TL;DR

Paleontologists have discovered a new species of mosasaur, a massive marine reptile that lived about 80 million years ago. Named Jormungandr walhallaensis after the Norse mythological sea serpent, the mosasaur had a unique combination of features that challenged classification. The fossil, found in North Dakota, includes a near-complete skull and provides valuable anatomical details for studying the evolutionary history of mosasaurs and their transition from land to sea. Further research and additional fossils may help determine the exact position of Jormungandr walhallaensis on the mosasaur family tree.
