Our new paper from the team shark-references is out  Thanks to Iris Feichtinger and Kent Albin Nielsen for this great team work!    Jürgen Pollerspöck, Kent Albin Nielsen, Iris Feichtinger & Nicolas Straube 2023. New records of fossil deep-sea shark teeth from the Lillebælt Clay (Early–Middle Eocene) of Denmark. Bulletin of the Geological Society of Denmark, Vol. 72, 153–173. ISSN 2245-7070. https://doi.org/10.37570/bgsd-2022-72-06 free download via researchgate https://www.researchgate.net/.../373098746_New_records_of... This study describes for the first time a number of distinct fossil teeth documenting several deep-sea shark species from the Eocene, which were previously not recorded from the North Sea Basin, including Apristurus sp., Orthechinorhinus cf. pfeili, Deania cf. angoumeensis, Squaliolus sp., Etmopterus cf. cahuzaci and Paraetmopterus nolfi. Our findings significantly increase the deep-sea shark diversity documented from this area so far. Despite the fact that the North Sea Basin had already lost direct connections to the neighbouring marine areas in the Eocene, the fauna shows highest similarities with documented Eocene deep-sea faunas of France, Austria and northern Morocco using cluster analysis.
------------------------------------------------------------------------------------------------------------------------ ADJUSTMENT OF CITATION STYLE IN SHARK REFERENCES 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 26071 (last month: 258677) references are changed. ------------------------------------------------------------------------------------------------------------------------ |

This article addresses the history of a resident population of bull sharks (Carcharhinus leucas) in an isolated stagnant body of water in subtropical Australia. From 1996 to 2013, six bull sharks were landlocked in a golf course lake near Brisbane. The adjacent Logan and Albert rivers trapped sharks due to major floodings. When floodwaters receded, these sharks remained in the lake, which is normally isolated from the riverʼs main channel. While this event was extensively reported in the media and recieved much public attention, it has not been investigated in depth, yet it provides an opportunity for insights into the tolerance of bull sharks to low salinity habitats and euryhalinity in this species. Currently, information on the extent of the bull sharkʼs capability to endure low salinity conditions and its longevity in these environments is scarce. The case reported here provides information on the occurrence of bull sharks for 17 years, which represents the longest uninterrupted duration in a low salinity environment that ever has been recorded in this species. Bull sharks arrived first in the lake as juveniles but through time, they have reached maturity. This occurrence presents not just another ordinary bull shark record from a low salinity environment but instead a record of physiological and scientific importance.

This is the first simultaneous morphological and barcoding characterization with the cytochrome c oxidase subunit I (COI) of the bramble shark Echinorhinus from the coast of Oman. The morphology of the specimen was consistent with previous records of Echinorhinus from the Gulf of Oman and the Arabian Sea (Northwestern Indian Ocean). However, the new COI haplotype clustered together with homologous sequences of specimens from India. The specimen from Oman distinguished morphologically and genetically from an E. brucus from the Western Atlantic Ocean on the shape and size of the dermal denticles, the proportions of twelve morphometric measurements (differences ⩾3%) and the genetic p-distance = 3.8% of the COI fragment. The haplotype reported here increases the genetic diversity in genus Echinorhinus in the Northwest Indian Ocean, demonstrates conspecificity between specimens from Oman and Echinorhinus cf. E. brucus distributed in India and extends its range of distribution. The limited morphological and molecular data available constrained assigning our specimen to other than Echinorhinus cf. E. brucus (Bonnaterrez, 1788). Our findings highlight the urgent need of morphological review, redescription and the assignment of a neotype in order to guarantee accurate species identification and thus effective conservation measures for these deep-sea sharks. The existence of a third living species in the genus is briefly discussed.

