Great Snoring Stegosaurs! — Scott E. Sutton

The Adventures of Dinosaur Dog # 5 - "Great Snoring Stegosaurs", by Scott E. Sutton
This is the long awaited 5th story in this popular adventure series about a boy, Benjamin (Banjo) Montgomery, and his dog, Dino, who has a doggy door that has become a time tunnel back to the age of dinosaurs.
Benjamin has formed a science team with his best friend Lee, his cousin Samantha and Dino to explore all the different times and dinosaurs that the tunnel takes them to.
And with the help of some "friends" back in time they just might survive being trampled, clawed or eaten by real dinosaurs. You see, these "friends" are the ones causing the time tunnel to exist and these "friends" are actually... ALIEN LIBRARIANS.
In this story the science team goes back in time over 145 million years ago to study Stegosaurs when they are attacked by a group of new dinosaurs that they have never seen before in any dinosaur book. Benjamin calls them "Birdosaurs" while Benjamen's best friend, Lee, calls them "evil psycho turkeys with teeth that can kill you."
In the middle of the attack Dino the dog disappears ... Is he just lost or ... worse.
