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 […]
Leaders: Peter Ablett and Paul Jennings Over the years the River Bulbourne has been heavily compromised by historical changes. In 2013, in conjunction with the Environment Agency and other interested parties, the Box Moor Trust embarked on a restoration project for the Bulbourne. 09:45 meet at Box Moor Trust Center (HP1 2RE) Walk through the […]
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 […]
A field trip in search of Calcrete, Silcrete and Ferricrete in South hertfordshire, led by Mike Howgate. Calcrete cliffs at Waterford Heath We will meet up in the car park at Waterford Heath Nature Reserve which is just north of Hertford ( O.S. TL 317150 ) at 10.30 am. This is a small car park […]
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 […]
From bones to pixels – using computer technology to understand the behaviour of fossil animals
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 […]
