However, much of that research has focused on bird\u2010line archosaurs, resulting in a skewed view of Archosauria. Phytosauria, a hypothesized sister taxon to or early\u2010branching member of Archosauria, provides a potential outgroup condition. Most previous phytosaur endocranial studies were executed without the use of modern technology and focused on derived members of Phytosauria. We present a comparative <jats:styled-content style=\"fixed-case\">CT<\/jats:styled-content> examination of the internal cranial anatomy of <jats:italic>Wannia scurriensis<\/jats:italic>, the most basal known parasuchid phytosaur. <jats:italic>Wannia scurriensis<\/jats:italic> shows some overall similarity with extant crocodylians and derived phytosaurs in general endocranial shape, a large hypophyseal fossa, and trigeminal (<jats:styled-content style=\"fixed-case\">CN<\/jats:styled-content> V) innervation, but as a whole, the endocast has noticeable differences to crocodylians and other phytosaurs. The pineal region is expanded dorsally as in other phytosaurs but also laterally (previously unrecognized). <jats:styled-content style=\"fixed-case\">CN<\/jats:styled-content> V exits the pons in a more dorsal position than in <jats:italic>Parasuchus hislopi<\/jats:italic>,<jats:italic> Machaeroprosopus mccauleyi<\/jats:italic>, or <jats:italic>Smilosuchus gregorii<\/jats:italic>. <jats:italic>Wannia scurriensis<\/jats:italic> also exhibits a larger hypophyseal fossa relative to brain size than observed in <jats:italic>P.\u00a0hislopi<\/jats:italic> or <jats:italic>S.\u00a0gregorii<\/jats:italic>, which may indicate more rapid growth. The well\u2010preserved semicircular canals have lateral canals that are angled more anteroventrally than in derived phytosaurs. Extensive facial innervation from the large <jats:styled-content style=\"fixed-case\">CN<\/jats:styled-content> V indicates increased rostrum sensitivity and mechanoreceptive abilities as in <jats:italic>Alligator mississippiensis<\/jats:italic>. These endocranial similarities among phytosaurs and with <jats:italic>Alligator<\/jats:italic> indicate conserved ecological and functional results of an aquatic lifestyle, and highlight a need for
