Fossil Rock

I was cycling yesterday and came upon a pile of rocks from construction in a nearby subdivision. Some rocks contained crinoid pieces and this one has some crinoid stem pieces, part of a brachiopod, and in the middle it looks like a small star shape but I don't think starfish fossilize.

Not sure about the time period on this rock. It looks like it was dug up for a basement on a lot so the rock was maybe 10-15 feet down. In a near by area, I found a Silurian trilobite but this rock does not look the same.
