  1. Sandstone fossil

    Found in Tuscarawas county, Ohio, USA. I found along a shallow stream bed that cuts deeply through a rocky gorge. Nearby is a large fossilized tree branch and I have found other Fossil there as well. The material is sandstone and I noticed it's starting to deteriorate. The size of the overall specimen is 152 mm in length.
  2. fossil found

    I found this fossil on my property at top of Laurelas Grade in Hidden Hills off Carmel Valley Rd. state of Calif. It appears to be some kind of fish. Can anyone give any more information on what this could be? Entire size of rock is approx 6" wide. I have found lots of mollusk type fossils but never a fish. thanks kathleen
  3. Shell?

    Found this interesting shell today. Seems to be sandstone. Thought it was a walnut shell at first. Can anyone ID?
  4. I found a few of these fossils the other day and cant figure out what it is. Let me know your thoughts. The triangle is flat and you can see corners poking out when looked at from different angles.
  5. Please tell me those are fish!!! (One of my dream find fossils)Found this near downtown Lockhart believe it or not, I’m a little protective over the spot cuz I COULD get super specific on this one and it’s not very off the beaten path ...lol
  6. Just wanted to share the newest addition to my collection. An anchisauripus dinosaur track fossil, collected legally in Massachusetts.
  7. Insect Plant Fish or ...?

    Greetings, everyone. I spent the other day on the east side of Ventura County breaking open sedimentary rocks. I'm not experienced enough with that sort of material to positively ID it but I think it was siltstone. There was a leaf and something else on both sides of one of the rocks. I've been having a hard time figuring out what the "something else" is. It measures about 35 by 14 millimeters. I took a few pictures of both sides under different lighting conditions to help bring out some of the finer details. It comes from the Modelo Formation (Miocene). Thanks ahead of time for any help in figuring out what it is. Here are pictures of the first side: Some pictures of the second side:
  8. Some maritime slab?

    I found this sandstone slab on our property in south west Colorado, near Placerville, and was struck by the spider like creature especially. There also seems to be a mollusk nearby this creature. But its legs would have been so fragile, hard to imagine how it could be a fossil. But it doesn't seem like just a random shape to me. Any thoughts? I had to reduce the pictures quite a bit to fit size requirements here.
  9. I need help identifying.

    Hi I am needing help with identifying my fossil that I have found in Uneeda, which is located in Boone County West Virginia. This is my first try at this so be patient with me please. I've just took an interest in fossils about six months ago . Please help. Thanks!!!!
  10. Found these imprints in the island of Rhodes (Greece). The age of the cediment according to geological maps of the area is upper Pliocene to lower Pleistocene. The units on the scale are cm. I wonder if my assumptions about pine cones are correct (even considered cycad cones) having read about pine cone specimens being found on the island. Would be really happy if someone could pinpoint the species from the shape of indentations - in the first image which is the most detailed there appears to be a small hole in the center of what I suppose are the cone scales. This can also be seen in the second image, though the structure is in worse shape probably due to being exposed for a long time.
  11. This is a really interesting article on imaging techniques used on concretions: https://www.palaeontologyonline.com/articles/2013/patterns-in-palaeontology-exceptional-preservation-of-fossils-in-concretions/
  12. The Fossil/Geode

    This round concretion was given to me. It was found in Garland Texas in some woods. I have tried to ID the type of starfish but it split when I cracked open the concretion. There looks to be parts of more than one here as there are too many legs for one. I'm thinking the lighter spot of crystals is one that didn't form properly or the crystals destroyed the body. Also there is a tiny hole that looks like that was how the minerals replaced the bodies after they died. Well all 3 are in now thanks to Kane. The 3rd one is lower down. Thank you.
  13. I set my 8 year old to work with a rubber mallet and old screwdriver on a landscape boulder in a SE Seattle neighborhood where the bedrock is the Blakeley formation, and where the homeowner was pretty sure their boulders were local bedrock. This was his favorite find, I said it looks like a bit of leaf/seed pod/wood to me. Anyone have thoughts about what it is? It measures almost exactly 1.0 cm x 0.5 cm.
  14. The Twig

