Discovery and naming

The type species Aerotitan sudamericanus was named and described in 2012 by Fernando Novas, Martin Kundrat, Federico Agnolín, Martin Ezcurra, Per Erik Ahlberg, Marcelo Isasi, Alberto Arriagada and Pablo Chafrat. The generic name is derived from Greek ἀήρ, aer, "air", and 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 of a partial rostrum with a preserved length of 264 millimetres (10.4 in). This snout is elongated and transversely compressed and the jaws are toothless. The wingspan has been estimated as at least 5 metres (16 ft).[1]

Taxonomy

Aerotitan has been assigned to the Azhdarchidae. If correct, this would make it the first unambiguous azhdarchid from South America.[1] However, a more study published in 2018 classified the genus as a thalassodromid.[2]

gollark: Coronavirus caused birds. It was designed to alter people's memories so they remember B. I. R. D. surveillance drones as if they were real animals, but mutated and became dangerous.
gollark: Mostly. Some smaller services are run for free without data mining and whatnot because they're cheap to run, and there's plenty of trustworthy FOSS software.
gollark: The definition of "4G" involved some unreasonably high standard, so we got "LTE" instead.
gollark: It's actually the other way round for 4G as far as I know.
gollark: Ah yes, of course, they would want to keep its evil 5G nature secret until the world was ready.
