Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei)

Journal of Anatomy, EarlyView.
This article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...

Revealing elasmobranch diversity across the Cretaceous-Paleogene boundary in the Central Tethys (Byala, Bulgaria) [PDF]

Fossil Record
Extensive bulk-sampling of the continuous K-Pg succession at Byala (Central Tethys) provides high-resolution insights into elasmobranch responses to the end-Cretaceous mass extinction of a deep-marine environmental setting. The studied section represents

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

First Documented Courtship Behavior between Mobula birostris and M. alfredi at a Coral Reef Cleaning Station in Misool, Raja Ampat

Diversity
Though a previous study in Sudan confirmed the existence of a living hybrid of an oceanic manta ray (Mobula birostris) and a reef manta ray (M. alfredi), courtship behaviors between the two closely related species have never been documented.
