Abstract

Extensive bulk-sampling of the continuous K-Pg succession at Byala (Central Tethys) provides high-resolution insights into elasmobranch responses to the end-Cretaceous mass extinction of a deep-marine environmental setting. The studied section represents a rhythmic alternation of marls and marly limestones of the Byala Formation, which shows exceptionally well-preserved Milankovitch cyclicity in combination with a deepening-upward trend. The sampled interval comprises one horizon from the uppermost Maastrichtian (Zone CC26), the boundary clay, and five horizons from the lowermost Danian (Zone NP1), which combined yielded a total of 535 elasmobranch teeth. The Maastrichtian assemblage is moderately diverse but strongly dominated by squaliform sharks, including Centrophoridae, Somniosidae, and Etmopteridae. Although most teeth are poorly preserved, limiting accurate estimates of original diversity, several genera typical of deep-marine Maastrichtian environments (e.g., Deania, Centrodeania, Cretascymnus, Protoxynotus, Incognitorapax) were recovered. The sampled Danian interval shows higher elasmobranch diversity compared to the undisturbed pre-extinction environment of the Maastrichtian and a pronounced faunal turnover is described, which is marked by the appearance of Hexanchiformes (Chlamydoselachidae, Hexanchidae), Lamniformes (Carchariidae, Mitsukurinidae), and Carcharhiniformes (Triakidae). The Danian assemblages include teeth of Squalidae (Squalus) and Dalatiidae (Angoumeius), with the latter extending its fossil record into the earliest Paleocene and now spanning from the Danian to the Middle Miocene. Notably, Cretascymnus is reported for the first time in the Danian, indicating that this genus survived the end-Cretaceous extinction event. Comparison with previously studied K-Pg successions from the Northern Tethyan and Boreal realms indicates that elasmobranch extinction intensity was moderate in deep-marine and high-latitude settings, while shallower environments experienced stronger ecological restructuring.

Cunha, Y.T.C., Leite, R.D., Pereira da Silva, L.G. et al. A comprehensive overview of evolutionary relationships and geographic distributions of cownose rays: more valid taxa needing protective measures. Rev Fish Biol Fisheries 36, 37 (2026). https://doi.org/10.1007/s11160-026-10038-3

Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features that allow for reliable differentiation—species identification is primarily based on the shape and arrangement of teeth in the buccal plates. This study aimed to investigate the evolutionary history of the genus Rhinoptera and to explore which evolutionary drivers, such as biogeographic events or behavioral traits, have influenced its diversification.

The authors describe a deep-sea shark (Heptranchias perlo) exhibiting a mosaic pigmentation disorder characterized by the coexistence of hypermelanotic, hypopigmented and amelanotic regions, indicating disruption of normal melanophore distribution and regulation. Histological examination revealed no structural or inflammatory abnormalities, supporting a non-pathological origin of the pigmentation anomaly. In contrast, condition indices indicated pronounced energetic depletion, with reduced condition factor and hepatosomatic index, while lipid extraction and Fourier-transform infrared and ultraviolet–visible spectroscopy revealed substantial depletion and altered composition of hepatic lipid reserves consistent with chronic negative energy balance relative to phenotypically normal conspecifics.

Ribeiro, L.D. & de França, M.A.G. (2025): A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin). Anatomical Record-Advances Integrative Anatomy and Evolutionary Biology, in press
New species: Parvodus graciliani
Abstract: The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic) and the Aliança Formation (Jatobá Basin, Late Jurassic). Here, we describe a new species of Parvodus based on isolated teeth from the Aliança Formation. A taxonomic reassessment of the genus is also presented, integrating its stratigraphic and geographic distribution. The new species provides novel insights into the evolutionary history of Lonchidiidae, with implications for the paleobiogeography of the group and the paleoenvironmental interpretation of the Aliança Formation. Importantly, this record expands the known distribution of Parvodus into the Upper Jurassic of South America.

