“…The specimen studied in this work was found in a limestone layer from the lower part of the Middle Blesa sequence, known as Morenillo member. Even though most of the Blesa Formation is deposited in a continental environment with abundant terrestrial tetrapod remains, the Middle Blesa sequence was deposited in a coastal environment rich in marine fossils as mollusc bivalves, but where isolated remains of actinopterygians, chondrichthyans, chelonian plates, teeth and cranial and postcranial elements of crocodylomorphs are also found 13,15 , as well as teeth and vertebral centra belonging to plesiosaurs 16 .Figure 1Geographical and geological location of the Los Quiñones site in the Blesa Formation.

“…Los Quiñones is close to the village of Obón (Teruel, Spain), located in the northeast of the Iberian Peninsula (Fig. 1 ), and placed within the upper part of the Blesa Formation, which is considered as Barremian in age 13 , 14 . The Blesa Formation is part of the syn-rift sedimentation in the Iberian Basin during the Early Cretaceous, and has been recently divided in 3 genetic stratigraphic sequences: Lower, Middle, and Upper Blesa sequences 14 .…”
The pterosaur record from the Iberian Peninsula is mostly scarce and undefined, but in the last few years some new taxa have been described from different Lower Cretaceous sites of Spain. Here we describe a new genus and species of toothed pterodactyloid pterosaur from the Barremian of the Iberian Peninsula, Iberodactylus andreui gen. et sp. nov., that shows a close and rather unexpected relationship with Hamipterus tianshanensis from China. A review of the phylogenetic relationships of the Anhangueria reveals a new family of pterodactyloid pterosaurs, the Hamipteridae fam. nov. being recovered as sister-group of the Anhangueridae. This latter clade can be in turn divided into the new clades Anhanguerinae and Coloborhynchinae. The close relationships of Iberodactylus and Hamipterus shows an interesting palaeobiogeographical correlation between the Chinese and Iberian pterosaur faunas during the Barremian (Lower Cretaceous). The discovery of Iberodactylus strongly suggests that the clade Anhangueria has clear ancestral ties in eastern Laurasia.
