Pteranodontoids consist of a diverse and cosmopolitan clade of
Cretaceous pterodactyloid pterosaurs. In the Jiufotang Formation
(Lower Cretaceous, Aptian) of northeastern China, pterodactyloids are
represented by azhdarchoids and pteranodontoids, including
istiodactylids and anhanguerians. Here, we describe a new pterosaur
from this unit that represents a new species of toothed
pteranodontoid. Its overall morphology is consistent with other
toothed pteranodontoids but shows some interesting features such as
the orbit being more ventrally positioned than in all other species
from this clade. It differs markedly from all other pterosaurs from
this unit, including Liaoningopterus, Guidraco and Ikrandraco, with
which the new taxon is possibly related. In addition to the
description of the new taxon, we also describe the anhanguerid
Liaoningopterus gui in more detail. The new species, Liaoningopterus
gui, Guidraco venator and Ikrandraco avatar, are large pterosaurs with
very distinct tooth morphologies, suggesting that they had different
prey preferences, partially explaining how the Jiufotang Formation
could bear such a high diversity of pterosaur species.
