Zuolong is potentially one of the most primitive coelurosaurians known

It lived in the Jurassic period and inhabited Asia. Its fossils have been found in places such as Xinjiang (China), about 161 to 155 million years ago.

The genus name is in honour of General Zuo Zongtang‭ (‬also known as General Tso‭)‬,‭ ‬who in the nineteenth century secured Xinjiang for China.‭ ‬The species name is in honour of Hilmar Sallee who bequeathed money for the expedition in their will.

It was about 3.1 meters long, and is known from a skull and partial skeleton.

Zuolong was a carnivore. ‬Due to its small size it was probably a predator of small vertebrates such as lizard,‭ ‬primitive mammals to even smaller dinosaurs.

Zuolong however may have been potential prey for even larger theropods that are also known from the Shishugou Formation such as Monolophosaurus and Sinraptor.
