Rhynie chert Prototaxites taiti dataset

3D models of Prototaxites taiti from the 407 million year old Rhynie chert. Photogrammetry was used to capture the external 3D structure of two Rhynie chert blocks. Block North Sea Core (NSC) 36 and Lyon collection block 156. After describing the external surface of NSC36 we cut the specimen to investigate internal structure and produced another photogrammetry model of the cut specimen. Alongside our investigations with photogrammetry we produced a 3D model of complex tube branching within a medullary spot. This investigation was based on using confocal laser scanning microscopy to investigate thin section NMS G.2024.5.7 (MPEG0057). The dataset is related to the upcoming publication by Corentin C. Loron, Laura M. Cooper, Sean McMahon, Seán F. Jordan, Andrei V. Gromov, Matthew Humpage, Laetitia Pichevin, Hendrik Vondracek, Ruaridh Alexander, Edwin Rodriguez Dzul, Alexander T. Brasier, Alexander J. Hetherington. (In submission).
