  1. Possible mudcrack?

    Found this on a rocky beach in Southern California and have no clue what it could be. Both sides are almost Ying yang like. Let me know if you have any clues!
  2. Hello, here is my experience with my cheap little tile saw purchased 12/22/2020. That´s the setup at the moment: Some modifications and additions: - I rotated the saw by 180°. This is first to reduce spraying into the face. And second it is much easier to "feed" from the back. You also have much more visual control producing an even cut in this way. Electric switch is now at the back right, which is no problem. - Glued two thin plates (2 mm) onto the table, touching the blade. The table has a big gap at one side of the blade to allow tilting of the table. That´s a nuisance, specimens can get easily jammed in this gap during feeding, resulting in very uneven cuts. The line where the two plates (nearly) meet is also a very good visual guide. Cutting height is now 32.5 mm. - Build a hood out of wood and toilet paper bags, not many words needed. - Saw is sitting in an old backing tray. - Cable connection needs to be a little bit lifted with a small rock, otherwise it is bend outside the anti-kink device and is dipping into the water... (faulty design!). - A lamp was already there. Results: - The blade cuts extremely well, the motor is powerful enough. Cutting one of the larger fossils only takes half a minute or so. - It consumes a lot of water, dripping onto the backing tray. No problem, just suck it up with a sponge cloth regularly. Used about 2-3 liter for 8 specimens, refilling at least after every cut! - The motor becomes warm rather quickly, it takes about 250 Watt running idle. It is rated for 600 Watt and 10 minutes short-time duty. I don´t think, it would survive that... So I have to let it cool down regularly, when it becomes very warm to the touch (maybe about 50° C surface temp.?). - The cuts are quite uneven for my taste. This comes from the fact, that the diamond-bearing ring is relatively thick compared to the metal disc carrying the diamond-bearing ring. But that´s the way it is. The better your fine motor skills, the smoother the cut. Mine are not good... - Highest specimen I have cut was 69 mm high. This resulted in a little "knob" in the middle, had no problem to grind it away with the saw blade. - Saw is situated in the basement, have no sink there. This is also a little bit of a nuisance, but that´s again the way it is. Using a bucket instead. - It is potentially dangerous. I have nearly 30 years experience with such kind of saws. I you have none, I strongly recommend personal and practical advice of someone experienced with these kind of machines and work. - Safety googles are a must, of course. - Gloves may be good, but such diamond blades are quite smooth, no real danger for accidental serious injuries by the blade itself. - Ear protection can be worn, but it is not extremely loud and when you are using it only for a few minutes every week or so, it does not matter. - Biggest danger are flying rocks when feeding the saw improperly. But this never occurred to me in 30 years. Just feed it correctly. Here are the results of today´s early morning work, box is 30x20 cm, biggest specimen to the lower left: Feel free to ask anything.

  5. Hunting at McFadden Beach

    I've found a number of fossilized jaws on this beach that I have no clue of the animal they came from. Hopefully someone here will be able to tell me. We also find many bones of probably bison that hasn't fossilized. So here are a few pics -------- This is what the beach looks like.
  6. Hunting at McFadden Beach

    I have hunted McFadden Beach many times. It's located on the Texas coast near the small town of High Island. Most of the it's easy collecting bones, teeth and if very lucky, even a paleo dart point. I can't put names to many of even the bones we find on the beach but my question isn't about the obvious bones, but about many of "something" we have found that has turned into what I believe is iron. Please get your opinions. Were these some kind of animal or plant or just funny looking rocks? First picture is what I'm asking your opinions about. Seems to me they turned into a form of iron. Have people hunting McFadden found anything like this? Then for the group, are this fossils and what are they? The second picture is the fossils most people find that hunt McFadden. Thanks everyone for your time.
  7. rocks with holes

