Journal of Systematic Palaeontology

Aims & Scope

The Journal of Systematic Palaeontology publishes papers that provide novel and impactful results in phylogenetics and systematics and that use these results in ways that significantly advance rigorous analyses of palaeogeography, palaeobiology, functional morphology, palaeoecology or biostratigraphy.

Papers dealing with theoretical issues or molecular phylogenetics are also considered if they are of relevance to palaeo-systematists.

Contributions that include substantial anatomical descriptions, descriptions of new taxa or taxonomic revisions are welcome, but must also include a substantial systematics component, such as a new phylogeny or a revised higher-level classification.

Papers dealing primarily with alpha-taxonomic descriptions, the presentation of new faunal/floristic records or minor revisions to species- or genus-level classifications do not fall within the remit of the journal.
