| 8uhsp_v1 | Acquisition of a dataset for dental microwear texture analysis (DMTA) of sauropod teeth: pre-analytical and post-processing steps for quality assessment | Dental microwear texture analysis (DMTA) has been widely used in the study of dietary habits and trends of animals, based on the abrasion patterns preserved in dental enamel. Therefore, it is seen as an important tool when it comes to understanding the ecology, niche partitioning, and competition between co-occurring taxa, both extant and extinct. During the Late Jurassic, sauropod dinosaur faunas were quite diverse, with distinct groups inhabiting the same ecosystems. Being the largest mega-herbivores of their ecosystems, competition for resources could have been a determining factor that led to such diversity, making sauropods a good study-group for DMTA. Here we describe the complete process of creating a large DMTA dataset, from the required pre-analytical molding, casting, and three-dimensional data acquisition to the post-processing steps to quality check the acquired data. A total of 119 teeth attributed to the major sauropod groups from the Late Jurassic were measured for the most commonly analyzed DMTA parameters. We describe in detail the production of dental molds, casts, and the steps taken throughout the measuring process. We also describe the way in which we tested the quality of our data, as well as the taphonomical implications for future studies using the resulting dataset. The end result is the first large DMTA sauropod teeth dataset, consisting of 1011 measurements. | 2024-11-12T11:39:47.345758 | 2024-11-19T20:14:13.064777 | 2024-11-12T15:17:51.117918 | 2024-11-08T00:00:00 | paleorxiv | 1 | accepted | 1 | 1 | https://doi.org/10.31233/osf.io/8uhsp | CC-By Attribution 4.0 International | DMTA; dinosaurs; open data; paleoecology; taphonomy; tooth wear | ["DMTA", "dinosaurs", "open data", "paleoecology", "taphonomy", "tooth wear"] | André Saleiro; Emanuel Tschopp; Alexander Daash; Thomas M.
