Mei long lived in China during the Early Cretaceous period, over 125 million years ago.
Mei long were the size of a small child - about 3.3 feet tall and 14 feet long. They also had razor sharp teeth and claws.
Like many predatory dinosaurs and all dromaeosaurs as well as troodonits, Mei long hunted in packs.
The sound effects of Mei long are that of raven, vulture, and turkey.
