Edops

Edops ('swollen face') is an extinct genus of temnospondyl amphibian from the Late Carboniferous - Early Permian periods.

Edopoids also had particularly big premaxillae (the bones that form the tip of the snout) and proportionally small external nostrils.

Within the clade, the most basal member seems to be Edops from the Early Permian Archer City Formation of the US, a broad-skulled animal with large palatal teeth.

[2] The American paleontologist Alfred Sherwood Romer named Edops "swollen face" (from Greek oidos "swelling" and Greek ops "face") in 1936, noting that the "premaxillaries are greatly thickened and produced externally into rounded swellings (whence the generic name).

In a 1943 popular article, Romer explained that the original fossil find was nicknamed "Grandpa Bumps" for the lumps of bone, which had survived while the rest of the first skull had been largely destroyed.
