SEB Annual Conference 2022

2022 will find over 1500 experimental biologists from across the globe converging on the third-largest French city near the Mediterranean coast and the fastest-growing city in the country over the past 25 years - Montpellier, France

Tessellated material systems, meaning self-similar subunits arranged to form surface structures, are found throughout various unrelated taxa as well as over a broad range of sizes. An especially interesting system constitutes the armadillo carapace, a rare example of mammal armor involving hard mineralized elements, so called osteoderms embedded in soft connecting tissue. Previous work focused on the structural integrity and histology of individual osteoderms. However, the larger scale organization of armadillo tilings has never been subjected to a larger scale comparative analysis, although the mechanics (e.g. overall fracture resistance) of a tessellation is linked to the geometrical arrangement of its subunits. In this study we digitally examined osteoderm carapaces from micro-CT scans of twelve armadillo species, representing all major lineages within the armadillo phylogeny, in order to quantitatively compare and describe osteoderm shape as well as arrangement and distribution within the entire carapace. Results show that five- and six-sided osteoderms are tied to positive Gaussian curvature similar to the patches on a soccer ball, where a comparable combination of pentagons and hexagons is used. Furthermore, osteoderm number per surface area of entire carapaces reflects a deep split in armadillo phylogeny, separating the two major groups Dasypodidae and Chlamyphoridae. Additionally, Chlamyphorinae display an outstanding carapace architecture that consists of bands comprising exclusively rectangular osteoderms, potentially related to functional adaptations to a specialized nocturnal and fossorial lifestyle that requires increased mobility compared to other armadillo species, while possibly also leading to a decrease in protective performance of the carapace. Our study reveals a hitherto understudied diversity of carapace structure and function in armadillos, a deeper understanding of which will yield further insight into the evolutionary history of the taxon.
