These files comprise lists of neogastropod species from the Early Cenozoic of Seymour Island, Antarctica and tropical counterparts in both the US Gulf Coast and Paris Basin. They comprise a key part of the raw data analysed in the paper Crame et al. (2018). For each of these three localities species are listed in taxonomic order, following conventional taxonomic notation. Faunas are listed for the Paleocene, Early Eocene and Middle Eocene time intervals for the two tropical localities, but only for the Paleocene and Middle Eocene of Antarctica. The accurate location of all the localities is given in a series of published papers. The Seymour Island samples were collected across three field seasons; 1999, 2006 and 2010. The US Gulf Coast and Paris Basin data were constructed from existing literature. Funding was provided by the NERC grants NE/I005803/1 and NE/C506399/1.

Despite the important tectonic and stratigraphic setting, rocks from the English Coast area remain largely unstudied, as the paucity of exposure has hindered detailed structural and sedimentological analysis. Samples were collected for zircon analysis following a traverse starting at the English Coast and ending at Sky-Blu. A total of around 250kg of rock were collected and rocks at Fitzgerald Bluffs were revisited and sampled for the first time in 25 years. Highlights included the recognition of a previously undiscovered granitoid body and the discovery of fossils that tentatively indicate that Permian rocks are more widespread in the region.

A new technique that coupled SHRIMP (Sensitive High Resolution Ion Microprobe) U-Pb analyses with Laser ablation ICP isotope analyses for detrital zircons enabled the provenance of sediments from the English Coast region to be better assessed than had been previously possible. Such analyses, combined with Sm-Nd, Sr and Pb analyses for the sediments and plutonic rocks that cut the sediments, enabled a better assessment of the affinity of the English Coast rocks.

Geological station and sample registers related to rock samples collected from eastern Ellsworth Land during the 2002-2003 field season. In addition, processed data related to zircon mineral analysis using a technique that combines measurement of the U-Pb and Lu-Hf isotope systems. Minerals found in sediments that are resistant to earth surface processes, such as weathering and erosion, can yield information including the age and geological evolution of the sediment source region. Such a fingerprint is often unique and can be put in geographical context allowing an evaluation as to whether rock units today found adjacent to each other were originally deposited close to each other or not. Ultimately through rigorous zircon provenance analysis a new model for the crustal makeup of the Antarctic Peninsula can be tested.

The palaeontology collection at the British Antarctic Survey is a unique and internationally important collection of specimens sourced predominantly from the Antarctic Peninsula and Scotia Arc. The collection was started in the 1940s and continues to be added to frequently through ongoing BAS research. Its importance lies not only in the fact that it is globally one of the main reference collections of Antarctic palaeontological material, but also in its high proportion of Mesozoic flora and fauna which can be used to understand evolutionary dynamics, continental movements and climatic changes over the past 250 ma. In addition to molluscs and other major animal phyla, the collection is particularly strong in plant material, ranging from fossilised wood and exceptionally preserved leaves to pollen and spores. Given the logistical challenges of sampling material from the Antarctic continent, this collection represents a wealth of taxa which were previously unknown to science and consequently houses a high number of taxonomic types. A project is underway to digitally catalogue the BAS Type and Figured fossil collection and make the data easily accessible to researchers worldwide. Currently the data from over 2000 fossil specimens are available online, together with high resolution photographs. Over the next year further specimens, including palynological samples, will be added to the database and photographs will be made available of the entire collection.

The British Antarctic Survey holds one of the most extensive collections of Antarctic rocks and fossils anywhere in the world. These are predominately from the Antarctic Peninsula region and Scotia Arc, although there is also important material from areas such as the Ellsworth Mountains, Marie Byrd Land and the Transantarctic Mountains. Some of these specimens go back to the very earliest days of the Falkland Islands Dependencies Survey in the 1940s, and include collections made by the pioneer geologists at bases such as Hope Bay and Deception Island. Right from the outset, every specimen collected in Antarctica has been numbered and catalogued, and a vast reference archive is now available for use by the geoscience community. We currently have information relating to 150,000 field samples often with associated analysis data such as geochemistry. Additionally we hold a variety of data for nearly 500 marine cores. Metadata and data are stored digitally within a number of Oracle 10g database tables and for some datasets such as the type and figured fossil collection there is external access through a web interface. However, a significant number of datasets exist only in analog form and are held within the BAS archives organised by individual geologist. This abstract acts as an overview of the BAS geological data - both terrestrial and marine.
