Mosasaurs were effective predators due to their streamlined bodies, strong limbs adapted into flippers, and powerful tails, which allowed them to swim swiftly and maneuver easily in the water. Their sharp, conical teeth were designed for gripping slippery prey, such as fish and other marine reptiles. Additionally, their keen sense of sight and possibly acute hearing would have helped them locate and ambush prey in diverse aquatic environments. Overall, these adaptations made mosasaurs formidable hunters in their prehistoric oceans.
Mosasaurs
70 million years ago
Yes, the closest living relatives of mosasaurs are modern-day reptiles, particularly snakes and monitor lizards. Both groups belong to the order Squamata, which shares a common ancestor with mosasaurs. While mosasaurs were marine reptiles that thrived during the Late Cretaceous period, their lineage has since evolved into the reptiles we see today.
Giant Mosasaurs ate and killed them.
They lived in the Late-Triassic and the Cretaceous, but disappeared through the Jurassic!
Certain kinds of sharks and maybe killer whales do, and in the past, mosasaurs and plesiosaurs did.
An Aigialosaurus specimen was found with eggs developing inside of it. This is proof that mosasaurs did give birth to live young, which developed in eggs that the mother held in her body. Pliosaurs, also known as short necked plesiosaurs, also gave birth to live young.
They include Ankylosaurs (the armored dinosaurs), Mosasaurs, and Plesiosaurs (both marine reptilian groups).
Mosasaurs were apex predators that primarily ate fish, squids, turtles, and other marine reptiles. Some species were known to feed on smaller mosasaurs as well. Their diet varied depending on their size and the environment they lived in.
First of all there is no proof that mosasaurs existed so if they did exist, then no they would be dead due to change of water temperatures
No. Plesiosaurs were marine reptiles, not dinosaurs. Saurichians were one of the two main groups of dinosaurs (which included sauropods - such as Apatosaurus - and theropods - such as T. rex).
There were no ocean dwelling dinosaurs. Large marine reptiles that are often thought of as dinosaurs include plesiosaurs, pliosaurs, mosasaurs, and icthyosaurs.
