Шаблон:Short description Шаблон:Speciesbox
Ardeadactylus (from Ardea – meaning "heron", and also a name of a genus of herons – and dactylus, meaning "finger") is an extinct genus of ctenochasmatoid pterosaur known from the Late Jurassic Solnhofen limestone of Bavaria, southern Germany. It contains a single species, Ardeadactylus longicollum, which was originally thought to be a species of Pterodactylus, as P. longicollum.[1]
History
Only two specimens of Ardeadactylus are known to exist currently: SMNS 56603 (earlier SMNS 5802) found in 1874, a specimen from Nusplingen initially thought to belong to the species Pterodactylus suevicus (currently Cycnorhamphus),[2] and the neotype of the species, JME-SOS 2428, a specimen held at Jura Museum in Eichstätt. Other known specimens, including the holotype designated by Christian Erich Hermann von Meyer when he named the type species Pterodactylus longicollum in 1854,[3] were lost during World War II.[1] The original holotype, consisting of the skull, neck and anterior torso, had been found near Eichstätt in 1853 and was that year acquired for the Herzoglich Leuchtenbergische Naturalien-Kabinett by Professor Ludwig Frischmann.[3] Its destruction motivated Peter Wellnhofer to assign a neotype in 1970.[4]
Description
Ardeadactylus is suspected to be a heron–like, long–necked long–legged piscivore.[1] It was similar to Pterodactylus antiquus in its general body form, but seems to have been larger. Bennett (2013) estimated the wingspan of the neotype specimen to be Шаблон:Convert; the referred specimen from the Jura Museum is more or less 10% larger.[1] A. longicollum had fewer, fifteen per jaw, and relatively larger teeth than P. antiquus, possibly indicating that it preyed on larger fish than Pterodactylus.[1]
Classification
In 2017, a phylogenetic analysis by Steven Vidovic and David Martill found Ardeadactylus within the family Aurorazhdarchidae, sister taxon to Aurorazhdarcho. Their cladogram is shown below:[5]
In 2018 however, Nicholas Longrich and colleagues had recovered a different set of relationships for ctenochasmatoids. In their analysis, Ardeadactylus was recovered within the Ctenochasmatidae instead. Their cladogram is shown below.[6] Шаблон:Clade
