Title Scan A: Protasterina flexuosa (CMC 25001)
Downloaded 1 time
Description Micro-CT scan of Protasterina flexuosa (CMC 25001) using the North Star Imaging micro-CT scanner housed at Vanderbilt University (Tennessee, USA). 1170 two-dimensional images were generated with a voxel size of 29.3 microns at a voltage of 100kV and current of 62 microamps. Volume was reconstructed using EFX-CT. Users should contact authors prior to file use other than corroborating data presented in paper.
