3. Meet the Archaeopteryx
The Archaeopteryx is the earliest known bird considered to be a
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.
