2021-08-17 High-resolution computed tomography (HRCT) dataset of Mengshanosaurus minimus holotype (IVPG-T002) doi:10.11922/sciencedb.j00001.00289 en Mengshanosaurus minimus is a group of choristoderes that has been reported from the Lower Cretaceous Mengyin Formation of Shandong Province. The holotype is an almost complete fossil skull with a total length of 35 mm, representing a juvenile. The high-resolution computed tomography (HRCT) dataset of Mengshanosaurus minimus holotype (IVPG-T002) consists of 4 subsets in total: (1) “slice images.zip”, 10.5 GB, consists of a scan parameter document (parameter.pcr) and 5354 original CT slice images (*.tif); (2) “specimen photo and CT model images.zip”, 362 MB, includes a photo of the holotype specimen (holotype photo.tif) and an image showing the CT model in various views (Mengshanosaurus minumus CT model.tif)；(3) “videos.zip”, 2.30 GB, includes three video documents showing the three-dimensional CT model of the skull spinning around roll, pitch, and yaw axes (*.avi)；(4) “skull polygon mesh.stl”, 881 MB, is a three-dimensional surface model of the holotype skull.The Mengshanosaurus minimus holotype was scanned by using the HRCT scanner phoenix v|tome|x m, and the original CT data has a spatial resolution of 7.5197 μm. The three-dimensional reconstruction of the CT model of the skull, the images and videos of the CT model of the skull, and the three-dimensional surface model of the skull were finished on the VG Studio Max 3.4.0.
