Aerotitan is a

azhdarchid pterosaur known from the Late Cretaceous period (Maastrichtian stage) of what is now the Allen Formation of the Neuquén Basin in northern Patagonia, Argentina.[1]

Discovery and naming

The

Titan, in reference to the fact the species represents a large flying reptile. The specific name refers to its provenance from South America.[1]

The holotype, MPCN-PV 0054, has been recovered near the Bajo de Arriagada site, in Patagonia, from a layer of the upper Allen Formation. It consists, according to the original description, of a partial rostrum with a preserved length of 264 millimeters (10.4 in). This snout is elongated and transversely compressed and the jaws are toothless. The wingspan has been estimated as at least 5 meters (16 ft).[1]

In 2021, a study concluded that the specimen represented, not the upper jaws but the lower jaws.[2]

Taxonomy

Aerotitan has been assigned to the

thalassodromid, sister taxon to Alanqa (a pterosaur also assigned as an azhdarchid), however, such assignment is not well-supported.[3]
The cladogram of their analysis is presented below:

Dsungaripteromorpha

Dsungaripteridae

Thalassodromidae

Tupuxuara longicristatus

Tupuxuara leonardii

Thalassodromeus sethi

Alanqa saharica

Aerotitan sudamericanus

Conversely, a 2021 study by Rodrigo Pêgas and colleagues noted dissimilarities between it and thalassodromines and supported an azhdarchid identity.[2]
