Mosasauridae

They were similar to the monitors, which originated from the primitive. They evolved into many types but all became extinct at the end of the Cretaceous. It existed during the Maastrichtian age of the late Cretaceous perio between about and 66 million years ago, in western Europe, North America, and possibly Japan and New Zealand. It included the species of mosasaurs viz.

Mosasaurus is an aquatic lizard which lived approximately million to million years ago during the Late Cretaceous Period. It was first discovered during the mid-18th century in Maastricht, Netherlands and eventually collected by Jean-Baptiste Drouin.

Mosasaurs were large, predatory marine lizards of the Upper Cretaceous. Overview Mosasaurs are only known from the Late Cretaceous. They were top predators of the Western Interior Seaway and evolved into a diversity of forms during their ~million years of existence. They ranged in size from less than meters (16ft) (Clidastes) to meters (45ft) (Tylosaurus). Meuse River, which inspired the name “mosasaur”.

The fossil skull was discovered in the Netherlands at a limestone quarry near the city, Maastricht. Tylosaurus was one of the larger mosasaurs that lived towards the end of the Cretaceous perio‭ ‬something which has secured its frequent inclusion in popular media such as books and television documentaries. Rivals to Tylosaurus in terms of upper size include Mosasaurus and Hainosaurus.

It often resides towards the edge of the map boundary, and can be surprisingly elusive.

The Mosasaurus is found deep in the ocean and can be quite far from the shore. It behaves similar to the Plesiosaur. Mosasaurus has a fairly average aggro radius, and will pursue the player a fair distance horizontally. However, it will not follow the player.

This subfamily, in turn, is further split into smaller tribes, with Mosasaurus being grouped with Clidastes, Moanasaurus, Amphekepubis, and Liodon in the tribe Mosasaurini. Mosasaurs possessed two types of teeth: they had the usual upper and lower jaw teeth, but they also had a second set of teeth on a separate jaw behind their maxilla, which are called pterygoid teeth. These specialized pterygoid teeth were used to help hold down prey that was struggling to help make swallowing easier.

Mosasaurus was a late mosasaur (a type of aquatic, finne giant predatory lizard from the Cretaceous period). Mosasauridi („ještěři od řeky Mázy“) byli velcí až obří druhohorní mořští plazi ještěrovitého vzhledu. Jejich první rozeznané fosí.

I mosasauri sono un gruppo di rettili marini vissuti nel Cretacico superiore. Probabilmente si svilupparono da rettili semiacquatici noti come aigialosauri verso la fine del Cretaceo inferiore. Durante gli ultimi milioni.

February 1 “The Case of the Creationist Geologist (Letters)”, in. On Home-Earth, the sea turtles are a sole reminder of a lost age when sauropsids ruled the waves. Beneath the waters of Spec however, the turtles are joined by another, far less benign lineage from the Cretaceous, the fearsome mosasaurs. Unlike the other major groups, mosasaurs are only known from the Late Cretaceous.

There is a small overlap with the stratigraphic range of Ichthyopterygia in the Cenomanian, but no locality is yet known to yield both. The Squamata is the sister group to the Rhynchocephalia (the Tuatara and extinct relatives), sharing a common ancestor around 2million years ago at the start of the Mesozoic. Together, they form the monophyletic Lepidosauria.
