Mosasaurus fossils have been found in North and South America, Europe, Africa, Western Asia, and Antarctica. This distribution encompassed a wide range of oceanic climates including tropical, subtropical, temperate, and subpolar. Mosasaurus was a common large predator in these oceans and was positioned at the top of the food chain.
The Mosasaurus hoffmannii skull found in Maastricht between 1770 and 1774. The first publicized discovery of a partial fossil mosasaur skull in 1764 by quarry workers in a subterranean gallery of a limestone quarry in Mount Saint Peter, near the Dutch city of Maastricht, preceded any major dinosaur fossil discoveries, but remained little known.
An 1854 depiction of Mosasaurus in Crystal Palace Park. One of the earliest paleoart depictions of Mosasaurus is a life-size concrete sculpture constructed by natural history sculptor Benjamin Waterhouse Hawkins between 1852 and 1854 as part of the collection of sculptures of prehistoric animals on display at the Crystal Palace Park in London.
New mosasaur specimens, such as NDGS 10838, help experts to unravel “the rich evolutionary history of these rather charismatic apex predators of the Cretaceous seas,” he said.
Instead, they primarily relied on stratigraphic associations and Cuvier's 1808 research on the holotype skull. Thus, in-depth research on the placement of Mosasaurus was not undertaken until the discovery of more complete mosasaur fossils during the late 19th century, which reignited research on the placement of mosasaurs among squamates.

Life restoration of the mosasaur Hainosaurus feeding on a cephalopod. This timeline of mosasaur research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, and taxonomic revisions of mosasaurs, a group of giant marine lizards that lived during the Late Cretaceous Epoch. Although mosasaurs went ...
Jormungandr is a large mosasaur. The holotype skull measures 72 centimeters (28 in) in total length and the lower jaw is 80.8 centimeters (31.8 in) long. [ 2 ] Based on these measurements, Zietlow and colleagues estimated a total body length of 5.4–7.3 meters (18–24 ft).
