PALAIOS publishes in US-style English only. Non-native English speakers must have their manuscripts critiqued by an English speaker prior to submission.

Supplemental files are permitted and must be submitted with articles. Upon acceptance, files will be uploaded to the SEPM website. Supplemental data files must be in spreadsheet formats so data are easily accessible.

PALAIOS does not publish papers dealing largely or exclusively with systematic paleontology, but the inclusion (in the main body of the paper or an appendix) of a section formally establishing a single taxon or a very limited number of taxa is allowed, if underpinning the other content of the paper.

All Research Articles are peer reviewed.
