Papers in Palaeontology《古生物学论丛》（双月刊）. Papers in Palaeontology includes papers that document the diversity of past life and its distribution in time and space. As a sister publication to Palaeontology, its focus is on descriptive research, including descriptions of new taxa, systematic revisions of higher taxa, detailed palaeoecological, biostratigraphical and biogeographical documentation, and descriptions of significant floras and faunas from specific localities or regions. Submissions to Papers in Palaeontology should consider the broader implications and present the key questions and conclusions of the work in a wider context. In general, descriptions of single taxa, or local case studies which are primarily of interest to taxonomic or regional specialists, are likely to be too narrow in scope to be considered for the journal.

The Pan-Pacific Entomologist《泛太平洋昆虫学家》（季刊）.

The journal serves as a refereed publication outlet and accepts manuscripts on all aspects of the biosystematics of insects and closely related arthropods, especially articles dealing with their taxonomy, biology, behavior, ecology, life history, biogeography and distribution. Membership in the Pacific Coast Entomological Society includes subscription to The Pan-Pacific Entomologist, and Society Proceedings typically appear in the October issue of each volume.

PalZ《古生物学杂志》（季刊）. The Paläontologische Zeitschrift is the official publication of the Paläontologische Gesellschaft (German Palaeontological Association) and as thus aims to promote all aspects of the science of Palaeontology. The journal welcomes papers on all aspects of palaeontology, including Palaeozoology, Palaeobotany, Palaeoecology, Palaeogeography, Geobiology, theoretical and methodological aspects of palaeontological research, and contributions from related fields (e.g. biology) if relevant to palaeontology. Both high quality original research papers and review articles are welcome. Topical volumes presenting a collection of papers on a specific topic can also be proposed.

Palynology《孢粉学》（季刊）. Palynology was first published in 1977, and is now is a well-established, international journal covering all aspects of the science of organic microfossils and their modern counterparts. We accept papers on both pre-Quaternary and Quaternary palynology, and palaeobotany. Articles across the entire range of palynomorph groups and geological ages are welcomed. Contributions on both the traditional aspects of the subject, and the more novel uses of palynology, are all actively encouraged.
