Extended Data Fig. 5 | Thin section photomicrograph (plane-polarized light) showing detail of the structural fibres in the upper osteodermal part of the rod. Structural fibre bundles intersect roughly perpendicular to each other. The opaque cast in the top half of the image is probably diagenetic alteration.
