Single Crystal Analysis of Conodont Denticles by using Simultaneous SAXS/WAXS Studies

Conodonts, marine organisms from the Paleozoic to Triassic eras (495-199.6 Ma), are notable for their fossilized denticles central to their feeding. Beyond their stratigraphic use, these denticles shed light on early vertebrate evolution and exhibit intricate, naturally optimized structures. These are primarily inorganic-organic nanocomposites, with the main components being calcium carbonates, apatite, and silica. Our research focuses on the detailed analysis of these denticles to inform bio-inspired material design. Using simultaneous SAXS/WAXS, we identified fluorapatite as the primary crystalline constituent. This exploration promises to expand our understanding of ancient skeletal architectures and drive innovations in bio-inspired material applications.
