Mononykus
Mononykus (/məˈnɒnɪkəs/ mə-NON-i-kəs, sometimes /ˌmɒnoʊˈnaɪkəs/ MON-oh-NY-kəs; meaning "one claw") is a genus of alvarezsaurid dinosaur that lived during the Late Cretaceous in what is now Asia on the Nemegt Formation, about 70 million years ago.
Mononykus was a very small theropod, estimated around 1 to 1.2 metres (3.3 to 3.9 ft) in length with a weight of 3.5 kilograms (7.7 lb). As in Shuvuuia, Mononykus likely developed a shaggy feathering. It was lightly built with long, thin legs and highly reduced and specialized forelimbs that were likely used for foraging termite mounds or other insect colonies.
