Arambourgiania (named after Camille Arambourg) has a confusing history. For much of its early life this azhdarchid was known under a different name, Titanopteryx. During this time, there weren't many good remains of it save for a few neck vertebrae, which were then compared to the vertabrae of Quetzalcoatlus. This estimate yielded a wingspan of 13 m, making this pterosaur the largest flying animal to ever exist.
However, after a while, the genus name Titanopteryx was found to be invalid, as it was found that this name was already occupied, ironically, by a fly. The azhdarchid was then renamed Arambourgiania, after Camille Arambourg, who was the first to realize that this creature was a pterosaur when it was called Titanopteryx. Still as of now, the only fossil material linked to this pterosaur are neck vertebrae.
Still later on, it was found that the estimation of Arambourgiania's wingspan was grossly exaggerated. More recent scans have proven the more accurate estimate of a 7 m wingspan. This was by no means small; it was quite big even for an azhdarchid. It also still owns the record of the largest known neck vertebrae of any pterosaur.
Arambourgiania is known from what is currently Jordan, in the Middle East. It is unknown what other paleofauna lived alongside it at this location. A while later, a second species of Arambourgiania was identified in Pennsylvania, greatly increasing the genus' geographic range. Living near the end of the Cretaceous, it likely lived alongside Deinosuchus, as well as eastern marginocephalians, ankylosaurs, hadrosaurs, and coelurosaurs. Like the other azhdarchids, it likely fed like storks, snatching small creatures from the ground and even wading into water for fish. It went extinct with the rest of the pterosaurs in the KT extinction.
