Microfossils? from Chile in thin section

Hello again my good friends. I did a petrographic thin section in a marine consolidated sediment, and i found some elements that seems to be microfossils. It is worth noting that these sediments are in a mandatory-way marine since in all of them are marine bivalves fragments. I also was unsure if put this here or either in the microfossil zone of the forum, leaving it here because it is an ID question. For each I'll leave a views in PPL and XPL. Hopefully someone may be able to recognize them at least broadly, and tell apart them from being forams, big diatoms or even algae. Greetings from Chile !!!!!

 

PD: Sediment age may range from middle Eocene into the Miocene
