Thin section micrographs of cross sections through modern goat bones, collected in the desert near the dinosaur bone locality A. Central cracks spreading from the Haversian canal outwards, caused by desiccation. B. Secondary osteon isolated by circumferential cracks. Perpendicular to the circumferential cracks small peripheral cracks are visible. Both crack types are due to bone desiccation. Both scale bars are 100 μm.
