During my PhD in Evo-devo, I describe and compare shark teeth to understand which genetic and physical factors, might control a specific tooth form acquisition. I mostly focus on scyliorhinid teeth (catsharks), which I microCT scan and include in 3D geometric morphometric analyses. I combine this descriptive approach with functional tests on teeth of Scyliorhinus canicula embryos to decipher the role of specific proteins in shaping a shark tooth.
Using histological sections, I also describe the diversity of calcified cartilage patterns in chondrichthyans (sharks, skates, rays, and chimaeras) to provide insights into the evolutionary history of endoskeletal mineralisation in jawed vertebrates.
