I found it in a thin section of a Jurassic-Cretaceous marine limestone which corresponds to shoreface facies.
Can it be worm tubes? a foraminifer? Any other ideas of what it can be precisely? (Photos taken with 5X objective).
I read you. Thank you.
Most probably it is the foraminifera order Miliolida
I agree with the previous answer.
This certainly looks an incomplete test/shell of a miliolid foram (the arrangement of chambers is giving the flower-like appearance).
Thank you so much for your answers. It's a big miliolid foraminifer.
Hi Linda,
It is too big size fossil, the shape of the proloculus unlike those of miliolids
