FIGURE 5. Scanning electron microscope images of NMMNH P-33798, Revueltosaurus callenderi maxillary tooth enamel microstructure in transverse section. 1, overview of tooth indicating approximate place where measurements and micrographs shown in this figure were taken; 2-8, close-up views showing enamel thickness variation, with EDJ oriented relative to overview in (1) and OES away from the same overview. Scale bars = 20 µm except 1 (2 mm), 3 (50 µm). Numbers in image are linked to further enlargements.
