FIGURE 5 in Growth and limb bone histology of aetosaurs and phytosaurs from the Late Triassic Krasiejów locality (sw Poland) reveals strong environmental inFluence on growth pattern

FIGURE 5 Histological growth of the aetosaur Stagonolepis olenkae on the example of the humerus UOPB 00120 (A-H). Pictures A, C, E and H were taken under normal transmitted light and pictures B, D, and F-G were taken under polarized light. Scale bars represent 1 cm for specimen A, 100 micrometres for specimens B-C, and 500 micrometres for specimens D-H. Abbreviations: eb = endosteal bone, ec = erosion cavity, hpfb = higher organized parallel-fibered bone, lpfb = lower organized parallelfibered bone, mc = medullary cavity, mr = medullary region, pos = primary osteon, sos = secondary osteon, subc = sub cycles, svc = simple vascular canal.
