5.2.13 Squamosal

New morphology and laterally facing positioning of your squamosal is extremely similar to that of aetosaurs instance S. robertsoni, A good. ferratus, P. andressorum, and you will D. spurensis (Profile 4u, v; Walker, 1961 : fig. 2; Brief, 2002 : fig. 2; Schoch, 2007 : fig. 8; Schoch & Desojo, 2016 : fig. 4). Brand new surprisingly-shaped squamosal (referred to as “sword-like” having Good. ferratus because of the Schoch, 2007 ) versions the posterodorsal margin of your own supratemporal fenestra. T. ruthae is served by a great laterally dependent squamosal; but not, Roentgen. callenderi and you may aetosaurs do not have the obvious ventral projection included in you to taxon (Ezcurra ainsi que al., 2017 ).
