Figure 4 in The first record of fossilized soft parts in ossified tendons and implications for the understanding of tendon mineralization

Figure 4. SEM images and EDS spectra of fossil and recent tendon samples. A–I, fibrous matrix in the vascular canals of: A, B, Edmontosaurus regalis (UAMES 52615); C–F, Homalocephale calathocercos (MPC-D 100/1201); G, Pinacosaurus grangeri (ZPAL MgD-II/32); H, I, mineralized tendon of modern turkey (Meleagris gallopavo, GIUS-12-3741), note the presence the of fibres both in the vascular canals (white asterisks) and in the bone matrix (black asterisks). J–L, EDS spectra of: J, Edmontosaurus regalis (UAMES 52615); K, Homalocephale calathocercos; L, Meleagris gallopavo showing calcium, phosphorus and oxygen as dominant components in tendon mineral matrix in fossil and recent tendon samples. Note that carbon signal is omitted in the spectra (see Material and methods).
