The palaeontology and biostratigraphy collections are split between Keyworth and Edinburgh, with the former holding most of the English and Welsh material, and the latter the majority of the Scottish material. Most of the type, figured and cited material is stored centrally at Keyworth.
Type & Stratigraphic Collection. All type, figured and cited macrofossils, plus other museum quality material selected for its stratigraphical importance. There are about 200000 specimens in Keyworth and about 5000 in Edinburgh. They are a useful starting point for many palaeontological studies.
Survey Collection. Material collected by Survey officers for biostratigraphic study. There are about 1250000 specimens in Keyworth and 400 000 in Edinburgh.
Micropalaeontology Collection. Includes type, figured and cited material. There are about 240000 slides in Keyworth and 6450 in Edinburgh.
Donated collections, including the important John Smith Collection in Edinburgh.
