Worn right upper molar (M2; here mirrored) of Ma. patachonica (PIMUZ A/V 4118) in occlusal (G), lingual (H), and mesial (I) views. J–L. Unworn right deciduous premolar (dP4; here mirrored) of Ma. patachonica (MHNG GEPI V3659) in occlusal (J), buccal (K), and lingual (L) views. M Left maxilla fragment with P4, M1–2 of Ma. patachonica (MHNG GEPI V3659). The illustration of C. normalis' M1 in A of was based on the specimens MLP 83-III-2–1 and MLP 85-V-VII-3-38a. The illustration of T. lydekkeri' s M1 in B was based on the specimens MACN-A 9269–88 and YPM VPPU 015717.The illustration of Ma. patachonica's M1 in C was based on the specimen MACN-PV 11361, among other specimens. In A–C, the labels of controversial structures are in bold and relevant cusps are highlighted in different colours: blue for paraconule, red for protocone, green for metaconule, yellow for hypocone, and dark yellow for hypocone–metaconule. Notice that even though the dP4 (J–L) and the maxilla fragment with P4, M1–2 (M) share the same specimen number (MHNG GEPI V3659), these are from different individuals considering their different and incompatible ontogenetic stage (see the extreme wear in the permanent P4 in M). dif distolingual fossette, ecg ectocingulum, ets entostyle, hy hypocone, hy-mtl hypocone–metaconule, lmef lingual median fossete, maf mesiolabial fossette, me metacone, mef median fossette, mif mesiolingual fossette, ms mesostyle, mt metastyle, mtl metaconule, pa paracone, pcg precingulum, pplc preparaconule crista, pprc preprotocrista, pr protocone, prl paraconule, ps parastyle, pscg postcingulum, psmlc postmetaconule crista, psplc postparaconule crista, psprc postprotocrista, tb trigon basin

K Manus (carpals, metacarpals and phalanges) in anterior view. In E the olecranon fossa was restored, so it in PIMUZ is not as deep as it should be. In K the carpals and metacarpals were glued together with the different elements in the right position, but in many cases with a wrong orientation (e.g., pisiform and Mc IV).

The central bar of each box represents the median of the population, while upper and lower bounds are 75th and 25th percentiles, respectively. Boxes show 50 % of the population and whiskers extend showing the minimum and maximum values in a range of 1.5 times the length of the box. Circles mark the atypical values of CS located beyond to 1.5 times the box length distances.
