A new species of pterosaur, Maaradactylus kellneri gen. nov., sp. nov.
(Archosauria: Pterosauria) from the Romualdo Formation
(Aptian/Albian), is herein described. The specimen (MPSC R 2357) was
found at Sítio São Gonçalo, Santana do Cariri city (State of Ceará,
northeast Brazil) and consists of the skull, atlas and axis, and
represents one of the largest skulls of the Anhangueridae from the
Araripe Basin described. The autapomorphies of the new pterosaur
include the following characters: a premaxillary sagittal crest that
is relatively long and high, beginning at the anterior part of the
skull (rostrum) and extending to the 22nd pair of alveoli, not
covering the nasoantorbital fenestra or the choanaes, and also the
presence of 35 pairs of alveoli; smooth palatal ridge, which starts on
the 5th pair of alveoli and ends on the 13th pair; palate is convex
shaped in the anterior region; choanae not extending laterally; small
and convex palatal elevation; the 5th, 6th and 7th alveoli smaller
than the 4th and 8th; the alveoli decreasing in size from the 9th to
the 12th and increasing from the 13th to 18th, and from the 18th to
the 35th they are arranged in triplets. Furthermore, the lateral
surface of the premaxillary crest shows grooves and tridimensional
structures that may have housed blood vessels.
