The Mexican Society of Cartilaginous Fishes A.C., in coordination with the Planetarium of Playa del Carmen SAYAB, invites to participate in the First Latin American Conference of Sharks, Rays and Chimaeras, and the VIII National Symposium of Sharks and Rays.


5th International Whale Shark Conference (IWSC5) from 28-31 May 2019

From 28-31 May 2019, the town of Exmouth in the Ningaloo Coast World Heritage Area will welcome delegates to the 5thInternational Whale Shark Conference (IWSC5), a meeting of the world’s leading whale shark scientists, conservationists, natural resource managers and tourism managers. This is the fifth such conference to be held, following on from the successful IWSC4 held in Doha, Qatar in 2016. This meeting is timed to showcase Ningaloo’s world’s best practice whale shark management program and will follow the Ningaloo Whaleshark Festival, an annual community event that celebrates these magnificent animals.
IWSC5 will bring together local scientists, researchers and postgraduate students to interact with international colleagues and collaborators to explore all aspects of whale shark biology and ecology and how this can translate to direct, on-ground conservation efforts. Delegates from around the world will be treated to four days of presentations, workshops, social functions and experiencing the world renowned Ningaloo whale shark tourism industry to forge new relationships and collaborations and debate ideas.
A core focus of IWSC5 will be bringing together end users of the science being presented, such as tourism managers, marine park managers and conservation groups. This will improve the uptake and application of research and help develop collaborations between research scientists and managers and industry.

SAMONDS, K.E. & ANDRIANAVALONA, T.H. & WALLETT, L.A. & ZALMOUT, I.S. & WARD, D.J. (2019): A middle - late Eocene neoselachian assemblage from nearshore marine deposits, Mahajanga Basin, northwestern Madagascar. PLoS ONE, 14 (2): e0211789

New species: Carcharhinus underwoodi

Abstract: We report here the first neoselachian fossil fauna from Eocene nearshore marine deposits of the Mahajanga Basin, northwestern Madagascar. The fauna includes seven species of shark: Nebrius blankenhorniBrachycarcharias koertiGaleocerdo eaglesomei, two species of Carcharhinus (one of which is described as a new species), PhysogaleusRhizoprionodon and Sphyrna. Three species of rays were also recovered: PristisMyliobatis and an undetermined dasyatid ray. This fauna represents the first Cenozoic neoselachian fossil record from the Eocene of Madagascar and broadens our understanding of their evolutionary and biogeographic history in the southern hemisphere during this time. Although the diversity of the genera and species of the fauna is very low, the age and similarity of genera to those in Congo, west Africa, Arabia, Asia, Europe, and North, Central, and South America suggests that these genera were broadly distributed and diverse within the shallow marine settings of the Tethyan and southern provinces during middle and late Eocene.

 A new lamniform shark Protolamna ricaurtei sp. nov. from the Lower Cretaceous of Colombia. Cretaceous Research, 95: 336-340

New species: Protolamna ricaurtei

Abstract: The Lower Cretaceous record of lamniforms from South America is scarce and poorly known, containing only two reports of isolated teeth from the upper Hauterivian of Argentina and the Albian of Peru. Here, we describe a partial articulated tooth set referable to †Protolamna ricaurtei sp. nov. from the upper Barremian–lower Aptiandeposits of the Paja Formation (Andes of Colombia). The new species corresponds to one of the oldest fossil lamniforms to date reported from South America. This articulated tooth set is the only known for the family †Pseudoscapanorhynchidae, and possibly the oldest in its type for a lamniform from the Lower Cretaceous. Our findings offer new insights in to the lamniform paleodiversity of the northwestern margin of Gondwanaduring the Early Cretaceous.

RICHARDS, K.R. & SHERWIN, J.E. & SMITHSON, T.R. & BENNION, R.F. & DAVIES, S.J. & MARSHALL, J.E.A. & CLACK, J.A. (2018):Diverse and durophagous: Early Carboniferous chondrichthyans from the Scottish Borders. Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 108 (1): 67-87

New genus: Whitropus

New species: Whitropus longicalcus, Deltodus tubineus

Chondrichthyan teeth from a new locality in the Scottish Borders supply additional evidence of Early Carboniferous chondrichthyans in the UK. The interbedded dolostones and siltstones of the Ballagan Formation exposed along Whitrope Burn are interpreted as representing a restricted lagoonal environment that received significant amounts of land-derived sediment. This site is palynologically dated to the latest Tournaisian–early Viséan. The diverse dental fauna documented here is dominated by large crushing holocephalan toothplates, with very few, small non-crushing chondrichthyan teeth. Two new taxa are named and described. Our samples are consistent with worldwide evidence that chondrichthyan crushing faunas are common following the Hangenberg extinction event. The lagoonal habitat represented by Whitrope Burn may represent a temporary refugium that was host to a near-relict fauna dominated by large holocephalan chondrichthyans with crushing dentitions. Many of these had already become scarce in other localities by the Viséan and become extinct later in the Carboniferous. This fauna provides evidence of early endemism or niche separation within European chondrichthyan faunas at this time. This evidence points to a complex picture in which the diversity of durophagous chondrichthyans is controlled by narrow spatial shifts in niche availability over time.

Giant 'megalodon' shark extinct earlier than previously thought

Prehistoric beast not killed off by a supernova

February 13, 2019
University of Wisconsin Oshkosh
'Megalodon' -- a giant predatory shark that has inspired numerous documentaries, books and blockbuster movies -- likely went extinct at least one million years earlier than previously thought, according to new research. This is a substantial adjustment as it means that O. megalodon likely went extinct long before a suite of strange seals, walruses, sea cows, porpoises, dolphins and whales all disappeared sometime about 1-2.5 million years ago.

Great white shark genome decoded

Huge genome reveals sequence adaptations in key wound healing and genome stability genes tied to cancer protection

In a major scientific step to understand the biology of this iconic apex predator and sharks in general, the entire genome of the white shark has now been decoded in detail.

Risk remains low despite rise in global shark attacks

February 27, 2019
Louisiana State University
A new study shows that although the number of shark attacks has increased over time, the rate of attack is low and the risk of being attacked by a shark is highly variable across the globe.

A rare assemblage of sharks and rays from nearshore environments of Eocene Madagascar

This finding, including one new shark species, fills a gap in the known marine record of Madagascar

February 27, 2019
Eocene-aged sediments of Madagascar contain a previously unknown fauna of sharks and rays, according to a new study. This newly described fauna is the first report of sharks and rays of this age in Madagascar.
