Ruger9a Posted February 19, 2020 Share Posted February 19, 2020 Is this just another concretion? It was listed as Dinosaur Seed Fossil Specimen, Pennsylvanian, found in Illinois. I am suspiciously thinking it's another concretion. Am I right? 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 19, 2020 Share Posted February 19, 2020 Yes, I think so. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Ruger9a Posted February 19, 2020 Author Share Posted February 19, 2020 Ha, I was right.... Thank You Tidgy's Dad. My unidentified concretion drawer is now almost overflowing and my seed pod drawer is much more roomier. I'm really happy I have finally got these identifications correct. Thanks again. 1 Link to comment Share on other sites More sharing options...
digit Posted February 19, 2020 Share Posted February 19, 2020 Yup. A classic looking multi-layered concretion with what appears to be some slight tessellations like it was trying to be a septarian concretion. https://en.wikipedia.org/wiki/Concretion#Septarian_concretions Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
Ruger9a Posted February 19, 2020 Author Share Posted February 19, 2020 Thanks Ken! Looks like I have a "baby" concretion compared to the other photos, LOL. But, at least it's a "classic"...… Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted February 19, 2020 Share Posted February 19, 2020 Looks like Mazon Creek (Illinois) material. A few (dozen) freeze thaw cycles may cause it to split and reveal something more interesting. Or possibly not. Dinosaur seed? Pennsylvanian Preovasaur? Edit: It's not a MC seed of any species. Mark.

Ruger9a Posted February 19, 2020 Author Share Posted February 19, 2020 Yep Bobby, at the current time I believe "the concretion collector" may be me....by proxy. I do have a few nice ones including this one. I popped it open and it was full of sand so I got this "great" idea and stuck a fossil inside so it looks like an embryo. This is just for my amusement mine you, but I can't help pulling the leg of my friends and grand children by telling them I'm waiting for dinosaur baby to hatch :-) I am wondering what the fossil inside is though.

I laughed when I saw the listing but I thought it was interesting. And who knows, it "might" actually turn out to be a seed pod or something else "special". The low cost helped make up my mind. Yep it is something special - a baby concretion... I may put it right next to the one above and tell folks it's a dinosaur seed and if I plant it, it will grow me a TRex.

I would freeze/thaw it. Those little ones often have small single pinnules beautifully preserved. I have opened several dozen less than 2cm length that had most excellent specimens. 1 Mark.

Ruger9a Posted February 19, 2020 Author Share Posted February 19, 2020 Wow, I thought you were joking. I've never done a freeze/thaw process, what would I have to do? 1 Link to comment Share on other sites More sharing options...

Soak it in tap water for about a week, or until the water has permeated to the center. That's why about a week is recommended for smaller specimens. Freeze it immersed in water in a small container overnight. Let it thaw during the day. Check after each thaw to see if it has split open. Repeat. If it doesn't split within 25 cycles it probably doesn't contain a fossil, but I have had some go 70+ cycles before splitting. Good Luck, I hope you get something nice. It would be a good joke on the seller. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
Ruger9a Posted February 19, 2020 Author Share Posted February 19, 2020 Thanks Mark! I'll try it. After all what do I have to lose? I'll let you know if I find something. 1 Link to comment Share on other sites More sharing options...
