| 研究開始時の研究の概要 |
The project focuses on applying dental microwear texture analysis (DMTA), a method based on wear traces on teeth, to dinosaurs. Usually DMTA is applied to mammals. Recently the fellow successfully transferred it to extant reptiles, making it a promising tool to resolve niche partitioning in sympatric dinosaurs. Secondly, the project will improve comparability of DMTA between labs by investigating inter-microscope differences using a comparative dataset captured on a μsurf custom microscope by the fellow, with corresponding specimens, and re-scan these on the host's measuring system.

| 研究実績の概要 |
Publication of four related research papers. The alligator feeding experiment and a feeding experiment with combined mechanical properties testing of foodstuffs were both published in Frontiers in Ecology and Evolution. The budget was used for open access fees. Additionally, two papers on microwear in dinosaurs were published. The host and JSPS fellow were herewith the first to apply dental microwear texture analysis for diet reconstruction to dinosaurs. Leftover budget of the KAKENHI was used to purchase assorted chemicals for an ongoing project on sika deer dental anomalies. Genetic analyses will be conducted to elucidate whether observed agenesis of third molars is inherited through the X-chromosome.
