Azhdarchidae (from اژدرها (Aždarha), the Persian word for dragon) is a family of pterosaurs known primarily from the late Cretaceous Period, though an isolated vertebrae apparently from an azhdarchid is known from the early Cretaceous as well (late Berriasian age, about 140Ma ago).
Several teeth referable to Lusitanisuchus were also found from Porto Dinheiro, Lourinhã in strata deposited during the Berriasian stage of the Early Cretaceous, extending the temporal range of this taxon by about 15 Ma.
The only known species, P. corneti, was described in 1984 based on a single bone (MTCO-P 1637) interpreted as the distal part of a left femur, found in Early Cretaceous (Berriasian rocks (dating to around 143 mya) from a mine at Cornet near Oradea in northwestern Romania.
There is a possible age difference of perhaps over thirty million years between the Berriasian-Valanginian British and the younger Albian-Cenomanian American form.
