Micropaleontology is published with six issues per year containing peer-reviewed research on systematics, morphology, biology and ecology of animal, plant, and protist microfossils and their living representatives.
Stratigraphy is published online four times a year with optional printed copies. Subject area ranges across the the entire range of stratigraphic disciplines, with emphasis on applications of micropaleontology.
The Catalogues reproduce the complete type descriptions for genus- and species-level taxa, including full-size reproduction of original figures and charts.
