I recently bought an unpolished turritella agate slab from a friend & he included an end piece with it. I was looking at a broken area of the end piece with my loupe and saw something that got me curious. So... I fired up my Dino-lite and ended up even more curious. The agate filling some of the shells looks almost like it is comprised of beads. From what I've seen online, it seems to be a common thing, but I haven't found any explanation of it. Pics 1 - 4 are from the rough broken section on the end piece, the 5th is from the slab itself (still not polished, just wet). Any ideas? I think it's quite pretty, but it's being an unknown (to me at least) has my mind clamoring for an answer.

Hi. Is this a geode if the walls are smooth? I only have half of this 6lb piece but I have never seen a smooth inside of a geode, only covered in druzy.

This fossil was found on a Gold Coast beach in 2019. I'm thinking Pliocene as it's like most of my beach fossil finds. It's a curiosity as it has some crystals inside the carapace. Any thoughts on this? Thankyou!

Is this gold in this Medicine Bow Dendrite Agate, or pyrite in the plumes? I looked through a magnifying glass and it didnt appear to be pyrite. The dust is to small to tell. Any help would be appreciated.

I have a rock that I cut in half and need info on please. I have asked once before when it was completely raw, without any work done to it. It is Jasper with purple Agate? The pattern on it is puzzling. Thank you for any help

Hi. I have cut and trimmed this Agate with some polishing to reveal a few neat things. It is a botryodial moss agate, with water lines? Can you help me identify the species? Unknown origin. Thank you.

Here are some more photos submitted for your viewing pleasure. The specimens aren't all rocks and minerals, per se, since three of the five are petrified wood. I haven't researched the PW specimens in an attempt to determine the type of original wood. All were found by myself or a running buddy within the past couple of weeks. The area found was in San Juan County in northwestern New Mexico, Upper Cretaceous, Kirtland Formation on B.L.M. land. The second and forth specimens is a type of brecciated agate / jasper mix I call New Mexico Brawn. They were found in the same area but were colored so very differently from each other. The first, third, and fifth specimens are fossilized wood. An interesting thing about the first specimen is that it is uncut and just as I found it, with agate almost as clear as glass. Hope you enjoy looking at these.

Some petrified wood found in northwestern New Mexico, San Juan Basin, Upper Cretaceous, Kirtland Formation a couple of weeks ago. The cut slabs are from a log about 6-inches in diameter and my best guess is conifer only because most everything else in that area turns out to be conifer, specifically, Cupressinoxylon sp. Any other opinion about species would be welcome. There are several nice agate bands running through the length of the log and are clearly visible here. The first slab is dry and the second is wet.

Here are some rocks I cut up in my saw last night - just wanted to share. All were found in the Four Corners area of the U.S.

The following are some pseudomorph minerals I cut open on my saw last night. I'll show photos front and back of the two specimens, each of which are several inches long. To me, they both appear to be quartzite or florite after barite, but I'm not really a mineral guy so I would happily defer to anyone that can describe them better. Thanks for the help.

Here are several more rocks I cut open today and was pleased at the results. The first three were collected at various locations between Utah and Arizona. 1. The first photo I would call a landscape agate with (use your imagination here) a scene on an alien planet during a crazy lightning storm. On the right side there was an indention in the surface, however, it was filled with perfectly clear agate like a window. 2. The second photo is known as St. John's (Arizona) Flower Agate. 3. The third photo shows some lovely botryoidal and plume agate. 4. The final submission is a Mexican Coconut Thunderegg that really surprised me when I opened it up. There appears to be (use your imagination here, again) the head of a dinosaur coming out of the mist to nibble on a tree. Do you see it?

Here are several stones I cut up this past week to see what was inside. They all came from the Four Corners area of the U. S. I would describe them as follows: 1. about 6 inches wide; an agate and jasper mix. 2. a dark but translucent chalcedony partially filled with horizontal crack and some yellowish/brownish plume agate is visible there; there are small, mostly horizontal oriented flecks visible throughout the stone that appear to be pyrite. 3. a thunder-egg with lots of bluish agate. 4. I call this New Mexico Brawn since it reminds me of a slice of head cheese. brecciated stone with really blue agate and yellowish jasper. 5. looks like a yellow jasper stone with a distant nebula peeking through the cracks. 6. a lovely agate-after-barite stone.

A couple rocks found over the weekend in northwestern New Mexico. Sorry I didn't scale it, but both are about 3-inches wide. Thought I'd share. Any comments welcome.

One more piece for I.D. I believe it is Youngite. Thank you for any help.

Need help making an ID as to what I’ve found on the beach!
HaidaGwaiiBeachFinds posted a topic in Fossil ID
Hello All, I’m a newbie to this forum, subsequently solving my many fossil and rock mysteries. This one has me stumped. Surely it cannot be a fossil inside? Does that even happen? Also, it’s more defined than any other agate I’ve seen here (Haida Gwaii). Gosh, I sure hope this is an agate (please prove me wrong, if I’m wrong)! Thanks a mil.

Happy new year. This is my first attempt at a post, so try and go easy. I respect the depth and breadth of knowledge in this forum. Thanks for yours in advance. Unfortunately I do not have a proper provenance for this specimen. This peice was purchased at auction with a rock lot, silified chalcedony (agate), and I was surprised at the symmetry and shape. My amateur mind brought me to fossil bivalve. Another specimen from the same lot shows this exact shape and general size, so here I am. What are your thoughts? Thanks again. 125mm x 115mm x 60mm 1216g or 2lb 10oz

Any idea what kind of masks these are? I used a knife and lightly scraped the mask and looked like glass when it broke off but has an agate pattern to it. Any help would be appreciated. Thank you
-
Are these pieces Jasper? If so what kind? The one piece has bandings. It is at least a 6.5 on the mohs scale. A steel tool wont cut into it, but quartz will. I dont know their origin. The first 2 pics are the same piece and the last 3 is one piece. Any help qould be appreciated. Thank you

Any idea what kind of Agate this is? It is light in weight, 6+ mohs and has druzy. I am not exactly sure where from. Thank you

A rock I found a couple weeks ago in a very old mine dump. I'm not sure what it is, but I thought it was cool, maybe someone could help identify it?

I found this agate on a beach in Northern California. It appears to have a flying insect trapped inside of it. Is this even possible? Or is it an illusion? Who would I contact to find out for sure?

Hi. I've been lurking this forum for awhile. It's a great resource although the more I look around the more convinced I am I'll be the forum's most boring, uniformed member. We have a ton of cool rocks and a few minerals here. It never occurred to me there was anything else. Out looking for agates, came across what looks like some petrified wood and a few other things. At the least, I can learn something at the worst discover I know less than I thought and go back to lurking.

The fossil I am posting today does not contain calcium. I does contain agate and my question is could it be a fossil stromatoporoid or stromatolite or something else?
