  1. I finally made it back to one of the most beautiful places to look for one of my favorite fossils - Agatized Coral from the Tampa Bay area. I only had one evening and one morning to search and these are some of the smaller pieces that I have. I brought back about 50 pounds of beautiful corals- most of which I need to cut. Can't wait to see what is inside! If any of you have suggestions for cutting it properly I would love to hear your methods. We had a hammer with us but it became clear we were just shredding the coral. I am thinking of using a wet saw to get some clean cuts. If you are not

    Stromatoporoid or Stromatolite?

    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
  3. Hello! First, does anyone know what the mineral composition of most keich fossils is? The common darkly colored ones? Or does it vary a great deal? I have some idea what to look for in the “normal” dark keich fossils, but this one appears to be composed of mostly quartz…? Or is it something else? This seems challenging to fake and the photos look convincing to me, but I have no experience in comparing these white keich specimens. Is this likely to be real?

    Unknown Fossil?

    Hello everyone I am new here and will soon update my profile but was too interested in finding out the ID of this interesting looking formation. I am located in Lincoln County Missouri where this particular specimen was found I'm not quite sure what I'm looking at I have ideas but would like some expert input as I am new to this, this being a childhood fantasy of mine finding fossils paleontology archeology and geology lol. Any help or points in the right direction would be much appreciated thank you so much for allowing me to join this platform.

    Is this petrified wood?

    I found these in Washington County Maryland (live in Central PA) while staying at an Airbnb. They were lying in and around a small creek. I've never seen anything like these before. I kept thinking they were peices of wood but was surprised to find them to be rocks when I picked them up. I also found this large peice of quartz? I have no idea so what do you all think?

    Quartz on fossil bone?

    This weekend as I was out rockhounding for quartz crystals I found this interesting piece. It looks very much like bone to me. Any insight or information would be appreciated. I will add more pics in the comment section. Thank you!
  8. Found in Dahlonega, Georgia. Original origin (if different) unknown. Before I realized it was a fossil, I had aggressively scrubbed the stone with a denture brush in hopes of cleaning off the deep dirt stains. It worked, but I'm not sure if it damaged it at all. It doesn't look noticeably damaged, if it is, but I figured I'd bring it up. This rock is *most likely?* limestone & quartz but I'm not terribly confident in that answer. Any help GREATLY appreciated!! The fossil appears to be a mix of star shaped and column shaped indents, with what appear to be shells as well. There m

    Strange find

    Was wondering what this could be. Unfortunately my kids broke it and I lost the piece that looks like a fossilized oyster or muscle stuck to it I've cleaned it in iron out as I am a collector of minerals but have never found anything like this. It was extremely slimy and stunk when I found it. I picked it up because along bottom has these tiny baby crystals. the copper rusty areas is fragile but has peculiar shapes. Somebody told me it could possibly be a fossilized she'll on coral rock but I'm new to this thank you in advance for any information
  10. I've looked at a lot of sediment now and I just found this. It is a perfect sphere and semi-clear. Hard but perfectly round. Don't think it's a microfossil, but anyone have a guess as to what it is? It was inside a 3 x 6" piece of the formation. Image about 4-500X. Object cannot be seen with naked eye.

    Help ID this????

    Hello, I was gifted this fossil. All I know is that it was found in Tennessee. I believe it is a coral fossil but because of the 'stems' I can't find anything that matches it online. I know fossils cant be valued for price on here but if this is rare and I should contact someone about having it I would like to know. It is in limestone with quartz sparkles in the 'coral' pieces. Thanks so much!
  12. I showed some of this material to a geologist and licensed gemologist to verify what it is, and he said most is agate in some form, and that a lot is petrified wood. I didn't know we had petrified wood up here. The longitudinal grain seems to be clearly defined, and gives a nice striped pattern. The cross-section cuts give sort of a cloud agate appearance. The large "logs" are in the softer stages. They are composed of powdered phyllite mixed in with sand and mica. The mohs hardness is about 3.5. The teal blue striped material in the video is an e

    Geodized fossils?

