FASA 365 Day 91, 1879 Game line, Rheinpercheroneros, 10-12 ft tall. Herbivore. Gruv “work horse”
Naturally armored, like a rhinoceros. Flat leathery tail appearing to be a single plate of the armor covering its body.
Big, strong, and docile enough to be trained, like Earth’s Percheron Horse breed.
Clearly from the Gruv, as noted by the look of a dinosaur.
