Anyone have any idea what this might be? Was found last week while splitting Widder shale looking for Greenops. I usually don't take much home other than trilobites but I have never seen anything like this before. From Hamilton group, Widder formation, was found alongside Greenops bits. Any ideas would be appreciated. Thanks!

Just got back and am beat from a day at Arkona. This one is a bit strange. Just when I think I've seen every odd pattern, ichnofossil, mineralization, and concretion type in the Widder shale, I get a curveball. Or should I say a snowflake?. specs: Mid Devonian (Widder Fm). Arkona, Ontario. About an inch. I can't seem to find it, so this pic was taken in the field. I might have lost it.

Not knowing for sure at that moment, and not wanting to spend valuable collecting time deliberating on it when I had a lot of shale to move, I simply put it in the bucket so that I could take a closer look when I got home. My question for those who know more about taphonomy and such would be this: can anyone tell me a bit more on the processes that produce this kind of nodular form? The concentric patterns are

Specimen collected from the north exposure of the Ausable river, westbound from the northern pit of Hungry Hollow owned and operated by Brampton Brick. Specimen (prone) complete and intact save for some minor pleural damage on the right side. Specimen retrieved whole with matrix. Preliminary preparation by K. Faucher to remove bulk matrix cover. Second preparation by Malcolm Thornley using a Comco abrasion unit at 7 PSI, with dolomite as the abrasion substance through a 320 mesh screen, 0.15 nozzle and subsequently 0.10 nozzle for more intricate matrix removal.

Not something I find very often. Thinking it might be bryozoan, but unsure. Mid-Devonian, Widder Fm, Hamilton Gp. Any help is appreciated to ID this one so I can properly catalogue it.
