An international research team comprising of paleontologists from China, the United States, Germany and Australia has announced the discovery of a tridactyl footprint, 10.2 milimeters long and 9.6mm wide, of a tiny dinosaur. The footprint, found in Zigong, a city in southwest China's Sichuan Province, is the smallest dinosaur track to be found in China to date.

The footprint reportedly belongs to Grallator, a non-avian theropod whose footprint's length is usually less than 15 centimeters. They estimated it was left by a newborn dinosaur with a body length of about 12 cm, about the size of a sparrow.
