Paleontological Research

Aims & Scope

Paleonotological Research (PR) is a quarterly, peer-reviewed international journal, which focuses on original contributions primarily in the area of paleontology but also covering a wide range of allied sciences.

It has been published since 1997 as a successor to the former journal Transactions and Proceedings of the Palaeontological Society of Japan.

The emphasis of contributions will include global and local perspectives, and contents can cover all ages (Precambrian to the Quaternary, including the present time).
