I study silicoflagellates and have a particular taxonomic question for which resolution would require a rare double skeleton (see attached) from the type species (Corbisema geometrica) of a genus described from the Moreno formation. I hear that you have studied laminated sediments from this formation; would microscope slides showing siliceous microfossils be available? I hope that these laminated sediments might improve chances of discovering a double skeleton. Can you contact me at [email protected]? I am presently on a sabbatical at the University of Szczecin, Poland. Kevin
