Abstract: The North Alpine Foreland Basin (NAFB) comprises one of the most complete sedimentary records of the Oligocene and Miocene. Driven by global sea-level fluctuations, vast sedimentary influx and tectonic movement. The locality of Unterrudling near Eferding (Upper Austria) exposes the largest succession of sedimentary deposits from the late Oligocene in the eastern NAFB. Additionally, this section shows the facies transition from the shallow-water Linz-Melk Formation to the deep-water Eferding Formation. In this work, the fossil fauna and flora of the Eferding Formation as well as its lithology are re-evaluated using a multidisciplinary approach to gain new insights into the palaeoenvironment, palaeoclimate, and palaeoecology. A transgressive sequence is documented using sedimentological and ichnological data. Furthermore, a correlation to the late Chattian transgressive Ch-3 sequence is suggested. The impact of rising sea level on marine biota is shown in detail by analysing various groups (Bivalvia, Echinodermata, Anthozoa, Foraminifera, Chondrichthyes, Osteichthyes), with several newly reported species from the Eferding Formation. Moreover, washed in plant material was analysed for the interpretation of the terrestrial climate indicating mainly humid subtropical conditions. Finally, the presence of phosphatic nodules indicates eutrophication on the shelf environment and the possibility of upwelling currents.
New publication on the taxonomy and distribution of the Smooth Lantern Shark Etmopterus pusillus
-OPEN ACCESS-Nicolas Straube
, Michaela Preick, Gavin J. P. Naylor and Michael Hofreiter
Mitochondrial DNA sequencing of a wet-collection syntype demonstrates the importance of type material as genetic resource for lantern shark taxonomy (Chondrichthyes: Etmopteridae). Royal Society Open Science, 8(9), Article 210474
Abstract: After initial detection of target archival DNA of a 116-year-old syntype specimen of the smooth lantern shark, Etmopterus pusillus
, in a single-stranded DNA library, we shotgun- sequenced additional 9 million reads from this same DNA library. Sequencing reads were used for extracting mitochondrial sequence information for analyses of mitochondrial DNA characteristics and reconstruction of the mitochondrial genome. The archival DNA is highly fragmented. A total of 4599 mitochondrial reads were available for the genome reconstruction using an iterative mapping approach.
The resulting genome sequence has 12 times coverage and a length of 16 741 bp. All 37 vertebrate mitochondrial loci plus the control region were identified and annotated. The mitochondrial NADH2 gene was subsequently used to place the syntype haplotype in a network comprising multiple E. pusillus
samples from various distant localities as well as
sequences from a morphological similar species, the shortfin smooth lantern shark Etmopterus joungi
. Results confirm the almost global distribution of E. pusillus
and suggest E. joungi
to be a junior synonym of E. pusillus
. As mitochondrial DNA often represents the only available reference information in non-model organisms, this study illustrates the importance of mitochondrial DNA from an aged, wet collection type specimen for taxonomy.https://royalsocietypublishing.org/doi/10.1098/rsos.210474
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 13800 references are changed.

