DESCRIPTION
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. For access please contact Dr. Dhananjay Mohabey (dinomohabey@yahoo.com) or Dr. Bandana Samant (bandanabhu@gmail.com).

Micro-computed tomographic scans were performed at the the CTEES facility at the University of Michigan, Ann Arbor, MI, USA, using a Nikon XT H 225 ST with a 0.1-mm-thick copper filter. The scanner is equipped with a tungsten target and was autoconditioned to maximum capacity at 225 kV. Scan settings were as follows: voltage = 136 kV; current =155 uA; exposure time = 1 s; projections = 3142; frames captured/projection = 2; flux normalization = enabled; ring artifacts = minimized. Uniform cubic voxels were 0.028 mm on a side.

FILE LIST
The data set includes a stack of 1842 tiff images, a .vgi file, and a .vol file derived from the CT imaging.
