Great post! One question I have is what do you want to find out? Location
or the dead critter or what environmental differences their were. Some SEM
would be very valuable but polarized and DIC could be quite valuable
particularly were the environmental stuff is. In my experience
micro-paleantologist use a brightfield or DIC 'scope. This is a "for what
its worth" post since I don't have a lot of micro-paleatological customers.

Let us know how it goes.
