LUND COLLECTION The Peter Wilhelm Lund Collection is a large and important Late Pleistocene collection of subfossil bone remains, primarily consisting of mammal bones from Minas Gerais, Brazil. Unearthed from limestone caves, the collection includes more than 50 mammalian type-specimens. The collection that today resides in the Zoological Museum, part of the Natural History Museum of Denmark is now being reexamined, digitalized and repacked. During this process, the most spectacular specimens have been reviewed and several forgotten specimens have been rediscovered. Also, in preparation for the future, newly discovered hair samples and coprolites are being evaluated for potential ancient DNA retrieval. he Danish naturalist Peter Wilhelm Lund (1801- 1880) is famous for having explored more than 800 ISTORY H limestone caves near the village of Lagoa Santa in K the Brazilian State of Minas Gerais. In 60 of these USEUM OF ATURAL ATURAL caves he discovered substantial amounts of subfossil, Late ENMAR T N M D Pleistocene bones, mainly from mammals. P.W. Lund was very diligent and thorough while working with the many bones and bone fragments from the caves, and he managed to identify more than 100 extinct species of mammals. Many of the species were new to science, such as the saber-toothed cat Smilodon populator and numerous types of ground sloths, all of which Lund was the first to describe and name. Very fittingly, P.W. Lund is often described as “The Father of Brazilian Paleontology”. P.W. Lund’s scientific results were written down and sent home to Denmark as a series of articles on Brazil’s prehistoric fauna (Blik på Brasiliens Dyreverden før sidste Jordomvæltning, 1837-1846). In 1845 he donated his entire collection to King Christian the 8th of Denmark and today the collection is an important and integral part of the Quaternary Zoology Collections at the Natural History Museum of Denmark.

ASPER HANSEN K THE NEW MUSEUM AND THE FUTURE OF THE P.W. LUND COLLECTION In 2004 the Natural History Museum of Denmark was created by merging the Botanical Gardens, the Botanical Museum, the Zoological Museum, and the Geological Museum - all parts of the Copenhagen University, Denmark (www.snm.ku.dk). It is the ambition to build a new joint “mega-museum” in The broken breccia with mammalian hairs sticking out. the Botanical Gardens within the next 6-7 years, depending on funding.
