SUMMARY:Antarctic Fossil Forests: Attack of the Insects - Claire McDonald\

DESCRIPTION:Many collections of Eocene Fossil leaves from Antarctica conta
 in a rich store of insect trace fossils\, indicating that insects were an 
 important component of the unique forests that grew in polar regions.  How
 ever\, insect body fossils themselves are rare and so insect traces provid
 e an excellent opportunity to examine both the palaeoentomology and the pa
 laeoecology of Antarctica.  The fossils studied include Eocene leaves from
  both Seymour Island and King George Island on the Antarctic Peninsula.  A
  database of all insect traces on the Antarctic fossil leaves was compiled
  and analysed in terms of the diversity of palaeoherbivory.  The fossil le
 aves are diverse with several different plant species present such as Noth
 ofagaceae and Cunoniaceae.  The range of traces found includes leaf mines\
 , galls and general leaf chewing\, of which both marginal and non-marginal
  examples are present. The preliminary results of the comparison with mode
 rn day environments in South America will be shown\, providing a greater i
 ndication of the types of insects that may have created such traces in Ant
 arctica in the past.
