    Computed tomography (CT) scans of extant and fossil chondrichthyans, of teeth organized into functional dentitions. These scans were taken on a Nikon Metrology HMX ST 225, in the Image and Analysis Centre, Natural History Museum, London.

    The map shows the localities of significant fossil samples, either collected by BGS Staff, or donated by individuals and institutions. The BGS fossil collections contain over 2 million specimens, including a sizeable quantity of type, figured and cited material. Since a small number of fossil locations are confidential, you are unable to view this dataset at large scales. However, if you send a data enquiry, such information may be made available. Enquiries are normally free, but a charge may be levied depending upon the time taken; users will be notified in advance. Material is available for inspection on application by e-mail. Specimens are sometimes available for loan to bona fide academics.

    The data are from X-ray tomographic analyses of tubular fossils. All scans were carried out using Synchrotron Radiation X-ray Tomographic Microscopy (SRXTM) except for specimen SMNH X 5324 which was also analysed using Ptychographic X-ray Computed Tomography (PXCT). The methods are described in the paper. The data consist of a stacked series of .tif files that represent maps of X-ray attenuation. The individual slices can be viewed with standard graphics software. The datasets can be studied in 3D using tomographic reconstruction software such as Avizo (www.vsg3d.com/), Spiers (www.spiers-software.org/), VG Studio Max (www.volumegraphics.com) etc. The voxel size, which is needed for scale calculations, varies between datasets and is given below. Some datasets consist of two 'blocks' of data, with slices named [specimen name]_B1 and [specimen name]_B2. These are placed in the same folder and follow on directly from one another. They can be opened together as a single dataset. The files relate to the following publication: Cunningham, J. A., Vargas, K., Liu, P., Belivanova, V., Marone, F., Martinez-Perez, C., Guizar-Sicairos, M., Holler, M., Bengtson, S. & Donoghue, P. C. J. 2015. Critical appraisal of tubular putative eumetazoans from the Ediacaran Weng'an Doushantuo biota. Proceedings of the Royal Society Series B: Biological Sciences.

    Laser scans of Ediacaran Fossil Surfaces. Data collected 2016-2018 in Newfoundland Canada using a laser-line probe. Data is in the form of .wrp files so can only be opened in Geomagic. The scan files are in files of the bedding plane. All scan numbers with the same base were scanned with the tripod in the same position, so no alignment is needed. Manuel alignment is needed between bases.

    Table S1.xlsx is Table S1, which contains 2D measurements of cell clusters used in Fig. 5 (this is also available from the publisher's website). The folders SMNH X 4447, SMNH X 5331 and SMNH X 5357 contain data from X-ray tomographic analyses of fossils figured in the paper: For SMNH X 5331 (the conical fossil that is the focus of the paper) there are two zip archives: 1. Slice data and Avizo files, containing: - Slice data: the raw scan data (.tif image stack) - Label files for cell clusters and individual cells: Avizo projects (.hx) containing the labels and the files required to open the project file. The cluster labels are based on a downsampled version of the data which is included here as slice data (.tif image stack). Voxel sizes for this file are 0.325 x 1.3 x 0.325 micrometers. 2. Working files, containing: - Surface models: .ply files for clusters and individual cells. - Segmented stacks: the label files as .tif stacks (voxel sizes as per slice data: 0.325 x 0.325 x 0.325 micrometres (cell labels); 0.325 x 1.3 x 0.325 micrometers (cluster labels)). SMNH X 4447 and SMNH X 5357 (two specimens figured for comparison) there is: - Slice data: zip archives of the raw scan data (.tif image stack). The individual slices (.tif images) can be viewed with standard graphics software, and the datasets can be studied in 3D using tomographic reconstruction software such as Avizo (www.vsg3d.com/), Spiers (www.spiers-software.org/), VG Studio Max (www.volumegraphics.com) etc. The Avizo project and label files (.hx and .am files) require Avizo software (www.vsg3d.com/) to be opened. The 3D models (.ply files) are widely compatible with 3D freeware packages such as MeshLab (http://meshlab.sourceforge.net/) or Blender (https://www.blender.org/), or with proprietary software, e.g. Avizo (www.vsg3d.com/), Geomagic (http://www.geomagic.com/en/), Mimics (http://biomedical.materialise.com/mimics).

    Data from the British Geological Survey's GeoIndex Collections theme are made available for viewing here. GeoIndex is a website that allows users to search for information about BGS data collections covering the UK and other areas world wide. Access is free, the interface is easy to use, and it has been developed to enable users to check coverage of different types of data and find out some background information about the data. More detailed information can be obtained by further enquiry via the web site: www.bgs.ac.uk/geoindex.

    Two datasets containing multiple diversity metrics of planktonic foraminifera. Recent data is from MARGO (Multiproxy approach for the reconstruction of the glacial ocean surface); Eocene data is from NEPTUNE (a relational database of microfossil occurrence records from DSDP and ODP publications), supplemented by literature searches. These data are related to Fenton et al (2016) Phil Trans (DOI: 10.1098/rstb.2015.0224) Data used in Fenton et al (2016) Environmental predictors of diversity in Recent planktonic foraminifera as recorded in marine sediments. The original data is from the MARGO database (Kucera, 2007)
