This issue investigates the forty-two graptoloid graptolite species which are described from the upper Hirnantian persculptus Biozone, lower Rhuddanian ascensus-acuminatus and vesiculosus biozones and Aeronian of Jordan. The book studies the recent interest in modelling the deposition of the organic-rich shales of latest Ordovician and early Silurian age in Jordan which has led to the collection of a considerable number of graptolites.
