Mosasaurs.

Mosasaurs show a range of body sizes, from a few metres long to giants over 10 metres long. They also evolved an astonishing variety of tooth shapes : hooks, spikes, cones, blades, crushing molars.

The mosasaurs were a group of swimming reptiles that originated in the Late Cretaceous period of the Mesozoic era roughly 95 million years ago, and would go on to become the dominant large marine predators of the era. Importantly, mosasaurs were not dinosaurs, they were an entirely different class of reptile, in the squamate group.Animated size comparison of some of the largest mosasaurs.Mosasaurs are extinct ocean and sea reptiles who lived during the Late Cretaceous period.

The megalodon approaches the mosasaur, but as it begins to open its mouth, the mosasaur is able to dodge it. This is because, unlike the megalodon, the mosasaur has defensive traits. Although it was the apex predator in its time, mosasaurs would also hunt each other. This means the mosasaur knows how to fight.Mother mosasaurs would have laid thin, soft-shelled eggs that their babies immediately hatched from to surface and take their first breaths.

Larger mosasaurs were more typical: mosasaurs ranged in size up to 17 meters. Hainosaurus holds the record for longest mosasaur, at 17.5 meters.

The Meuse River was the locality were the first mosasaur was found (Everhart ...Weight of Mosasaurus. The weight of Mosasaurus is estimated to be between 5,000 to 8,000 kg (11,000 to 17,600 lbs.). however this is the estimate for the 30 plus feet Mosasaurus. if it was indeed up to 50 feet plus in length then it would have weighed upwards of 15,000 kg ( 36000 lbs.) and if that length probably considerably more.A fossil mosasaur skull and partial skeleton excavated from Angola's costal cliffs for display in "Sea Monsters Unearthed.".

These were a group of large marine reptiles and were the dominant marine predators for millions of years up until the end of the Cretaceous period. The Mosasaurus was one of the largest mosasaurs known and scientists continue to argue if it's closest living relatives are snakes or lizards.

Mosasaurs were only distantly related to the pliosaurs and plesiosaurs (sea serpents) that preceded them (and which they largely supplanted from the dominance of the world's oceans during the late Cretaceous period). Today, evolutionary biologists believe they were most closely related to modern-day snakes and monitor lizards.In this video I will quickly cover the Mosasaurs, Plesiosaurs, and Ichthyosaurs that lived during the Mesozoic, highlighting just briefly these three groups ...Studies have shown that dinosaurs are terrestrial reptiles that can walk upright on their hind limbs.

Dinosaurs belong to vertebrates and most of them are reptiles, while Pterosauria belongs …Unfortunately for Mosasaurus, few animals match Megalodon when it comes to sheer bite force. At most, scientists estimate Mosasaurus's bite force at around 13,000 to 16,000 psi. This pales in comparison to Megalodon's bite force of 24,000 to 41,000 psi. If accurate, Megalodon would's bite would register as the strongest of any known animal.While dinosaurs ruled the land, the ichthyosaurs, classified variously in the Ichthyosauria or in the Ichthyopterygia, shared the seas of the world with the other great groups of large marine reptiles, the plesiosaurs and mosasaurs. "Ichthyosaur" means "fish lizard," while "Ichthyopterygia" means "fish paddle." Both names are apt.

That gives strong credence to two previous proposals: that mosasaurs lived in the open ocean, not lurking exclusively near coastlines, as previously believed; and that they gave birth to live young. "It really speaks to the value of the fossil record, that only the fossil record can provide direct evidence of the history of life," Field says.Mosasaurs were the apex predators of the Late Cretaceous seas and became extinct along with non-avian dinosaurs 66 million years ago. A Mosasaurus skeleton at the Canadian Fossil Discovery Centre ...The flipper arrangement is unusual for aquatic animals in that probably all four limbs were used to propel the animal through the water by up-and-down movements. The tail was most likely only used for helping in directional control. This contrasts to the ichthyosaurs and the later mosasaurs, in which the tail provided the main propulsion.Mosasaurus is an aquatic lizard which lived approximately 70 million to 65 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. However, that fossil was incomplete and consisted of only the skull of the animal.

The Bench 19 Bonebed at Bentiaba, Angola, is a unique concentration of marine vertebrates preserving six species of mosasaurs in sediments best correlated by magnetostratigraphy to chron C32n.1n between 71.4 and 71.64 Ma.

Crocodiles, by contrast, pursued a more amphibious …Their extinction was partially due to their competition with the mosasaurs, which were more agile and better adapted. Some experts think the pliosaurs disappeared because the Mosasaurs outcompeted them. This suggests they were not around when the Cretaceous-Paleogene extinction event occurred. This worldwide extinction event killed …Jul 31, 2011 · This mosasaur skeleton, belonged to Tylosaurus proriger, measures about 29 feet long and is on display at Sternberg Museum of Natural History in Kansas.
