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
The largest animal currently alive is the blue whale. The maximum recorded weight was 190 tonnes (209 US tons) for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33 metres (108 ft), have been recorded but not weighed. [1] [2] [3] It is estimated that this individual could have a mass of 250 tonnes or more.
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 blue whale is the largest animal known ever to have existed. [43] [44] [45] Some studies have estimated that certain shastasaurid ichthyosaurs and the ancient whale Perucetus could have rivalled the blue whale in size, with Perucetus also being heavier than the blue whale with a mean weight of 180 t (180 long tons; 200 short tons).
There could be a new contender for heaviest animal to ever live. While today's blue whale has long held the title, scientists have dug up fossils from an ancient giant that could tip the scales ...
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 ...
Some balaenopterids perhaps rivaled the blue whale in terms of size, [117] though other studies disagree that any baleen whale grew that large in the Miocene. [118] 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 ...
