*Mussaurus* is a genus of herbivorous sauropodomorph dinosaur that lived in southern Argentina during the **Early Jurassic**, specifically the Sinemurian stage.
Despite its name meaning "mouse lizard," adults were medium-sized dinosaurs, while juveniles were famously tiny.

---

## Appearance
- Small to medium-sized sauropodomorph with a long neck and sturdy limbs
- Juveniles are notably tiny compared to adults, reflecting the species' famous growth difference
- Adults have a more robust build with a deep chest and strong hind legs
- Skin patterns vary depending on cosmetic genes
- In-game size: **8 blocks long** and **3 blocks tall**

---

## Behavior
- **Neutral**: Will not attack unless provoked
- Flees from large predators or sudden threats
- Often found in small family groups or herds
- Juveniles may follow adults for protection
- Occasionally rears up to reach higher vegetation

## <img width={64} src="https://i.imgur.com/DTOgOBL.png" alt="Mr.DNA"/> 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.
