Mr. DNA's Fun Trivia
- The name Mussaurus means "mouse lizard," which was based on the tiny size of the first fossils discovered which turned out to be juveniles, not adults.
- The achievement "Little Little Mussaurus" plays on the dinosaur's misleading name and the contrast between its tiny juveniles and medium-sized adults.
