I have been busy on other lists and basically ignoring this one(I know I should hang my head in shame).  Forams are few in number, many float on the ocean currents and are thus spread around the world. As they evolve, they make a layercake pattern of different forms in all the oceanic sediments.  There are not many more than about 150 total species of forams in all the history of the world. Today there are 44 living species.  To me this is one of the best arguments against the global flood.  Why would a turbulent flood sort these creatures all over the world by the decorations on their shells.  see

We use forams in the oil industry to tell us where we are when we are drilling.

Thanks, Don.  And I enjoyed reading Jim's links.  It's fascinating but I still have lots of questions.  I understand the observation of the sequence of species over time for these plankton.  It is certainly amazing to see the progression and the fairly precise dating that can be done.  But I couldn't find anything about the driving forces.  What environmental factors drive natural selection for plankton?  Have oceans change so much and so rapidly that over 66 million years it drove such changes?  And why is the rate of change relatively constant?  (if it is, of course.  I couldn't tell for sure from the snippets I read)  How are the differences in the sequential species affecting the ability of plankton to survive?
I think what you are seeing is basically genetic drift in the forams.  That would explain the rather constant rate of change.
