This is part of a group of marine reptiles which attained great size in the Cretaceous before becoming extinct, forerunners of the great sharks and cetaceans which post the great extinction (the KT boundary) filled the top of the food chain predatory gap, the mosasaurus demise created in the earth's oceans.

Details

A double-sided Prognathodon Mosasaur jaw section exhibiting large complete articulated teeth to both faces, teeth within their original jaw positions. The teeth exhibiting a fine caramel or toffee colour to the crown of dentin-enamel, stock-root solidly fixed into the original seating position in the predator's fossilised mandibles. The Mosasaurs with the extinction of the ichthyosaurs and pliosaurs became the dominant marine predators of the age.


The Cretaceous period Mosasauroidea, marine reptiles featured in the Jurassic Park and Jurassic World series of films. The Mosasaurs were a group of perfectly developed marine predators, resembling a crocodilian and lizard form, huge double-hinged jaws and skulls armed with many large teeth; It is thought they could unhinge their jaws and gulp down large prey. Armed with powerful flippers and streamlined bodies. When first studied, it was thought Mosasaurs used their bodies like snakes or eels when swimming, undulating side to side when swimming. However, the most recent research nows leads us to theorise their bodies remained stiff and a large fluked tail provided the locomotion which propelled the Mosasaur, similar to modern-day sharks and cetaceans.


Part of a more ancient group of aquatic lizards, the aigialosaurs group. Mosasaurs breathed air, gave birth to live young and grew from around 3 feet; Dallasaurus turneri, the smallest Mosasaur to 50 feet in length; Mosasaurus hoffmannii, being the largest. The Mosasaurs reigned for around 20 million years before the mass extinction which also ended the dinosaurs' existence, around 65 million years ago at the K-T boundary event. This was the last 20 million years of the Cretaceous period. The Turonian to Maastrichtian ages.


The first fossils were discovered in an 18th-century limestone quarry near Maastricht on the river Meuse. When first discovered the skeleton was thought to be that of a dragon and the major of Maastricht had the fossil bones put on display in a glass case for all to marvel at the size of the amazing new discovery.
