FIG. 34 in Dental ontogeny in the early Paleocene placental mammal Alcidedorbignya inopinata (Pantodonta) from Tiupampa (Bolivia)

FIG. 34. — Wear facets on the first molars of Alcidedorbignya inopinata: A, partial left maxillary (MHNC 13960) of juvenile (stage 4) with M1 featuring a small wear facet on the on the mesial edge of the paraconule and on the preparaconular crista; B, the same with wear facet outlined with a red line; C, partial left mandible (MHNC 13964) of juvenile (stage 4) with m1 showing wear facet on the posterior edge of the protocristid; D, the same with wear facet outlined with a red line. The photographs of this figure have been obtained using an RTI (Reflectance Transforming Imaging) setting as indicated by Decombeix et al. (2021) with some specifications, as follows: we used a Canon EOS 5DS digital camera equipped with a Canon MP-E 65 mm macro lens (both Tokyo, Japan); and LEDs of the two lower rings of the light dome were used (i.e., 42 LEDs). Snapshots were extracted using the default' mode (for A and B, light source coordinates X = –0.34, Y = –0.34); for C and D, light source coordinates X = –0.31, Y = 0.44). Scale bar: 2 mm.
