I recently came across a Sept. 20 NYTimes article about fossils uncovered in Cuba. http://www.nytimes.com/2005/09/20/science/space/20mete.html?ex=1129089600&en=9bc3670e4e036958&ei=5070

 It included the following paragraph:

"Microscopic study also revealed the presence of thousands of tiny fossil creatures, most especially foraminifera. Those one-celled animals have a bewildering array of minuscule shells. Forams, as they are known, evolve so fast that geologists, paleontologists and oil companies use their shifting appearance as reliable guides to geologic dating.

"They told the age of the sediments," Dr. Alegret said. "So we've definitely confirmed the age of these deposits."

I'm not familiar with forams or their use for dating. Can someone on this list please provide a brief tutorial about this technique or point me to a useful link?
