Analyses of distribution and occurrences of both trilobites and brachiopods have been pivotal for the current understanding of Lower Palaeozoic biogeography. A fruitful coupling with palaeomagnetic studies has recently produced highly accurate palaeomaps for the Ordovician and Silurian. Tergomyan molluscs and gastropods represent abundant and diverse marine benthos with a huge potential for further detailing of Lower Palaeozoic biogeography. In the present project we aim at analysis of Ordovican – Devonian members of these groups, on a stage by stage level. The analysis will be at the generic level, because very few species seem to be common between the various palaeo terranes. This is especially true for the Ordovician. Although a number of important contributions on diversity and distribution exist, these molluscs have never been subjected to a large-scale numerical analysis. In the literature, Ordovican taxa such as Peelerophon (Tergomya), Tritonophon (Gastropoda), and the widespread macluritid gastropods have been recognized as useful for biogeographical studies. For Silurian, and particularly Devonian taxa, a much better understanding of biogoeographical distribution exists. Devonian gastropods have for instance been used to formalize distinct biogeographical realms. The current project involves several experts, with the two authors as principal coordinators.
