Hyoliths: where they fit in
By Dr Martin Smith, Durham University. Join us for an interesting and informative evening! Non-members are welcome free of charge. For over 250 million years, the conical shells of hyoliths littered the fossil record, but at the End Permian Mass Extinction they entirely disappeared.

Control the drainage: The gospel accorded to sinkholes
Talk by Dr Tony Waltham. Join us for an interesting and informative evening! Non-members are welcome free of charge.

Its impact on engineering geology is the distinctive suite of karst geohazards, which are largely related to the holes in the ground of varying size and unpredictable nature. The most widespread and frequent geohazard is the development of new sinkholes within the soil…

This talk will discuss research from the last twenty years that has provided new sites, better dating frameworks, rich environmental information and a…
