nhm_fossil_lithistids
This dataset presents the NHM Fossil Lithistida Collection in the Natural History Museum, London. This collection started to be built with the first fossil sponges from the Cretaceous of Wiltshire, collected by William Smith in 1816 and 1818 for the first geological map of England. The latest specimen to enter in the collection was collected from the Permo-Carboniferous of Norway by Angela Milner, a researcher at the Museum. Although they are mostly from the Cretaceous of England, lithistids are represented from the Cambrian to Cenozoic of England. This makes this collection key for studying this group.

生物分類学的範囲
This collection includes 406 taxa, of which there are 338 species and 15 varieties that are distributed mainly between tetralithistids, monalithistids, megalithistids, orchocladinids and spirosclerophorids. Tetralithistids are the most common, 44% of the collection, with representation in Central Europe, Ukraine, India, Republic of Trinidad and Tobago, and mainly in UK-England. The next most common are the monalithistids (32%) with representation in Central Europe and UK-England as well. In lesser proportion megalithistids (12%) represented in Central Europe, Libya, UK-England and USA. Orchocladids (8%) have been collected in Europe, UK and USA. Finally, the spirosclerophorids (1%) have been found in Europe and UK-Wales. 4% of the collection has not been possible to include in an order.
