The Late Cretaceous chondrichthyan fauna of the Elbtal Group (Saxony, Germany) [PDF]
Upper Cretaceous (upper Cenomanian–lower Coniacian) marine strata of Saxony, eastern Germany, are mainly known for their rich invertebrate fauna, but have also yielded various vertebrate remains. The Saxonian Cretaceous marine strata, predominantly sand-

Chondrichthyan Fauna from the Pirabas Formation, Miocene of Northern Brazil, with Comments on Paleobiogeography [PDF]
The chondrichthyan fauna from the Pirabas Formation is redescribed. Only thirteen nominal taxa are considered valid. From these taxa, ten were reassigned to extant taxa (Carcharhinus sorrah, Carcharhinus perezii, Galeocerdo cuvier, Rhizoprionodon ...

Electroreception in marine fishes: chondrichthyans [PDF]
Abstract Electroreception in marine fishes occurs across a variety of taxa and is best understood in the chondrichthyans (sharks, skates, rays, and chimaeras). Here, we present an up‐to‐date review of what is known about the biology of passive electroreception and we consider how electroreceptive fishes might respond to electric and ...

The Shark Basal Hypothalamus: Molecular Prosomeric Subdivisions and Evolutionary Trends
The hypothalamus is a key integrative center of the vertebrate brain. To better understand its ancestral morphological organization and evolution, we previously analyzed the segmental organization of alar subdivisions in the catshark Scyliorhinus ...
