The ancient oceans hold secrets, and a new discovery unveils the tale of a massive, meat-eating marine reptile that roamed the seas 80 million years ago.

Paleontologists recently stumbled upon a unique specimen near the North Dakota town of Walhalla, leading to the christening of Jormungandr walhallaensis.

Though the creature itself had a less poetic name, the nickname Jormungandr connects to Norse mythology, much like Valhalla, the town's namesake.

The fossil's scientific name includes the town's reference to Norse myths and the Midgard Serpent, Jǫrmungandr.

The fossil is a treasure trove, including a near-complete skull, jaws, bony ridges, 11 ribs, and 12 vertebrae.

Jormungandr walhallaensis measured approximately 24 feet (7.3 meters) long, but it had unique features setting it apart from other mosasaurs.

Scientists faced a conundrum when classifying this newfound species, as it had a mix of characteristics from different mosasaur groups.

Additional fossils could help clarify its place in the evolutionary tree. The puzzling features raise questions about the animal's classification.

Bite marks on the vertebrae reveal a violent encounter, but was it an attack or scavenging? Future research will uncover the truth.

The story of Jormungandr walhallaensis adds to our understanding of mosasaurs, a diverse group of marine reptiles from the Cretaceous Period.

The world beneath the ancient seas remains a fascinating enigma, waiting to be unraveled as new fossils and detailed research shed light on prehistoric mysteries.
