Abstract The Neoselachii are a monophyletic group including all of the extant sharks and rays. They underwent rapid diversification throughout the Jurassic and Cretaceous, going from low-diversity assemblages of members of extinct orders in the Late Triassic to diverse assemblages containing representatives of most extant clades by the end of the Cretaceous. The known fossil record of Mesozoic neoselachians is composed largely of isolated teeth, with articulated skeletal remains being known… 
Regional to Global Patterns in Late Cretaceous Selachian (Chondrichthyes, Euselachii) Diversity
ABSTRACT Although selachian fossil remains have been studied for nearly three centuries, little is known about their evolutionary history. Recent studies have suggested different timings of early
Diversity and biogeography patterns of Late Jurassic neoselachians (Chondrichthyes: Elasmobranchii)
Abstract The regional diversity and biogeographic patterns of Late Jurassic neoselachians at genus level in Europe were analysed based on samples and an extensive literature survey of about 40
Development of understanding of the Mesozoic and Cenozoic chondrichthyan fossil record
Abstract Fossils of post-Palaeozoic sharks and rays are common and well known, and have been extensively studied. Early studies, especially the monographic works of Agassiz and Smith Woodward,
A new Early Cretaceous lamniform shark (Chondrichthyes, Neoselachii)
TLDR
It is hypothesized that most pre-Aptian lamniforms belong to an ancient group characterized, amongst others, by a very weak gradient monognathic heterodont dental pattern, and by tearing-type dentition.
A new chondrichthyan fauna from the Late Jurassic of the Swiss Jura (Kimmeridgian) dominated by hybodonts, chimaeroids and guitarfishes
The fossil record of chondrichthyans (sharks, rays and chimaeroids) principally consists of isolated teeth, spines and dermal denticles, their cartilaginous skeleton being rarely preserved. Several
JURASSIC FISHES OF GONDWANA
The Jurassic is an important period for understanding the origin of modern fish faunas, since it saw the first radiation - and in some cases the origin - of most modern groups. In chondrichthyans,
New chondrichthyans characterised by cladodont-like tooth morphologies from the Early Cretaceous of Austria, with remarks on the microstructural diversity of enameloid
TLDR
Two new chondrichthyan genera based on isolated teeth recovered from Valanginian (Early Cretaceous) deep-water deposits of Austria are described, including a total of three new species tentatively assigned to the cladodontomorph families Falcatidae (Cretacladoides ogiveformis gen. and C. noricum sp. nov.) and Ctenacanthidae (Natarapax trivortex gen. et sp.Nov).
Oldest evidence of bramble sharks (Elasmobranchii, Echinorhinidae) in the Lower Cretaceous of southeast France and the evolutionary history of orbitostylic sharks
TLDR
The fossil record is now consistent with the assumption that the Echinorhinidae is the stem group of Squaliformes s.l. and the modern morphology of the first representatives does not support alternative hypotheses.
The Late Jurassic ray Kimmerobatis etchesi gen. et sp. nov. and the Jurassic radiation of the Batoidea
TLDR
Results from parsimony and likelihood phylogenetic reconstruction indicates that the whole-bodied Jurassic batoids Spathobatis, Belemnobatis and Kimmerobatis gen. nov. form their own clade, SpathOBatidae, and do not lend support to a monophyletic “Rhinobatidae”.
Revision of the fossil batomorphs from the Cretaceous of Lebanon, and their impact on our understanding of the early step of the evolution of the clade
TLDR
The attribution of three lebanese shark-like rhinobatids species included into two new genera to Rhynchobatidae are discussed, which possess a combination of primitive characters such as propterygium failing to reach the level of the nasal capsules and pectoral fin posterior corner not reaching thelevel of the pelvic fin.

Selachian faunas from the lowermost Cretaceous Purbeck Group of Dorset, southern England
TLDR
Within the entirely non-marine succession of the Purbeck Group, the beds containing ray teeth also contain molluscs indicative of more saline intervals, and in all of the sampled beds, the hybodont faunas recovered were relatively homogenous.
