Are Mosasaurs More Closely Related To Marine Iguanas?

Will marine iguanas evolve into mosasaurus? They didn’t. They evolved in swamps or marshes from freshwater fish, as depicted in the artists’ scenarios below. So there is no “return to the sea,” because they never came from the sea in the first place.

What is the mosasaurus related to? Mosasaurs ARE NOT DINOSAURS. They are reptiles and are closely related to snakes and monitor lizards. Mosasaurs went extinct at the end of the Cretaceous during the end Cretaceous mass extinction event. The Tylosaurus mosasaur shown on the Jurassic Park movie was the largest mosasaur to exist.

What did mosasaurus evolve from? aigialosaurs
Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Earliest Late Cretaceous. During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators.

Scientists on Tuesday attributed their extinction 94 million years ago to the combination of global warming and their own failure to evolve swiftly enough. The study showed that large mosasaurs in fact appeared only after ichthyosaurs went extinct.

Can a mosasaurus kill a Megalodon?

While a similar length, the Megalodon had a much more robust body and huge jaws built for devouring whales and other large marine mammals. A Mosasaurus would not have been able to get its jaws around the much thicker body of the Megalodon. It would just take one catastrophic bite for the Megalodon to end the battle.

What can kill a mosasaurus?

Mosasaurus attacks Spinosaurus, but couldn’t land a hit until, he crush Spinosaurus onto the ocean floor and tosses him to the ice sheet above and crash into Spinosaurus. However, Spinosaurus uses the icicles above to kill Mosasaurus and was successful, thus killing Mosasaurus.

Are ichthyosaurs Diapsids?

Ichthyosaurs are superficially dolphin-like reptiles that were important marine predators from the Triassic Period through the middle of the Cretaceous Period.
For now, paleontologists think that ichthyosaurs are diapsids, but exactly where they fit in the diapsid tree is not yet known.

Was the mosasaurus bigger than the Megalodon?

People always say it’s 20.
4 meters, but in reality it’s around 18 meters and weigh 50, not 100 tons.
But according to a new study, it was smaller.

Is mosasaurus bigger than T Rex?

The Mosasaur Size Chart says that Mosasaurus is the largest mosasaur (like how I think), and compared to the T-Rex size, Mosasaurus is definitely bigger than both I-Rex and T-Rex.
I think that it reached 16-18 meters (That’s about 55-60 feet, bigger than Spinosaurus, I-Rex, and T-Rex.
