SUMMARY:A window on deep geological time: exceptional fossils studied usin
 g new methods - Roy Wogelius\, University of Manchester

DESCRIPTION:A new area of research using state-of-the-art geochemical and 
 physics techniques to study the chemical residue of fossilized organisms w
 ill be the focus of this seminar. This effort has developed in order to an
 swer fundamental questions about the chemistry of ancient life and also ab
 out the chemical processes which allow such rare\, exceptional\, preservat
 ion to occur. These processes enable us to study such iconic fossils as Ar
 chaeopteryx\, often referred to as the first bird\, and also teach us abou
 t reaction pathways of slow geochemical reactions. This area of research i
 nvolves multi-disciplinary and multi-technique collaboration. Here\, the g
 eochemical perspective will be presented\, explaining the basic chemistry 
 and discussing the combination of techniques used including non-destructiv
 e synchrotron and infra-red methods along with more traditional methods wh
 ich involve destructive sampling. Results from recent work will then be pr
 esented\, including work on early bird and bird-like species\, dinosaurs a
 nd reptiles\, and plant material.\n
