High Quality Content by WIKIPEDIA articles! "Tonouchisaurus" (meaning "Tonouchi lizard") is the informal name given to an as yet undescribed genus of dinosaur from the Early Cretaceous Period. It was a theropod which lived in what is now Mongolia. The suggested "type species", "Tonouchisaurus mongoliensis", was coined by Barsbold in 1994. It was notably small: less than three feet in length. It may have been a tyrannosaurid, judging by the known skeletal elements, which include only limb bones. These limb bones include "a complete didactyl manus and complete pes, as well as other limb bones" (Olshevsky 1996).
