 | A virtually complete Struthiomimus sedens hand, mounted in a lifelike pose. As in all members of the theropod subgroup Ornithomimidae, all three fingers are nearly the same length. Struthiomimus, meaning ostrich mimic, is known from the Late Cretaceous in North America. The genus possessed a small, light, toothless skull, a slender, flexible neck and, most likely, a birdlike horny beak covering the jaws. SEE. |  |
