The inaccuracy of much of Osborn's composite reconstruction of ""Naosaurus"" was detailed by E.C. Case in 1914 with a revised description of "Edaphosaurus" based on additional fossil material, including large parts of a skeleton with limb bones and a crushed skull, which Case had discovered in Archer County, Texas, in 1912 and brought to the University of Michigan. His reconstruction of "Edaphosaurus cruciger", as shown in a drawing, had a much smaller head (with teeth for crushing mollusks or plants), more robust limbs, and a somewhat longer tail than Osborn's carnivorous ""Naosaurus"" mount. Case also confirmed that "Edaphosaurus" was the valid name rather than ""Naosaurus"". Despite his corrections, the name ""Naosaurus"", and even the outdated and incorrect "Dimetrodon"-like head, continued to appear in some popular sources.
