Despite being somewhat similar in appearance, Pliosaurs and Mosasaurs were not closely related.
Pliosaurs were a group of marine reptiles belonging to a now-extinct order of reptiles called plesiosaurs. Their closest living relatives are turtles and tortoises.
Mosasaurs were a group of marine reptiles in the order Squamata, which also includes lizards and snakes.
Pliosaurs swam primarily using their flippers, in which the phalanges (finger and toe bones) were pressed together.
Mosasaurs had flippers as well, but the phalanges were spread apart. They likely propelled themselves though the water with their tails, which where longer and more flexible than those of pliosaurs.
pliosaur
Yes, of course the mosasaur was smart
Yes
T-Rex
It lived in Europe and north america.
Mosasaur fossils are the remains of large, extinct marine reptiles called mosasaurs that lived during the Late Cretaceous period. These fossils include teeth, bones, and sometimes even preserved soft tissues, providing valuable information about the biology and evolution of these creatures. Some notable mosasaur species include Mosasaurus and Tylosaurus.
A large Pliosaur is the only confirmed creature.
mosaur vs megaldon
Liopleurodon was a 20 to 35 ft pliosaur (short necked plesiosaur). They were apex predators in the seas surrounding the islands of Europe. They existed between 160 and 150 million years ago.
The Hainosaurus at up to 17 meters (57 feet) long
Tylosaurus was not a dinosaur. It was a type of mosasaur, which were large, carnivorous marine reptiles.
