This is a Paleobiology Database Online Systematics Archive that includes all known published systematic statements regarding pinnipeds. This archive also contains every known published occurrence of fossil Pinnipedimorpha. If any known published account of a fossil pinniped seems to be missing from this archive, please contact the author using the information below, and report the missing occurrence, along with the relevant bibliographic information.

This archive aims to compile all information about the identity and distribution of fossil pinniped taxa to facilitate any and all other studies regarding fossil Pinnipedimorpha. The goal of this compilation is to contribute to a comparison to a study the distribution of Cenozoic marine tetrapods over time. This study is in progress. All of the data are publicly available for use by anyone.

Entry of these data began in 2000 and is an ongoing process. New publications on pinniped taxonomy are entered as soon as the author is made aware of them. Please note that there are significant disagreements about the proper taxonomic arrangement of pinnipeds. The taxonomy presented here reflects the most up to date ideas based on publication dates of references.
