Bend National Park can be referred to Borealosuchus. The name Borealosuchus is defined with reference to the monophyletic group including the last common ancestor of four crocodylians formerly classified as "Leidyosuchus" (B. sternbergii, B. acu-tidentatus, B. wilsoni, B. formidabilis) and all of its descendents (Brochu, 1997b).
