|Dinogorgon rubidgei model|
| †Dinogorgon rubidgei|
Like more derived rubidgeines, Dinogorgon has a number of massive bosses and rugosities on its skull, likely to reduce the stresses caused by struggling prey. Its snout was deep but narrow, similar to Aelurognathus but narrower than Rubidgea and Clelandina. It had 4-5 upper and lower postcanine teeth, which further distinguishes it from Rubidgea.
ClassificationDinogorgon shares many characteristics with Rubidgea and Clelandina, which has led some authors to synonymize them. All three are now considered to be part of the same tribe, Rubidgeini, rather than the same genus.
