Abstract

Scales, fin spine fragments, two symphysial tooth whorls, a dentigenous jaw bone fragment, and dentition cones of a new acanthodian species comprise the total acanthodian component from samples of the Jack Formation. The morphological variety of scales includes three normal body scale types, two specialized head scale types, pore scales and tesserae. The range of scale types, the shape of the fin spine fragments, and the form of the dental elements, indicate they are from a new species of ischnacanthid acanthodian. -Authors
