The leaf ID looks good to me, but those who know plans better than me may have more to say. I think the object does look like some kind of pyrite crystals as you are guessing, interesting anyway!

1 & 2 is a pyritized concretion, although it may no longer be pyrite... could well now be a pseudomorph. There probably is, or was, something organic inside it. If that small round white object to the left isn't a pebble, it might be a small sponge. I would agree Neuropteris on 3 & 4

Thanks all for looking and helping me , I took the step of craking the object in pics 1 and 2 . I already have some better specimens of Pyrite, so curiosity got the better of me and low and behold the results