Upcoming Meetings:
----------------------------------------------------------------------------------------------------------------------
Welcome
We look forward to welcoming you to the University of Auckland, located in the heart of Auckland city. We invite you to come and meet the people that live and work here, explore our beautiful city and hope that you leave with lasting friends, partnerships and memories.
The Organising Committee look forward to welcoming you to the 11th Indo-Pacific Fish Conference (IPFC) and Annual Conference of the Australian Society for Fish Biology, to be held 20-24 November 2023 at the University of Auckland, New Zealand.
The Indo-Pacific Fish Conference (IPFC), held every four years, is undoubtedly one of the world’s premier ichthyological conferences and is eagerly anticipated by marine, estuarine and freshwater fish enthusiasts alike.
The Australian Society for Fish Biology (ASFB), founded in 1971, aims to promote research, education and management of fish and fisheries across the Indo-Pacific.
We are excited to bring these two conference together in a joint meeting that will reflect the extraordinary biological, environmental and cultural diversity of the vast Indo-Pacific region.
Auckland is a modern city offering a variety of cultural experiences, accommodation and entertainment options for every taste and budget. The city is a key regional hub, with transport connections to multiple cities across New Zealand, Australia, the Pacific and beyond.
The University of Auckland is an internationally recognised university that provides outstanding conference facilities and conference support within easy walking distance of the city centre. An exciting programme of conference field trips will allow attendees to sample the diversity of regional marine and freshwater ecosystems. Before or after the conference, delegates could explore Auckland’s magnificent Hauraki Gulf and its beautiful islands. The jewel of the gulf is Waiheke Island, a haven of vineyards, olive groves, beaches and fine dining, just a 40-minute ferry ride from downtown Auckland. For an exciting day trip, discover the history and sandy coves of Rotoroa Island, explore the open wildlife sanctuary of Tiritiri Matangi Island or climb the volcanic cone of Rangitoto Island for incredible views from the summit. If you have a little more time, travel south for a summer holiday to discover the majestic Milford and Doubtful Sounds, encounter marine life in Abel Tasman National Park, enjoy New Zealand’s beautiful Bay of Islands, or maybe plan a field trip or tropical holiday on one of the many Pacific islands that are only a short flight away from Auckland.
We look forward to welcoming you to Auckland in 2023!

94th Annual Meeting of the Palaeontological Society (PalGes) in Jena, 18.-22.9.2023
From Early Life to the Neandertals
For the first time since founding of the Palaeontological Society (PalGes) in Greifswald 1912 the annual meeting takes place in Jena. This is only the second time in Thuringia since the 1925 meeting in Weimar. We, from the Institute of Geosciences (IGW) at the Friedrich Schiller University of Jena, are glad to invite the members of the Society to our city at the river Saale. The city is a special location, stretching along the river, which is carving into a Muschelkalk plateau with Buntsandstein outcropping below. The surrounding Muschelkalk heights provide marvellous sights over the city. Our institute is located on the slope of the Hausberg in the eastern part of Jena. It was re-founded 1992 and still grows with an increasing number of scientists. Jena houses the most important university of Thuringia and is also a flourishing economic centre with companies like ZEISS and SCHOTT, it is popular for its touristic sights and a wide range of restaurants. The Thuringian palaeontology has a long tradition and is famous for fossils from the Permian, Triassic and Quaternary. We can offer a diverse range of excursions covering fossil sites from the late Palaeozoic to the Quaternary. The organisation of the meeting is supported by colleagues from Thüringischer Geologischer Verein (TGV), Stiftung Schloss Friedenstein Gotha, Museum Schloss Bertholdsburg Schleusingen, Research Station of Quaternary Palaeontology Weimar, and Phyletical Museum Jena. We are looking forward to welcome you in Jena and hear your presentations at 94. Annual Meeting of the PalGes in Jena!

