Supplementary information for Dental microwear texture analysis revealed the temporal dietary shift within Cretaceous ornithopod dinosaurs.

Dental microwear texture files of ornithopod dinosaurs used in the study. Files are in "sur" format that record three dimensional surface morphology. Surface roughness parameters taken from these dental microwear texture files and results of statistical analyses conducted on these parameters. The phylogenetic tree used for evolutionary model fitting and results of the model fitting analyses.
