  1. Small ammonoid from Jordan

    I found this on the surface of the land next to my house. when you expose it to the sun, you can see crystals reflecting light
  2. Egg Mold from Jordan

    hello, I found this egg mold close to my house, there were an excavation, i found it in the dirt they bulldozed away. (it wasn't broken when i first found it, it fell by mistake). from the other side it's just a normal orange-ish sedimentary stone(i don't have enough media MBs left). And, I see these orange lines in the bottom of the stone too often on other stones i want to know what they are. thank you.
  3. Florida Marine Fossil (Chiton)?

    I found this grayish sedimentary rock on the shore in Dunedin Florida, USA. It has a white grooved oval imprint on it like some critter fossilized on it. Could it be a Chiton? (Ruler is in inches) Thanks All.
  4. Asymmetrical Ripple Marks

    From the album FreeRuin's Finds

    Marks left by the movement of a river or stream in the early Jurassic. Hartford Basin Portland Formation Massachusetts
  5. Mud Cracks Imprint

    From the album FreeRuin's Finds

    Multiple cracks made from the drying of mud, probably near a seasonal body of water Hartford Basin Portland Formation Massachusetts
  6. Mud Crack Imprint

    From the album FreeRuin's Finds

    A mud crack preserved in the shale, I determined it not to be an ichnofossil due to more that turned up in the rock. Hartford Basin Portland Formation Massachusetts
  7. Large fossil(s) ID. Port Angeles shale

    Hi there! First time poster, so I apologize if I'm lacking information. Also, my phone died on my way to the location, so I couldn't take pictures of the area I found them in. I tried to doodle a picture, but I'm no artist. Today I decided to check out a beach I had heard about near Port Angeles on the Olympic Peninsula of Washington State. . On this beach, there is a section of mudstone/sandstone about 60 feet tall and 100 feet long. At the base of the slope was a boulder(also sanstone/mudstone) about 6 feet tall and 4-5 feet around. It must've recently fallen because it was crumbling more and more just from looking at it. Right in the middle of the clump there was some sort of long, lumpy fossil(thought it was, sounds like it's not ;)). I have no idea what it could be. I've googled "lumpy dinosaurs", "lumpy whale vertebrae", and a few more embarrassing amature terms, all to no avail. If anyone could help me identify these, I would be EXTREMELY grateful! I've definitely caught the fossil/rock hunting bug and am really excited about finding these. If any other pictures/measurements would be helpful, just let me know. The largest piece is about the size of a volleyball. Edit** forgot to add, it was found in either lower tertiary sediment, or quaternary sediments. Sort of on the border of the two according to my map Edit #2** Just did a little more researching on the area, and it is part of the Twin River Formation. "Upper member, massive to thin-bedded mudstone and siltstone. Olive gray to greenish gray mudstone, claystone, and siltstone are poorly indurated and contain thin beds of calcareous claystone and a few thin to very thick beds of massive calcareous sandstone. Spherical, cylindrical, or irregular shaped calcareous concretions common"
  8. geology question

    I was in an agate field in South Dakota just south of Badlands Park. Cretaceous era. I collected a few not-so-special agates and some jasper, and the pictured rock, which I thought was wind polished jasper- but it broke and had what looks to be brachiopods inside. I assume this is sedimentary or metamorphic. What is the relation between the agates in this region and the kind of specimen here? Why are there so many agate fields in this area of S Dak?
  9. Partial Thoracic Skeleton

    There is excavation for a housing development behind our home. On examination of some large excavated limestone boulders, I noticed what appeared to be a cross-section of thoracic (rib cage) of a skeleton. I suspect it is a fossil, being that there is a noticeable pattern within the same layer of sedimentary rock. I've attached a picture, please note the rust colored protrusions within the blue-gray limestone boulder. Thank you for any input on whether my suspicions are reasonable. If so, I intend to contact the construction company as to the location of where the boulder was excavated, and whether they are agreeable to removing it from construction use.
  10. Found these about 3 years ago in a pile of similiar looking fragments that were sitting atop sedimentary rocks. These appeared to have been broken out of one of the top layers. Sounds strange, wish I had pix of the site itself. I thought that they might be bone fragments, my girlfriend (who knows way more than I do) stated that these were likely rocks. The shapes and consistency made me think otherwise. Thanks for any advice.
  11. Georgia Fossil - Dome shaped

    Hi Fossil Forum, I need help in identifying several fossils my friend found in middle Georgia. The area where he found them has been reported to have fossils from the Ordovician Period. They were found in a soft limestone sedimentary rock. The fossils may be in the sand dollar family, but don't appear to have a star shape on top. The dome is somewhat elongated and appears to have fine fibers running from the top of the dome to the bottom edge. Any idea what he found? Thanks, Darren
  12. Rock, Fossil?

    Hi everyone, In another walk near a mountain river in Northern Italy, I found this "suspect" rock. It was very different from the others nearby, not sure it's a fossil though. What do you think? The rocks are dated 65 million years old. Thanks in advance! Luca
  13. Small Trilobite?

    Hi everyone, I was hiking in search of fossils near Fonteno, Beramo in Northern Italy, just by Lake Iseo, when I found this object. Having recently been to the Museum of Natural History of Bergamo, I found out that near Fonteno it was plentiful of fossils, dating back to 400 million years ago, when Lombardy was at the bottom of a sea. The fossil (hope so) is 1 cm across, opaque black, and two of the three lobes seem clearly visible. I used my macro-lens to improve the quality of the details. I hope someone will help me identify it, Thank you all in advance, Luca
