Figure 6 in The first record of fossilized soft parts in ossified tendons and implications for the understanding of tendon mineralization

Figure 6. Fossilized soft parts released from the demineralized tendons of Homalocephale calathocercos (A, C–E) and Edmontosaurus regalis (B, F–P). The sample of H. calathocercos (A) and E. regalis (B) during demineralization. Note the presence of tubular structures released from the mineral phosphate matrix of the fossilized tendons. Dense network of blood vessels forming a mesh-like structure with thicker and thinner vessel-like tubes adjacent to the surface sheath of the partially demineralized tendon of H. calathocercos, visible in: C, transmitted light; D, SEM image (yellow asterisk indicate spot for EDS survey); E, EDS spectrum collected from the blood vessel-like structures reveals the presence of alumino-silicates (Al, Si, O) as the main components; F, tubular structure resembling blood vessels released during the demineralization process; G, the surface of the tubular structure released after demineralization, note the presence of