The 24th Annual Scientific Meeting of the European Elasmobranch Association is planned to be held by the Dutch member group Nederlandse Elasmobranchen Vereniging (NEV) in Leiden, the Netherlands between 3rd and 5th November, 2021.
NEV, in consultation with the EEA Board, has decided to tentatively organise this year’s EEA Meeting as an in-person meeting. Luckily, NEV was able of having secured the same prime venue at the fascinating Naturalis Biodiversity Center! Leiden is a beautiful old university town just 20 mins from Schiphol airport and international train station.
Prior to the main meeting we will organise an online session on November 2nd to allow those who cannot attend in person to contribute.
We understand that there is still a lot of uncertainty as far as travel etc. is concerned. In mid-July we will make the decision whether or not to host a live event.
If an in-person meeting is not possible the entire EEA2021 will be online.
In the coming weeks the website for early registration will be updated, as well as opening the abstract submission for either an online or live presentation.
Details can be found on the NEV website: https://www.elasmobranch.nl/eea2021/
On September 15-18, 2019, Bettina Reichenbacher (Munich), Tomas Přikryl (Praha) and Gloria Arratia (Kansas) invited a first "Fossil Fish symposium In", in Munich, in the frame of the Paleontological Society of Germany.
We concluded the symposium deciding to stay as an informal community of "Fish Paleontologists that have something to do with Europe" and to meet again in the next years at the favor of other national Fish or Pal events.
The Société Française d'Ichtyologie organises the Rencontres de l'Ichtyologie en France every 3 years and will be pleased to host the next Fossil Fish symposium In in Paris, March 15-18, 2022.
The increasing use of virtual platforms to communicate science encouraged us to create the 1st Palaeontological Virtual Congress in December 2018, followed by the second edition in May 2020. The two firsts editions were a success, so we are glad to present the third edition of the Palaeontological Virtual Congress. Our purpose is to spread, worldwide, the most recent scientific advances in palaeontology in a fast, easy and economical way.
Our initiative was pioneering in palaeontology, being the first exclusively virtually developed conference in our field. In these challenging times, online platforms have gained great relevance and are key to keep up the drive for science communication among peers and enthusiasts. This year we didn’t want to miss the opportunity of offering you this platform so you can share your amazing research with the world, either by oral communications or slides presentations.
Even when online meetings are the norm, our main aim is still the same: to give international projection to the palaeontological research carried out by groups with limited economic resources, as well as to promote the participation of palaeontologists from developing countries around the world. And this is reflected in our low-cost registration fees.
In order to reach out as widely as possible to researchers with fewer resources, this year we have created a social fund for participants from low and lower-middle income countries listed as such on The World Bank’s list. Additionally, to increase the range and diversity of nationalities and areas of expertise, this year we are introducing the figure of ambassadors, for those participants who wish to advertise us among their colleagues in their country and/or speciality.
We have also set up a Discord server with multiple text and voice channels so you can give and receive feedback to and from your peers. We all miss seeing each other as we used to in conventional meetings, here you will be able to develop your networking skills and talk to other people face to face even if it’s through a screen. We know that some of us might have developed a bit of ‘zoom fatigue’, but we believe that participants will enjoy engaging in fruitful conversations, a taste of what scientific meetings used to be.
To sum up…
The 3rd Palaeontological Virtual Congress combines the benefits of traditional meetings (i.e., providing a forum for discussion, including guest lectures, and the production of an abstract book, among other features) with the advantages of online platforms, which allow a wider reach around the world. We would love to have you here sharing your research, engaging in exciting discussions, and enjoying other peers’ works.
More information coming soon, stay tuned!
6th Southern African Shark & Ray Symposium (SASRS)
November 17 – 19, 2021Gansbaai, South Africa
The Southern African Shark and Ray Symposium is a bienni-al meeting of the academic community of Southern Africa who are currently conducting research on these taxa.The SASRS will be composed of a combination of oral and poster presentations, work-shops, and public events – with plenty of added fun and adventure planned for attendees. Keynote presentations will be scheduled throughout the Symposium.
II ELASMulheres Symposium
November 06 – 12, 2021
This is an annual event organized by Brazilian women that research distinct aspects of elasmobranchs. Its name, in Portuguese, means: “ELAS” (THEY, female) and “Mulheres” (Women), besides playing with the word “ELASM”obranchs.
The goal of ELASMulheres is to contribute to our knowledge on elasmobranchs through talks and discussions provided by female scientists. The symposium also encompasses the scientific communication of studies developed by young women to empower this minority group working with sharks and rays.
Men are welcome to watch and present at II ELASMulheres, even though main talks will be given by Brazilian women scientists.
Since the symposium aims to promote equality, it will be presented in Portuguese. If you are not in Brazil and want to participate, please contact the organizing committee at email@example.com and we will be glad to guide you.
II Simpósio ELASMulheres
06 – 12 de Novembro de 2021
ELASMulheres é um evento anual organizado por elasmólogas brasileiras que estudam diversos aspectos desses animais incríveis: os elasmobrânquios (tubarões e raias)!
O objetivo deste simpósio é contribuir com o conhecimento de elasmobrânquios através de palestras e mesas-redondas ofertadas por mulheres cientistas, as quais estudam diferentes aspectos deste grupo taxonômico. Ademais, o evento propõe a divulgação científica de temas correlatos aos estudos destas pesquisadoras de forma a empoderar as jovens mulheres, consideradas grupo minorizado, trabalhando com o tema.
Homens são bem-vindos a assistir e a apresentar no II ELASMulheres, mas as apresentações nas mesas-redondas serão feitas por pesquisadoras mulheres brasileiras.
Como o simpósio almeja a igualdade, será apresentado em português. Se você não estiver no Brasil e quiser participar, por favor entre em contato com a comissão organizadora através do endereço de e-mail firstname.lastname@example.org e nós te ajudaremos.

