Contemporary palaeontological collections are usually taxon-based, which means that they contain information linked to the names of taxa. However, specimen-based databases (Berendsohn, 1995) may be more appropriate, since studies that are not linked directly to taxa should be less error-prone, allowing to avoid incorrect identifications of species made by previous investigators or changes in the taxonomic nomenclature. Specimen-based palaeontological databases should ideally contain not only digitized images of individual specimens but also descriptive detailed morphometric data obtained from these images. The descriptive information would allow to investigate a given taxonomic group with a set of diagnostic characters.
