名词 n.
英文释义
名词 n.
-
A derived trait that is shared by two or more taxa of shared ancestry.
— Another supposed synapomorphy of Rhamporhynchidae + Pterodactyloidea presented by Unwin (1995) is the subequal length of metacarpals I–III. In all non-pterodactyloid specimens where this region is known metacarpals I–III are about the same length. Therefore this feature cannot be used as a synapomorphy of Rhamporhynchidae + Pterodactyloidea.
