Ohmdenia multidentata was named by Hauff (1953). Its type specimen is GPIT 1017/1, a partial skeleton (Disrupted skeleton missing portions of the anal and dorsal fins, skull roof and braincase. The left mandible was found approximately 1.5 m from the skeleton and), and it is a 3D body fossil. Its type locality is Ohmden, GPIT specimen, epsilon III, which is in a Toarcian marine shale in the Posidonia Shale Formation of Germany. It is the type species of Ohmdenia.
