to demonstrate one of the iconic changes that make up the record of life on Earth: the evolution of the whales.
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.
If true, it would make Bruhathkayosaurus the single largest terrestrial animal to have walked the earth and would have rivalled the largest blue whale recorded. [ 416 ] BYU 9024, a massive cervical vertebra found in Utah , [ 417 ] may belong to a Barosaurus lentus [ 418 ] [ 419 ] or Supersaurus vivianae [ 420 ] of a huge size, possibly 45–48 ...
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 ...
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 ...
The largest known basilosaurid, Perucetus colossus, is believed to be even bigger, with a length of about 17–20 metres (56–66 ft) and possibly comparable to, if not larger than, the modern blue whale in terms of weight, [15] though other researchers argue that it was much lighter. [16] [17]
Scientists consider the blue whale, which grows up to 110 feet (33.5 meters) long, to be the largest known animal ever to exist on the planet. But it’s possible that the 202 million-year-old ...
