Like other maniraptorans, they had long arms that could be folded against the body in some species, and relatively large hands with three long fingers (the middle finger being the longest and the first finger being the shortest) ending in large claws.
Kao i ostali pripadnici Maniraptora, oni su imali duge ruke koje su se kod nekih vrsta mogle sklopiti prema tijelu, kao i relativno velike šake s tri duga prsta (srednji prst je bio najduži, a prvi najkraći) koji su završavali s tri velike pandže.
