The Museum has a strong tradition of foraminifera research dating back to the late 1800s.
As a result, the foraminifera collection - with approximately 250,000 slides - is the most extensive of our micropalaeontological collections.
Specimens Major collections
The collections consist of both fossil and recent (living) specimens and contains a number of important sub-collections:
- HMS Challenger collection
- Former British Petroleum micropalaeontology collection
- Former Aberystwyth Microfossil Collection
- Former Iraq Petroleum Company collection
- Henry Buckley collection
- Heron-Allen slide collection
HMS Challenger collection
The HMS Challenger expedition (1872-1876) collected vast amounts of oceanographic data. The resulting collection is of historical and taxonomic importance for studying foraminifera.
The collection includes original samples dating back to the early period of the Industrial Revolution, providing a valuable resource for current and future research.
Former British Petroleum micropalaeontology collection
Contains the microfossil well-run samples from British Petroleum's exploration activities since the 1 1D0A 950s, including slides and residues from over 3,800 well and outcrop localities worldwide. The collection covers more than 120 countries.
The collection includes:
- micropalaeontological slides
- palynological slides (c. 78,000)
- nannofossil slides
- faunal slides
- loose specimens
- the former British Petroleum microfossil reference collection (foraminifera and ostracoda)
Former Aberystwyth Microfossil Collection
The collection includes:
- a wide variety of studies covering many geological periods
- older studies of contemporary foraminifera assemblage
These provide a unique opportunity to revisit numerous settings and evaluate changes in foraminifera abundance and diversity over time.
Former Iraq Petroleum Company collection
The former Iraq Petroleum Company (IPC) collection contains benthic foraminifera from the Middle East, covering the Palaeozoic, Mesozoic and Cenozoic eras.
The collection is particularly important for reconstructing environmental change and the geological history of the area.
The collections cover
- Saudi Arabia
- United Arab Emirates
Henry Buckley collection
The Henry Buckley collection of planktonic foraminifera contains material from around the world, and is a valuable resource for studying the effects of global change on recent foraminifera.
The collection contains 1,665 slides from 203 samples, as well as thin sections of ocean bottom deposits and sample washings from sample locations corresponding to the slide collection. It also contains approximately 10,000 scanning electron microscope micrographs.
Heron-Allen slide collection
The vast Heron-Allen collection contains 740 slides of foraminifera, including specimens from historic expeditions such as HMS Challenger and Terra Nova. A complete catalogue of the collection is available as an Excel spreadsheet.
The collection includes specimens from around the globe, collected between 1873 and the 1930s. Many notable research expeditions are represented, including:
- HMS Challenger
- Discovery I and II
- Terra Nova
- William Scoresby
