CHITINOS is a microfossil image and data acquisition system developed to support palynologists from field work to report production. The system is intended for chitinozoans, but it can also accommodate other fossil groups. Thanks to its client-server architecture, the system can be accessed by multiple users. The database can be filled with data acquired during palynological work or taken from the literature. The system allows for the easy input, update, management, analysis and retrieval of paleontological data to enable the paleontologist to elucidate paleogeographic patterns, changes in biodiversity and taxonomic differentiations. Query and plot interfaces are intended for report production. The system was designed as the basis of a knowledge expert system by providing a new perspective in the interpretation of interrelated data.
