Dude coulda caught it in his mouth.

So Harry Turtledove's Worldwar series explores an invasion of Earth by small ish reptilian aliens.

My head canon for the aliens and they're differences in culture from humans is that they basically came from pre-meteor Earth and evolved from real velociraptors (which as I understand, were actually only about 3 ft/1 m tall, and were considered the most intelligent/pack forming dinos of their time).

Its an interesting series (if something of a bizarre premise).
