Crinoid (?) - found in yard

[SkateKraft]

Found in my yard in Dorchester, Ontario on the Thames River.  I've found several of these in my yard. Is it a crinoid?  I'd sure love to know what an experienced fossil hunter would call it, as well as what era it might be from.  Looks like there is one large one through the rock, with other little things in there.

Some of the smaller things are likely pieces of crinoid. Fragments of coral seems more likely for most of those that are visible though. Sometimes the shapes with no distinct features are just clay balls, or other clasts that were caught in a sedimentation event. (storm, slide, or the like). The files are a bit small to tell for sure.

Thank you, Kane, for the ID, suspect age and the chart!  Much appreciated -
