Mosasaurus fossils have been found in North and South America, Europe, Africa, Western Asia, and Antarctica.

Mosasaurus was a common large predator in these oceans and was positioned at the top of the food chain.
After it had been earlier interpreted as a fish, a crocodile, and a sperm whale, the first to understand its lizard affinities was the Dutch scientist Adriaan Gilles Camper in 1799. In 1808, Georges Cuvier confirmed this conclusion, although le Grand Animal fossile de Maëstricht was not actually named Mosasaurus (' Meuse reptile') until 1822 ...
Some balaenopterids perhaps rivaled the blue whale in terms of size, [114] though other studies disagree that any baleen whale grew that large in the Miocene. [115] 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 ...

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.
An 1854 depiction of Mosasaurus in Crystal Palace Park.

The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale.Reaching a maximum confirmed length of 29.9 m (98 ft) and weighing up to 199 t (196 long tons; 219 short tons), it is the largest animal known ever to have existed.
