Shanag was another dromaeosaurid who recently was tentatively placed in the microraptor group. Since it showed a mixture of traits from dromaeosaurids, troodontids, and avialaens, it is still relatively uncertain where this dinosaur should fall. It was about 1.5 meters long and would have weighed about 5 kg. It was found in the Öösh Formation in Mongolia, and probably lived from the Berriasian to Barremian ages of the Early Cretaceous, some 130 million years ago. It was very similar to Microraptor and Sinornithosaurus, indicating that it was a member of their family group. It is only known from partial remains.
