Protopterus aethiopicus DICE microCT data for Mandibular musculature constrains brain-endocast disparity in sarcopterygians

The specimen was stained in IKI using the method of Metscher (2009) for three months. Micro-CT (uCT) scans were obtained using a Feinfocus 10-160kV transmission X-ray source and a Perkin Elmer XRD0822 1 MP flat panel X-ray camera. The peak energy used was 120kV, and 2 second exposures were corrected with offset and gain images. The resulting exposures were reconstructed as a tif stack using OctopusV9 resulting in a voxel size of 87.3.
