A big sea monster from the period of the dinosaurs has been found and named after a Norse snake.
The 24-foot-long creature is a brand new species of mosasaur—aquatic, carnivorous lizards that lived throughout the late Cretaceous interval. The fossil was found in North Dakota in 2015, and is described in a brand new examine revealed within the Bulletin of the American Museum of Natural History.
Paleontologists found the “spectacular specimen” consisting of a close to utterly intact cranium jaws, cervical backbone in addition to some vertebrae.

“If you set flippers on a Komodo dragon and made it actually huge, that is principally what it might have seemed like,” examine lead creator Amelia Zietlow, a Ph.D. pupil in comparative biology on the American Museum of Natural History’s Richard Gilder Graduate School, stated in a launch detailing the findings.
Scientists named the brand new species Jormungandr after a sea monster from Norse mythology. In tales, the massive legendary creature is often known as the Midgard Serpent or World Serpent, and is claimed to dwell in a sea encircling Earth.
Mosasaur had been first found over 200 years in the past. Its discovery predates what we all know concerning the dinosaurs. But scientists nonetheless have many questions on the species, together with how and once they developed to change into totally aquatic.
Paleontologists are additionally attempting to find out how completely different teams of mosasaur are associated to one another. This new discovery offers them with new perception into the species.
“This fossil is coming from a geologic time within the United States that we do not actually perceive,” co-author Clint Boyd, from the North Dakota Geological Survey, stated within the launch. “The extra we will fill within the geographic and temporal timeline, the higher we will perceive these creatures.”
The new fossil appeared to have a shark-like tail and a bony ridge on the cranium.
After nearer evaluation of the specimen, scientists decided that it shares options with two other forms of mosasaurs—the Clidastes, a smaller form of mosasaur, and the Mosasaurus, which grew to almost 50-foot lengthy and lived throughout the time of the notorious Tyrannosaurus rex.
Paleontologists imagine that the Jormungandr would have lived earlier than the time of the Mosasaurus, round 80 million years in the past.
“As these animals developed into these large sea monsters, they had been consistently making modifications,” Zietlow stated within the launch. “This work will get us one step nearer to understanding how all these completely different types are associated to at least one one other.”
