3D models of Ediacaran organisms generated using NURBS modelling for use in computer simulations of fluid flow. Models built between 2021 and 2023 using the computer-aided design program Rhinoceros 3D. File names refer to different fossil taxa and surfaces. STP files can be opened with most CAD software, including freely available programs such as Autodesk Fusion 360 and FreeCAD.

Reflectance transformation image of a cast (BGS fossil reference number GSM106161) of the holotype of Charniodiscus concentricus. The original fossil is the property of the Geology Department, University of Leicester, and the fossil is on display at New Walk Museum, Leicester

This dataset contains LiDAR scans as Faro Scene files of 53 scans which cover 15 different fossiliferous surfaces. The number of scans per surface varies depending on the topology of the bedding plane. These LiDAR scans were made in Newfoundland, Canada, from Mistaken Point Ecological Reserve (10 surfaces), Discovery Geopark (4 surfaces) and Ferryland (1 surface). 45 scans were made in July 2022 and 8 in September 2022. The scans were made in order to enable the mapping of fossil specimens within their communities so that spatial analyses can be used to infer the underlying biological and ecological processes than govern Ediacaran eco-evolutionary dynamics. The dataset is complete to reconstruct the bedding surfaces accurately.

Results files from computer simulations of fluid flow for 3D models of Ediacaran organisms and communities, generated using computational fluid dynamics. Simulations performed using the simulation software package COMSOL Multiphysics. Root folder names refer to initial trials ‘Cylinder Tests’), modern organisms (‘Chondrocladia lyra’), Ediacaran organisms (‘Pectinifrons’ and ‘Pterdinium’), and Ediacaran surfaces (‘Avalon’ and ‘White Sea’ surfaces). Sub-folder and file names refer to simulations performed with different models (e.g., ‘Base’, ‘Filled’ and ‘Flush’ Petridinium models), model orientations (e.g., 0°, 90°, and 180° to the inlet), current velocities (e.g., 0.15, 0.5 and 0.85 m/s), and turbulence models (e.g., Spalart Allmaras, shear stress transport, and large eddy simulation). Further details for Pectinifrons and Pteridinium available in Darroch et al. 2022 (https://doi.org/10.1017/pab.2022.2) and Darroch et al. 2023 (https://doi.org/10.1016/j.isci.2023.105989), respectively. Files can be opened with COMSOL Multiphysics (www.comsol.com) versions 5.6 or 6.0 and above.
