FIGURE 4. Phylogenetic analyses, with the Bootstraps and Bremer supports in each node. A. Simplified strict consensus cladogram, result from the two most parsimonious trees of 2381 steps following Arribas et al. (2019); B. Strict consensus of the Goniopholididae clade. Ophiussasuchus paimogonectes gen. et sp. nov. is recovered as the sister taxa of the clade Hulkepholis + Anteophthalmosuchus.
