Sexual dimorphism in chain catshark, Scyliorhinus retifer (Elasmobranchii, Carcharhiniformes, Scyliorhinidae): Morphology and dermal denticles evidence [PDF]
Acta Ichthyologica et PiscatoriaWe studied the morphological variation of the chain dogfish, Scyliorhinus retifer (Garman, 1881), to demonstrate sexual dimorphism based on 15 adult males {434–557 mm total length (TL)} and 10 adult females (437–556 mm TL) captured in the southern Gulf ...

Three-dimensional fossils of a Cretaceous collared carpet shark (Parascylliidae, Orectolobiformes) shed light on skeletal evolution in galeomorphs [PDF]
Royal Society Open ScienceA rich fossil record of teeth shows that many living shark families’ origins lie deep in the Mesozoic. Skeletal fossils of the sharks to whom these teeth belonged are far rarer and when they are preserved are often flattened, hindering understanding of ...

Apristurus iterum, a new shark discovered based on egg case morphology and sequence data obtained from a formalin-fixed specimen. [PDF]
J Fish BiolAbstract Apristurus iterum, a new species of deepwater catshark, is described from northeastern Australia. The new species is diagnosed through examination of its unique egg case morphology based on a single whole gravid female specimen and 10 egg cases deposited in different Australian ichthyological collections.
