His research interests included prehistoric cultural ecology, applications of pollen analysis in archaeology and research methodology.

Pollen research by Schoenwetter and his students involved a variety of sites in Mesoamerica, North America and Europe.He directed archaeological and botanical fieldwork in the Midwestern and Southwestern United States, California, Oaxaca, Zacatecas, Jalisco, England and France. Schoenwetter described this document collection as follows: "This collection of my unpublished professional writings has not been edited or changed from the form in which they were written between 19.Hopefully, the palynological and archaeological information they contain, and the concepts and methods presented in this collection of documents, will prove useful to others researching similar problems and situations.Readers should be warned, however, that these writings have not been subject to professional peer review.Patterns of occurrences of spore-pollen species in Neocomian–Aptian palynological assemblages are significant for characterizing Lower Cretaceous palynofloras.Varied environments of deposition are also reflected by the Neocomian–Aptian assemblages.

The Palynology and Earth Science Laboratories at GNS Science, Gracefield, are multipurpose laboratories designed for a wide range of sample preparation and analysis within a secure, safe and contaminant-free environment.

The primary function of these laboratories is to process rock and sediment samples for palynological analysis – the study of pollen, spores, dinoflagellate cysts and other microscopic organic material.

Using palaeofloristic differentiation, emphasis has been placed on first appearance datums (FADs) of key species in the palynological zonation scheme presented in this paper.

The basic data that have been analysed are from the subsurface Lower Cretaceous Rajmahal Formation in the Panagarh area, West Bengal.

The successive first appearances of the following taxa are the main criteria for identifying palynological zones: .

By Barremian–Aptian times maximum diversity of the palynomorph assemblages was attained, reflecting provincialism from west to east in India.
