This volume edited by Herbert Summesberger and William J. Kennedy contains two articles on the Coniacian and Santonian of the Gosau Group in Austria. The main article deals with the cephalopods of the Coniacian from the Gosau Group. Another article is dedicated to the genus Forresteria (Harleites), which was described for the first time from the Santonian of the Gosau Group from the Randograben (Rußbach am Pass Gschütt, Salzburg) and is a supplement to the Abhandlungen der Geologischen Bundesanstalt, volume 71, from 2017.
