Review of taxonomy, geographic distribution, and paleoenvironments of
Azhdarchidae (Pterosauria).
ZooKeys 432: 1–107
doi: 10.3897/zookeys.432.7913

The taxonomy, geographic distribution, and paleoenvironmental context
of azhdarchid pterosaurs are reviewed. All purported pteranodontid,
tapejarid, and azhdarchid specimens from the Cenomanian Kem Kem beds
of Morocco are referred to a single azhdarchid taxon, Alanqa saharica.
The four proposed autapomorphies of Eurazhdarcho langendorfensis from
the lower Maastrichtian Sebeş Formation of Romania are based on
misinterpretations of material and this taxon is likely a subjective
junior synonym of Hatzegopteryx thambema. Among 54 currently reported
azhdarchid occurrences (51 skeletal remains and 3 tracks) 13% are from
lacustrine deposits, 17% from fluvial plain deposits, 17% from coastal
plain deposits, 18% from estuarine and lagoonal deposits, and 35% from
costal marine deposits. Azhdarchids likely inhabited a variety of
environments, but were abundant near large lakes and rivers and most
common in nearshore marine paleoenvironments.
