An image often mistaken to be the rancor from battling a krayt dragon was in reality, a joke from the crew of ILM. They placed a model of one of the dragons from the film Dragonslayer in the arms of the rancor model and took a photo. The photo was included in the book Star Wars: Chronicles.
Creatures based on this dragon were included in Richard Chasemore's artwork of Jabba's Palace for Inside the Worlds of Star Wars Trilogy, based on what Chasemore called a "cut scene."
