The furcula (Latin for "little fork"; pl.: furculae) [a] or wishbone is a forked bone found in most birds and some species of non-avian dinosaurs, and is formed by the fusion of the two clavicles. [1] In birds, its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight.
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.

The furcula, or furca is a forked, tail-like appendage. It is present in most species of springtails , and in them it is attached ventrally to the fourth abdominal segment. The organ most often is present in species of Collembola that lives in the upper soil layers where it is used for jumping to avoid predators. [ 1 ]
This stylised bird skeleton highlights the synsacrum Pelvis of a Gull; formed by the Synsacrum (fused vertebrae placed centrally) and the two innominate bones either side. The synsacrum is a skeletal structure of birds and other dinosaurs, in which the sacrum is extended by incorporation of additional fused or partially fused caudal or lumbar ...

Praeornis, from the Oxfordian-Kimmeridgian of Kazakhstan, may have been the earliest known member of Enantiornithes according to Agnolin et al. (2017). [13]Birds with confidently identified characteristics of Enantiornithes found in Albian of Australia, Maastrichtian of South America, and Campanian of Mexico (Alexornis [14]), Mongolia and western edge of prehistoric Asia suggest a worldwide ...
The hindmost part of the surangular had a small foramen placed in the same position as similar openings in the mandibles of non-bird theropods and modern birds. The splenial bone was three-pronged (as in some modern birds, but unlike the simple splenial of Archaeopteryx), and its lower margin followed the lower margin of the mandible. There was ...
