In this short communication, we describe the first reported case of an in-situ observation and subsequent sampling of a fossil Otodus megalodon tooth from a deep-sea locality in the Pacific Ocean (14.11332°N, 167.39357°W; 3090 m depth). The additional documentation of its location prior to collection allows for tentative conclusions on surrounding factors leading to its current state, such as sedimentation rate and manganese encrusting.

We started to change our old (and unique!) citation style to adapt to the APA citation style (for information please see: https://www.mendeley.com/guides/apa-citation-guide) to make the usage of references listed in shark references easier and more compatible with a widely accepted reference style adopted by several international scientific journals. The transition is ongoing, so far 26476 (last month: 26252) references are changed.


Since we were asked several times, if we could help distributing chondrichthyan-related job opportunities, we would like to try this out as a new category in the newsletter besides postings on our Facebook page. This category definitely depends on the community sharing job openings, so please do not hesitate and send us vacancies or similar.
Right now, we have four interesting job openings. We will keep it simple and just crosslink:

Here, we focus on the elasmobranch fauna to determine the trophic relationships within the OMM, using fossil teeth as proxies for diet and trophic levels based on functional morphology and an actualistic species- or genus-level approach. Herein we present a fresh and comprehensive palaeoecological reconstruction of the OMM ecosystem in Baden-Württemberg. All five outcrop areas available for the present analysis (Baltringen, Meßkirch-Rengetsweiler, Meßkirch-Walbertsweiler, Ulm-Ermingen, and Ursendorf) exhibit a similar faunal composition, with the apex predator being Otodus (Megaselachus) sp. Among the other elasmobranchs, there are mostly piscivorous and malacophagous species; taxa that feed on a variety of other invertebrates or amniotes (including marine mammals) are also present. The OMM sediments deposited in shallow-water settings, but there are fossils of more oceanic species that might, at times, have approached the shore. With a soft bottom, partly covered by sea grass, the OMM environment would have been like the present-day warm-waters settings of the Mediterranean.

Gymnurid rays are found in tropical, subtropical, and temperate regions around the world, where they are associated with sandy or muddy bottoms in coastal areas, being easily distinguished from other rays by the width of the disc. In recent years, the systematics of this family have been revised extensively. However, there has been no comprehensive molecular review of the family based on an adequate sample of species and localities, which may have obscured the presence of distinct evolutionary lineages. The present study was based on samples of 12 of the 13 valid species of the genus Gymnura, which were used for a multilocus reconstruction of the evolutionary history of the family Gymnuridae. Our results indicate the existence of several cryptic gymnurid lineages, within the species Gymnura micrura, Gymnura lessae, Gymnura altavela, and Gymnura poecilura. Also, we indicate that only half of the species that compose the genus are known, as well their conservation status. The analyses also indicate that the gymnurids originated during the Paleocene, with events of dispersal and vicariance occurring through the formation of oceanographic barriers, and species diversification peaking during the Oligocene and Miocene. The results of the present study reinforce the need for a comprehensive revision of the systematics of the family, in particular, the widely distributed species that are considered valid taxa, but may, in fact, represent different cryptic species. The inadequate classification of this cryptic diversity may have negative implications for the development of effective conservation measures.

Last, P.R. & Weigmann, S. & Naylor, G.J.P. (2023)
The Indo-Pacific Stingray Genus Brevitrygon (Myliobatiformes: Dasyatidae): Clarification of Historical Names and Description of a New Species, B. manjajiae sp. nov., from the Western Indian Ocean. Diversity, 15(12), Article 1213
New species: Brevitrygon manjajiae
Abstract: Members of the genus Brevitrygon are small, locally abundant tropical stingrays (family Dasyatidae) occurring in soft sedimentary habitats of inner continental shelves of the Indo-West Pacific from the Red Sea to Indonesia. Formerly members of the genus Himantura, whose members lack dorsal and ventral skin folds on the tail (typical of most dasyatid genera), folds are present or rudimentary in some Brevitrygon. Important to artisanal fisheries and known to consist of at least five species, these fishes are possibly the most frequently misidentified of all stingrays. Most were inadequately described in the 19th century, and they are often taxonomically confused due to morphological similarity, ontogenetic variability, and sexual dimorphism. Their nomenclatural history is complex with four of the known species represented within the type series of one species, B. walga (Müller & Henle). Also, the type of the species with which B. walga is most often confused, B. imbricata (Bloch & Schneider) from off southern India and Sri Lanka, is in very poor condition. A lectotype has been designated for B. walga (confined to the Bay of Bengal). The genus also contains B. heterura (Bleeker) from the Indo-Malay Archipelago, B. javaensis (Last & White) from off southern Indonesia, and a new species, B. manjajiae sp. nov., from the western Indian Ocean. The former species are redescribed and redefined based largely on a combination of morphometrics, tail morphology, squamation, and molecular data. Molecular divergences were detected within lineages of B. heteruraB. walga and B. manjajiae sp. nov., requiring further investigation.

