Compsognathus was a chicken-sized and built much like Archaeopteryx, the "bird-dinosaur." It had a long neck and very long tail, three-toed feet on legs that were twice as long as it's arms. There were maybe only two clawed fingers on each hand, as in the huge Tyrannosaurus.

Length: 2 feet.
Weight: 6 pounds 8 ounces
Time: Late Jurassic
Place: Europe (southern Germany and southeast France)
