Abstract
We present an interim Devonian bioregionalisation in which previous zoogeographical and biogeographical areas of Devonian taxa are reviewed. This review has been long overdue, as Devonian bioregionalisation has become poorly constrained since the foundational work of Arthur J. Boucot in the late 1960s. A systematic review of over 100 areas and amendments is completed for the first time with addition of three new areas: the Mardoowarra and the Late Devonian Eastern Australasia region, and Western Gondwana realm. This interim regionalisation is the first to be completed and standardised, made in preparation for future palaeobiogeographic studies and as a prelude to rigorous testing. By standardising the 1969 bioregionalisation of Boucot et al. Devonian biogeography can begin to assess if the proposed bioregionalisation is representative of true natural areas.
