Natural History Museum Rotterdam - Specimens

Project name: Trinational Monarch Knowledge Network

Dataset summary : Specimen database of the Natural History Museum Rotterdam. The total collection is estimated to hold 373.200 specimens, of which around 85% are digitized at the specimen level and contained in this dataset. Arthropods (56%; mostly European) and molluscs (30%; worldwide recent specimens, fossil specimens from North-West Europe) make up the bulk of the collection. Chordates make up 9% of the collection and include a significant amount of fossil terrestrial and marine vertebrates from the Netherlands and the southern North Sea, while recent specimens predominantly originate from the Netherlands. Plants make up 5% of the collection and originate almost exclusively from the Netherlands. The collections of other taxonomic groups, e.g. Fungi and various marine invertebrates, are small, but do contain well documented interesting records.
