Figure 6A–D in Theropod Fossils from the Upper Triassic Dockum Group of Texas, USA, and a Brief Overview of the Dockum Theropod Diversity

Figure 6A–D. Two interpretations for the postacetabular process of Dockum herrerasaurid (TTU-P10082). A, B. The reconstruction in previous works of Nesbitt and Chatterjee (2008) and Martz et al. (2013), in lateral and medial views. C, D. The reconstruction in this study in lateral and medial views. Note that the dashed lines in yellow demonstrate the discontinuous ventral margin and the non-horizontal alignment of the sacral vertebrae; whereas the black dashed lines suggest a more plausible morphology, as discussed in the text.
