Ambystoma DICEmicroCT data for Mandibular musculature constrains brain-endocast disparity in sarcopterygians

DiceCT contrast staining was completed using a Lugol's Iodine (I2KI) solution. 11.75% Lugol's Iodine was prepared following the protocol of Gignac et al (2014) . Ambystoma was stained for 5 days prior to uCT scanning. The specimen was imaged using a Skyscan1173 (Bruker) desktop uCT scanner and were reconstructed as a stack of jpegs using NRecon 1.6.6. In both cases, the files were cropped in ImageJ (?to reduce file size and sampled images from the stack at an interval of 2 in the Z-plane. The resultant voxel size for Ambystoma is 16.69 x 16.69 x 33.38 microns.