    I'm a newbie to The Fossil Forum. I hike in the hilly areas of south-central Indiana (mainly Morgan, Monroe & Brown counties) whenever I get a chance and many times I end up walking the rocky creek beds looking for fossils & unusual rocks. These creeks are rich in geodes and there is a lot of shale & limestone. I believe that some of the unusual finds are geodized fossils. I have several that I'd like to share with the forum to get opinions from the experts. Attaching multiple photos (15 total: 3 groups of 5) of 4 different specimens with the first five photos showing a pair w
  14. Hello. I offer for trade fragments of petrified wood of the Carboniferous period with crystals of smoky quartz. Some samples are in the photographs (I did not upload all the samples I have, since there are quite a few of them - of different sizes and qualities, as well as the sizes of the crystals themselves. I think we can agree on what specifically interests you - I have no doubt that I will find the sample you need). The origin of this wood is Ukraine, its age is Carbon. I'm interested in marine reptiles and petrified wood. Thank you. Have a nice day
  15. Hello. I want to show you some examples from my collection. This is a Carboniferous wood. The preservation is not the best, but for me these samples are interesting for the presence of crystals of smoky and ordinary quartz on them. A sliver that has broken off from a larger fragment. There is more quartz than wood Perhaps a stem or stump - it is almost round in cross section. And thickly overgrown with crystals. Large flattened fragment; perhaps the first sliver was from it.

    Trying to Identify Marks on Geode

    I found what I think is a geode in a small stream here in Vigo County, Indiana. Brought it home and discovered all these unusual circular patterns along the narrower edges. Looks like urchin but I have not been able to find a similar type online. It does not feel hollow. Has anyone seen a similar surface patter on another specimen?

    Cool find today

    Looking to see if anyone can tell me what I found. Big 1 looks to be solid quartz. The 2 small ones are as big as a finger.
  19. Hi guys! I am looking for new areas to hunt for rocks and fossils around the KC area. I have been to the Blue river, Kansas river, Cedar creek, Tuttle creek, Perry Lake, Mill creek, and abandoned quarry areas. Anyone have any general locations of where I can find some stuff? I am an avid hunter for all sorts of fossils and rocks (rockhounding is my favorite past time)! I've had the most luck at the Kansas river and Perry lake. Some of my finds include cow skulls, cone coral, shells, agates, vertebrae, and a bunch of druzy quartz geodes and chalcedony. I ha

    Quartz Snail (Gastropod) Fossil?

    It's been a while since I have been on here. Life got in the way of me looking for rocks and fossils. The property that I have access to hunt in has several seasonal creeks on it. This was found in a dry creek bed. I didn't think a lot about it as these type of "snail" fossils are the main thing that I find. When looking at it closer at home, I realized that the fossil itself seems to be replaced with quartz? The surface has been worn down by weathering and by the creek flow during the spring. I am not sure that the images convey the crystal properly, but the clear, crystal structure is
  21. Hi all, is this piece a fossil in quartz? It was found in the Andes region, I don´t have it myself, sorry for the pictures. Thanks a lot for your help!!!

    Potentially Petrified Wood

    Hello all! I am a new member, and this is my first post. Could I please have some help figuring out if these rocks are petrified wood? Most of them were found in a small Pennsylvanian stream. It looks like they are quartz, crystal quartz, but I am no expert. There should be about two pictures of each rock. Thanks for your help, and I have more pictures of different rocks if needed.
  24. Here I am again, with questions on another rock! I can recognize more and more fossils and rocks, but I love finding things I don't recognize. :-) This limestone rock, found in Huntsville, AL, as a portion that has a lot of quartz in it, and a lot of tunnels and crevices. I recognize the crinoid fossils but am not sure about some of the other ones. I have put questions marks on the areas I am wondering about, and asked a question in one image. It also almost looks like there are areas where geods were trying to form, but that may just be due to all of the quartz. Help appreciated!
