Description

The fish is only known from an incomplete fossil, but it is good enough proof to know what it looked like. Ohmdenia was a large animal, averaging two and a half meters long. The body is long and thick. It had a wide mouth and a long and short skull.

Taxonomy

Ohmdenia is a member of the family Pachycormidae in the order Pachycormiformes. For a long time, Ohmdenia was considered a close relative of Birgeria, a famous Triassic predator. Further studies show that this is not the case, so they placed it in the extinct order Pachycormiformes.
