Upcoming Meetings:

II Joint Congress on Evolutionary Biology – Montpellier 2018

ESEB is delighted to welcome you to the Second Joint Congress on Evolutionary Biology. Joint Congresses take place every six years and bring together four of the world's largest academic societies in the field of evolutionary biology: the European Society for Evolutionary Biology, the American Society of Naturalists, the Society for the Study of Evolution and the Society of Systematic Biologists. The first joint congress was in Ottawa, Canada in 2012. The current (i.e. second) will be held in Montpellier, France, on August 19-22 2018.


The website and registration details for the OCS 2018 meeting next February are now online at http://www.oceaniasharks.org.au/conference-2018
The 2018 conference is going to be a little different. It’s going to be at Moreton Bay Research Station which is where in the early 2000’s a group of students started their own chondrichthyan focused workshops and seminars to provide a supportive and inclusive forum for presenting shark and ray research. Those events were part of what became the OCS in 2005. In 2018, we’re returning to where some of those early meetings were held, and incidentally, to a beautiful location on the coast with opportunities to dive with manta rays and leopard sharks following the conference. Research station based meetings have a different feel to the normal city or campus based meetings, and Stradbroke Island really is a beautiful location.
Registration and abstract submission are via the online form. Upon registering you should receive a PayPal receipt email as well as an acknowledgement from the conference website. If you encounter any problems with online registration or abstract submission, please contact Jon Smart (Jonathan.Smart@sa.gov.au).   
The deadline for abstracts is January 22.


João Pessoa, 3-8 June, 2018
The Sharks International Conference is the first truly international event devoted to elasmobranchs, and its first two editions were held respectively in Cairns, Australia in 2010 and Durban, South Africa in 2014. The city of João Pessoa was chosen as the venue for this important event, which will also congregate members of the Brazilian Society for the Study of Elasmobranchs (SBEEL) and the American Elasmobranch Society (AES) in 2018.
João Pessoa, founded in August 5, 1585, is the capital of Paraíba state, northeastern Brazil. It is located in the easternmost portion of the Americas, where a cape named Ponta do Seixas enters the Atlantic Ocean. Its coastline extends for 24 kilometers, with nine beaches. The downtown area and neighbouring municipalities present many historical and tourist sites.
More information and an internet site of the event will soon be available. We hope to have many participants from all over the world.

Extinct Chondrichthyes:

FUCHS, I. & ENGELBRECHT, A. & LUKENEDER, A. & KRIWET, J. (2017): New Early Cretaceous sharks (Chondrichthyes, Elasmobranchii) from deep-water deposits of Austria. Cretaceous Research, in press
New genus: Altusmirus, Fornicatus, Similiteroscyllium
New species: Altusmirus triquetrus, Similiteroscyllium iniquus, Fornicatus austriacus
Abstract: Early Cretaceous elasmobranchs still are very insufficiently known despite all progress that has been accomplished in recent years. Here, a small elasmobranch assemblage is presented from the Valanginian of Austria that contributes significantly to a better understanding of early Cretaceous elasmobranch diversity. The new assemblage comprises two new carcharhiniform sharks, Altusmirus triquetrus gen. et sp. nov. and Fornicatus austriacus gen. et sp. nov., a new orectolobiform shark, Similiteroscyllium iniquus gen. et sp. nov., and a galeomorph shark tooth of uncertain affinities. The recent identification of Similiteroscyllium gen. nov. has shown that it has strong similarities with Ornatoscyllium rugasimulatum from the Lower Cretaceous of France. Significant differences of the tooth morphology of O. rugasimulatum and the type specimen O. freemanijustify full reconsideration of the systematic position of O. rugasimulatum and require it to be reassigned to Similiteroscylliumgen. nov. described in this paper. The new assemblage described here, and those from the Valanginian of France and Poland comprising 30 additional taxa, indicates that Early Cretaceous elasmobranch diversity was significantly higher than previously assumed. Consequently, the supposed diversity decline of elasmobranchs across the Jurassic-Cretaceous boundary represents a collecting bias rather than a real pattern.

