Valett Burrous Posted October 14, 2017 Share Posted October 14, 2017 Found in an old railyard. I don’t know much about fossils, I just pick up cool rocks. Link to comment Share on other sites More sharing options...
mkspsa Posted October 14, 2017 Share Posted October 14, 2017 Looks like a concretion. I would say not a fossil. Link to comment Share on other sites More sharing options...

Rockwood Posted October 14, 2017 Share Posted October 14, 2017 I agree that it is a concretion. It may not be that simple though. If you give a better location. (It need not be precise.) Someone may be able to give better odds that it formed around a fossil. It happens. Link to comment Share on other sites More sharing options...
fifbrindacier Posted October 14, 2017 Share Posted October 14, 2017 I agree it's a nodule concretion, but i wonder about that clearer thing that can be seen in the center. Maybe could you crack it open to see if there is something fossil in there or no. Regards. Sophie. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

Valett Burrous Posted October 14, 2017 Author Share Posted October 14, 2017 Found in central Illinois. Yailyard is surrounded by corn/bean fields. The center isn’t clear. It’s just different in color. More yellow tones, less grey. Link to comment Share on other sites More sharing options...

Valett Burrous Posted October 14, 2017 Author Share Posted October 14, 2017 What is the next step I should take with this? Crack it, cut it, toss it in the rock pile? Link to comment Share on other sites More sharing options...
coled18 Posted October 14, 2017 Share Posted October 14, 2017 @Valett Burrous I would say to polish it, it looks like a neat display piece. There are tons of ways to polish rocks and minerals, just look it up on the internet. PS when you see an informative post, be sure to hit the shark tooth button in the lower right hand corner.

Does not look right for a fossil bearing concretion to Me, but You never know unless You look. Crack it open with a hammer. Darwin said: " Man sprang from monkeys."

I would say wait. Someone who knows the Mason Creek concretions should be along before too long. Tony: no offense if you know them. Your post wasn't up yet.

Fossildude19 Posted October 14, 2017 Share Posted October 14, 2017 Doesn't look like the typical Mazon nodules posted here. I would try the Freeze/Thaw method however. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Valett Burrous Posted October 14, 2017 Author Share Posted October 14, 2017 It was very brittle so I used a hammer with light blows. Here is the inside. Keep going? 1 Link to comment Share on other sites More sharing options...
Rockwood Posted October 14, 2017 Share Posted October 14, 2017 Not with a hammer unless you just want to see broken fossils. These are Mason Creek fossils like I said. Wait for it. Link to comment Share on other sites More sharing options...

These are fossils, but not the kind famous as the Mazon Creek fossils. These are common from all ages and more three dimensional. You may be able to prepare them some way, but I can't advise further. s/z joking If there is a Mason Creek it's a coincidence. Link to comment Share on other sites More sharing options...

Rob Russell Posted October 14, 2017 Share Posted October 14, 2017 I would soak it in water for a day, and then freeze it solid submerged in water. Not much. Just enough to cover it with water, and freeze solid. Thaw it a day or two later. See if it splits naturally on its own. If there's a fossil inside it may split on the plain of the fossil. If you strike it with a hammer you may smash it to bits. Good luck. PS. If it doesn't split the first time repeat freeze/thaw process several times if necessary. 1 Finding my way through life; one fossil at a time.

Actually, it does resemble nodules I've found in the braidwood biota. (Terrestrial sediments). Perhaps a glacial erratic? Not out of the realm I suppose. Actually, there are areas in central and southern Illinois where Pennsylvania aged plant fossils can be found. Other coal mines. Finding my way through life; one fossil at a time.
