  1. Found this near the Snake River in Eastern Oregon, just wondering what kind of crystals they are, or are they a gemstone? What is the difference between gemstone and crystal formations. Thank you for your time!
  2. I stumbled across this amazing place, but I have no idea what I am looking at. Just looking for a little knowledge because I can't afford to attend a college, as I am too busy collecting rocks!
  3. I found it in Southern Ontario next to a creek. I know it's a straight shelled cephalopod but anyone know the green mineral inside.

    Crystalline Cephalopod

    Snow storm overnight allowed me some time to expose this cephalopod in it's Galena/Ordovician matrix. Only the crystals were exposed so I was happy with what was hidden beneath the rock. As I have said many times in the past, I love the combination of fossil and crystal.
  5. Hey, I need some help in identifying this specimen. I found it by a tree I was digging out in my yard a few months back, and I don't know what it is. I took it to a gem and rock store once, and the guy there put some liquid on it to test it, but he said it wasn't coming back as anything, and he couldn't tell me what it was. Aany ideas would be much appreciated. Thank you .
  6. We live in Southwest Michigan. We have a large barn filled with miscellaneous things including many large rocks collected over the years. We have no idea where this one might be from- possibly belonged to our Aunt from Chicago who spent time in Australia, Hawaii and Florida (sorry I know that doesn't help I'm just trying to give details). I really love this rock, and would appreciate any thoughts! I have the utmost respect for paleontology, and zero experience in this field unfortunately, so I do not know how to look at this with educated eyes. Knowing this, forgive me as I describe what I see: The rock is very heavy (20 lbs) and appears to have metal or iron embedded in certain spot areas. In those particular areas (of iron) it is shiny, slippery and smooth. All other areas are rough, rock like. There are a few tiny bright green flecks that look like gemstone, as well as little crystal flecks at the flat end where it appears to have been broken off. Opposite that end, at the more narrow end, there is a series of something that looks like it could have been alive- a tiny spine or something? A long bug? Additionally there is a mark in the center that stands out almost heart shaped that is interesting in appearance as well. I have it positioned on a round placemat that is 15 inches across. It is so heavy that if I pull the placemat across the granite, it feels like it's cutting or scraping the granite surface. Thanks in advance, looking forward to your comments!
  7. This is a boulder opal from Australia. The dimensions in mm are 8 x 6 x 2. The pictures are taken under a microscope, and the resolution is low. in the images #1 and 3 you also could see the background, which IMO is also unusual. I wonder if the inclusion is organic, and if not, what mineral could it be? Thanks!

    Help ID round hollow rock

    Not sure what this can be any advice welcome found in south eastern kentucky, was not split in half after about 6 months looked at it and it had a large crack split it and found kind of hollow with tiny white crystals and what looks like dirt, that is the magnetic part the dark brown in the middle … chapstick is for size reference

    Arkansas Crinoid?

    Found these last summer but just getting the energy to find somewhere to ID them. I'm not sure what the crystallized impression is, but I know at the very least that the others are probably crinoids of some kind. Thank y'all, even if nobody can ID at least others can enjoy.
  10. Good Evening, I have this mineral that I purchased at Johnson's Rock Shop in Indian Springs, Texas. There was no information on the piece, but the price was right... The whole piece is approximately 14 cm by 14 cm. The individual crystals are approximately 1 cm across. Could anyone help me identify this? Thanks... Daniel
  11. Hi y’all I just visited an abandoned mine here in Nevada, and found a crystal covered rock, or so I thought. it’s from a local manganese mine and found at the shore of the lake . I 1/4 of this was sticking out of the ground. when I took it home and cleaned it up a bit I noticed weird “sockets” and what looks like either a fossilized fish fin or some sorts. maybe my imagination playing tricks on me . Maybe you can help. I also think I may have found a dinosaur egg that I first thought was a geode. IMG_6828.MOV

    Hello from Oceanside CA

    Hello, Call me Cat. New to all this but I love rocks, geodes and fossils!
  13. This oddly colored crystal druzy was found in August of 2022 on a iron tailings hill outside of hibbing, MN. I've hiked many of these dump spots for high quality quarts, this particular hill didn't seem to bear any though. Aside from the subject in the photos, there was nothing else that caught my eye about the location. If anyone has any ideas about its identity, I would greatly appreciate it! Happy hunting!

