"Jormungandr: The Giant Sea Dragon Unearthed in North Dakota"
Researchers have discovered a new species of mosasaur, named Jormungandr walhallaensis, which lived about 80 million years ago in the Western Interior Seaway. Measuring 24 feet long, Jormungandr is believed to bridge the gap between two iconic species of mosasaurs. The fossil specimen includes a nearly complete skull and various skeletal elements, providing valuable insights into the evolution and diversity of these ancient marine reptiles. The discovery expands the known range of mosasaurs and contributes to a better understanding of their relationships within the family tree.
