- Abstract
Comments on Diphyodont tooth replacement of Brasilodon - A late Triassic eucynodont that challenges the time of origin of mammals by Cabreira et al Available from: https://doi.org/10.7717/peerj.2875 24 Jasinoski, S.C., Abdala, F. & Fernandez, V. (2015) Ontogeny of the early Triassic cynodont Thrinaxodon liorhinus (Therapsida): cranial morphology. Considering the last phrase in this segment of the critique, the final conclusion of Cabreira et al. ([10]) installed in the contribution title (Diphyodont tooth replacement of I Brasilodon i - a Late Triassic [Norian] eucynodont that challenges the time of origin of mammals), is inexact because they imply the presence of diphyodonty in the Early Triassic (Induan) I Thrinaxodon i , although we are completely unable to see how they will integrate the information of Abdala et al. ([34]) to prove their claim. In palaeontological-neontological studies of ontogeny, which also include dentition (and we have expertise in this; e.g. Abdala & Giannini, [3]; Abdala et al., [2]; Flores et al., [16]; Jasinoski et al., [24]; Jasinoski & Abdala, [22]; Flores et al., [15]), skull size is certainly a very important factor, as are also the changes in allometry perceived from juvenile to adults.
