|Allosaurus claw boasts exceptional preservation, size and presentation. Dinosaur claws are much more rare than dino teeth, as dinosaurs' teeth were replaced throughout their lifetimes, whereas claws were not. A formidable predator, Allosaurus had short arms with three-fingered hands completed by razor-sharp claws.|
Allosaurus hand claws are much larger than Tyrannosaurus.
|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. |
