Digital restoration of the pectoral girdles of two Early Cretaceous birds and implications for early-flight evolution
By A Mystery Man Writer
Description
New digital restorations indicate that the structure and function of the shoulder joint were highly variable among Early Cretaceous birds, with such key features as the configuration of the triosseal canal and the nature of scapula-coracoid articulation showing considerable diversity.
