MicroCT Scans of a Carboniferous Tetrapod Jaw

5677 transverse DICOM slices capture the left lower jaw of the Carboniferous stem tetrapod Crassigyrinus scoticus. The data was collected by Laura Porro and Jennifer Clack in February 2013 at the Natural History Museum's Imaging and Analysis Centre for anatomical and biomechanical study.

Use Cases

• Segment and reconstruct 3D jaw anatomy from 5677 transverse DICOM slices for morphological analysis
• Compare voxel resolution (0.1271 mm/voxel and 0.1099 mm/voxel) across the anterior, middle, and posterior jaw parts
• Perform biomechanical simulations using the three-part scan data of the Crassigyrinus scoticus specimen

Strengths

• High-resolution scans with voxel sizes of 0.1271 mm and 0.1099 mm
• 5677 total transverse slices providing detailed internal structure
• Scans performed on a Nikon XH 225 microCT scanner at a professional imaging center

Limitations

• Dataset consists solely of anatomical scan data without associated metadata columns
• Specimen is preserved and scanned in three separate parts, requiring alignment for full reconstruction
• Scans are from a single specimen (GSE 4722), limiting population-level analysis
