Pachycormus

 Pachycormus is an extinct genus of fish from the Jurassic.

 Pachycormiformes is an extinct order of ray-finned fish known from Mesozoic deposits from Eurasia and the Americas. They were characterized by having serrated pectoral fins, reduced pelvic fins and a bony rostrum. Their relations with other fish are unclear.

 Some sources place Ichthyodectidae herein too, but these seem to be somewhat more advanced Teleostei.
