Database contains specimen records from the Mammalia collection of the Naturalis Biodiversity Center (Leiden, Netherlands). The zoological specimens come from the National Museum of Natural History (RMNH; Rijksmuseum voor Natuurlijke Historie), later National Museum of Natural History, Naturalis in Leiden and the Zoological Museum Amsterdam (ZMA) and new acquisitions. This database replaces the dataset "Zoological Museum Amsterdam, University of Amsterdam (NL) – Mammalia" which was hosted earlier on the GBIF dataportal and contains many new and updated records, especially from the RMNH collection. The old registration numbers of the former institutions (RMNH, ZMA) are also mentioned in the dataset.
