Makes me wonder, are there ancient beasts in Pern? The Fire-Lizards do look like dinosaurs flying. Or for people originating from Earth, that is. Are there ancient beasts who once roamed the world of the dragons?
The Dragons and Watch-whers are bio-engineered. Felines, runner beasts, herd beasts and canines were brought by the colonist. Were there creatures that failed to evolve and died out? Are there evidences left? Or did Thread eat all of the evidences?
It just makes me wonder...
