        Introduction. Phytosaurs are a group of fossil archosauriform reptiles commonly found in Upper Triassic (c. – Ma) sediments in North America and Europe, and less commonly in other regions such as India, Africa, East Asia, Madagascar and South America (Stocker & Butler, ).Phytosaurs have usually been regarded as the earliest diverging group within the crocodylian Cited by:   The Blasensandstein phytosaurs are among the stratigraphically lowest phytosaurs in the Germanic Triassic; ‘Zanclodon’ arenaceousFraas, (holotype and only known specimen: SMNS ) from the Schilfsandstein (Stuttgart Formation) of Baden-Württemberg is older (Carnian: Julian), but its identification as a phytosaur has been considered Cited by: Abstract: Leptosuchus Case, (Reptilia: Phytosauria) from the Late Triassic of the American West is represented by many specimens.
