Figure 7 in A new dentition-based phylogeny of Litopterna (Mammalia: Placentalia) and 'archaic' South American ungulates

Figure 7. Right lower molars of relevant SANUs in occlusal view. A, p1–m3 of the indaleciid Indalecia grandensis [PVL 4186 (p1–p2 mirrored)]. B, p2–m3 of the notonychopid Notonychops powelli [PVL 4298 (mirrored)]. C, p1–m3 of the notoungulate Simpsonotus praecursor [MLP 73-VII-3-11 (holotype; mirrored)]. D, p1–m3 of the astrapothere Trigonostylops wortmani [MNHN.F.CAS188 (mirrored)]. E, p2– m3 of the xenungulate Etayoa bacatensis [cast of GM 32 (holotype; mirrored)]. F, p1–m3 of Eoastrapostylops riolorense [PVL 4216, p1–m2 (holotype; p1–p5, m2 mirrored); PVL 4216, m3. G, p4–m3 of Propyrotherium saxeum [LIEB-PV 3200 (mirrored)]. Relevant anatomical features of the dentition are labelled. More information on the specimens and observations are in Supporting information, File S2. The asterisk is labelling either a paracristid in H1 or a very reduced paraconid in H2 in Simpsonotus praecursor, the tested hypotheses in our analyses. The question mark (?) next to the paraconid of Simpsonotus praecursor is to reflect that in the H1 matrix, this cusp was scored as a paraconid, whereas in the H2 matrix it was scored as a twinned metaconid. For information about the tooth position convention, check the Material and methods. Abbreviations: end, entoconid; hlph, hypolophid; hyd, hypoconid; hyld, hypoconulid; med, metaconid; pad, paraconid; prd, protoconid; pscd, postcristid (or postentocristid). Scale bars equal 1 cm.
