This undated handout artist rendering provided by the National Science Foundation shows the newly discovered Triassic, carnivorous dinosaur, Tawa hallae. Newly described dinosaur fossils from New Mexico are helping scientists better understand the early development of these ancient creatures. The six-to-12 foot long, meat-eating creature, Tawa hallae, is described in Friday's edition of the journal Science.
