Brand new ventral articular epidermis holds a couple of convex surfaces split up because of the an excellent concave skin
5.2.13 Squamosal
The new morphology and laterally facing orientation of squamosal is quite similar to that of aetosaurs such as for instance S. robertsoni, A good. ferratus, P. andressorum, and you will D. spurensis (Contour 4u, v; Walker, 1961 : fig. 2; Quick, 2002 : fig. 2; Schoch, 2007 : fig. 8; Schoch & Desojo, 2016 : fig. 4). Brand new surprisingly-formed squamosal (known as “sword-like” having A good. ferratus of the Schoch, 2007 ) models the posterodorsal margin of the supratemporal fenestra. T. ruthae also offers an effective laterally centered squamosal; but not, R. callenderi and aetosaurs lack the pronounced ventral projection utilized in one taxon (Ezcurra et al., 2017 ).
The squamosal holds about three techniques, a keen prior process, a beneficial posterodorsal processes, and you may an effective posteroventral processes. The latest mediolaterally slim anterior techniques is the premier of your about three and you can articulates ventrally towards quadratojugal, models a little portion of the posterodorsal margin of the lateral temporary fenestra, and articulates dorsally to the posteroventral edge of new postorbital.
