Description of the research topic:
"During the 300 million years evolution of sauropsid reptiles, one of the most spectacular phenomenon is the diversification of their tooth morphology and food processing. This is especially true in herbivorous forms, where still it is not clear whether the innovations and changes in the flora (e.g. the appearance and diversification of flowering plants in the early Cretaceous) could be causes of the development of new types of chewing mechanisms, dentitions, tooth morphologies and tooth structures or not.The aim of the project is to fulfill biomechanical and morphometric analyses on the most relevant Mesozoic sauropsid reptile fossils completed with tooth wear analyzes. This can help for a better understanding of the plant-herbivore interaction either on a well defined paleo-landmass or in a critical period of the Mesozoic. The project is completed with the study of the dentition and consumed food of extant forms as well giving an important support for the feeding mode and food preference of extinct sauropsids.
