Short summary
A new species of a group of extinct fishes with a worldwide distribution during the Cretaceous, about one hundred million years ago, is described. Motlayoichthys sergioi is an outstanding fossil fish from Mexico with unique characters within the Pachyrhizodontidae. This fish is part of a diverse fauna found in a limestone quarry in Central Mexico. The goal of this paper was to contribute to the knowledge of the family and to continue the study of the Muhi Quarry fish, endemic to Mexico.
