Special Papers in Palaeontology, Graptolites from the Upper Ordovician and Lower Silurian of Jordan

Special Papers in Palaeontology, published by The Palaeontological Association, is a series of substantial separate works conforming to the style of the Palaeontology journal. Two issues are published each year and feature high standard illustrations. 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. 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. Brings together researchers, geologists and enthusiasts who continue to find material of significance. Includes 2 plates and 22 text-figures.
