plant fossils

[Wilson, Rachel]

In my plant biology class next semester I am planning to have the students
prepare peels of coal balls.  We have done this in the past, but I would
like to do more with the peels this year in terms of examination if at all
possible.  Can anyone recommend reference(s) that may include pictures of
(presumably) spores, stem bits, etc. of some of the major taxa one would
find?  Comments regarding feasibility also welcome as I am not a
paleobotanist!