https://whitesharksglobal.com/
The organising committee is pleased to announce the upcoming White Sharks Global conference (Sunday 12th – Friday 17th of November 2023) in Port Lincoln, South Australia, home of the world’s first white shark tourism industry.
White Sharks Global is the first international white shark conference in 13 years and will provide a forum for the white shark community and stakeholders to meet, share ideas, and update information and report on recent scientific studies. This conference and associated workshops will facilitate in-depth discussions of key challenges related to white sharks.
For more information visit: whitesharksglobal.com and follow @WhiteSharksGlob or contact info@whitesharksglobal.com
The last white shark-focused conference was in Hawaii 13 years ago in early 2010 and a lot has research and studies have happened since.
We have planned for five days of conference, with one day free in the middle to allow for a dive trip to the Neptune Islands Group Marine Park. There will be several focused workshops (e.g., supporting the recovery of white shark populations, supporting the management of white shark tourism, managing human-shark conflict), contributed talk sessions (5- and 15-min talks), and poster sessions. Based on previous events and our survey, we are expecting ~150 attendants from across the globe, including research scientists, students, resource managers, public safety officials, wildlife tourism operators, environmental consultants, natural history-based production companies, and television network representatives from countries all over the world such as South Africa, United States, Australia, Mexico, New Zealand, and Canada.

TAXONOMIC NEWS/ NEW SPECIES
Extant Chondrichthyes:
Fricke, R. & Durville, P. & Potin, G. & Mulochau, T. (2023) Squalus longispinis, a new species of spurdog (Elasmobranchii: Squalidae) from La Réunion, southwestern Indian Ocean. Taxa, 2, Article ad23203
New species: Squalus longispinis
Abstract: A new species of spurdog, Squalus longispinis n. sp. from La Réunion, is described on the basis of a single specimen collected with a longline at 1,000 m depth; another specimen was observed, but not collected, in the same area, at 900 m depth. The new species is diagnosed by the following characters: snout short, preorbital length 8.2% of total length (TL), prenarial length in inner nostril-narial furrow space 0.86; body very high, abdomen height 16.4% of TL, head height in trunk height 0.5; dorsal fin beginning on a vertical above posterior lobes of pectoral fin; second dorsal fin positioned in the middle between anal fin and caudal fin; first and second dorsal-fin spines long, first dorsal-fin spine 5.8% of TL, second-dorsal fin spine 5.3% of TL; flank denticles tricuspid; monospondylous vertebrae 37, precaudal vertebrae 86, caudal vertebrae 26, total vertebrae 112; upper caudal-fin lobe broad; caudal fin distally with a narrow, light grey margin. The new species is compared with other species in the genus. A key to the species of Squalus of the Indian Ocean is presented.

Wen, W. & Zhang, Q.Y. & Kriwet, J. & Hu, S.X. & Zhou, C.Y. & Huang, J.Y. & Cui, X.D. & Min, X. & Benton, M.J. (2023) First occurrence of hybodontid teeth in the Luoping Biota (Middle Triassic, Anisian) and recovery of the marine ecosystem after the end-Permian mass extinction. Palaeogeography Palaeoclimatology Palaeoecology, 617, Article 111471
New genus: Luopingselache
New species: Luopingselache striata
Abstract: Hybodont sharks were some of the most successful chondrichthyan lineages of all time, first occurring in the Devonian and becoming extinct in the Late Cretaceous. The end-Permian mass extinction had a limited effect on hybodont sharks, but there are fewer records of hybodonts in the Triassic than in the Jurassic and Cretaceous in China. The Middle Triassic Luoping Biota (Pelsonian, Anisian) is famous as an example of complete re-establishment of a shallow marine food web after the end-Permian mass extinction. Actinopterygian fishes are abundant and diverse in this assemblage, with 31 taxa described, including Halecomorphi and Ginglymodi, but few chondrichthyan fishes. Here we describe three taxa of hybodontid sharks based on teeth for the first time, one of them ascribed to a new taxon of Lonchidiidae, Luopingselache striata gen. et sp. nov., and the other two to Acrodus. The dentition of Luopingselache striata is preserved in situ and shows pronounced monognathic heterodonty. This represents the first detailed account of hybodont dentition with information of tooth replacement rate from the Mesozoic of China. We show that the tooth replacement rate is very rapid, namely 2.6 days/row on average, which might be an adaptation to replace broken teeth and insure the maintenance of an adequate dentition. Further, the newly discovered crushing-type Luopingselache and the durophagous Acrodus sp. A and B not only made the food web more complex, but also emphasized the recovery of the marine ecosystem in the Middle Triassic after the end-Permian mass extinction.

