Fig. 6 in Distinguishing Quaternary glyptodontine cingulates in South America: How informative are juvenile specimens?
Fig. 6. Osteoderm histology of juvenile glyptodont Glyptotherium sp. (UNIRIO-PM 6231) from the Late Pleistocene of Aurora do Tocantins, Brazil. A. Osteoderm from lateral regions of the dorsal carapace (II), showing highly vascularized superficial cortex composed of woven fibered bone; several vascular canals are opened to the surface. Natural light photograph (A1), under polarized light (A2). Note the monorefrigent nature of the cortical tissue. B. Close up of the woven fibered bone matrix; bone cell lacunae are abundant and they are haphazardly arranged. C. Detail of the cortical bone at the marginal region of the osteoderm; the vascular spaces are larger than in the superficial cortex of the same specimen. Patches of slightly birefringent tissue are present, indicating preferential fiber orientation in some areas (C2). Natural light photograph (C1), under polarized light (C2). D. Osteoderm from lateral regions of the dorsal carapace (III); showing woven fibered bone in the marginal region of the osteoderm viewed under polarized light with lambda compensator. E. Resorpion cavities in the inner core. The bone trabeculae are composed of woven fibered bone. F. Cortical bone at deep cortex. Natural light photograph (F1), under polarized light with lambda compensator (F2). Abbreviations: its, inter-trabecular spaces; nvc, neurovascular canals.
