Cross-section of correlation of vertical profile composites of the Bauru Group.

<p>Showing the sequence stratigraphic framework at facies association level of the Bauru Group.</p

Geological map of the Bauru Group, Paraná Basin (modified from [104]).

<p>The outcrops that yielded Itasuchidae specimens is located with the crocodile outlines. A-B and C-D are regional geological sections.</p

Calibrated strict consensus tree from 225 MLTs (1520 steps, CI = 0.304 and RI = 0.692).

<p>The phylogenetic relationships (thin lines) come from the strict consensus tree calibrated with the geological ages (chronostratigraphic chart). Thick lines represents the species temporal range based on specimens occurrence. Also, colors in thick lines represent the inferred habit for studied species.</p
