Reconstructed CT slices for Cranium of Castoroides (University of Michigan Museum of Paleontology catalog number UMMP VP 3110) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data resulting from a merge of two separate scans are offered here as a series of unsigned 16-bit integer TIFF images. There may be slight differences in voxel grey values between the two parts. The upper left corner of the first image (*_0000.tif) is the XYZ origin.

The four specimens (GSI SR/YS/1, GSI SR/YS/2, GSI SR/YS/3, and GSI SR/YS/4) are identified as tail clubs that are attributed to the basal sauropod Kotasaurus yamanpalliensis. The specimens were collected by the Geological Survey of India Southern Region (GSI SR) and, in 2018, the specimens were studied as a collaboration between GSI SR and the University of Michigan Museum of Paleontology. The specimens are housed in the collections of the GSI SR (Hyderabad, India).

Specimen FSAC CP 330_Macroprosopon_Occipital region was scanned with a Nikon XT H 225ST uCT system housed in the Department of Earth and Environmental Sciences at the University of Michigan. Scans were collected with the following settings: energy settings, 215 kV, 115 uA; source to object distance, 353.463794708252 mm; source to detector distance, 1104.999 mm; scanned with 3141 projections; voxel size, x = 0.0639753837488959 mm y = 0.0639753837488959 mm z = 0.0639753837488959 mm; slice dimension (in pixels), x = 1222, y = 2000; number of slices, 2000 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of 4151.70947265625 and a scale factor of 4.802938109992684, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
Specimen RTMNU/DG/VERT/1/55P/2020 is a partial dentary of a small noasaurid dinosaur collected from Late Cretaceous sediments near the village of Pisdura, Maharashtra, India. The specimen was collected under the auspices of a Joint Collaborative Programme through a Memorandum of Understanding involving the Geological Survey of India (Government of India, Ministry of Mines) and the University of Michigan Museum of Palaeontology. The specimen is housed in the Department of Geology of Rashtrasant Tukadoji Maharaj Nagpur University, Nagpur (Maharashtra) India.
