Is this bryozoan or just rock

[0lderthandirt]

Hello again,

I found these 2 rocks this morning on my property. Redwall limestone, Mooney falls member, Arizona, Mississippian. 

I think the tiny branch looking thing might be bryozoan and I don't know if the bumpy rock is anything at all. What do you guys think, are these just weathered rocks?

Sorry. I think these are.

Thank you for the input! I usually don't pick that stuff up but it's a sloppy snow/mud day so I thought doesn't hurt to drop them in my pocket and post some pictures.

Thanks again

I know the feeling.
