a, PPC-SRµCT cross-sectional images through the developmental planes of all analysed teeth (for abbreviations, see text). Coloured lines indicate the six major stress markers (hypoplasias) used for cross-matching the teeth. b, Composite chart showing dental development. Tooth abbreviations as in a; individual cusps: mb, mesiobuccal; ml, mesiolingual; db, distobuccal; dl, distolingual. Grey bars, crown formation periods from initiation to termination; orange bars, root formation periods (light bands mark maximum root extension rate as a proxy for dental eruption). The vertical coloured lines correspond to the stress events shown in a. Scale bar, 1 cm.
