Size compared to a human. Basilosaurus is one of the largest animals known to exist between the K–Pg extinction event 66 million years ago (mya) and around 15 million years ago when modern cetaceans began to reach enormous sizes. [51] [52] B. cetoides measured 17–20 metres (56–66 ft) long and B. isis measured 15–18 metres (49–59 ft ...
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
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
The blue whale is the largest animal known ever to have existed. [42] [43] [44] 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).
Size of Baird's beaked whale compared to an average human Size of Arnoux's beaked whale compared to an average human Size of Sato's beaked whale compared to a human. The two established species, Baird's and Arnoux's beaked whales, have very similar features and would be indistinguishable at sea if they did not exist in disjoint locations. [33]
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]

Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the largest known animal that has ever lived. The sperm whale is the largest toothed predator on Earth.
