The character scorings of Antusuchus rionegrinus were introduced into a morphological dataset comprising 444 characters and 117 taxa published by Fernández Dumont et al. (2024) and Novas et al. (2025), which represents an updated version of the dataset of Bravo et al. (2021) and previously published data matrices (Clark, 1994; Ortega et al., 2000; Pol & Apesteguía, 2005; Pol, 2003; Turner & Sertich, 2010; de Andrade et al., 2011; Leardi et al., 2015a; Leardi et al., 2015b; Fiorelli et al., 2016; Pol et al., 2012; 2014; Martinelli et al., 2018; Martinez et al., 2019).

We added the new taxon and other peirosaurians that were not previously included (Pepesuchus, Itasuchus, Kostensuchus atrox), as well as several modifications to the character scorings of certain taxa
