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] Fossils attributed to the type species B. cetoides were discovered in the ...
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 ...
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 ...
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 ...
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 ...
Zygorhiza ("Yoke-Root") is an extinct genus of basilosaurid early whale known from the Late Eocene (Priabonian, 38–34 Ma) of Louisiana, Alabama, and Mississippi, United States, and the Bartonian (43–37 Ma on the New Zealand geologic time scale) to the late Eocene of New Zealand (1]
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.
