SUMMARY:Dominic Davey - Edward Charlesworth: Geologist\, Controversialist
DESCRIPTION:PLEASE NOTE THAT THIS MEETING IS BROUGHT FORWARD TO THE 1ST MONDAY OF THE MONTH TO AVOID OUR FIELD TRIP THE FOLLOWING WEEK \n\n\n\n\n\n\n\n\n\n\n\n\nEdward Charlesworth (1813–1893) was a notable 19th-century palaeontologist\, geologist\, curator\, inventor\, fossil dealer\, and scientific controversialist. Raised in Suffolk\, he developed an early interest in fossils and geology\, producing an important paper on the Crag deposits of East Anglia in 1835 and becoming a Fellow of the Geological Society of London at just 22. After abandoning medical training\, he held curatorial roles at the British Museum\, the Zoological Society of London\, and later the Yorkshire Museum\, while also editing and founding natural history journals and societies. His career was marked by ambition\, heavy workloads\, financial difficulty\, legal trouble\, and public controversy. Following his resignation from the Yorkshire Museum in 1858\, Charlesworth never again held a salaried post. He supported himself through fossil dealing\, consultancy work\, museum cataloguing\, public lecturing\, scientific societies\, and inventions\, including the commercially successful “Elevator Gun.” He catalogued collections for several museums\, revived the British Natural History Society\, and distributed thousands of fossil sets to subscribers. In later life he moved to Saffron Walden\, where he remained active in local scientific and cultural life until his death in 1893.\n\n\n\n\n\n\n\n\n\n\n\n\n  \n\n\n\n\n\n\n\n  \n\n\n\n\n\n\n\n\n\n\n\n\n\n

SUMMARY:Dr Peter Sheldon - Exceptional fossils – the Surprising\, the Significant and the Strange’
DESCRIPTION:An ever-growing range of extraordinary fossils is shedding new light on the history of life: colour patterns in dinosaur feathers and insect wings; DNA from an ecosystem two million years old; the love song of a Jurassic cricket\, to name but a few. Medical imaging techniques and particle accelerators make it possible to see inside the rock surrounding rare and fragile fossils. Peter’s talk will include some remarkable\, and often surprising\, finds from many parts of the world.

SUMMARY:Kevin Purvis - Some Like it Hot – A Near World’s End Experience. The Permo-Triassic Extinction Event
DESCRIPTION:(PTEE) \nThe Permian-Triassic Extinction Event (PTEE) (c. 252 Mya) was the most severe extinction event that the Earth has experienced\, with over 80% of the marine species and 70% of terrestrial species becoming extinct. The extinction event was the result of catastrophic climate change that occurred during a period of Permian warming and resulting in the Triassic Hothouse. The talk will outline the PTEE\, but also the details of minor climate change that occur as perturbations throughout geological history. Analysis of carbonate cements related to plants that grew during the post-extinction period of recovery give an insight into what the surface temperatures were like\, millions of years after the event. The use of U-Pb age dating and isotopic analysis help in our understanding of past climatic change.
