Actiocyon parverratis

Actiocyon parverratis is an extinct small carnivoran of the red panda family Ailuridae and the second species of the genus Actiocyon, from the Middle Miocene of western North America. Paleontologists Smith, Czaplewski and Cifelli described it in 2016 from three specimens, with a lower jaw from the lowest section of the Monarch Mill Formation in Middlegate Basin, Nevada, as the holotype, and the name means small wanderer. It was smaller than Actiocyon leardi and much smaller than Simocyon, and it lived in a high altitude temperate forest, a mixed conifer and hardwood forest in north facing canyons at about 2,700 to 2,800 metres. A review of ailurid taxonomy in 2025 kept it as a valid species but called its place in the genus tentative.
