No fooling! Science Now, 20/10/04

A study in the October Geology suggests that the mineral pyrite, also known as fool's gold, could help paleontologists learn more about the body plans and innards of organisms like this Cambrian-era worm, found in the Chengjiang sediments of China's Yunnan Province. The researchers found that pyrite crystals that form in shells and slowly decaying tissues have a more geometric shape than those that form in quickly decaying tissues - a difference they hope to exploit to distinguish various kinds of tissue.
