First Mesozoic Record of the Stingray Myliobatis wurnoensis from Mali and a Phylogenetic Analysis of Myliobatidae Incorporating Dental Characters

The phylogenetic position of the extinct myliobatid Myliubatis wurnoensis is evaluated using osteology and dentition, and it is found that taxa known only from the Cretaceous, Brachyrhizodus and Igdabatis, are highly nested within Myliob atidae.

New interpretations of the skull of a primitive bony fish Erpetoichthys calabaricus (Actinopterygii: Cladistia)

The terminology critical to understanding cranial morphology in polypterids is reviewed and a new description of the skull of E. calabaricus is presented as observed through classical methods of skeletal preparation, X‐radiographic microfocus computed tomography, and 3D‐digital reconstruction.

A Virtual Phytosaur Endocast and Its Implications for Sensory System Evolution in Archosaurs

A comparison with phylogenetically diverse archosaurian endocasts reveals that endocast morphologies are highly conserved within Pseudosuchia, regardless of Bauplan or ecology.

The impacts of comparative anatomy of electric rays (Batoidea: Torpediniformes) on their systematic hypotheses

The Comparative anatomy of the 11 recognized genera within Torpediniformes is described, systematically categorized, and illustrated in a comprehensive photo‐atlas, with one notable exception: a monophyletic Narcininae was never recovered.

Morphology of the anterior vertebral region in elasmobranchs: special focus, Squatiniformes

Investigation of the extinct taxon †Pseudorhina alifera from the Late Jurassic of Solnhofen with extant species of Squatina provide new evidence that members of Squatiniformes possess a basioccipital fovea, suggesting a significant functional, rather than phylogenetic, signal for this feature.

Definitive specimens of Merlucciidae (Gadiformes) from the Eocene James Ross Basin of Isla Marambio (Seymour Island), Antarctic Peninsula

Abstract An isolated partial right dentary (BAS D.515.2) collected by the British Antarctic Survey prompted a re-evaluation of gadiform remains from the La Meseta Formation (conventionally middle…

The synarcual cartilage of batoids with emphasis on the synarcual of Rajidae

Comparison of embryonic specimens with juvenile and mature specimens of other skates indicates that the relative developmental sequence of events is maintained among several taxa within larger clades, and results from exploratory analyses of morphospace and taxonomy reveal that phylogeny explains part, but not all, of the data on the synarcual in Rajidae.

†Tingitanius Tenuimandibulus, a New Platyrhinid Batoid from the Turonian (Cretaceous) of Morocco and the Cretaceous Radiation of the Platyrhinidae

ABSTRACT An exceptionally well-preserved specimen of a batoid from the Turonian (Late Cretaceous) of Morocco has been named as †Tingitanius tenuimandibulus, sp. nov. The fossil has been identified…

Variation of the synarcual in the California Ray, Raja inornata(Elasmobranchii: Rajidae)

Results show that as R. inornata increases in body size, the synarcual becomes more elongate and laterally compressed, and projections of thesynarcual become more pronounced with increasing size as well.
