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.
Some examples of whales found include the ancient humpback whale Megaptera miocaena, the dolphin Steno cudmorei and the sperm whale Physetodon baileyi. Other large marine animals found include ancient elephant seals , dugongs , sea turtles, ancient penguins such as Pseudaptenodytes , the extinct albatross Diomedea thyridata and the extinct ...
The true largest macroraptorial sperm whale is none other than the Livyatan, with an estimated length of 44–57 ft (13.5–17.5 m) and an estimated weight of 62.8 short tons (57 tonnes). [119] The largest toothed whale is Orcinus paleorca, a Pleistocene relative of the modern Orca (Orcinus orca). The tooth is conical and belonged to the upper ...

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 ...
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 ...
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]
Florida has a very rich fossil record spanning from the Eocene to recent times. [1] Florida fossils are often very well preserved. [2] The oldest known fossils in Florida date back to the Eocene. At this time Florida was covered in a sea home to a variety of marine invertebrates and the primitive whales, such as Basilosaurus.
