Ostracods from the Domerian and Toarcian of England
£1.00
Marine ostracods from the Middle and Upper Lias are described and their lateral and vertical distribution along the strike from the Dorset to Yorkshire coasts analysed. The composition of the assemblages and the affinities and occurrence of the species are examined, and two new species are described. Ostracod diversity apparently decreased throughout the Margaritatus Zone and few ostracods have yet been found in the Spinatum Zone. However, the Toarcian transgression brought in a new ostracod fauna of Middle Jurassic aspect.
