Supplementary Data Dental form and function in the early feeding diversification of dinosaurs Antonio Ballell, Michael J. Benton and Emily J. Rayfield Science Advances The Supplementary Data of this article contains two folders named 'Thecodontosaurus BRSUG 28221' and 'Dinosaur teeth 3D models'. Thecodontosaurus BRSUG 28221: Computed Tomography (CT) data of the specimen BRSUG 28221, a Thecodontosaurus antiquus fragmentary maxilla containing a tooth. The CT dataset contains 1831 TIFF images with voxel size (x, y, z) of 0.011412 mm. Dinosaur teeth 3D models: 3D models of individual teeth of 11 early dinosaurs included in the analyses. The 3D models are surface files in PLY format: buriolestes_schultzi.ply eodromaeus_murphi.ply eoraptor_lunensis.ply herrerasaurus_ischigualastensis.ply lesothosaurus_diagnosticus.ply manidens_condorensis.ply massospondylus_carinatus.ply ngwevu_intloko.ply plateosaurus_engelhardti.ply saturnalia_tupiniquim.ply thecodontosaurus_antiquus.ply
