TABLE 4. — Proportions of the dentary in Tiupampa metatherians and some didelphids.Abbreviations: Hm3, labial height of the dentary below m3 between trigonid and talonid; L, length of the dentary from the posterior edge of the condyle to the anterior end of the symphysis. Measurements for Pucadelphys and Mayulestes have been taken from Muizon et al. (2018: 415,table 5).Length of the dentary for Allqokirus is an estimation (e) of the adult length as evaluated by Muizon et al. (2018: 414) for the sub adult specimen MHNC 8267. Measurement are in mm. | | | Hm3/ | |