    are these natural , found a few of these
  8. new rocks

    found the first two yesterday , the second pair have a lot of shiny crystal like stuff in them
  9. I first learned about this forum today, and I was able to identify fossils that I had been curious about for a while. I was very happy. I am recently interested in fossils, prehistoric creatures and dinosaurs. I will continue to receive help, and I will do my best to provide a lot of help. There are a lot of stones I picked up by the river in my house, but some of them have holes. How can you distinguish between 'trace fossils' and 'just erosion' holes? (Clockwise 1-2-3-4; stone 1 was washed with water before taking the picture.) (1) Can you guess that these holes or curves are trace fossils? (2) I wonder if this hole is characteristic of a particular fossil. Or could it be a coral or a sponge? Or is it just like basalt? (3) I am not familiar with anatomy, but I am wondering if this is a bone. What do you think? (4) As with the others, there are some holes and'traces' similar. I wonder if this can be viewed as a fossil. thank you. It would be great if you could leave a simple comment.
  10. My wife dragged me away from Big Brook this weekend for a trip to Cape Cod. Beautiful but non-fossilious Cape Cod. So what’s a fossil collector to do? Well if you’re on the Cape you walk the beaches looking for modern shark teeth and perhaps some cool bone. No shark teeth and the closest I came was likely modern bovine teeth (although I suspect it’s been a long while since cows were grazing out there). In a pinch, rocks and shells would have to do and I had a ball nonetheless. I did find some horseshoe crab and sea bird skeletons but so far she who must be obeyed won’t let me bring them inside so they’re still in the trunk. BTW does anyone have any idea to strip the mussel shells down to the mother of pearl level?
  11. Are any of these fossils?

    I'll preface this with that fact that this was my first time fossil hunting so these are probably just be random rocks haha. These were all found at Agate Beach, CA, where some petrified bone and shells are known to be found. Pencil is for scale
  12. This is a completely new area of interest for me, but I find scanning for microfossils addictive. I got some vinegar and plan on processing some beach rocks (East Central Florida) that I picked up because I could see easily see some small fossils on the surface and assumed there would also be micro fossils inside. I crushed a few small samples, which did reveal more microfossils. Mostly what I could identify are broken bits of bones, but I'm sure there is much more that I'm missing. There is one object I found very interesting and beautiful, however I don't know what it is. I would like to know what you think the first object might be. That object is still attached to the matrix. The other object I found in the same sample. Both were revealed after breaking the sample. The first item is about 1/8th inch long but very narrow, and from some angles appears to be a hollow tube. The next object appears to be bone and is only about 2.5 mm wide and long. Thanks.
  13. Hey everyone. I thought I'd share some of the things I found on my last fossil hunt. So.. Many.. Fossils! One might even say that there were a plethora of fossils. If I could, I would've taken them all with me, but sadly my backpack can only carry so many rocks. I was literally examining each rock I had, trying to decide which to carry back and which to leave behind and how many I could fit in my pants pockets before they started to fall down. Eventually I decided to just stop looking for fossils and hike back to the jeep. This lasted all of 3 seconds before I found another a beautiful byrozoan and was trying to figure out how to fit it in my pack. The byrozoan and the sponge below are my favorites since i don't see many of them and the brachipod in the matrix just looks cool. lol Its fascinating to look at these fossils and think about how Arizona used to be completely underwater long, long ago.
  14. A very simple website (mostly pdf-documents) about my fossil hunting trips and some other stuff: Die Steirische Geo-Seite All in German... Franz Bernhard
  15. Yesterday (Saturday, Aug. 22nd), I went fossil hunting in Ellsworth County, Kansas again for elusive Dakota Sandstone leaves and unfortunately it's mostly a bust, just like the previous trip. Despite that, I enjoyed the scenery and found some odd rocks and few fossils from new sites. A new site produced a few small plates containing woody and plant material fragments. I decided not to keep them. Closer views... Remember that interesting sandstone from the previous trip? I regretted for not taking it home so I took another opportunity and revisited the old site to get that rock! The back of this rock is quite smooth and flat, I think it would be great to have it hang up on the wall, but I'm actually not sure how I will display it. Looking at it is like reading a 3D map! It's the only object I brought home from this trip. It's peaceful out there and the views of the Smoky Hills never gets old. ...continued on the next post.
  16. Is this real or man made

    Is this real or man made? Unsure what it is
  17. Sharks Teeth or Rocks?

