A detailed look at the rhynchonelliformean brachiopods of Ireland This publication, Ordovician rhynchonelliformean brachiopods from Co. Waterford, SE Ireland: Palaeobiogeography of the Leinster Terrane, is Number 62 within the Fossils and Strata series. The international Fossils and Strata series features monographs in palaeontology and biostratigraphy with taxonomic descriptions. The series is owned by and published on behalf of The Lethaia Foundation in cooperation with the Scandinavian countries.

A Late Ordovician silicified brachiopod fauna from the White Mountain area, west-central Alaska is described and interpreted in a palaeoecological and biogeographical context. This area is situated within the Nixon Fork Subterrane of the Farewell Terrane, which origin and timing of final docking with Laurentia has been much debated. The current study adds new faunal data to the debate with nearly 100 species described, of these at least nine are new. The fauna is predominantly a deep-water autochthonous fauna that was mixed with an allochthonous fauna as a result of down-slope movement of turbidity currents. Biogeographically this study demonstrates close faunal affinities with Siberia.
