''Ebrachosuchus'' is an extinct genus of basal phytosaur known from the Late Triassic (late Carnian stage) of Bavaria, southern Germany. It is known only from the holotype BSPG 1931 X 501, a complete skull missing both mandibles. It was collected at Ebrach Quarry, bed number 9 from the late Carnian-aged Blasensandstein Member of the Hassberge Formation. It was first named by Oskar Kuhn in 1936 and the type species is ''Ebrachosuchus neukami''.〔Kuhn, O. (1936). Weitere Parasuchier und Labyrinthodonten aus dem Blasensandstein des mittleren Keuper von Ebrach. ''Palaeontographica, Abteilung A'', 83:61-98.〕 Hunt and Lucas (1991) mistakenly referred to ''Francosuchus angustifrons'' as ''Ebrachosuchus angustifrons'', and considered it and the other two ''Francosuchus'' species, ''F. broilii'' and ''F. latus'', to be synonyms of ''E. neukami''. Furthermore, they reassigned the species to ''Paleorhinus'', and synonymized ''Ebrachosuchus'' with the former.〔Hunt, A. P., and Lucas, S. G. (1991). (The ''Paleorhinus'' biochron and the correlation of the non-marine Upper Triassic of Pangaea ). ''Palaeontology'' 34(2):487-501.〕 Subsequent researches accepted this referral. More recently, a phylogenetic analysis found ''E. neukami'' to be more closely related to Phytosauridae than to ''Paleorhinus'' and thus the genus ''Ebrachosuchus'' was re-validated, while ''F. angustifrons'' was reassigned as ''P. angustifrons'' as it shares unique synapomorphies with the type species of ''Paleorhinus'' (''P. bransoni'') and was found to be its sister taxon. ''F. broilii'' and ''F. latus'' were also removed from ''E. neukami'', as they were found to be nomina dubia. ==References==
