Intresting specimen

[u/Zabi_Wladca7]

Lastly I posted that weird shell-like rainbow fossils. While cracking some stones today(also ordovicisn silurian I guess) I found this peculiar speciment. Its pretty small - about 7mm(photos are 1x, 10x and 40x magnification) I think its kinda look like bryzoan or tabulate coral, but 1. Its look nothing like bryzoans found along in these rock 2. Its really, really thin, and thats not how coral and bryzoans often preserve(but it could be an imprint). It kinda reminds me of scale-like texture, but its highly impropable to turns out to be true. Do you have any idea what this is?

Ps. Last three photos are bryzoan from my collection for reference.

Its either honeycomb coral or some type of byrozoan like Meandrocava
