Archaeornithoides deinosauriscus

†Archaeornithoides deinosauriscus was a small carnivorous theropod or early bird from the Late Cretaceous Djadokhta Formation of Mongolia. Known from fragmentary skull material including distinctive teeth, it is of uncertain phylogenetic placement, possibly an early avian or troodontid. Its hooked teeth suggest active predation on small prey in the arid sand-dune environment of Cretaceous Gobi.
