Results indicate a better fossil record quality for elasmobranchs due to their microfossil‐like fossil distribution and their very low diversity in freshwater systems, whereas freshwater actinopterygians are diverse in this realm with lower preservation potential.

The first detailed comparative description of teeth belonging to most of the living and fossil mobulids is performed, providing clues to the evolutionary history of this clade since the Early Eocene, including the gradual lack in tooth interlocking toward the filter-feeding strategy, whereas the preservation of cusped teeth without feeding function in modern filter-feeder mobulid is interpreted as a tool for precopulatory purposes.

An updated Late Cretaceous selachian fossil record and global standing diversity are presented, and observations on the dentition of a few species (Anomotodon hermani, Cederstroemia, Carcharias latus, Palaeotriakis, Paratriakis) are made.
Squatiniformes (Chondrichthyes, Neoselachii) from the Late Cretaceous of southern England and northern France with redescription of the holotype of Squatina cranei Woodward, 1888

Bulk sampling of phosphate‐rich horizons within the Late Cretaceous of the Anglo‐Paris Basin yielded numerous teeth of members of the Squatiniformes, and a new subgenus Cretascyllium is proposed for species of the genus Squatina with high degree of heterodonty and triangular anterior teeth.

Results indicate that with the exception of high taxonomic ranks (orders), the selachian fossil record is by far imperfect, particularly for generic and post-Triassic data.

An outer-platform cladodontomorph shark tooth assemblage from the Early Cretaceous of southern France is described, increasing the fossil record of this group by circa 120 million years, and shows that this lineage survived mass extinctions most likely by habitat contraction, using deep-sea refuge environments during catastrophic events.

This study reveals new insights in the understanding of character distribution among batomorphs and sets a framework for tackling global chondrichthyan tooth enameloid evolution.
The first articulated specimen of the Cretaceous mackerel shark Haimirichia amonensis gen. nov. (Haimirichiidae fam. nov.) reveals a novel ecomorphological adaptation within the Lamniformes…
The articulated specimen of H. amonensis reveals a novel ecomorphological specialization within the Lamniformes, adding to the high disparity observed within this order.
