Revision of the Cretaceous shark Protoxynotus (Chondrichthyes, Squaliformes) and early evolution of somniosid sharks

open access: yesCretaceous Research, 2022
Due to the peculiar combination of dental features characteristic for different squaliform families, the position of the Late Cretaceous genera Protoxynotus and Paraphorosoides within Squaliformes has long been controversial. In this study, we revise these genera based on previously known fossil teeth and new dental material. The phylogenetic placement

Hopping Hotspots Shaped the Global Biogeography and Diversification of Orectolobiform Sharks

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim In marine biogeography, many clades exhibit their greatest species richness in the Central Indo‐Pacific region, which includes the Indo‐Australian Archipelago. However, there is no consensus that this region was the ancestral cradle of clade's species richness.

Reproductive biology, distribution and abundance of Squalus megalops (Macleay, 1881) and Squalus mitsukurii (Jordan & Snyder, 1903) off southern Brazil, southwest Atlantic

open access: yesJournal of Fish Biology, Volume 107, Issue 3, Page 824-836, September 2025.
Abstract Squalus megalops and Squalus mitsukurii are recognized as the most abundant Squalus species in the southern Brazil region. Currently, S. megalops is listed as ‘least concern’ (LC) and S. mitsukurii as ‘endangered’ (EN). However, at the regional level, both species are classified as ‘data deficient’ – DD, due to the lack of population local ...
