Paleobiology and paleobiogeography of sclerorhynchid sawfishes (Chondrichthyes, Batomorphii)
Spanish Journal of Palaeontology, 2021 Sclerorhynchid sawfishes are a monophyletic group of Cretaceous selachians. They resemble modern sawfishes in the outer morphology and by having a hypertrophic rostral cartilage armed with lateral rows of spines.

Updated checklist of Azores Chondrichthyes (Vertebrata: Gnathostomata) [PDF]
Biodiversity Data Journal, 2021 Several lists of marine fish from Azores have been published in the past. Most of those publications are difficult to access on line and several were not published in peer-reviewed journals. This checklist updates all the chondrichthyan records for the Azores Exclusive Economic Zone (EEZ), according to the most recent taxonomic classification

The whale shark genome reveals patterns of vertebrate gene family evolution
eLife, 2021 Chondrichthyes (cartilaginous fishes) are fundamental for understanding vertebrate evolution, yet their genomes are understudied. We report long-read sequencing of the whale shark genome to generate the best gapless chondrichthyan genome assembly yet ...

Multiple paternity and hybridization in two smooth-hound sharks [PDF]
, 2015 Multiple paternity appears to be a common trait of elasmobranch mating systems, with its occurrence likely driven by convenience, due to females seeking to minimize the stress of male harassment.

A Mutual Information Based Sequence Distance For Vertebrate Phylogeny Using Complete Mitochondrial Genomes [PDF]
, 2007 Traditional sequence distances require alignment. A new mutual information based sequence distance without alignment is defined in this paper. This distance is based on compositional vectors of DNA sequences or protein sequences from complete genomes ...
