Ankalagon saurognathus

Ankalagon saurognathus is an extinct carnivorous mammal of the family Mesonychidae, endemic to North America during the Paleocene epoch (63.3—60.2 mya), existing for approximately 3.1 million years. Known from the Paleocene Nacimiento Formation of New Mexico, Ankalagon is the largest mesonychid known from the Paleocene of North America, and it provides the best evidence for sexual dimorphism in mesonychids.
