No fenestra could be located on the largely undisturbed right or thesomewhat flattened left side of BPI 5207, and there is no evidence for the presence of anelongated fenestra in other (albeit mostly disarticulated) specimens. Openings in this region ofthe skulls of archosaurs come in a diversity of forms. Among those taxa discussed by Juul(1994), for example, the openings in Shansisuchus and Chalishevia are large circular fenestraelying between premaxilla, maxilla, and nasal, with a neighbouring fossa in the latter element(Gower & Sennikov 2000). This is quite different to the similarly positioned openings in thedinosaurian and rauisuchian taxa that Juul mentioned. In addition to requiring more preciseinforma
