The genus was identified in 2023 from fossilized teeth found in the Ste. Genevieve Formation rock layer at Mammoth Cave National Park in Kentucky, the United States.[1] The distinctive teeth, arranged in a fan-like structure, featured a large tooth in the center and three smaller teeth alongside it. Each tooth had a rounded curved cusp for clipping and grasping hard shell prey, with ridges on the inner side for crushing.[2][3]
