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.
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.
Mosasaur teeth are of rather uniform morphology (with a few exceptions, such as in Globidens) with a pointed and curved tooth crown that sits on a pedicel composed of bone. [7] The enamel surface is smooth and the crown is subdivided into a lingual and labial surface while the outer surface of the crown is made of enamel and the inner layer is ...
The smaller mosasaurs may have spent some time in fresh water, hunting for food. The largest mosasaur Mosasaurus hoffmannii was the apex predator of the Late Cretaceous oceans, reaching more than 11 metres (36 ft) in length and weighing up to 10 metric tons (11 short tons) in body mass. [14]
Appendicular elements with smoothly finished articular surfaces, tarsus and carpus well ossified." In his 1997 revision of the phylogeny of the Mosasauroidea, Bell (pp. 293–332) retained the Mosasaurinae as a clade , though he reassigned Russell's tribe Prognathodontini to the Mosasaurinae and recognized a new tribe of mosasaurines, the ...
This is a list of stratigraphic units from which mosasaur body fossils have been recovered. Units listed are all either formation rank or higher (e.g. group). Formations are listed by continent, and alphabetically within the individual lists.
A significant mosasaurus skull was taken by the French during the Siege of Maastricht, and has been housed at the French National Museum of Natural History since 1794. Multiple attempts have been made since 1824 to have the piece returned to Maastricht. [4] The museum also has a period room with cabinets of curiosities.
The Goldfuss Mosasaur MNHN 9587/RFWUIP 1327 Muséum national d'Histoire Naturelle/Goldfuß Museum Campanian: DeGrey Formation (Pierre Shale Group) [5] South Dakota MNHN 9587 and RFWUIP were uncovered separately. [6] MNHN 9587 was originally assessed as 'Ichtyosaurus missouriensis', [7] while RFWUIP 1327 was described as 'Mosasaurus maximiliani ...
