They were not sea dinosaurs, but a separate group of reptiles, more closely related to modern snakes and lizards, according to the Philip J. Currie Dinosaur Museum. Mosasaurs went extinct 65.5 million years ago in the same mass extinction event that wiped out the dinosaurs, Live Science previously reported.
Was the mosasaurus the biggest dinosaur?
That said, the real Mosasaurus was indeed a large animal, with the biggest specimen known estimated to be around 17 meters or 56 feet long (Grigoriev, 2014). This makes it one of the largest, if not the largest, members of the mosasaurid family alongside other big species like the 14 meter North American Tylosaurus.
Why did the mosasaurus die?
About 92 million years ago, an extinction event occurred that was caused by large-scale underwater volcanic activity. It wiped out several groups of animals in the seas, among these were the ichthyosaurs or “fish lizards”, and the pliosaurs, large-headed and more predatory cousins of the plesiosaurs.
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 killed the Megalodon?
Extinction of a mega shark
The cooling of the planet may have contributed to the extinction of the megalodon in a number of ways. As the adult sharks were dependent on tropical waters, the drop in ocean temperatures likely resulted in a significant loss of habitat.
Is mosasaurus bigger than 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. So It was around 14.2-15.3 meters long, and possibly weighing 30 tons. Mosasaurus was longer than Megalodon so yeah.
