This animal is known exclusively for an incomplete fossil, but sufficient to reconstruct (at least partially) its appearance.
Ohmdenia must have been a large fish, at least two and a half meters long.
Ohmdenia was therefore one of the largest bony fishes of the lower Jurassic, surpassed only by the great chondrostei such as Strongylosteus and Gyrosteus .
The body had to be relatively slender, with a symmetrical and slender tail.
The skull was long and short, and had a jaw equipped with numerous teethsmall, rather robust, rear-facing and placed in an area that extended along the dorsal margin of the jaw.
The combination of a long and slender body and a low and elongated skull is unique among the fish related to Ohmdenia (the pachicormiforms).
