Chalishevia is an extinct genus of erythrosuchid archosauriform from the Ladinian Bukobay Formation of Russia (Orenburg Oblast).^[1] Though it is only known from a few fragmentary skull bones, the skull is estimated to be around 80 centimeters long, making it one of the largest erythrosuchids known.^[2]
