So it foramen opens up posteriorly given that confirmed of the a highly-defined, posteriorly widening route
A small foramen can be obtained only ventral into rear stop of the dorsolateral ridge, to your posterolateral epidermis of surangular. The brand new foramen entry anteromedially through the surangular to go out of into the deep fossa to your anterior region of the medially projecting process. The fresh new medial term of foramen are larger than the fresh new horizontal phrase as in E. okeeffeae, S. inexpectatus, aetosaurs (age.grams., L. meadei and you may D. spurensis), Euparkeria capensis, H. ischigualastensis, P. kirkpatricki, and you may Crocodylomorpha (Gower & Weber, 1998 ; Nesbitt, 2007 , 2011 ; Short, 2002 ; Weinbaum, 2011 ).
Another foramen is anterodorsal into the that just explained for the the posterolateral body of your surangular, including underneath the dorsolateral ridge, but anterior into glenoid. With the medial facial skin of your own surangular, the possible exit for this foramen occurs in another anteriorly up against concavity just anterior on the large foramen to the anterior side of your medial projection; these two medial foramina is actually split up of the a little crest. The fresh new medial skin of one's surangular was concave anterior to the foramina.
