1810s. Mitchell reported the discovery of mosasaur fossils in the Navesink Formation of New Jersey. These were the first North American mosasaur remains to be documented in the scientific literature.
Where was the first mosasaur fossil found?
Mosasaurs (from Latin Mosa meaning the ‘Meuse’, and Greek σαύρος sauros meaning ‘lizard’) comprise a group of extinct, large marine reptiles containing 40 genera in total. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764.
Where have mosasaurus bones been found?
The Maastrichtian is the epoch comprising the last 6 million years of the Cretaceous. Mosasaur fossils have been found all over the world including northern Europe, eastern Europe, Russia, Turkey, the Middle East, northern Africa, Canada, South America, the United States, and even on islands of coastal Antarctica.
How old is the mosasaurus fossil?
Mosasaur fossil: Life of 85-million-year-old ‘sea monster’ illuminated. Summary: One of the ocean’s most formidable marine predators, the mosasaur Platecarpus, lived in the Cretaceous Period some 85 million years ago and was thought to have swum like an eel.
How did the mosasaur go extinct?
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.
Is the mosasaurus bigger than the blue whale?
The largest estimates for Mosasaurus hoffmani put it at around 56 feet in length, about half the size of the largest blue whales on record. There’s no precedent for any predator alive being able to hunt down whales that size, but there aren’t many predators the size of a Mosasaurus either.
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.
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.
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.
Did dinosaurs have forked tongues?
When sedatives injected into the dinosaur kick in, the razor jaws close down on the tongue and sever it in a spurt of dark blood. But it’s unlikely that Allosaurus, Tyrannosaurus, or any other dinosaur had a prehensile, forked tongue.
Have they ever found a megalodon skeleton?
So far we’ve only found teeth and vertebrae of megalodons. Like other sharks, most of their skeleton is made from cartilage which doesn’t preserve well in the fossil record. … Scientists who have been studying modern sharks are working with paleontologists to study megalodon and other long-extinct shark species.
Is Megalodon extinct?
What if mosasaurus was still alive?
If it Mosasaurus still exist, our sonar technologys much more advanced than to day. Even poor countrys have much more advanced, feasable sonar teachnologys for fisherman and cargo ships. Geographical discoveries accur much more later than it is. Crossing oceans will very dangerous thing.
Is the Megalodon still alive?
Megalodon is NOT alive today, it went extinct around 3.5 million years ago.
