Belemnite?

[mr fossil]

I found this on a cliff in salalah Oman 

it was a jurrasic area and I found fossils coral and shells along with it but I don’t know what this is

Any idea?

thank you for your time

I think these are layered concretions that have been sectioned by weathering.

Not seeing any belemnites here.

If it were a little older I might have thought it could be fusulinid cross-sections, but they didn't survive the great extinction.
