FIGURE 7. Scanning electron microscope images of (UCMP 165211), Krzyzanowskisaurus hunti premaxillary tooth enamel microstructure in transverse section. 1, overview of tooth indicating approximate place where measurements and micrographs shown in this figure were taken; 2-7, 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). Numbers in image are linked to further enlargements.
