FIGURE 7 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 7 Growth pattern of the sectioned aetosaur Stagonolepis olenkae humeri (A: UOPB 00135, B: UOPB 00120, C: UOBS 02496, D: UOBS 02363, E: UOBS 01906, F: UOPB 00136, G: UOPB 00142, H: UOPB 00121, I: UOBS 02828, and J: UOPB 00137). Half of the picture is taken under normal transmitted light and the other picture half is taken under polarized light. Please note, that the normally transmitted picture does not show informative histological features. The coloured bars show preserved and counted cycles (zone and annulus). Specimen A-B and H preserve four growth cycles, specimen C, E, G, and I preserve three growth cycles, specimen D and J preserve two growth cycles and specimen F preserved six growth cycles. The arrows in specimens A-C, E, and H-J indicate sub-cycles. Humeri are arranged accordingly to their bone length. Scale bar represents 1 cm for each specimen.
