Brasileodactylus a genus of pterosaur from the Aptian-age (Early Cretaceous period) lower Santana formation of Chapada do Araripe, Ceará, Brazil.
The genus was named by paleontologist Alexander Wilhelm Armin Kellner in 1984. The genus name means 'pterosaur (literally, [wing] "finger") from Brazil'. The type species is Brasileodactylus araripensis. The specific name refers to the Araripe Plateau. The holotype, MN 4804-V, is the front part of a mandible.
Later remains referred to Brasileodactylus include SMNS 55414, a mandible, and MN 4797–V, the front of a snout and mandible. More complete fossils are BSP 1991 I 27, a fragmentary skeleton, and AMNH 24444, a Шаблон:Convert long skull, with mandible and proximal left wing. The last two specimens have been assigned to a Brasileodactylus sp. indet. by André Jacques Veldmeijer. However, some of the more complete specimens may belong to other pterosaurs, such as Barbosania.[1]
Description
Brasileodactylus was a medium-sized pterosaur with a wingspan of approximately Шаблон:Convert and a body mass of Шаблон:Cvt.[2] It had a long pointed snout and conical teeth that in the extreme front of the jaws were long, thin and forward pointing. Unlike some other Brazilian pterosaurs it had no crest on the snout or lower jaw but might have had one on the back of the skull.[3]
Classification
Kellner first assigned Brasileodactylus to the Ornithocheiridae. In 1991 he changed that to a more cautious Pterodactyloidea incertae sedis. In 2000 he affirmed a close affinity to the Anhangueridae. David Unwin in 2001 considered the form part of Anhanguera but later retracted. Eberhard Frey in 2003 thought it was a species of Coloborhynchus. In 2007 Unwin and David Martill suggested Ludodactylus was a junior synonym of Brasileodactylus.
