Uenlagia (“half-bird”)<br />
Several features of Unenlagia<br />
(originally described from<br />
Upper <strong>Cretaceous</strong> of<br />
Argentina) are more birdlike<br />
than in any other non-avian<br />
theropod so far discovered.<br />
<strong>The</strong> evidence suggests that it<br />
could flap its arm, although<br />
Unenlagia was much too heavy<br />
to fly with such a short wing.