EBERSOLE, J.A. & EHRET, D.J. (2018):
 A new species of Cretalamna sensu stricto (Lamniformes, Otodontidae) from the Late Cretaceous (Santonian-Campanian) of Alabama, USA. PeerJ, 6: e4229
New species: Cretalamna bryanti
Abstract: Decades of collecting from exposures of the Upper Cretaceous Tombigbee Sand Member of the Eutaw Formation and Mooreville Chalk in Alabama, USA has produced large numbers of isolated Cretalamna (sensu stricto) teeth. Many of these teeth had formerly been assigned to the extinct Late Cretaceous shark Cretalamna appendiculata (Agassiz, 1843), a taxon that is now considered largely restricted to the Turonian of Europe. Recent studies have shed light on the diversity of Late Cretaceous Cretalamna (s.s.) taxa, and here we recognize a new species from Alabama, Cretalamna bryanti. The teeth of C. bryanti sp. nov. appear aligned with the members of the Cretalamna borealis species group, but can be distinguished from these other species by a combination of the following: anterior teeth with a more pronounced and triangular lingual root protuberance, broader triangular cusp, and a taller root relative to the height of the crown; anteriorly situated lateroposterior teeth have a distally inclined or hooked main cusp and more than one pair of lateral cusplets; and lateroposterior teeth have a strong distally hooked main cusp and a root that is largely symmetrical in basal view. At present, C. bryanti sp. nov. is stratigraphically confined to the Santonian/Campanian Dicarinella asymetrica Sigal, 1952 and Globotruncanita elevata Brotzen, 1934 Planktonic Foraminiferal Zones within the Tombigbee Sand Member of the Eutaw Formation and Mooreville Chalk, and teeth have been collected from only four counties in central and western Alabama. The recognition of C. bryanti sp. nov. in Alabama adds to our knowledge on the diversity and distribution of Late Cretaceous otodontids in the region.
PAULIV, V.E. & MARTINELLI, A.G. & FRANCISCHINI, H. & DENTZIEN-DIAS, P. & SOARES, M.B. & SCHULTZ, C.L. & RIBEIRO, A.M. (2017): The first Western Gondwanan species of Triodus Jordan 1849: A new Xenacanthiformes (Chondrichthyes) from the late Paleozoic of Southern Brazil. Journal of South American Earth Sciences, 80: 482-493
New species: Triodus richterae
AbstractTriodus is a well-known genus of Xenacanthiformes, previously recorded from the late Bashkirian (Lower Pennsylvanian, Carboniferous) to the middle Artinskian (Cisuralian, Permian), mainly from Laurasian deposits (Europe and USA). For the first time, this genus is recorded from the Western Gondwana, based on isolated teeth that are referred to Triodus richterae sp. nov. The new species were found associated with other shark teeth (another xenacanthiforms and a possible euselachian), palaeoniscoid teeth and scales, labyrinthodont teeth, tetrapod bony remains, macroscopic charcoal and leaf fragments. This fossil assemblage was collected in a conglomerate layer from the Barro Alto site (São Gabriel municipality, Rio Grande do Sul State, Brazil), with an estimated Capitanian age, from the Morro Pelado Member, Rio do Rasto Formation, Paraná Basin. The new species has teeth with an almost oval base and the aboral surface has a smooth concavity and a rounded to horseshoe-shaped basal tubercle. The coronal surface of these teeth has a tricuspid crown, a rhomboid-shaped coronal button with rounded edges with a lingually directed shaft and some oral foramina predominantly situated at the lingual margin of the base and flanking the lingual shaft. The lateral cusps bear a variable number of non-branching vertical cristae, distributed from the apex to their proximal portion, making the transversal section of these cusps asterisk-shaped. Microstructurally, these teeth have both base and cusps composed of orthodentine with an opened pulp cavity. T. richterae sp. nov. represents the youngest species of Triodus, considering it comes from Capitanian (late Guadalupian) beds, which are at least 15 Ma younger than T. kraetschmeri, the previously youngest species of this genus. The depositional interpretation, as well as the fossil assemblage in the type locality of the new species and of the Rio do Rasto Formation as a whole, indicates another freshwater record for xenacanthid sharks.


DIPPENAAR, S.M. (2017): Description of four new species and a revision of the genus Tripaphylus Richiardi in Anonymous, 1878 (Copepoda: Siphonostomatoida: Sphyriidae). Systematic Parasitology, in press
New species: Tripaphylus lewisi,Tripaphylus benzi, Tripaphylus hoi, Tripaphylus beatricae
Abstract: Tripaphylus Richiardi in Anonymous, 1878 is one of the genera of the Sphyriidae Wilson, 1919 and it currently accommodates ten species. Only scanty descriptions are available for the females and some males of the species. Tripaphylus specimens, described and illustrated in this paper, were collected from elasmobranch hosts off the South African coast or came from the private collection of the late Dr G. Benz. Collected specimens were fixed and preserved in 70% ethanol, examined by light - and scanning electron microscopy, and compared with the known species. Descriptions and illustrations are provided for the transformed adult females and males of Telongatus (Wilson, 1932) and Tversicolor (Wilson, 1919) while illustrated descriptions of the transformed adult females are also provided for Tferox (Wilson, 1919) and Tvaissierei (Delamare Deboutteville & Nuñes-Ruivo, 1954). Additionally, the material previously reported as Tferox is considered to represent Telongatus and that reported as Tlobatus (Kirtisinghe, 1964) is considered a junior synonym of Tvaissierei. Based on the collected material the transformed adult female and male of Tlewisi n. sp. are described as well as the adult transformed females of Tbenzi n. sp., Thoi n. sp., and Tbeatricae n. sp. A summarised review of the main features is provided for each of the previously described Tmusteli (van Beneden, 1851), Themigalei Kirtisinghe, 1964, Taustralis (Kabata, 1993), Ttriakis (Castro Romero, 2001) and Tasymboli (Turner, Kyne & Bennett, 2003). Furthermore, reasons are provided for the recommendation that Themigalei be considered a species inquirenda. An identification key to the transformed adult females of all species of Tripaphylus is provided and the host records are also updated.
