Lethaia

Aims & Scope

Lethaia is a quarterly open access journal that publishes articles of international interest in the fields of palaeontology and stratigraphy.

Articles concentrate on the development of new ideas and methods, and on descriptions of new features of wide significance.

Palaeobiology, integrating the study of fossil organisms with modern biology, and palaeoecology are core topics of the journal.

Biostratigraphy, analysing the relative timing and correlation of biological and environmental events, is another.

Information on fossil organisms should be of general interest to palaeontologists, biologists and stratigraphers.

Lethaia does not normally publish systematic palaeontology, except were this is of exceptional significance, dealing with the higher units on which our concepts of phylogeny and classification are based.

Articles on stratigraphy should meet the same requirements for general interest and deal with stratigraphical principles, correlations of at least continent-wide importance, new occurrences or revisions that establish major features in palaeogeography, etc.

In addition to articles, Lethaia contains shorter communications (Lethaia Focus), and reviews (Lethaia Reviews).

For systematic descriptions of taxa at lower level and more comprehensive texts, readers and potential authors are referred to Fossils and Strata, an international series of monographs and memoirs in palaeontology and biostratigraphy, complementing Lethaia.
