Working With The Burgess Shale
The fossils of the Burgess Shale are preserved as black carbon films on black shales, and so are difficult to photograph; however, various photographic techniques can improve the quality of the images that can be acquired. Other techniques include backscatter SEM, elemental mapping and camera lucida drawing.
Once images have been acquired, the effects of decay and taphonomy must be accounted for before a correct anatomical reconstruction can be made. A consideration of the combination of characters allows researchers to establish the taxonomic affinity.

Famous quotes containing the words working and/or burgess:
“Americans have internalized the value that mothers of young children should be mothers first and foremost, and not paid workers. The result is that a substantial amount of confusion, ambivalence, guilt, and anxiety is experienced by working mothers. Our cultural expectations of mother and realities of female participation in the labor force are directly contradictory.”
—Ruth E. Zambrana, U.S. researcher, M. Hurst, and R.L. Hite. “The Working Mother in Contemporary Perspectives: A Review of Literature,” Pediatrics (December 1979)
“We all need money, but there are degrees of desperation.”
—Anthony Burgess (b. 1917)
