Ornithosuchidae differ from other carnivore archosaurs in the unique morphology of the jaw apparatus and postcranial skeleton. Various, often diametrically opposed, points of view have been expressed regarding their trophic adaptations – from carnivory and scavering to piscivory. The most reasonable hypothesis seems to be that ornithosuchids were hyperanisodont carnivorous macrophages in the middle size class. Moreover, there are some analogies between ornithosuchids and saber-toothed therapsids and mammals.

Ornithosuchidae отличаются от других хищных архозавров своеобразным строением челюстного аппарата и посткраниального скелета. Относительно их трофических адаптаций высказывались различные, зачастую диаметрально противоположные точки зрения – от плотоядности и падалеядности до рыбоядности. Наиболее обоснованной представляется гипотеза о том, что орнитозухиды были гиперанизодонтными плотоядными макрофагами в среднем размерном классе. При этом имеются некоторые аналогии между орнитозухидами и саблезубыми терапсидами и млекопитающими.