Sharma, A. & Singh, S. (2021): A small assemblage of marine hybodont sharks from the Bathonian of the Jaisalmer Basin, India. Neues Jahrbuch für Geologie und Paläontologie, Abhandlungen, 301(3), 317–333
New species: Strophodus indicus
Abstract: We are describing a small assemblage of marine hybodont sharks from the Middle Jurassic (Bathonian) carbonate rocks of the Jaisalmer Basin, North-western India. The assemblage is represented by both cuspidate and crushing dental remains of the genus Planohybodus and Strophodus (previously Asteracanthus), respectively. This is the first record of Planohybodus sp., Strophodus magnus, Strophodus medius and Strophodus indicus sp. nov. from the Jurassic of India or any other Gondwanan continent. This is the most diverse Jurassic marine chondrichthyan faunal record from the Jaisalmer Basin to date. This chondrichthyan faunal record from the Bathonian of India has close affinity to the European forms. This study reveals a much wider paleogeographic distribution of hybodont sharks and corroborates their cosmopolitan presence in the Mesozoic seas. The discovery of a new species, Strophodus indicus sp. nov. from India demonstrates a greater diversity in the genus Strophodus.

New genus: Rosaodus, Favusodus, Keichouodus
New species: Rosaodus xingyiensis, Favusodus orientalis, Keichouodus nimaiguensis
Abstract: A detailed taxonomic study of a diverse chondrichthyan fauna from the Ladinian–Carnian (Middle–Late Triassic) interval at Nimaigu locality in Guizhou Province, South China is presented. Six taxa are described, two of which are assigned to Elasmobranchii incertae sedis (aff. Rosaodus sp., Rosaodus xingyiensis gen. et sp. nov.) and three to the Euselachii (Euselachii gen. et sp. indet., Favusodus orientalis gen. et sp. nov., Keichouodus nimaiguensis gen. et sp. nov.), while the last one represents a possible Holocephali (aff. Arctacanthus sp.). Their stratigraphic distribution is documented on a bed-by-bed basis. This fauna is unusual because it is dominated by sharks with a cladodont-like dentition (which were barely known after the end-Permian mass extinction), and because it is almost devoid of durophagous euselachians, which makes it different from all other contemporaneous shark faunas worldwide. Transitional features are documented between ‘cladodont’ teeth and those of neoselachian sharks, which provide new insights into the replacement pattern of ancient sharks by modern ones.

New species: Stillabothrium borneoense
Abstract: Examination of spiral intestines from Himantura tutul Borsa, Durand, Shen, Arlyza, Solihin, and Berrebi, 2013 (=Himantura uarnak 3 sensu Naylor et al. ), collected from Malaysian Borneo revealed the presence of a new species of tapeworm belonging to the genus Stillabothrium (Rhinebothriidea: Escherbothriidae). Stillabothrium borneoense n. sp. Herzog, Meininger, and Reyda is assigned to the genus based on its possession of a scolex with 4 bothridia divided into a distinct anterior region with facial loculi that are oriented horizontally and a distinct posterior region with facial loculi that are oriented vertically. The new species is distinguished from its congeners by features of the scolex and proglottids, including a vagina that recurves well anterior to the cirrus sac, as well as a unique locular arrangement not previously reported for members of this genus: 4 horizontally oriented loculi in the anterior region of the bothridia and 7 vertically oriented loculi in the posterior region of the bothridia. Stillabothrium borneoense n. sp. expands both known morphological variation and known host associations within the genus

The role of diet in the rise of modern shark communities
- Date: October 6, 2021
- Source: Uppsala University
- Summary: The availability of prey and the ability to adapt to changing environments played key roles in the evolution of sharks. A new study, in which over 3,000 shark teeth were analyzed, provides new insight into how modern shark communities were established.
Some shark species are tougher than others when it comes to surviving catch and release, study finds
- Date: September 15, 2021
- Source: New England Aquarium
- Summary: A new landmark study of over 300 sharks found that some species are extremely resilient to the stress of being caught and released in commercial longline fisheries while other species are much more likely to die.
