Type specimens may sit quietly in collections, but they’re central to naming, comparing and protecting biodiversity. This update highlights how dynamic and valuable museum collections really are.
A second addition to the herpetological type catalogue of the Zoological Museum of Hamburg at @leibnizlib.bsky.social, with 53 additional newly discovered or newly described type specimens: doi.org/10.3897/evol...
