Mei long (translates as "Snoozing Dragons") was a Chinese species of Troodontosaurid that was as big as a man, and scaly, although the type specimen was a juvenile, fluffy and curled up, like it was sleeping (hence the name) . It was probably killed by volcanic ash, since active volcanos were common in the Cretaceous in Texas,
Tunisia, China (the place of Mei Long) and India.
- The Mei's size is depicted to be much larger, but they were actually the size of a duck.
- Their versions resembles the Troodons from Episode 6.
