Neurankylus
Neurankylus is an extinct genus of turtles in the Testudines order that lived between 112-61 million years ago in Canada and the United States. It was originally placed within the monotypic family Neurankylidae, but it has since been placed in the Neurankylinae, alongside Trinitichelys. The type species, Neurankylus eximius, was described by Lawrence Lambe in 1902. The species N. lithographicus was discovered in the Milk River Formation, alongside the holotype of the pachycephalosaur Acrotholus.
