Occlupanid ID Guide
The Holotypic Occlupanid Research Group classifies occlupanids by the shape of their oral groove. A sampling of standardized oral groove morphologies are presented here, in hopes of leading the enthusiastic occlupanologist towards a positive ID of their specimen. Note that some taxonomic families contain more than one shape of oral groove, such as in the wide diversity of the Archignathidae.
