Asa Steele's backyard had always been a very ordinary, standard sort of place - till his dog Bowser began to find dinosaur bones out there somewhere. And down in the orchard they found some strange metals, unseen on Earth before.
With the help of Bowser and the local simpleton, Hiram, Asa makes contact with an enigmatic, catfaced alien dwelling in his orchard. It is Catface who holds the key to the mystery - a break in the fabric of time itself where travel was possible back to the primeval beginnings of the Earth...
Note: published in the US under the title Mastadonia.
