Small coelurosaurians are the most diverse dinosaurs, including fellow dromaeosaurid "Velociraptor", troodonts "Byronosaurus" and "Saurornithoides", oviraptors "Citipati", "Khaan", and "Oviraptor", and alvarezsaurs "Mononykus" and "Shuvuuia"; other dinosaurs present included the ceratopsian "Protoceratops" and the ankylosaur "Pinacosaurus". Like other dromaeosaurs, "Mahakala" would have been a small, active, predaceous carnivore.
