Fossils and Strata is an international series of monographs and memoirs in palaeontology and biostratigraphy, owned by, and published on behalf of, The Lethaia Foundation in cooperation between the Scandinavian countries.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.

Part of a monograph series on fossilsThe publication,New Middle and Late Anisian (Middle Triassic) Ammonoid Faunas from Northwestern Nevada - Taxonomy and Biochronology details proceedings from the Fifth International Brachiopod Congress in Copenhagen, Denmark in 2005. Congress topics included various aspects of the study of brachiopods.

The highly fossiliferous succession of Smithian (Early Triassic) ammonoids from northwestern Guangxi (South China) provides a key equatorial record, at the boundary between Tethys and Panthalassa. After the end-Permian extinction, ammonoids reached their first major diversity peak during Smithian times, coupled with a marked contrast in their latitudinal distribution. This monograph contains a part of the fundamental taxonomic and biostratigraphic data of a more comprehensive research project addressing patterns of recovery in time and space of Early Triassic ammonoids and other marine clades, in conjunction with global paleoceanographic and paleoclimatic changes.
