MicroCT scan of the skull of a dugong (Dugong dugon). This dataset was part of a study on the evolution of the inner ear.
Usage Notes
The skull was scanned in two parts. "skull 1" covers the area of the inner ear that was studied in the related publication by Grunstra et al. (2024).
X-ray tube: FXE Direct Beam
Detector: Perkin Elmer Y.Panel 4343 CT
Exposure time: 1 s for 1980 projections per scan
Voltage: 160 kV
Current: 75 µA
Filter: 1 mm Copper
Reconstructed voxel size: 98.8 µm
The image stack was cropped and converted into a TIF image stack using the software Dragonfly.
This specimen was used in a study on the inner ear (see "Publications") the segmented inner ear data is available here: https://osf.io/9mtwh/