    Hi Everyone! I'm new here but was hoping for some help. My daughter and I were hunting for sea glass yesterday along the coastline in Jamestown, RI (there is a small, hidden location that has worn down glass, pottery, shells and stones) and I found a few treasures that look like they could be shark teeth but I'm not convinced. In your opinion are these worn down fossils or simply rocks that got my hopes up??? Any input would be greatly appreciated!
  18. Me and my fiance headed into Wauchula this afternoon to try to find some good gravel spots at the behest of @Shellseeker and his helpful advice given to me on my last post. I have been to the Peace a total of 4 times, all within the span of a month or two because these water conditions are just way too good to pass up. Every time I come back to the river I have a new game plan and every time I actually get TO the river the plan goes out the window. Today's adventure was no different. We pulled up to Wauchula Riverside Park (Crews Park?) and were pleasantly surprised with the condition of the park. I had read about some sketchy things happening in that area and while we were unloading our gear a police cruiser circled the lot twice, it made me feel safe about leaving my vehicle. The park seemed newly renovated so I was assuming these past cases of break ins and theft occurred before then. We walked over to the boat ramp and prepared to search for a gravel bed north of the park; that is until we came across a friendly kayaker and her son. She noted that down the river a little was an island that her fossil hunting friends liked to dig at but had to swim to get to it in higher water season since they didn't use kayaks. We were not prepared to swim but the thought of a glorious "fossil island" that my fiance can set her chair up on and watch me sift gravel for 8 hours was just too enticing and we abandoned our upriver plans and decided to head down towards the bends. We found a small sandy trail to take us as far as we could on dry land before we had to make any attempts into the river, there were many downed trees and root systems that would make walking the dry area pretty difficult. This trail lead us into some of the highest and thickest grass I have walked in. I felt like I was going to be attacked by a pokemon... or a snake... but we were lucky and did not have any issues. I think this is a trail in the Peace River Park. Anyhow, we found a nice spot to cross the deep part of the river and found ourselves on the opposite side of the bank, it only came up to our thighs but there was zero visibility in the water. Then suddenly, a dad and his kids make an appearance with their fishing poles... After a quick chat we learned he was heading to a similar spot around the bend to fish a hole... You should have seen the look my fiance gave me. How in the world would we be able to dig for fossils in the same area that this guy is fishing in deep holes?! WHERE IS FOSSIL ISLAND? My hopes were dashed, my fiance wanted to go back to gardner, and there was a huge downed tree in the middle of the river with no gravel in sight. TFF what would you have done?! I continued on. Luckily it paid off. We hopped up on the legal side of the bank and walked 20 feet further to the end of the first bend. It was there! Sticking out of the middle of the river like a huge zit ready to burst with meg teeth WE FOUND FOSSIL ISLAND! We hopped back into the river and crossed the deepest part to get to fossil island, it was about knee deep and the entire bottom sounded crunchy which my trusty fence post confirmed to be a pretty significant gravel layer. Fossil island was pocketed with holes from other diggers but I was more interested in the deepest part off the side of fossil island. I figured when the water level is up this deepest spot will get un-diggably high but since it is so low right now I can get 2 to 3 feet into the gravel before the water started getting too deep for my shovel. At this point the JoshRockz excavation project was in full swing. I was digging in this layer and in the first couple sifts we were already finding larger than our usual size teeth. We got about a foot down before my fiance decided to go surface collect and I was getting alot of clams in my shovel loads but not alot of teeth, I widened out my hole and noticed I was pulling out chunks of matrix as shown in IMG 6228. I will be displaying this piece, I have not encountered the hard rock matrix; I have only really encountered the thick clay in the deep areas of Gardner and I imagine this is how it weathers out of the walls of the peace. Around these pieces of matrix I started to pull up many megaladon frags and hemis along with smaller teeth of other variety and quality. These are the largest teeth we have found thus far and I am so happy with our first dig in this location! The only downside was that this area in general has alot of broken glass that fortunately did not harm me but definitely made me reconsider not wearing gloves in the river. I also pulled up about 15-20 iron nails that were at times in a pretty dangerous condition and large. Tetanus city. This was 2-3 feet down into the gravel I was pulling these nails out so I am a little intrigued as to where they came from. All in all I will be returning to Wauchula in the future and I cant thank Jack enough for his advice. Oh, Turns out the largest hemi (also) the largest intact tooth that we found (second left in 6226) was surface collected right on the top of fossil island by my fiance. Strange are the ways of the peace river... ps I am going to get a kayak because all of this could have been avoided and we could have been there in 5 minutes if we had one.
  19. I collected some weird fossil rocks today from Lake Michigan in Wisconsin, what are they?
  20. portion of my collection

