3. Meet the Archaeopteryx

possible link between reptiles and birds.
 Paleontologists are debating if this bird could fly or have merely
glided from tree to tree.
 It ate mammals, lizards, insects, and fish.
 Its size was 14 inches long.
 It lived in Germany 150 million years ago.
 It ran, leaped, glided, and flapped.
 In any event it actually seems, that it was not a strong flier.
