Other relatively predictable adaptations are the development of an obtuse angle between the scapula and coracoid and the loss of the furcula. |
|
In the pectoral girdle, fused clavicles, or a furcula, are now known in many theropods. |
|
However, its feathers, wings, furcula and reduced fingers are all characteristics of modern birds. |
|
Well, it is actually a wishbone, the furcula is the wishbone and it is made up of the clavicles fused together in the middle. |
|
Such analyses have shown that some features considered to be typically avian, such as the furcula, first appeared in carnivorous dinosaurs. |
|
Archaeopteryx was a true bird, because it had a birdlike skull, perching foot, fully-formed flight feathers, a modern-looking elliptical wing, a furcula and avian lung design. |
|
But clavicles are now known from a variety of nonavian dinosaurs, and a fused furcula is present in several nonavian theropods, including allosauroids and tyrannosaurids. |
|
I would like to see if the furcula, or wishbone, is present. |
