DESCRIPTION:Foraminifera are a fantastically useful group of protist micro
 fossils with an unrivalled fossil record. Benthic species are present thro
 ugh the entire Phanerozoic\, but they evolved into planktonic habitats in 
 the Jurassic\, diversifying in the mid-Cretaceous. Now foram-rich sediment
 s are accumulating over about a quarter of the solid surface of the planet
 . In this talk Professor Pearson gives a personal perspective on a variety
  of foram-related topics. He explains how they are used to date and correl
 ate sediment\, how they can be tracked continuously through the strata\, r
 evealing patterns and processes of evolution\, and how their calcite shell
 s embed climate proxies\, recording a great deal of information about Eart
 h's history including temperature and carbon dioxide levels. He ends with 
 an account of the almost magical powers of agglutinated forams.
