Mosasaurini is an extinct tribe of mosasaurine mosasaurs who lived during the Late Cretaceous and whose fossils have been found in North America, South America, Europe, Africa and Oceania, with questionable occurrences in Asia.
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]
The subfamily is generally recognised as containing two subdivisions, the tribes Globidensini (Globidens and its closest relatives) and Mosasaurini (Mosasaurus and its closest relatives). A third tribe, the Prognathodontini (Prognathodon and its closest relatives, such as Plesiotylosaurus), is also used on occasion. [6] "
The specific placement of Mosasauria within the Squamata has been controversial since its inception, with early debate focusing on the classification of the mosasaurs. Cuvier was the first scientist to deeply analyze their possible taxonomic placement through Mosasaurus. While his original 1808 hypothesis that the genus was a lizard with ...
Some mosasaurs measured just a few feet long, while the largest — in the genus Mosasaurus — was nearly 60 feet (18.2 meters) long, and while mosasaur fossils are relatively plentiful ...
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.
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).
Some of the dinosaurs who lived there were the ankylosaurs, the mosasaurs, and the plesiosaurs. #10. Image credits: ralph_the_rex #11. Image credits: ralph_the_rex #12.
