Abstract

Harmostocrinus jonesi n. sp. (Mississippian: Chesterian) is described from the upper part of the Monteagle Limestone in northern Alabama, and is distinguished from all other species of the genus by bifurcation of the A-ray arm on IBr2 instead of IBr1. Reduction in overall number of arms, A-ray arm bifurcation, and reduction of cup-size demonstrate that H. jonesi is a paedomorphic evolutionary intermediate between the stratigraphically older Mississippian genus Abrotocrinus, and other, younger species of Harmostocrinus. Both peramorphosis (cup characters) and paedomorphosis (arm characters) were important factors in the evolution of Harmostocrinus jonesi.
