A new gnathosaurine (Pterosauria, Archaeopterodactyloidea) from the Late Jurassic of Portugal [PDF]

open access: yesPeerJ, 2023
An incomplete, yet remarkably-sized dentated rostrum and associated partial cervical vertebrae of a pterosaur (ML 2554) were recently discovered from the Late Jurassic (Late Kimmeridgian-Early Tithonian) Lourinhã Formation of Praia do Caniçal, of central

Seazzadactylus venieri gen. et sp. nov., a new pterosaur (Diapsida: Pterosauria) from the Upper Triassic (Norian) of northeastern Italy [PDF]

open access: yesPeerJ, 2019
A new non-monofenestratan pterosaur with multicusped dentition, Seazzadactylus venieri, is described from the Upper Triassic (middle-upper Norian) of the Carnian Prealps (northeastern Italy). The holotype of S. venieri preserves a complete mandibular and

Development and evolution of the notarium in Pterosauria [PDF]

open access: yesJournal of Anatomy, 2020
AbstractThe notarium is the structure formed by fusion of the dorsal vertebrae which occurred independently in pterosaurs and birds. This ankylosis usually involves two to six elements and in many cases, also includes the last cervical vertebra. Fusion can occur in different degrees, uniting the vertebral centra, the neural spines, the transverse ...

Comparative analysis of the vertebral pneumatization in pterosaurs (Reptilia: Pterosauria) and extant birds (Avialae: Neornithes) [PDF]

open access: yesPLoS ONE, 2019
Birds and pterosaurs have pneumatic bones, a feature likely related to their flight capabilities but whose evolution and origin is still poorly understood.

A REEXAMINATION OF FOUR PROLACERTIFORMS WITH IMPLICATIONS FOR PTEROSAUR PHYLOGENESIS

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2000
Traditionally, pterosaurs have been included within the Archosauriformes and many contemporary workers consider the Pterosauria the sister group to Lagosuchus, Scleromochlus and the Dinosauria.

Testing pterosaur ingroup relationships through broader sampling of avemetatarsalian taxa and characters and a range of phylogenetic analysis techniques [PDF]

open access: yesPeerJ, 2020
The pterosaurs first appear in the fossil record in the middle of the Late Triassic. Their earliest representatives are known from Northern Hemisphere localities but, by the end of the Jurassic Period, this clade of flying reptiles achieved a global ...

A new early monofenestratan pterosaur from the Mörnsheim Formation of southern Germany [PDF]

open access: yesPeerJ
A number of new early monofenestratan pterosaurs have recently been described from the Late Jurassic Mörnsheim Formation of Southern Germany, greatly expanding our knowledge of the diversity and evolution of this group.

The oldest monofenestratan pterosaur from the Queso Rallado locality (Cañadón Asfalto Formation, Toarcian) of Chubut Province, Patagonia, Argentina [PDF]

open access: yesRoyal Society Open Science
As the first group of tetrapods to achieve powered flight, pterosaurs first appeared in the Late Triassic. They proliferated globally, and by the Late Jurassic through the Cretaceous, the majority of these taxa belonged to the clade Monofenestrata (which

Reconstruction of the adductor chamber and predicted bite force in pterodactyloids (Pterosauria)

open access: yesZoological Journal of the Linnean Society, 2021
Abstract The reconstruction of jaw muscles is critical in establishing potential cranial functions; however, myological studies of extinct groups that have no descendants are difficult to perform and test. This is particularly true for pterosaurs, a group of extinct flying reptiles that present a plethora of cranial morphologies ...

Review of taxonomy, geographic distribution, and paleoenvironments of Azhdarchidae (Pterosauria)

open access: yesZooKeys, 2014
The taxonomy, geographic distribution, and paleoenvironmental context of azhdarchid pterosaurs are reviewed. All purported pteranodontid, tapejarid, and azhdarchid specimens from the Cenomanian Kem Kem beds of Morocco are referred to a single azhdarchid ...