Boulemia, S. & Adnet, S. (2023) A new Palaeogene elasmobranch fauna (Tebessa region, eastern Algeria) and the importance of Algerian-Tunisian phosphates for the North African fossil record. Annales de Paléontologie, 109(3), Article 102632
New species: Physogaleus onkensis
Abstract: During the Palaeocene-Eocene transition, the southern Tethys margin is characterized by several African phosphate deposits with many fossil teeth of elasmobranchs. Contrary to the rich Moroccan fossil record, fossil elasmobranchs from the area that includes today the Algerian-Tunisian border (e.g. Metlaoui-Gafsa-Onk Basin) have received few attentation since the last century of exploration. New collecting in the vicinity of Tebessa, Eastern Algeria (Jebel El Onk mine) allowed to report a new elasmobranch fauna in the so-called “Upper Thanetian” level. It consists of 28 taxa including a new species of a galeocerdid, Physogaleus onkensis sp. nov., which is characterized by a possible crushing adaptability of their teeth. The majority of the reported species are known in coeval phosphate levels enabling preliminary conclusions about the depositional time and correlations to the related faunas of the region. The faunal from the Jebel El Onk mine is considered as late Thanetian–early Ypresian in age.

Palm, H.W. & Haseli, M. (2023) Tentaculariids (Cestoda, Trypanorhyncha) of elasmobranchs from Malaysian Borneo. Zoosystema, 45(18), 513–529
New species: Homeokotorella anterioporus, Nybelinia pseudafricana
Abstract: The waters off Borneo, the third-largest island in the world located at the geographic centre of Maritime Southeast Asia, harbour a high diversity of marine cestodes. We examined the tentaculariid species collection of the large-scale sampling endeavours in Malaysian Borneo between 2002 and 2008. Our study resulted in reporting the tentaculariid fauna of the region with greater detail, describing two new species, and erecting a new genus, Nybelinia pseudafricana n. sp. and Homeokotorella anterioporus n. gen., n. sp. A comparison of N. sphyrnae Yamaguti, 1952 from Malaysian Borneo, Australia, New Caledonia, and Japan revealed the synonymy of N. jayapaulazariahi Reimer, 1980 with N. sphyrnae. Remarks are provided for NsphyrnaeNaequidentata (Shipley & Hornell, 1906Dollfus, 1930Heteronybelinia estigmena (Dollfus, 1960Palm, 1999Tentacularia coryphaenae Bosc, 1802, Kotorella pronosoma (Stossich, 1900) Euzet & Radujkovic, 1989, and Kotorelliella (abbr. Ko.jonesi Palm & Beveridge, 2002 and new host records are established for Naequidentata and Ko. jonesiNybelinia aequidentata is reported for the first time from this region. Since most of the trypanorhynch species, including the tentaculariids, reported so far off Borneo are the same as those recorded off Indonesia, it seems that the trypanorhynch fauna of Borneo resembles the one from the Indonesian waters including to date 21 species (36%) of a total of 58 known tentaculariid species and 86 species (26%) of a total of 335 valid trypanorhynch species. These results allow us to better understand the species diversity of the tentaculariid trypanorhynchs off Malaysian Borneo.

Beyond Jaws

New episode of the podcast Beyond Jaws!

In this episode of the Beyond Jaws podcast, we talk to Jaelyn Myers, a PhD student from Australia who started her graduate work during the COVID-19 pandemic. She shares the challenges she faced and discusses her science communication work with Stingrays. We also delve into the reasons behind her science communication efforts, her Instagram account, and the progress of her PhD.


Both Beyond Jaws audio and video shows can be followed and subscribed. Beyond Jaws is supported by the Save Our Seas Foundation.


Evolution of taste: Early sharks were able to perceive bitter substances

Date: November 13, 2023
Source: University of Cologne
Summary: New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.

Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks

Date: November 7, 2023
Source: Trinity College Dublin
Summary: Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the 'Meg'), they think their work suggests there are more warm-blooded sharks out there than previously believed, and -- based on the Meg's demise -- these species may be at great risk from warming seas.
