Sinornithoides youngi (Russell & Dong, 1994)

Name Means: "Chinese bird form" Length: 3.6 ft (1.1 m)
Pronounced: sy-NOR-nith-OY-deez Weight: 12 pounds (5.5 kg)
When it lived: Middle Cretaceous period - 110 MYA    
Where found: Mongolia, China    
    Troodontid specimens were recovered from three localities in China by the Sino-Canadian expeditions between 1987 and 1990. These included Sinornithoides youngi, which is the most complete troodontid skeleton ever found. Sinornithoides revealed for the first time the arm, back, and neck structure of the troodontids. S. youngi revealed for the first time the arm, back, and neck structure of the troodontids. The degree of ossification and the relative proportions of the body suggest it was almost mature.  Based on a mostly complete skeleton and skull,  This turkey-sized dinosaur had very long legs and was a fast runner. It was a very intelligent dinosaur, as it had a relatively big brain. It was the first dinosaur discovered with  primitive feathers.
