Saleiro, André; Tschopp, Emanuel; Daasch, Alexander; Kaiser, Thomas M.; Wiesinger, Ria; Winkler, Daniela E.

This digital folder contains the dataset (1011 scans in total, plus an excel file with measured parameters that are frequently applied on dental wear surfaces for diet inference) of the publication “Acquisition of a dataset for dental microwear texture analysis (DMTA) of sauropod teeth: pre-analytical and post-processing steps for quality assessment” by André Saleiro, Emanuel Tschopp, Alexander Daasch, Thomas M. Kaiser, Ria Wiesinger, and Daniela E. Winkler.

The full paper is available as a preprint on PaleorXiv under the following DOI: https://doi.org/10.17605/OSF.IO/4XRWE

It is currently under peer-review for recommendation at PCI Paleo.

Data was collected between November 2021 and October 2023, at institutions in Portugal, Germany, and the USA.

This research was supported by the National Funds through the FCT—Fundação para a Ciência e a Tecnología, I.P., through the doctoral grant 2020.05854.BD attributed to AS. AS was further supported by FCT—Fundação para a Ciência e a Tecnología, I.P. through the Research Unit UIDB/04035/2020 (GeoBioTec; https://doi.org/10.54499/UIDB/04035/2020); the Project PTDC/CTA-PAL/2217/2021 (BioGeoSauria); and SYNTHESYS. Some tooth molds were taken by Emanuel Tschopp during his Alexander von Humboldt Fellowship for Experienced Researchers at University of Hamburg (UHH; Germany).
