Fig. 2 | Details of the histology of Spicomellus afer, NHMUK PV R37142. a,c, Thin-section photographs of the fused rib and osteoderm. The darker region at the top of the image in a and to the top left of the image in c bears the histological characteristics of an osteoderm, while the lighter region below bears histological characteristics of the rib. A strip of structural fibres extending across this interface can be observed in c. b, Thin-section photograph of the spine of NHMUK PV R37142 S. afer showing a cortex of woven bone and an inner core of highly vascularized trabecular bone. d, A section of NHMUK PV R37142 S. afer with the osteoderm and rib sections segmented separately so the morphology of each can be seen. The osteoderm is in blue, while the rib is shown in white.Published as part of Maidment, Susannah C.
