- Project title
- Analyse biomécanique des mâchoires de nautiles
- Description of the project
- A very few studies have tried to link rhyncholite shape, feeding function, and diet. Indeed,the function of rhyncholite remains poorly understood as most studies have been limited to a qualitative and biometric comparisons of rhyncholite types. Moreover, information on the functioning of the buccal apparatus in living nautilids and other cephalopods is largely lacking, making inferences on the function and ecology of fossil forms even more difficult. Functional and dietary inferences for fossil nautilids are only possible by means of quantitative, comparative approaches involving both fossil and extant taxa. Consequently, the question of how the form of the nautilid feeding apparatus relates to function, feeding behaviour, and the environmental context remains unanswered.The goal of this project is to thoroughly and quantitatively characterize the morphological and functional changes in the nautilid feeding system throughout their evolution. Specifically, we will test the influence of rhyncholite shape on feeding performance by coupling statistical analysis of shape (geometric morphometrics) with biomechanical simulations borrowed from engineering
