Diagram outlining the workflow of the phylogenetic analyses carried out in this work. The character-by-taxon matrix has 67 taxa and 380 characters. The number of trees obtained from each iteration is shown next to the name with their length. A stand for the character-by-taxon matrix and the elements inside the curly brackets represent the OTUs removed before the analysis was run. The constrain refers to forcing GPIT-PV-30787 inside a clade with Plateosaurus. The Templeton Test in the two iterations only compared the total evidence trees (iteration 1.1 against iteration 1.5 and iteration 2.1 against iteration 2.5). The original character-by-taxon matrix by Rauhut et al. (2020) includes P. trossingensis as P. ‘engelhardti’, including several specimens (see text), and only two characters scored as polymorphisms: Ch. 17 (scored as 0 and 1), and Ch. 138 (scored as 0 and 1). In the second analysis, P. trossingensis is restricted to specimen SMNS 13200, where Ch. 17 is scored as 0, and Ch. 138 is scored as 1.
