Upcoming Meetings:




The 2nd Palaeontological Virtual Congress will be organized in a number of general theme sessions trying to span the whole variety of potential contributions.

However, Palaeontology is a wide discipline which encompasses a huge variety of topics.  Aware of this and taking advantage of the flexibility that virtual platforms offer, sessions proposals on emerging topics, innovative techniques or any other matter that you consider of interest are welcome to be addressed in depth during the celebration of the congress.

The purpose of such sessions is to provide a comprehensive forum for the exchange of ideas and discuss the issue within specialists in the target field.

If you are interested in proposing a specific session, please send us a brief description (no more than 300 words) with the main goals and any relevant information that you may consider relevant. Please, indicate in the proposal the full name of the organisers and their respective affiliations.

Proposals should be submitted by email to palaeovc@gmail.com before December 31st. Notification of acceptance will be sent to the organizers after that.  This edition, we want try to involve more to the participants, so if your workshop is accepted, the proposed organisers will be in charge of: 

– Look for contributions. Ideally, a single session would require the participation of at least 5 contributions, but this is only a suggestion and it is not mandatory.

– Send the abstracts to peer-review

– Moderating the sessions. We want to encourage a dialogue with all the participants, so the sessions organisers will be in charge of moderating and promoting debates in the discussion chats.



The 6th International Marine Conservation Congress

To conserve the world’s oceans we must go beyond science and use it to inform policy and management to catalyze change. The International Marine Conservation Congress (IMCC) brings together conservation professionals and students to develop new and powerful tools to further marine conservation science and policy.

With over 700 marine conservation professionals and students in attendance, IMCC is the most important international event for anyone involved or interested in marine conservation. The meeting brings together marine conservationists from many walks of life including but not limited to scientists, practitioners, educators, policy-makers, artists and journalists.

IMCC6 takes place in the sailing city of Kiel, Germany. Join us in Kiel as we come together to help Make Marine Science Matter!

next meeting: July 22-26, 2020 (Dates subject to change)    Norfolk, VA



A space for the dissemination of knowledge and interaction among researchers interested in sharks, rays and chimeras, both in Colombia and in Latin America. It is done every two years and since 2008 six versions have been made.

It will be held at the Pontificia Universidad Javeriana de Cali, Colombia,
from July 6 to 10, 2020.

ANDREEV, P.S. & ZHAO, W. & WANG, N.-Z. & SMITH, M.M. & LI, Q. & CUI, X. & ZHU, M. & SANSOM, I.J. (2020): Early Silurian chondrichthyans from the Tarim Basin (Xinjiang, China). PLoS ONE, 15 (2): e0228589

New order: Sinacanthida

New genus: Taklamakanolepis, Tielikewatielepis, Yuanolepis,

New species: Taklamakanolepis asiaticus, Yuanolepis bachunensis, Tielikewatielepis sinensis, Xiaohaizilepis liui

Abstract: The Sinacanthida ordo nov. and Mongolepidida are spine- and scale-based taxa whose remains encompass some of the earliest reported fossils of chondrichthyan fish. Investigation of fragmentary material from the Early Silurian Tataertag and Ymogantau Formations of the Tarim Basin (Xinjiang Uygur Autonomous Region, China) has revealed a diverse mongolepidid and sinacanthid fauna dominated by mongolepids and sinacanthids in association with abundant dermoskeletal elements of the endemic ‘armoured’ agnathans known as galeaspids.

Micro-computed tomography, scanning electron microscopy and histological sections were used to identify seven mongolepid genera (including Tielikewatielepis sinensis gen. et sp. nov., Xiaohaizilepis liui gen. et sp. nov. and Taklamakanolepis asiaticus gen. et sp. nov.) together with a new chondrichthyan (Yuanolepis bachunensis gen. et sp. nov.) with scale crowns consisting of a mongolepid-type atubular dentine (lamellin). Unlike the more elaborate crown architecture of mongolepids, Yuanolepis gen. nov. exhibits a single row of crown elements consistent with the condition reported in stem chondrichthyans from the Lower Devonian (e.g. in Seretolepis, Parexus). The results corroborate previous work by recognising lamellin as the main component of sinacanthid spines and point to corresponding developmental patterns shared across the dermal skeleton of taxa with lamellin and more derived chondrichthyans (e.g. Doliodus, Kathemacanthus, Seretolepis and Parexus).

The Tarim mongolepid fauna is inclusive of coeval taxa from the South China Block and accounts for over two-thirds of the species currently attributed to Mongolepidida. This demonstrates considerable overlap between the Tarim and South China components of the Lower Silurian Zhangjiajie Vertebrate Fauna.
