Upcoming Meetings:

11th International Cretaceous Symposium Warsaw, Poland, 2022

August 22-26

37th Annual Scientific Meeting American Elasmobranch Society (AES)
July 27 – 31, 2022 (Dates subject to change)
Spokane, WA, USA
elasmo.org asih.org/meetings
The American Elasmobranch Society is a non-profit organization that seeks to advance the scientific study of living and fossil sharks, skates, rays, and chimaeras, and the promotion of education, conservation, and wise utilization of natural resources. The Society holds annual meetings and presents research reports of interest to professionals and students of elasmobranch biology. Those meetings are held in conjunction with annual meetings of the American Society of Ichthyologists and Herpetologists each year at rotating North American venues.

5th International Marine ProtectedAreas Congress (IMPAC5)
September 1 – 8, 2022 Vancouver, Canada
impac5.ca
International Marine Protected Areas Congresses (IMPAC) are an opportunity for the global community of marine conservation managers and practitioners to exchange knowledge, experience and best practices to strengthen the conservation of marine biodiversity and to protect the natural and cultural heritage of the ocean. IMPAC5 will be jointly hosted by the Host First Nations — Musqueam Indian Band, Squamish Nation, and Tsleil-waututh Nation — together with the Province of British Columbia, the Government of Canada, the Canadian Parks and Wilderness Society (CPAWS) and the International Union for the Conservation of Nature (IUCN). IMPAC5 is an opportunity to bring together Indigenous peoples and cultures from around the world to embrace a collaborative approach and learn from Indigenous leadership in ocean conservation. Join thousands of marine protected area professionals from around the world to chart a course towards protecting 30% of the ocean by 2030. Learn about traditional marine protection practices and innovative sustainability initiatives from local and international indigenous experts.

Sharks International Conference 2022 (SI2022)
October 10 – 14, 2022 (online virtual conference)
October 20 – 22, 2022 (physical in-person conference)
Valencia, Spain
si2022.org
SI2022 is a hybrid event in October 2022 that will bring together a strong community of people from across the world interested in sharks and rays, all in the name of addressing the challenge of elasmobranch conservation in this Decade of Ocean Science. In association with the European Elasmobranch Association (EEA) and hosted by the Shark Trust, Submon, and Lamna, the event will include five online days (October 10- 14th) featuring enhanced digital content on key themes in shark conservation, leading up to a three-day physical conference in Valencia (October 20th-22nd). The conference is funded by the Save our Seas Foundation and will be based out of L’Oceanogràfic, the largest aquarium in Europe, and streamed live across the world. If you are interested in sharks and rays and want to be a part of the 300+ member community currently shaping SI2022, sign up to the portal at si2022.org. Join this year to be automatically entitled to a 10% discount when tickets become available.

Extinct Chondrichthyes:
Carrillo-Briceño, J.D. & Cadena, E. (2022): A new hybodontiform shark (Strophodus Agassiz 1838) from the Lower Cretaceous (Valanginian-Hauterivian) of Colombia. PeerJ, 10, Article e13496
New species: Strophodus rebecae
Abstract: The vertebrate marine faunas that inhabited northern South America during the Cretaceous are still poorly known. This study is a contribution to a growing wave of new studies on Lower Cretaceous vertebrates from Colombia. Here we report and describe a new species of a hybodontiform shark of the genus Strophodus, which we named Strophodus rebecae sp. nov., based on isolated teeth, that were collected in Valanginian-Hauterivian rocks of the Rosa Blanca Formation (Carrizal and El Sapo Members) near the town of Zapatoca, Santander Department, Andes of Colombia. In addition, we describe two other fragmented teeth assigned to Strophodus sp. from the Rosa Blanca Fm. The new species from Colombia represents the only Cretaceous record of Strophodus from Gondwana, offering new insights into the paleogeographic distribution of the genus, as well as increasing the knowledge about the scarce hybodontiform paleodiversity known from South America. The presence of Strophodus in the Rosa Blanca Formation suggests that these durophagous (shell-crushing) fishes played an important role as predators of the abundant and diverse invertebrate fauna present in these ancient tropical coastal ecosystems of Gondwana.

Great white sharks may have contributed to megalodon extinction

Using zinc isotopes, researchers investigated the diet of megalodon, the largest shark to have ever lived

The diet of fossil extinct animals can hold clues to their lifestyle, behaviour, evolution and ultimately extinction. However, studying an animal’s diet after millions of years is difficult due to the poor preservation of chemical dietary indicators in organic material on these timescales. An international team of scientists led by the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, applied a new method to investigate the diet of the largest shark to have ever existed, the iconic Otodus megalodon. This new method investigates the zinc isotope composition of the highly mineralised part of teeth and proves to be particularly helpful to decipher the diet of these extinct animals.
