metacarpus

The four bones of the wing finger measure, from the point where the first bone bends upon the metacarpus, less than 18 inches.

The chief point of variation from the Pterodactyle wing is in the relative length of the metacarpus in Dimorphodon.

The whole finger is preserved in other specimens straightened out so as to be in line with the metacarpus.

The manner in which the third (large) metacarpus is fractured, largely determines the outcome in any given case.

In simple fracture, the metacarpus is covered with enough cotton to pad the parts, and this is retained in position by bandages.
