Pachyrhizodus is an extinct genus of ray-finned fish that lived during the Late Cretaceous in the Western Interior Seaway in North America and in Colombia, South America. The type species is P. basalis.[2] The species P. etayoi, described in 1997 by María Páramo from the La Frontera Formation in Colombia, was named honouring Colombian geologist and paleontologist Fernando Etayo.
