First North American Occurrence of the Toothed Pteranodontoid Pterosaur Cimoliopterus

  title={First North American Occurrence of the Toothed Pteranodontoid Pterosaur Cimoliopterus},
  author={Timothy S. Myers},
ABSTRACT A new pterosaur species, Cimoliopterus dunni, sp. nov., is described based on a partial rostrum from the upper Cenomanian Britton Formation in the Eagle Ford Group of north-central Texas. The holotype preserves alveoli for a minimum of 26 upper teeth and bears a thin premaxillary crest that begins above the fourth pair of alveoli. The rostrum, characterized by a slight lateral flare, lacks the pronounced lateral expansion found in ornithocheirids and anhanguerids. The tip of the… 
A new species of Coloborhynchus (Pterosauria, Ornithocheiridae) from the mid-Cretaceous of North Africa
Abstract Pterosaur faunas experienced dramatic turnover between the Early and Late Cretaceous, but fossils documenting this transition are rare. The mid-Cretaceous Kem Kem beds of Morocco are one of
An anhanguerian pterodactyloid mandible from the lower Valanginian of Northern Germany, and the German record of Cretaceous pterosaurs
The record of Cretaceous pterosaur remains from Germany is sparse. The material recovered to date includes the fragmentary holotypes of Targaryendraco wiedenrothi and Ctenochasma roemeri, as well as
On Targaryendraco wiedenrothi gen. nov. (Pterodactyloidea, Pteranodontoidea, Lanceodontia) and recognition of a new cosmopolitan lineage of Cretaceous toothed pterodactyloids
The recognition of this clade helps fill the temporal gap between the Anhangueria and Cimoliopterus, and also demonstrates that the diversity of Cretaceous toothed pterosaurs was higher than previously thought.
Reappraisal of Mythunga camara Molnar & Thulborn, 2007 (Pterosauria, Pterodactyloidea, Anhangueria) from the upper Albian Toolebuc Formation of Queensland, Australia
The classification of Mythunga within Anhangueria indicates that this clade was widespread, and perhaps achieved a global distribution by the late Early Cretaceous.

ABSTRACT The Azhdarchidae have come to be known as the most diverse clade of Late Cretaceous pterosaurs and the largest flying creatures in existence. Since the erection of the taxon nearly four
A large pterodactyloid pterosaur from the Late Cretaceous Ferron Sandstone of Utah
Abstract Three associated incomplete wing bones of a large pterodactyloid pterosaur from the Ferron Sandstone Member of the Mancos Shale Formation of Utah are described. Based on the morphology of


A portion of pterosaur skull from the Romualdo Member of the Santana Formation of north-east Brazil provides new data on the mor- phology and ontogeny of azhdarchoid pterOSaur cranial crests, and Tupuxuara is found to be the sister-taxon to Azhdarchidae.
First record ofColoborhynchus (Pterosauria) from the Santana Formation (Lower Cretaceous) of the Chapada do Araripe, Brazil
The anterior tips of associated upper and lower jaws of a pterosaur from the Lower Cretaceous of Brazil are described and assigned to the taxonColoborhynchus in the family Ornithocheiridae. It is
The world's largest toothed pterosaur, NHMUK R481, an incomplete rostrum of Coloborhynchus capito (Seeley, 1870) from the Cambridge Greensand of England

Description of Coloborhynchus spielbergi sp. nov. (Pterodactyloidea) from the Albian (Lower Cretaceous) of Brazil.
A new species of pterosaur, Coloborhynchus spielbergi sp. nov. (Pterodactyloidea), from the Romualdo Member (Albian) of the Santana Formation is described. The type consists of the skull, mandible
Discovery of a Rare Pterosaur Bone Bed in a Cretaceous Desert with Insights on Ontogeny and Behavior of Flying Reptiles
The available information suggests that this species was gregarious, living in colonies, and most likely precocial, being able to fly at a very young age, which might have been a general trend for at least derived pterosaurs.
An overview of the pterosaur assemblage from the Cambridge Greensand (Cretaceous) of Eastern England
The Cambridge Greensand pterosaur assemblage is similar to a slightly younger, but much smaller assemblages from the Lower Chalk of England and shares some elements, such as ornithocheirids, in common with many other late Early and early Late Cretaceous assemblelages.
Pterosaur diversity and faunal turnover in Cretaceous terrestrial ecosystems in China
Two new pterosaurs that are referred to European groups previously unknown in deposits of northeastern China are reported, showing a wide range of groups including both primitive and derived forms that are not matched by any other deposit in the world.
A New Ornithocheirid Pterosaur from the Upper Cretaceous (Cenomanian—Turonian) Eagle Ford Group of Texas
North American pterosaurs are edentulous with the exception of Coloborhynchus (Lee, 1994). In contrast, toothed pterosaurs be longing to the Ornithocheiridae are widely distributed and abun dant in
Taxonomic review of the Ornithocheirus complex (Pterosauria) from the Cretaceous of England
Investigation of the primary literature confirmed that Criorhynchus should be considered an objective junior synonym of Ornithocheirus, and a cladistic analysis demonstrates that Anhangueridae lies within a newly recognized clade, here named AnHangueria, which also includes the genera Cearadactylus, Brasileodactyls, Ludodactelus, and Camposipterus.

Phylogenetic analysis of all Texas pterosaurs that can be coded for more than one character confirms that these species are distinct from others and occupy phylogenetic positions close to their original classifications.
