given by Dr Susanne Schwenzer (Open University). Dr Susanne P Schwenzer is a planetary scientist, who has researched Mars geology, petrology and mineralogy since her PhD. In her talk, she will tell the story of Mars as seen from its rocks: First, there was a (warm?) and wet Mars that saw rivers flowing and lakes […]

given by Dr Peter Wigley (Consultant for Lynx Information Systems & co-author of Strata. - William Smith's Geological Maps. Strata. - William Smith's Geological Maps cover Abstract William Smith (1769–1839), surveyor and geologist, was born on 23th March 1769 at The Forge, Churchill, Oxfordshire, the son of the village blacksmith and educated at the village […]
The Chalk of Yorkshire and Lincolnshire belongs to a sedimentary basin distinct from, and yet closely related to, other late Cretaceous basins in southern England. For many years, geologists attempted to fit the southern biostratigraphy onto the northern succession; rather like fitting a square peg in a round hole!
Given by Mike Howgate (HGS). Abstract: To most interested lay-people and even most vertebrate palaeontologists the theory that birds arose from a group of Theropod dinosaurs is now regarded as an incontestable fact. However there are a handful of dissenters from this supposed certainty. I am one. I will start by outlining the position of […]
given by Dr Mick Oates (Retired: BG) Abstract: Ammonites are a popular subject, as they are both common and rather attractive planispiral fossils. So it is no surprise that they attracted interest from ancient times. The talk will cover a lot of ground, from early beliefs attached to these petrifactions dug from the ground to […]
given by Dr Colin Prosser (Principle Specialist in Geoconservation, Natural England). Rearranged from October 2020. Abstract: The UK is extremely geodiverse with many geological features and sites of international, national and local importance for research, education, tourism and recreation. However, we are a small country with a large population and our geoheritage is subject to […]
given by Tony Doré (Global Chief Scientist, Energy & Geoscience Institute (EGI) agdore@gmail.com, tdore@egi.utah.edu) Abstract: Meeting burgeoning global energy demand while mitigating anthropogenic climate change must overcome the challenges of denial and indifference, and also the negation of some genuine attempts by industry to move towards cleaner energy. Real progress will come not from blame […]
given by Dr Bethan Davies (Royal Holloway, University of London) Abstract: Understanding how the last British-Irish Ice Sheet behaved in response to external climatic forcing may be used as an analogue for how the Antarctic Ice Sheet may behave in the future. We can use these empirical datasets to calibrate numerical simulations and better understand […]
given by Dr. Neil Adams (University of Oxford Natural History Museum) Abstract: A repeated response to abrupt climate warming among vertebrates is body size reduction, which has been observed in response to anthropogenic climate change and to abrupt warming events in the geological record. Several hypotheses have been proposed to explain this size decrease among […]