    a small part of my collection. I am into rocks, fossils, shark teeth, shells and more! Love hunting for such!! Deb
  21. Fossils or not

    washed up on Isle of Palms beach outside Charleston SC Upper left one has me dumbfounded. Would love to know if they are bones, what animal are they from
  22. Greetings kind people, I'm so sorry if this is such a noob question. But I've searched and searched but I couldn't find answers to these on internet. (kindly correct me because I feel I maybe wrong): Smithsonian website said licking dinosaur fossil helps in identifying between a rock or a fossil... But isn't fossil a rock in itself? Fossils are made because minerals get replaced and it's not possible for bone to remain in its original state for millions of years. So, it's not the original material anymore.. so licking a fossil should equal to licking a rock? In that case, licking should not work?
  23. River Drava fossil ID

    Hello fellow FF enthusiasts! So first of all, please bear with me, I basically just got into fossil hunting and my eye is not as keen yet, but I managed to have a nice hour / two outside and found a couple of different small finds, things buried deep within bigger sedimentary rocks, located just next to the river (some inside). I'm going to give some short info regarding where they were found and the geological age of the region I'm searching in. Location: River rocky beach (river Drava / Drave, southern EU). Geological era: Neogene / Neogene (-Quaternary) I will post some pictures, which are accompanied by a ruler in EU measurment (centimeters - cm). Like I said I'm no expert, but I will try to give some opinion on the pictures. If you are familiar with anything found here let me know, I'll be happy of just about any new knowledge and information that will be obtained Pic. #1: The way I see it, it looks like a 'Brachiopod' shell, but I'm not sure if it actually fits into the time zone. I would more likely say it is a 'Barnacle or a Theostraca' found in Pleistocene. Pic. #2: (three pictures of it total): I found this 'rock' already submerged in the water and by the looks of it it just might be a regular rock, but it's shape caught my attenion since it is very smooth underneath and seperated by, what it looks like, a channel of some sort? It's length is approximately 3 cm (1.1811 inch) long. Again, any info on this would be great! Pic. #3: No idea on this one. Maybe a part of a gastropod, like an inprint of the shell itself? Lenght 8mm (0.314961 inch). Pic. #4: Preety sure it is a gastropod of a sort, looks like the whole shell is solidly preserved. Underneath is also a small part, most likely a part of the upper and bigger shell. I would say it looks like a 'Neptunea contraria', but I can't say if it is actually from the Neogene period or something more recent? I would also like to ask for any tips how to remove it or at least not brake it when attempting to make the entire rock smaller. Also is it necessary to apply any substances to such things or will it survive like this, stored somwhere dry? That would be that. Like I said, it's not much but I was very happy to find anything at all. Thank you in advance for any answers and the time you will take to read the post!
  24. I was hiking with the wife looking for an old abandoned Train tunnel built in 1899. [found it.] I saw some rocks that caught my eye and picked them up. One looks like Ar Quartz and one looks like it could be crinoid's but not sure. Any help appreciated.
