Is this a crinoid stem?

Is this a crinoid stem? If so, what is the exterior? Thx! From Kosciusko Co, IN.

I think it's a bryozoan if I had to geuss, not completely sure. Maybe Rhombopora sp.?

BTw, it's 4 cm tall, 2 cm diameter.

I think there are two fossils here. Tabulate coral on a crinoid stem is my first guess, but I'm not that confident with either.

I agree with @Rockwood that that looks likely. The pores are too large for bryozoan. Which coral it might be depends on the age - Sutherlandia parasitica is similar but Mississippian.