Canevet, J.-M. (2025): Paralopias follioti n. gen. n. sp., un nouvel Alopiidae Bonaparte, 1838 (Elasmobranchii, Lamniformes) provenant du Serravallien (Miocène Moyen) de Salles (Gironde, France) [Paralopias follioti gen. n. sp. nov., a new Alopiidae Bonaparte, 1838 (Elasmobranchii, Lamniformes) from the Serravallian (Middle Miocene) of Salles (Gironde, France)]. Cossmanniana, 26, 105–121
New genus: Paralopias

New species: Paralopias follioti

Abstract:

Within the order Lamniformes Berg, 1958, the family Alopiidae Bonaparte, 1838 includes three distinct genera of sharks, Alopias Rafinesque, 1810; Anotodus Le Hon, 1871; Usakias Zhelezko & Kozlov, 1999, the former being the only extant one. In this study, we will add the new genus Paralopias nov. gen. which enables us to classify teeth with a peculiar morphology which is distinct from other alopiids. The type species, Paralopias follioti n. sp. was found in the fossiliferous sands in the vicinity of Salles (Aquitaine Basin, France; Serravallian NN6 zone of Martini (1971). This species can easily be distinguished from the other alopiids by the broadness of its cusp which is slightly bent toward the commissure whilst the edge of the cusp is continuous above the root lobes. The lingual side of the root bears a nutrient groove which is reduced to a single foramina, and the lobes are highly elongated and divergent. We include Paralopias alabamensis (White, 1956) n. comb. of the Priabonian (Upper Eocene) of Alabama (United States) in this new genus. Paralopias follioti n. gen. n. sp. went unnoticed by paleoichtyologists because of its short stratigraphic occurrence, during the Serravallian, which is poorly represented in the fossil record. Furthermore, its pelagic habitat explains its scarcity in the fossil strata of the neritic zone. Its presence on the other side of the Atlantic Ocean (Costa Rica) at the same period seems to confirm this hypothesis.

New species: Hemionchos arthanai
Abstract: 

Trypanorhynch cestodes were identified in the stomach and spiral valve of Mobula thurstoni (Lloyd) from Lombok Strait, Bali, Indonesia. This study includes the description of Hemionchos arthanai sp. nov. (Cestoda: Eutetrarhynchidae). New site and locality records were established for H. striatus Campbell and Beveridge, 2006, H. mobulae Campbell and Beveridge, 2006, Mobulocestus Campbell and Beveridge, 2006, Nybelinia balinensis Palm, Palm and Haseli, 2019, and Parachristianella campbelli Schaeffner and Marques, 2018. Hemionchos arthanai sp. nov. can be distinguished from the other Hemionchos species due to its smooth scolex surface lacking transverse annulations, the configuration of its five metabasal hooks per row where the hooks 1–4 (1´–4´) possess characteristic cavities, and its basal armature. The basal armature consists of two rows of enlarged uncinate hooks devoid of cavities, followed by three rows of slender uncinate to spiniform hooks without cavities, and three rows of conical, dorsoventrally flattened, falcate hooks with a strongly recurved mucronate tip. Although the life cycle of H. arthanai sp. nov. is unknown, euphausiaceans are expected to serve as intermediate hosts. This assumption is supported by the fact that H. mobulae has been detected in euphausiaceans, which are prey items for manta rays.

A “ghost” great white shark just reignited a Mediterranean mystery

Date:

Summary:

A rare encounter with a juvenile great white shark caught by fishermen in April 2023 has reignited scientific interest in the mysterious population of these apex predators in the Mediterranean Sea. By reviewing records spanning more than 160 years, researchers found that great whites still appear sporadically in Spanish Mediterranean waters, suggesting the population—though elusive and declining—has not vanished. The discovery of a young shark raises an intriguing possibility: these legendary predators may still be reproducing in the region.

Scientists just discovered bull sharks have friends

University of Exeter

Summary:

Bull sharks may have a reputation as lone hunters, but new research reveals they actually form social bonds and even have preferred “friends.” After six years of observing 184 sharks in Fiji, scientists discovered these animals don’t just mix randomly—they choose companions, swim together, and even follow one another in coordinated ways.
