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.



IMCC6 to be held online

In light of the challenges the global community faces from the covid-19 pandemic, we have decided change from an in-person meeting to an online IMCC6.


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!

NEW! Cancelled!

Save the date

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.



Eighth International Meeting on the enhancement and preservation of paleontological heritage, at the science faculty of El Jadida, Morocco from November 25 to 27, 2020 (visit the web page : http://www.fs.ucd.ac.ma/fs/riv3p8).

Summary: Scientists examined parts of a vertebral column, which was found in northern Spain in 1996, and assigned it to the extinct shark group Ptychodontidae. In contrast to teeth, shark vertebrae bear biological information, like body size, growth, and age and allowed the team surrounding Patrick L. Jambura to gain new insights into the biology of this mysterious shark group.
