HavanaWoody Posted July 10, 2020 Share Posted July 10, 2020 This block was on a pallet of what was called corkstone that i bought to use in a pond nearly 20 year's ago, I used the rest to border my koi pond but this one was too cool to pu into the water. i had it indoors for many year's but it got moved outdoors and developed a lot of moss, ,while it still looked cool i recently hit it with a pressure washer revealing more than had shown prior and since have become more curious about the center dis and cluster of spines. this morning I used a little sandblasting to erode the backside and this is what i have. I have no way to know were it came from,and suggestions? is it already too cool to mess with furthermore or do you think there's more to be seen?

HavanaWoody Posted July 10, 2020 Author Share Posted July 10, 2020 A couple of close ups, sorry big file's Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 10, 2020 Share Posted July 10, 2020 Welcome to the Forum. Looks like a concretion in the middle of that. Neat looking piece, I agree. I'd be interested in seeing the "spines" up close. They may be fossil-related. I tried to brighten and enlarge yours, but the detail gets washed out.

Fossildude19 Posted July 10, 2020 Share Posted July 10, 2020 Almost looks like a cidarid echinoid, but the oval shape is throwing me off, ... unless it is an imprint of 2 in close proximity. 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

TqB Posted July 10, 2020 Share Posted July 10, 2020 (edited) There's definitely at least one disarticulated cidarid in there.The spine outlines, and interambulacral plates with bosses, are clear. Mostly or all decalcified, just impressions. Edited July 10, 2020 by TqB 4 Tarquin Link to comment Share on other sites More sharing options...

I ran out of upload space, Don't know if It resets but let me see if I can add the close up of the spines, they are definitely interesting. 2 Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 20, 2020 Share Posted July 20, 2020 Phenomenal photo! Thanks for posting that. I agree with TqB. Looks like the imprint of a disarticulated cidarid echinoid, with spines. That is very cool. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

HavanaWoody Posted July 20, 2020 Author Share Posted July 20, 2020 Yeah I see, the other images don't do justice, the concretion is lens shaped and sharp Edges, i wish i had an xray of it. Link to comment Share on other sites More sharing options...
TqB Posted July 20, 2020 Share Posted July 20, 2020 (edited) I wonder if it's Carboniferous? That looks as if it could be Archaeocidaris, which I think disarticulates more easily than Mesozoic and later cidarids. It's very beautiful and well worth rescuing from outside, whichever it is! (At the moment, the concretion is less interesting, though there could be something good inside it…) Edited July 20, 2020 by TqB 2 Tarquin Link to comment Share on other sites More sharing options...

This is a Paleozoic cidaroid. 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
