Focused Ion Beam tomography on fossilized osteocytes

Yara Haridy, Markus Osenberg, André Hilger, Ingo Manke, Donald Davesne & Florian Witzmann
Osteocytes play a central role in bone metabolism in extant vertebrates, but their evolutionary history is poorly understood. Therefore osteocyte lacunae microstructure of fossil bone was studied on the nanometer scale by means of focused ion beam tomography (FIB). A osteostracan and a “placoderm” were imaged, the earliest groups with cellular bone, and secondary osteons respectively. To visualize and characterize the early bone composition via the morphology and distribution of osteocyte lacunae, thereby imaging the...
