Adult story, not entirely dissimilar to Jeff Smith's Bone, about a dinosaur who crosses a genie and finds himself in another world. Printed in 1973.
Nice plot summary from Comixjoint: The horny little green dinosaur returns for more adventures in issue #2, though his name has apparently been changed from Picadillo to Picallo. Once again, Johnny Chambers employs the talents of George Metzger and Robert Inwood to elevate the illustrative value of his comics.
Where else would a swashbuckling tale by George Metzger result in the tough-as-nails main character pleading for a break from his God (the cartoonist), end up transformed into a fuzzy bear and get plopped into an entirely different little green dinosaur story? Only here my friends!
