Merycodus has had a confusing taxonomic history. The closely related Meryceros and Submeryceros are generally regarded as synonymous with Merycodus.[3][4] One described species known as Merycodus grandis has now been reclassified as a species of Prosynthetoceras.[5] Another former species, M. furcatus is now placed in Cosoryx.
Description
Merycodus had relatively short horn shafts with tines of nearly equal size that were about as long as the shaft. Species traditionally included in Meryceros had horns that were generally larger and more laterally compressed.[3]
