Copecion was a genus of early herbivorous mammals that was part of the family Phenacodontidae.P. D. Gingerich. 1989. "New earliest Wasatchian mammalian fauna from the Eocene of northwestern Wyoming: composition and diversity in a rarely sampled high-floodplain assemblage". University of Michigan Papers on Paleontology 28:1-97. It reached 6 to 12 kg and was similar in size and morphology to Ectocion. Both these herbivorous ungulates likely occupied similar ecological niches.{{cite journal|author=Andrew Schwartz|date=November 2023|url=https://www.researchgate.net/publication/375634652|title=Investigating Niche Overlap in Two Sympatric Phenacodonts using Dental Microwear Texture Analysis|journal=83rd Annual Meeting Society of Vertebrate Paleontology at Cincinnati, Ohio}}