    This piece was picked up by the road side infront of my house. Age unknown quary unknown. Some bits of quartz crystals.I'm thinking this is maybe a cast as the stem stands out the leaves do a little. Thank you for any help in identifying this twig.;)y
  15. For those interested in Ediacaran fossils, you may have seen a lot of supposed medusoids coming out of sandstones/quartzites in Namibia. They are usually labeled as unidentified medusoids, but sometimes as the enigmatic genus Namacalathus to command a higher price. At first glance, some specimens do bear resemblance to a top-down cross section of Namacalathus (such as the specimen below), however note that Namacalathus are preserved as calcite skeletons, not as molds in sandstone. A thread discussing these was posted several years ago, without a definitive conclusion. As far as I can find, there have been no published articles on these so called fossils, and perhaps rightly so. After a recent trip to the Field Museum, I am fairly confident that all of these specimens are simply the result of weathering in sandstone. Here is the specimen at the Field Museum that piqued my interest. A quick scan of our favorite auction site will reveal a number of nearly identical specimens listed as medusoid fossils. These holes are likely what are known as tafoni, defined by Wikipedia as "small (less than 1 cm (0.39 in)) to large (greater than 1 meter (3.3 ft)) cave-like features that develop in either natural or manmade, vertical to steeply sloping, exposures of granular rock (i.e., granite, sandstone) with smooth concave walls, and often round rims and openings." They have various methods of formation, but the more "Namacalathus"-looking specimens look (at least to me) to be the result of iron nodules rusting out. They may also be several tafoni that overlapped. Here is an image of tafoni in sandstone from Namibia. (image credit Wikipedia) Regardless of the exact process of formation, I am confident in saying that these are not fossils. There are plenty of other Ediacaran fossils out there for purchase, and given the high price tag these pseudofossils seem to command, I hope this post helps collectors avoid wasting money.
  16. Yet Another Phytosaur Prep

    Here’s another phytosaur I’m starting work on. This one is missing some pieces and we are hopeful the collector can find more this spring. Until then, I have some work cut out for me. It may not look like much now but there appears to be a fully inflated skull under all that sandstone! I’ve already found where some of the random pieces in the trays did and have begun gluing and consolidating. I can see the occipital poking out of the back of the block as well! Finally, a phytosaur that is more prep than puzzle. There are fresh breaks on the maxillae where more should fit. for those bits showing up in a few months.
  17. partial track?....

    from Brazos River west of Houston Texas in a sandstone cast? I am not holding my breath on this one could this be a partial track?
  18. Creek bed fossil

    I found this fossil a few weeks ago. It was in a creek bed that flows during the wet season but has pools in the dry. I know the creek has sandstone, but it also looks like it has limestone and possibly slate. There is also a lot of rocks containing rust. This fossil appears to be stained with it. I am located in Western Kentucky near Hopkinsville. One side looks like it is ribs. The other side is smooth and one part is unusually round. There are pockets that appear to be filled with sediment that has solidified into rock. I've added pictures from all sides and others with measurements. I will add them as replies since the files are too large. I wish I had more, but this is all I have.
  19. Fossil or mineral

    Cheboygan Michigan they look like brains, I find them from baseball to basketball sizes. I broke one up with a sledge hammer, the center gets more dense. The out side seems to house shells?
  20. I found what appears to be a small sandstone on a Tampa Bay beach in Florida. It's about 1 inch by 1 1/4 inch. After looking at it under magnification I saw unusual vein-like strands on these raised tanner bumps on both sides. What is it? Is it a fossil? Thanks Guys! Front view angles
  21. Please help to identify these brachiopods

    Dear Guys, I recently found three very interesting remains- two inarticulate brachiopods and shark like scale in sandstone erratic. Judging by brachiopod fossils I think they belong to paterinids and then this erratic is probably Cambrian in age! One inarticulate brachiopod is 6 mm and another is 3 mm diameter. Shark like scale (maybe the oldest in the world) is 2 mm length and has fragment of root in one side visible. Please help to identify these brachiopods to know the exact age. Any help will be very appreciated! Best Regards Domas
  22. East Texas fossil

    Hello: I found at an East Texas construction site. It appears to be in sandstone. i can see a rib cage and forearm. Any comments are appreciated.
  23. While out before a snowstorm hit the area I was in search of fossils in different areas back in a deep canyon. I found this on a slope for an area known for Silurian/Devonian formations. The Devonian (Sly Gap) is known for sandstone which this specimen is in. Above that it is Mississippian with no such sandstone that I am aware of. I'm gathering some samples to begin learning fossil prep. As this is sandstone, I recall from college using DMSO to loosen sandstone matrix...so it was going to be a sandstone experiment versus the limestone specimens I've got lined up for when my vibro engraver shows up. Anyway, enough babble....any ideas? Length is 2" on the dot.
  24. Found in lake macquarie area. Fossil?

    Found this in the lake macquarie area. I know its a long shot but is this a fossil or just a concretion or something else geological? P.s. just ask for more pics. I can only upload one due to limitations.
