Fossil diatoms

I'm looking for (sub) fossil material from all over the world.
If you have fossil material for sale or if you have something to exchange, please contact me on the contact tab above.
I have subfossil material from the Netherlands, with a lot of different and interesting diatoms.
The type slide that you see below, is from the fossil material found near Renkum (Netherlands).
