Ornithomimidae (meaning "bird-mimics") is an extinct family of theropod dinosaurs which bore a superficial resemblance to modern ostriches. Ornithomimids were fast, omnivorous or herbivorous dinosaurs known mainly from the Late Cretaceous Period of Laurasia (now Asia and North America), though they have also been reported from the Lower Cretaceous Wonthaggi Formation of Australia.[4]
