Oh, well spotted. It's obvious now you say it but we all had the wrong eyes in at the time - that'll make Peter happy.

Welcome John (fossilcrazy) ! Good that you are here on this board.... With regards to the last colorful specimen... the idea of bone is interesting but I have yet to see bone in the anoxic shale deposits at Kettle Point... most placoderm material is found in limestone rather than shale at this location....

My thinking it is still bone and I'm sticking with it. On the other side of Lake Erie (USA side) is similar Upper Devonian Black Shale with Callixylon newberryi and boney plates of Arthodires. Same fabric patterns, but different coloring (black carbonized bone with white Calcite infilling) I can post pictures of the Plants and you would not be able to distinguish the two.
