New vertebrate microfossils expand the diversity of the chondrichthyan and actinopterygian fauna of the Maastrichtian–Danian Hornerstown Formation in New Jersey [PDF]
Acta Palaeontologica PolonicaThe abundance of shark and actinopterygian fossils in the Cretaceous and Paleogene strata of the Atlantic Coastal Plain is well documented; but much remains unknown about the survivorship patterns of these major components of shallow marine faunas in the

Environmental DNA, Volume 8, Issue 4, July‐August 2026.Mangrove estuaries are a key ecosystem for coastal fishery resources, especially in developing nations such as Malaysia. Using identical sampling points and duration for both eDNA metabarcoding and conventional sampling, fish community analyses highlight shared and unique taxa, variable taxonomic resolution, and the complementarity of eDNA ...

Offspring Size Resolves a Population Growth Paradox in Rays and Skates
Fish and Fisheries, Volume 27, Issue 4, Page 927-941, July 2026.ABSTRACT The maximum intrinsic population growth rate, rmax, is a key determinant of sustainable fishing limits and is increasingly used in risk assessments. We previously showed how the rmax of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller‐bodied species and those in warmer, shallower ...

Zoological Letters, 2019 The dentition in extant holocephalans (Chondrichthyes) comprises three pairs of continuously growing dental plates, rather than the separate teeth characterizing elasmobranchs.

Journal of Anatomy, Volume 249, Issue 1, Page 127-140, July 2026.Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.
