The morphology and sideways up against orientation of your own squamosal is extremely like aetosaurs instance S. robertsoni, An effective. ferratus, P. andressorum, and you will D. spurensis (Shape 4u, v; Walker, 1961 : fig. 2; Quick, 2002 : fig. 2; Schoch, 2007 : fig. 8; Schoch & Desojo, 2016 : fig. 4).

T. ruthae comes with good sideways established squamosal; although not, Roentgen. callenderi and you may aetosaurs do not have the obvious ventral projection used in one taxon (Ezcurra ainsi que al., 2017 ).
