One of the major mass extinction events of all time took place about 200 million years ago, triggered by volcanic activity associated with the birth of the Atlantic Ocean.  Elevated carbon dioxide levels at the time, led to global warming and associated environmental changes, some of which are similar to those we are currently experiencing. 

Southwest England contains some of the best locations to study the impacts of this extinction on marine ecosystems and this talk will outline some of the major advances that have been made recently.

Professor Richard Twitchett is a palaeontologist who has been researching the effects of Earth’s major mass extinction events for over 20 years.  Since 2014 he has been a Research Leader in environmental change at the Natural History Museum, London.  After graduating from the University of Bristol he completed his PhD at Leeds, and has undertaken research in the Americas, Asia, Europe & Australia, including fellowships at the University of Tokyo & the University of Southern California.

The forthcoming lecture will take place on Wednesday 8 March in the Dorset County Museum’s Victorian Hall and is FREE to the public; however a donation of £3 encouraged to cover costs. Doors open at 6.30pm and talks start at 7.00pm.