  14. Last weekend our club got together in a quarry. The leader said it was primarily for mineral collection and explained few if any fossils are found in this Devonian material. He was absolutely correct and I was equally disappointed! Our club hunts typically produce both minerals and fossils. But not this quarry. Here is what I scraped up: Not too impressive for 8 hours of exploration. I did manage to also find a trilobite cephalon that I donated to a member that found a pygidium. Anyways, the minerals, unlike the fossils were plentiful, varied , and beautiful. I stumbled upon one vug that measured close to 24 inches across and was on the lower corner of a 2 ton boulder, covered with 1-2 inch crystals!!. The belt of my rock saw gave out after about 30 minutes of rock removal forcing me to leave it behind. Our leader is going to see if the quarry can pull this beast to the side and he will try to extract this wonderful specimen. When I returned home and began chipping matrix away from some of the vugs, a special treat was in store for me. A black spot showed up on the exposed layer of a specimen as I worked on it. After I exposed more of the dark area, it turns out, this quarry did indeed have an exceptional Devonian fossil. I am not sure of the identity of this tooth. So these images will also show up in "Fossil ID"
  15. I have found, what I believe to be a fossilised vertebra, and would like any advice on what species it could be and how old it may be. The item was found along a riverbank. It has a surprising weight for it's size - I can record the exact weight with electronic scales within the next 24 hours. The object appears to be of white bone with a red/iron marrow present through the centre. There are crystals in the recesses which sparkle when the light hits it and when it is wet. The top and bottom of the item are very smooth. The specimen has been washed with warm water and a toothbrush. It ts extremely tactile, a pleasure to hold! I didn't want to put it down until I decided to keep it in a resealable plastic bag. I have some pictures which I will enclose (the sun was setting and so there are long shadows cast - magnify the images for better clarity) - I am a novice photographer! I also have a short video which could be sent via WhatsApp. I have contacted my local museum and left a voice message - the museum closed for refurbishment for 2 years about a week ago!
  16. This rock is full of crystals that catch the light. It could've been a seashell that left this imprint, but I have to wonder if there is more than meets the eye. Any ideas? Please have a look..
  17. This rock is shaped like an oyster and the ring around it's mid section glitters with light.

    Is this an egg?

    Hi everyone, First, thank you very much for your help in identifying fossils! I just discovered this resource, and am grateful it exists. I found this unknown piece in a collections storage closet in the museum I work for. It was mixed in with other fossils and geology samples. Unfortunately, it was unlabeled, and so I do not know where or even when it was found. Again, thank you for your help, and I apologize for not having more information about the piece. If you need any other pictures, I would be happy to take them.
  19. I am visiting my wife’s brother and he found these in the desert in egypt many years ago. He was told they are fossilized camel dung. Anyone out there know what they are for reals? They are very dense. I hope the pix are ok. This is my first ever post from my phone. Adult human hand for scale.
  20. Found near our home recently. Was covered in grime and mud but a bath sorted it out. Quite a percentage of iron in the ground here. Weighs just over 4 kilos.
  21. TL;DR.... is there a good way to separate attached calcite crystals to minimize (or repair) damage to the perfect look? =================== In Central Pennsylvania (USA) one part of the Keyser Formation has calcite-filled vugs. I recently got interested in trying to expose more of the crystals for display. A lot of the pieces in the float are pretty much "closed up" in their limestone tortilla wrap like this.... The other side looked kind of like this too, until I started pecking at it with a knife and micro-pick, to gradually break off the "crust" to see the inside. Some small crystals were lost, of course. If there was an air gap, then this works fine, though slow and messy. But sometimes a crystal I want to keep in the finished piece is attached to what I am removing. Then there are blemishes, like the bit of white "break" at the tip of the larger crystal in the middle of the pic below. Is there a good way to separate these crystals without doing that? Or is there a good way to hide or repair the look later? Thanks
  22. Found this along a long abandoned RR outside Altoona PA (USA). A rather plain side was showing and I whacked it with my hammer expecting to shatter a large piece of glass slag. I was rewarded with a metallic ring and tingling hand. Its very dense, magnetic, and has three obvious planes (cleavage? Crystal growth?) Some of the flat surfaces shine black-iridescent, others gold-iridescent. It's too hard to scratch with my finger nail (I haven't done further Mohs testing yet). Its not hematite because the streak is dark grey to black. I'm pretty sure the rock fell off a rail car, but this track hasn't been used since probably 1900. The USGS Atlas 86 (1989) lists iron lead and zinc as historically worked ores in the area; but the descriptions don't sound like this. But then its along the RR so could be from far away. Is there a site like this but for minerals?

    Is this a shellfish fossil?

    I think I’ve posted before in the wrong area…hoping this is reaching y’all: found this in Bexar County San Antonio, Texas in my neighborhood which is new construction. In this area I’ve found a lot of petrified trees and other types of possible water creatures. I’ll attach those pics since I may have posted them in the wrong discussion area.. this looks like a shell of some sort and has beautiful little crystals in the ‘valleys’ of the sunburst pattern..
