Uncinate Processes

Uncinate Processes

 

spurs of the thoracic ribs—bony in birds and certain fossil reptiles and cartilaginous in existing reptiles (crocodiles, the tuatara). The uncinate process of a rib overlaps the next rib behind. Uncinate processes strengthen the thorax, which is especially important in flight. For this reason they are most highly developed in flying birds.
