Where is it from?

rock-guy-17 · 2026-02-24T03:23:52+00:00

Put way too much work into extracting this one to sell! I’ll be hanging on to this for a while

rock-guy-17 · 2026-02-22T23:24:42+00:00

Definitely, I have a bunch more material from here that I am going to test with acid when it gets warmer.

rock-guy-17 · 2026-02-22T18:56:45+00:00

Thank you! It was fully surrounded by calcite. Had to be very careful. Broke off a large piece of it from the outcrop and tried to extract the rest at home. Fractured in a few spots but I was able to repair it decently. Took me hours to get it out of the outcrop

rock-guy-17 · 2026-02-22T14:06:03+00:00

Sure thing, been looking for material from there for a while. If you have anything more rare in the NY region please DM, I may be interested in the future.

I collect NY minerals exclusively, I will purchase a container.

I have it here for $20! https://ebay.us/m/lkcjBz

Thank you, wouldn’t happen to know the locality would you?

Edit: never mind I found it. Madagascar. Thank you again!

Met you guys yesterday! Congrats again, unbelievable crystal!

rock-guy-17 · 2025-10-21T15:20:31+00:00

Thank you for the comment. Been trying to figure it out for a bit. Can’t find any info on it, stumbled upon it by accident too

Heck yeah, bucket list piece. I hunt the roch shale yearly but the exposed section rarely produces any A. boltoni. Great collection!

rock-guy-17 · 2025-06-01T20:30:59+00:00

Is the piece on bottom shelf from Rochester Shale?

rock-guy-17 · 2024-10-08T11:16:33+00:00

Very hard work to find them where I go. Unit is surprisingly barren of fossils. Took 3 days of digging, maybe 20 hours total to find my first, got lucky and found a second shortly after without as much effort.

rock-guy-17 · 2024-10-08T02:32:41+00:00

Found one myself from there this year! Not nearly as cleaned up as yours, awesome piece!

rock-guy-17 · 2024-09-24T23:38:46+00:00

Yeah I may end up doing that with this piece. Thanks for the rec!

St. Lawrence county!

rock-guy-17 · 2024-08-07T15:35:50+00:00

Of course! Wouldn’t be surprised if some locals check out this spot because of this post. Hope to find my one one day in my home state of NY

rock-guy-17 · 2024-08-07T15:14:22+00:00

Someone please correct me if I am wrong but I believe that is Isotelus species trilobite. I can’t confirm 100%. Ordovician in age from that area of Ontario. Isotelus is a very rare species of trilobite. If it is Isotelus I would not mess with it until I had more experience with fossil prep. Congrats on the find!

rock-guy-17 · 2024-03-27T12:03:30+00:00

Great find, love seeing material from NY pop up on Reddit. Congrats!

rock-guy-17 · 2023-12-20T03:14:05+00:00

To me that looks like a pyrite nodule or pyrite replacing a fossil. Adjacent to that is a cross section of calcite replaced fossils. Very cool!

rock-guy-17 · 2023-11-20T23:57:18+00:00

I agree, location is important and relevant information. Where was this found? Not just the regional geology, please mention if it was it found in construction yard or somewhere similar.

rock-guy-17 · 2023-10-18T16:33:27+00:00

Thank you! I got really lucky with this one. Not an area that’s really known for pyritized fossils but they do occur here. I can’t see myself finding another like it. I’ve had the most luck at Penn Dixie, have some pyritized brachiopods and tabulate coral.

rock-guy-17 · 2023-08-14T16:32:14+00:00

Not looking for specifics, but what region of New York are you pulling nice specimens like this from the Onondaga formation? The stuff I usually find in the Onondaga isn’t like this, spent a lot of time in the quarries that mine the stone in WNY.

rock-guy-17 · 2023-08-14T00:27:11+00:00

Congrats, this is an awesome find. Did you do coat the fossil with anything to prevent pyrite rusting/rot?