New family: Dasyomyliobatidae
New genus: Dasyomyliobatis
New species: Dasyomyliobatis thomyorkei
Abstract: Studies of the origin of evolutionary novelties (novel traits, feeding modes, behaviours, ecological niches, etc.) have considered a number of taxa experimenting with new body plans, allowing them to occupy new habitats and exploit new trophic resources. In the marine realm, colonization of pelagic environments by marine fishes occurred recurrently through time. Stingrays (Myliobatiformes) are a diverse clade of batoid fishes commonly known to possess venomous tail stings. Current hypotheses suggest that stingrays experimented with a transition from a benthic to a pelagic/benthopelagic habitat coupled with a transition from a non-durophagous diet to extreme durophagy. However, there is no study detailing macroevolutionary patterns to understand how and when habitat shift and feeding specialization arose along their evolutionary history. A new exquisitely preserved fossil stingray from the Eocene Konservat-Lagerstätte of Bolca (Italy) exhibits a unique mosaic of plesiomorphic features of the rajobenthic ecomorph, and derived traits of aquilopelagic taxa, that helps to clarify the evolutionary origin of durophagy and pelagic lifestyle in stingrays. A scenario of early evolution of the aquilopelagic ecomorph is proposed based on new data, and the possible adaptive meaning of the observed evolutionary changes is discussed. The body plan of †Dasyomyliobatis thomyorkei gen. et sp. nov. is intermediate between the rajobenthic and more derived aquilopelagic stingrays, supporting its stem phylogenetic position and the hypothesis that the aquilopelagic body plan arose in association with the evolution of durophagy and pelagic lifestyle from a benthic, soft-prey feeder ancestor.

New genus: Strigilisodus
New species: Strigilisodus tollesonae
Abstract: Isolated teeth of two janassid petalodonts collected from cave passages within the Middle Mississippian (Viséan) Joppa Member of the Ste. Genevieve Formation at Mammoth Cave National Park, Kentucky represents the first record of this group of chondrichthyans from this formation. A new janassid, Strigilodus tollesonae, gen et sp. nov., is recognised from isolated teeth, representing all tooth families, and are characterised by their rounded spoonlike cusps and V- to U-shaped lingual cristae. Janassa sp. is also present within the Joppa Member of the Ste. Genevieve Formation. Dental reconstructions are proposed for Strigilodus tollesonae and Cypripediodens cristatus, modelled after previous observations for Janassa dentitions. Strigilodus had a dental arrangement more similar to Janassa, while Cypripediodens was uniquely adapted for a possible extreme form of durophage feeding. We propose that within Janassidae, there were two unnamed subfamilies with Janassa and Strigilodus forming the Janassinae, while Cholodus, Cypripediodens, and Cavusodus forming Cholodinae subfam. nov.
Parasites:
Mendez, O. (2023) Paronatrema guillerminae n. sp. (Digenea: Syncoeliidae) parasite of the blue shark Prionace glauca (Linnaeus) (Elasmobranchii: Carcharhinidae) off the western coast of Baja California Sur, Mexico. Revista Mexicana De Biodiversidad, 94, Article e944987
New species: Paronatrema guillerminae
Abstract: Nine specimens of Paronatrema guillerminae n. sp. were collected from the gills of the blue shark Prionace glauca (Linnaeus) captured by artisanal fishing in the locality of Punta Belcher (Magdalena Bay), Baja California Sur, Mexico. Paronatrema guillerminae n. sp. is proposed as a new species because it presents distinctive characteristics within the genus Paronatrema (Dollfus), in the following morphological traits: body size, (larger than congeneric species), tegument with scale-like extensions, ovary shape (rounded), and testes number (more than 200). The new species is described herein.
