Paleonet: incertae sedis

[brcgranier at free.fr]

Dear Colleagues,

I would like to have your opinion (if any) on the attached pictures of 
groups of "calcispheres" (the scale bar is 100 µm), which are associated 
to calpionellids. Did you already observed similar material?

I look forward to receive some feedback from you =)

Bruno Granier
