TThille Posted October 16, 2013 Share Posted October 16, 2013 Found this in Grandpa's rock pile..he collected rocks and miscellany in his tromps throughout Central and Eastern Oregon..he has passed so I have no idea where exacty he came upon this treasure... It is 6-sided chunk of 4 to 5-sided artifaces, seemingly attached in the center of the chunk, or not...some have closed "seed pods", one has open seed pod that look like kidney bean shape, perhaps like a flower gone to seed in stages...aprox 2.5 inches each side....there is not a hole in the chunk for anything looking like a stalk or stem...rings around the outer edges of each part suggest marine life, such as a shelled creature, though since it is stuck in a nice chunk package, not sure.... Any ideas??? Thank you! Link to comment Share on other sites More sharing options...

Auspex Posted October 17, 2013 Share Posted October 17, 2013 It strikes me as an odd septarian concretion of some sort.

fishguy Posted October 17, 2013 Share Posted October 17, 2013 (edited) Looks like a thunder egg with just the agate left all the matrix is gone Edited October 17, 2013 by fishguy Link to comment Share on other sites More sharing options...
Herb Posted October 18, 2013 Share Posted October 18, 2013 A clump of barite flowers? Or the internal workings of a worn concretion?

TThille Posted October 18, 2013 Author Share Posted October 18, 2013 Thank you for your thoughts above.....would you consider a hexactinellida? or a lithostrotionella? since it is hexagonal in shape, a cluster or congregate of whatever it is for sure...the pod/seed shape in the center is curious, as is the shape as a whole...after a little internet searching, perhaps the coral? just inviting more conversation..!!!!

TThille Posted October 19, 2013 Author Share Posted October 19, 2013 Ok, after trying to wrap my brain around how a concretion might have happened, looking at the negative space,,,perhaps...in a dense colony of septaria, or i think coral still, because of the hex shape....nevertheless, thank you guys so much for your valuable input and suggestions!!!!.

Wrangellian Posted October 20, 2013 Share Posted October 20, 2013 I was thinking the exact same thing as fishguy. The material looks like the agate inside one of those thundereggs that have a star-shaped agate part when you slice them open. Matrix missing. The radiating patterns could be related to mineral growth. Not a fossil, but interesting nonetheless! Link to comment Share on other sites More sharing options...
Chapmandale Posted October 20, 2013 Share Posted October 20, 2013 Could it be a Marcasite nodule? The pattern looks similar. Just a guess. Link to comment Share on other sites More sharing options...
Wrangellian Posted October 21, 2013 Share Posted October 21, 2013 There could have been something like marcasite nodules (or another mineral with a similar growth habit) in those depressions but I'm sure there is agate in there, which filled the gap between them and the nodules have since dissolved or broken away, leaving mostly the agate.

TThille Posted October 22, 2013 Author Share Posted October 22, 2013 Thank you so much for the info, yes, many similar shapes and patterns found in things of the Old Earth.....but what of the 'kidney bean" shaped indent in the center, you can see pretty good in photo #3 above.. smooth edges and clear like someone pressed two beans into mud...and it looks like 2 beans sticking out of the mud on the direct opposite side of the concretion...legume-acite agate? Just kidding, but really, it seems organic in shape...just confusing... Link to comment Share on other sites More sharing options...
