I feel sorry for the dino, who was just doing what a hungry Tyrannosaurus (or “Garth” as they are known in Pal-Ul-Don) does. He's grabbing a bite to eat wherever he can: a steer, a hippo... He scares some humans (including some who die in a vehicle wreck). But jeez, he couldn't read the signs, could he? “You are now leaving Pal-Ul-Don and entering Tarzan country.” The dinosaur is not the only one in unfamiliar territory. When Raoul reports it to his superior officer he is almost arrested for being mentally ill!
“Nightmare in the Jungle” was written by Gaylord Dubois and drawn by Jesse Marsh. Marsh had done another dinosaur assignment in '60, when he did the movie adaptation of Dinosaurus! for Dell. You can find that full-length comic in Pappy's #1160.
The incredible cover was painted by artist Morris “Mo” Gollub.
