Fossils and Strata forms part of the same structured publishing programme as the international journal Lethaia and provides a complementary outlet for more comprehensive systematic and regional monographs, including taxonomic descriptions. Fossils and Strata also offers the publication of thematic special issues comprising a series of shorter contributions.
