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. ------------------------------ ------------------------------ ------------------------------ ------------------------------

Upcoming Meetings:
----------------------------------------------------------------------------------------------------------------------
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.
What’s new?
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!

II ELASMulheres Symposium
November 06 – 12, 2021
Brazil, virtual
https://doity.com.br/ii-elasmulheres
https://elasmulheres.weebly.com/
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 elasmulheres.simposio@gmail.com and we will be glad to guide you.
[Português]
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 elasmulheres.simposio@gmail.com e nós te ajudaremos.

TAXONOMIC NEWS/ NEW SPECIES
Extant Chondrichthyes:
no taxonomic news this month
Extinct Chondrichthyes:
Lebedev, O.A. & Popov, E.V. & Bagirov, S.V. & Bolshiyanov, I.P. & Kadyrov, R.I. & Statsenko, E.O. (2021): The earliest chimaeriform fish from the Carboniferous of Central Russia. Journal of Systematic Palaeontology, in press
New species: Protochimaera mirabilis
Abstract: The ancestry of chimaeriform chondrichthyan fishes can be traced back to the Late Triassic (∼220 Ma). To date, only one chimaeriform suborder, the Echinochimaeroidei, has been recognized from the Palaeozoic. The origin and evolution of the chimaeriforms has been a matter of debate for more than a hundred years. This problem is aggravated by the scarcity of holomorphic fossils; the bulk of the material includes only hard parts of the jaw apparatus and other skeletal elements. Here we describe the oldest record of the Chimaeriformes, represented by tooth plates from the lower Carboniferous deposits (∼338–332 Ma) of Russia, as Protochimaera mirabilis gen. et sp. nov., and establish a new family and suborder based upon their particular morphological and histological features. The newly described tooth plates demonstrate a continuous layer of varitubate dentine over their oral surfaces; beak-shaped mandibular plates have been formed by fusion of a labial component of cutaneous origin to two others formed orally. Three separate vascular systems enabled the growth of these histological components. The beak and wear facets suggest a grasping-cutting feeding action and are the earliest example of this feeding mode in fishes after the placoderm extinction at the end of the Devonian. Phylogenetic analysis of the dental characters places these stem chimaeriforms as a sister group to the Chimaeroidei.
Parasites:
Alama-Bermejo, G. & Šíma, R. & Raga, J.A. & Holzer, A.S. (2021): Myxidium tunisiensis n. sp. (Myxosporea: Myxidiidae) infecting the rough skate Raja radula Delaroche, 1908 (Rajiformes: Rajidae) from North East Tunisia. Parasitology Research, in press
New species: Myxidium tunisiensis
Abstract: A new marine myxosporean, Myxidium tunisiensis n. sp. (Myxosporea: Myxidiidae), is described infecting the gallbladder of the rough skate Raja radula Delaroche, 1908 (Chondrichthyes: Rajidae) harvested from the Bay of Bizerte, Tunisia. Observed stages of the parasite were floating free in the bile. Plasmodia, disporic or polysporic, contain disporic pansporoblasts measuring 23.0–27.2 μm in maximum diameter and 21.0–25.5 μm in minimum diameter. Mature myxospores, which are elongated, typically fusiform measured 18.6 ± 1.7 (17.2–22.0) μm in length, 8.6 ± 1.2 (7.2–11.2) μm in width and 8.2 ± 0.9 (6.4–10.1) in thickness. Myxospore valves are symmetrical with 9–10 longitudinal striations. Two polar capsules, pyriform, were equal in size, measuring 5.8 ± 0.4 (5.2–6.7) μm in length and 3.1 ± 0.2 (3.0–3.2) μm in width, with 5–6 polar filament turns. The infection was prevalent throughout the year with the highest prevalence in autumn (81.8%) and the lowest in winter (32.3%). The seasonal prevalence of M. tunisiensis n. sp. in the Bay of Bizerte appeared to fluctuate according to seawater temperature. The morphological and morphometrical differences with all Myxidium spp. described so far, complemented by molecular data, prove clearly that the present species is a new member of the genus Myxidium. The SSU rDNA phylogenetic analyses revealed that Myxidium tunisiensis n. sp. clustered within the oligochaete-gallbladder clade in a basal position to the marine subclade of Myxidium baueri and Myxidium coryphaenoideum. While the new species branching pattern is stable in the ML and the BI analyses, it changed in the MP analysis. This is the first molecular study of a Myxidium species infecting an elasmobranch host inhabiting the Mediterranean Sea.

In actie voor de bedreigde haaien en roggen
Stichting IFAW
23-OKT-2021 - Als bij een internationale bijeenkomst een dier officieel op de lijst van bedreigde diersoorten wordt gezet, haalt dat het nieuws en is iedereen blij. Want het tij is immers gekeerd en het dier wordt nu niet meer met uitsterven bedreigd. Toch?

Haaienmoeders baren in Zeeuwse zeearmen
ARK Natuurontwikkeling, Sportvisserij Nederland, Wageningen University & Research
24-OKT-2021 - Vrouwtjes van de gevlekte gladde haai zwemmen in de zomer naar de Ooster- en Westerschelde om daar – na een zwangerschap van maar liefst een jaar – hun jongen te baren. De Zeeuwse delta vervult daarmee een belangrijke rol voor deze soort, blijkt uit een onderzoek met vin-merkjes. In de winter zwemmen de zwangere haaiendames naar het zuiden, terwijl veel mannetjes naar het noorden trekken.
