B, C, photomicrographs of the deciduous molariform, taken with the scanning electron microscope, showing the vestigial enamel (VE) without crystalline structure. D, cross-section parallel to the occlusal plane of a permanent molariform. E, F, photomicrographs of the permanent molariform, taken with the scanning electron microscope, showing detail of the enamel layer. Abbreviations: D, dentine; E, enamel; EDJ, enamel–dentine junction; VE, vestigial enamel; white arrowheads show incremental lines. ; Published as part of Ciancio, Martín R, Vieytes, Emma C, Castro, Mariela C & Carlini, Alfredo A, 2021, Dental enamel structure in long-nosed armadillos (Xenarthra: Dasypus) and its evolutionary implications, pp. 1237-1252 in Zoological Journal of the Linnean Society 192 (4) on page 1243, DOI:10.1093/zoolinnean/zlaa119, http://zenodo.org/record/5301251
