Wenupteryx uzi is the new name (Codorniú and Gasparini 2007) given to the second Jurassic pterosaur discovered in Argentina (Codorniu et al. 2006, Figs 1-4). Formerly it was known from its specimen number, MOZ 3625. Nearly a complete skeleton, sans the skull, is known from scattered and crushed remains. A recent closeup of the lower hind leg (Codorniú et al. 2013) permitted a DGS reconstruction of the pes (Fig. 2) in line with its previous phylogenetic nesting within the germanodactylids, between the BMM private specimen and all higher germanodactylids, seen here (Fig. 3).
Codorniú et al. 2013) considered this a tibiatarsus and the loose tarsals distal tarsals. They did not realize there are no tibiotarsi known among pterosaurs. The loose tarsals here (Fig. 2) are proximal tarsals (astragalus and calcaneum) plus one distal tarsal (likely #4).
Wenupteryx is an important taxon that nests at the base of two higher Germanodactylus clades. One branch leads to dsungaripterids, shenzhoupterids and tapejarids. Another branch leads to elanodactylids, eopteranodontids and pteranodontids. So, it is a very plesiomorphic specimen. No wonder it was hard to originally identify (Codorniu et al. 2006).
We are going to have to take a serious look at all specimens given the genus Germanodactylus and all of the specimens, like Wenupteryx, nesting between them but given other generic names (Fig. 3).
