New Zealand Permian brachiopod systematics, zonation, and paleoecology

Sixty-five brachiopod species and subspecies from the New Zealand Permian are described or revised. World correlations are summarized and a method is proposed for analysing relative diversities within sequences to detect episodic changes in brachiopod diversities that probably reflected climatic changes, against a background of changes in lithotope and water depth. Several parameters that affected the distribution and nature of New Zealand Permian brachiopod communities are discussed.-from Autho
