Scansor are sparrow-sized animal that shows adaptations in the foot indicating an arboreal (tree-dwelling) lifestyle. It is notable for its “primitive” non-perforated hip socket, and pubis (hip bone) which points forward, unlike some advanced maniraptorans. One distinctive feature of Scansor is its elongated third finger, which is the longest on the hand (nearly twice as long as the second finger), and may be analogous to the insect-digging finger of the mammalian aye-aye. Scansor is also notable for its wide, rounded jaws. The lower jaw contained at least twelve teeth, larger in the front of the jaws than in the back. The lower jaw bones may have been fused together, a feature otherwise known only in the oviraptorosaurs. The tail was long, six or seven times the length of the femur, and ended in a fan of feathers. It also has an unusually large first toe.
Scansor are insect hunting carnivores.
Scansor are found both alone and in mated pairs or small families while their offspring develop.
