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.

发表4篇相关研究论文。短吻鳄喂养实验和一项结合食品机械性能测试的喂养实验都发表在《生态学与进化前沿》上。预算用于开放获取费用。此外，还发表了两篇关于恐龙微磨损的论文。主持人和JSPS研究员首次将牙齿微磨损纹理分析应用于恐龙的饮食重建。KAKENHI的剩余预算用于购买各种化学品，用于正在进行的西卡鹿牙齿异常项目。将进行遗传分析，以阐明观察到的第三磨牙发育不全是否是通过X染色体遗传的。
