Any "lizard-hipped" dinosaur species (order Saurischia), with hip bones arranged like those of modern reptiles , the pubis bone pointed forward and down.
The order includes all carnivorous and some giant herbivorous dinosaurs. Saurischians evolved from small bipedal dinosaurs called thecodonts; they first appeared in the Late Triassic epoch (227206 million years ago). The order consists of three suborders: theropods , sauropods , and staurikosaurs (suborder Staurikosauria). Staurikosaurs, known only from the incomplete remains of a few species, seem to have been medium-sized flesh-eaters similar to the theropods. See also ornithischian .
