DescriptionMaxillary tooth histology of Heterodontosaurus.jpg |
Maxillary tooth histology of heterodontosaurid dinosaur Heterodontosaurus tucki Crompton and Charig, 1962 (BP/1/9007), from Lower Jurassic upper Elliot Massospondylus Assemblage Zone of South Africa. A. Histological sections: A1, primary ridge: thick band of translucent dentine lines the labial edge of the tooth, no enamel is present; A2, whole tooth: transversely sectioned at the base of the wear facet; A3, mesial ridge: histologically distinct dentine thickens and enamel is absent; A4, labial edge: on the mesial distal edges the enamel is extremely thin, resulting from wear and likely a natural thinning of the enamel, histologically distinct dentine is present, but thin; A5, lateral edge: the enamel is thickest with no distinct dentine present. B. Scanning electron micrograph of labial edge of tooth showing crest formation from differential wear from the last stage of polishing. |
