I was surprised to learn that turritellia(elimia) agate comes from the Green River fm. It seems surprising that such radically different matrices are present in the same formation. Does anyone know the association, are there clumps of agate mixed in with green river fish/leaves/etc or are they isolated deposits that got lumped in together due to similar age and location? *edit*: Also, Eden valley wood/algae and giant stromatolites. Truly a diverse formation

Need help confirming what I found. This speciman was found in Milwaukee, WI. I found it in some loose landscape rock around the building I work in. Unfortunately I don't have a ruler on me right now but it's about 2 inches long and 3/4 inches wide. Originally I thought it was agate but someone in my rock group on Facebook says it looks to be silicified stromatoporoid. After doing a Google search I came across stromatolites also. So I'm not sure which one it could be. It's a beautiful specimen. What looks to be quartz on the bottom and what I originally thought was agate surrounding it. Any ide

I found this in an abandoned fish nest in a human-made lake. One of my favorite finds!

There are cross hatch patterns in the wood making it almost look woven. The rock imbedded in it or attached to it looks like amber. its bright yellow and dark when no light is behind it. The amber or agate looks like it has some of the same fiber pattern around the edges.

I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix

Any Ideas on this?

Found in Michigan LP. Devonian age probably? Loads of corals and other agatized fossils wash up on that beach. This is the only one I’ve found like this.

Stromatoporids, other sponges, or not a fossil? Thanks!

All collected in gravel and beach rocks from SW Wisconsin. Thanks so much for the help! I love this community:) -
While rockhounding 20 miles north of Utahs veyo volcano, in a basalt strewn field, my son and I came across what we thought were two rocks that may be fossils. One looks to be a piece of agetized bone. The other not so sure. We would appreciate your assistance in determining if they are anything more than what we originally thought. Thank you.

I live in Richmond, Virginia and recently discovered a bounty of agates in my back yard. Here are pictures of one I found yesterday that is different from all the others. There is still some dirt/mud from the garden in the crevices. I stopped cleaning it after seeing bits of druzy quartz along a seam in the agate and wondered if it could possibly be a fossilized head of some sort? I looks like it spent some time tumbling in a creek or something of that nature (most of the other agates are rounded Patuxent stone types). Also, I apologize for not including a metric ruler, but I've included a pic

Howdy, I was wondering if anybody could tell me what they think about these rare coral fossils that I find on the Oregon Coast. They are agatized and take a nice polish. Thank You

Found this fossil in an agate of unknown age from a gravel pit ...

I think it looks shockingly similar to charnia. Maybe a cephalopod, snail, or plant? What could it be? -
Is it a "Turritella Agate" - chertified fossiliferous lacustrine limestone in the Eocene of Wyoming, USA.or a sample from Brazil or Madagascar? -

From the album: fossil wood
giant slice of fossil wood with pink and brown color. Pink, as I think, is rare..., have not seen many of them. This comes from Arizona, near petrified forest, from an old collection. Size is around 80 cm, this is nearly 34"© fossils worldwide

I found this really interesting rock while cleaning my pond over the weekend. The pond is lined with round river rocks (presumably mined here in Oregon) and this one caught my eye as I was cleaning. When I looked at it a little closer, it appears to be petrified wood with some type of bore holes. Some of the bore holes are filled with what looks like agate and others have what one might imagine a dried out petrified worm might look like. I looked at it under magnification and noticed what looks like a couple of very small (<1/8") fossils. The clearest one is in the center of the first photo

Folks on mindat.com suggested asking this question here! This is less of a "what is this a fossil of" question and more of a "is this possible" question. I have a small chip of translucent chalcedony showing a mass of white inclusions, two of which look very much like a grass seed-head. The gist of the conversation so far has been 'is it possible for fossil material to be an inclusion within a silica mineral like agate or chalcedony?' As opposed to an agate-replacement or opal-replacement fossil like an agate limb cast, agatized wood or agatized/jasperized opaque mudstone with intact fos

Hello TFF, I purchased this relatively inexpensive specimen at Mineralfest this past fall, and I was wondering if anyone could tell me more about it. The seller informed me it could possibly be from Madagascar, but was transparent in admitting that she couldn't confirm for sure. It was with other pieces of petrified wood that were brown, but I was drawn to this one due to the red hues. I think it's agatized, and it looks "glassy," although there are too many impurities to shine a cell phone light through it. One side is polished, and I put water on the rougher backside to show mor -
Found in landscaping bed in south Texas I think it could be a solitary coral.

Found in a small Yellowcat wash, outside Moab, UT while scouring for petrified wood. Not near a uranium mine. Partially exposed and nothing else like it around the area all day. The wash was in Morrison material. About 3” x 5”. Super shiny even without washing. Thanks!

Hi guys, avid rock hunter here, brought home this “thunder egg” from crater of diamonds in Arkansas a few years ago. I finally got a slab saw and it’s not what I expected! It’s semi transparent in spots and some druzy inclusions. Some areas seem a little oolitic? Could it be an “agatized” fossil of some sort?
