The Maniraptora (= "hand robbers") are a group of dinosaurs that includes advanced coelurosaurs and birds (Aves). They are characterized by a special, crescent-shaped bone in the wrist . As a result, a greater mobility of the hand was achieved, which was an important step towards the mobility necessary for bird flight . The feather also developed further within the Maniraptora.

The Maniraptora of the Mesozoic Ages were small and medium-sized animals that had the largest brains compared to body size within the dinosaurs. It is believed that they were intelligent and agile predators.

Internal system

A model of the internal systematics of the Maniraptora according to a recent study gives the following cladogram :
