Middle Devonian goniatites from the Buchan District, Victoria

Abstract

following goniatites are described: Bactrites howitti n.sp., Bactrites sp. ind., Lobobactrites inopinatus, n.sp., Lobobactrites sp. ind., Gyroceratites desideratus n.sp., and an indeterminate anarcestid. The fauna forms three distinct assemblages which are all closely related in age and indicate early middle Devonian. It is the first goniatite fauna of this age to be described from the Australasian region.
