Abstract

On taxonomic issues, ontogenetic series and tooth replacement. Comments on Diphyodont tooth replacement of Brasilodon-A late Triassic eucynodont that challenges the time of origin of mammals by Cabreira et al. Recently, Cabreira et al. (2022) published a contribution analysing the dental replacement of Brasilodon, a cynodont from the Brazilian Norian, concluding that it had a mammalian (diphyodont) type of replacement. In this note, we will only deal tangentially with their main conclusion and instead will concentrate on criticism posed by Cabreira et al. (2022) to the contributions of Abdala et al. (2013) and Norton et al. (2020).
