Ferrodraco ("Iron Dragon" after the ironstone the fossil was found in) is an extinct genus of anhanguerid pterosaur known from the Late Cretaceous Winton Formation of Queensland, Australia,[1] containing the single species F. lentoni.
It is the most complete pterosaur fossil from Australia, being known from the holotype specimen AODF 876, consisting primarily of the anterior portion of the skull and dentary, cervical vertebral centra and a partial wing.
A recent study also recovered Ferrodraco as sister taxon to Mythunga, but both placed within the family Anhangueridae, more specifically within the subfamily Tropeognathinae.
[2] The generic name is derived from the Latin ferrum, "iron", and draco, "dragon", in reference to the fact that the skeleton was found in ironstone.
The specific name honors the late mayor of Winton Shire, Graham Thomas 'Butch' Lenton, for his work for the local community and his support for the Australian Age of Dinosaurs.
The holotype, AODF 876, was found in a layer of the Winton Formation dating from the Cenomanian - lower Turonian, about ninety-six million years old.
The first analysis found Ferrodraco within the clade Ornithocheirae, more precisely within the subfamily Ornithocheirinae as the sister species of Mythunga, another Australian pterosaur from somewhat older layers.
[1] A more recent study made in 2020 by Borja Holgado and Rodrigo Pêgas placed Ferrodraco within the family Anhangueridae, more specifically within the subfamily Tropeognathinae, although still the sister taxon to Mythunga.
[5] In 2022, Pentland et al. published a detailed description of Ferrodraco (particularly the post-cranial skeleton) and a renewed phylogenetic appraisal that unequivocally demonstrated that it belongs in the family Anhangueridae as proposed by Holgado and Pêgas.
This study suggested that the precise position of Ferrodraco and Mythunga within Anhangueridae still remains uncertain, and that the diversity of Australian pterosaur fauna has been greatly underestimated.
