  1. It's just an impression, but I find so few like this I had to keep it. Looked all over for the positive but could not find it. It seems so long and narrow for a Bostrychoceras, or is that just an aspect of the impression? 5 whorls visible.
  2. ID oxfordian ammonites from Podleze, Poland

    Hi all, I am hoping to get some help, identifying some ammonites and a nautiloid (?) from Podleze, Poland. The locality is oxfordian and a famous place where you can find a lot of Perisphinctid ammonites. I am new to this locality and because I do not know polish language I only find a few paper on this locality, but they are only dealing with the Perisphinctes ammonites. Here is the section of the locality, the fossils are found in 2 layers of 10cm thick glauconitic marl. Here are the pieces: I will gladly send bigger or other pictures if needed, but I reached the upload limit. The bigger coin is 23mm in diameter Thank you for any help! Kind regards.
  3. Please help ID my find

    Hi please help me Identify my find, this was found near whitby Yorkshire, it looks similar to my ammonite collection but I never seen one with a closed end before so I'm stump to what it is, thanks Mike
  4. I am collecting heteromorph ammonite and one vendor is offering this ammonite to me. He does not have the id. For me its appearance (i.e. color and shininess) is quite different from what I have collected.
  5. Fossil collection

    Hello fosill lovers! After a long long time dreaming at last im starting my own fossil collection! So far i bought some ammonite and petrified wood,And im wandering what other fossils are a 'collector must have' Sadlly im on a really tight budget,so if someone know a good website to buy some i will be so Thankful
  6. Bizarre fossilized piece

    Hello again- I am doing a favor for a friend who is a "picker," and frequents estate sales. He collects many things, but not really fossils or rocks. He did happen across this very odd rock piece and asked me if I had any idea what it could be. At first I thought Ammonite, but upon further review of better photos he sent I doubt it is. It looks to me like an old piece of machinery that left an impression in material that hardened. I've seen it in person since and it is very strange, definitely rock, and doesn't look to be of natural origin; but then again, many fossils or geological finds can look so similar to something of human origin. So, any idea what the hell this thing is? Sorry, being an estate sale he asked questions, but the people running the sale were not family and had no information at all. He bought it for $2! I would have as well for that price!
  7. Went out today for a few hours and found this sweet looking ammonite imprint, with fish scale bonus!
  8. Ammonite?

    Hi there. I recently found this fossil in Texas. From what I've seen online, it appears to be some type of ammonite. Would anyone be able to confirm that? And any ideas as to what kind of ammonite? Please let me know if I need to add more information or other pics. Thanks!
  9. Which one is this?

    I'm an amateur fossil hunter (stumble across, pick up) and need a pro's help. I've found a bunch of these "ammonites" and I can't find them in books. I'm a bit of a stickler when it comes to classification, and I would like to put a real name to these. This is one of the larger ones I've come across. P.S. Sorry for the lousy quality of the photo
  10. What kind of ammonite

    I found this ammonite at Mappleton yesterday. Only the outside (white bit) was showing so I used my hammer and the sides turned out great. Notice with water how the squiggly lines show up really well on the edge. Thank you
  11. The bad weather gave me time to spend some time classifying. so i spent some time on my albian stuff. Everything has been self collected (surface collected) over the years. Everything is also small, so i chose the screws cases to store them. Everything can be seen on a dedicated galery on TFF : here or in higher resolution on my flickr : here 8 cases... So here we go Ammonites : (3 cases) then crustaceans (2 cases) : Other inverts (2 cases) : And last one : vertebrate remains I hope you enjoy it. that's all for now.
  12. I saw that fossil online today and i have no idea what it can be... It was under the tag of ammonite,can it be fossil wood? The rings remind me Petrified wood but it cleaner then every petrified wood i ever saw,what can it be?
  13. Ammonite ID please

    Hi, out hunting yesterday with not much luck then on my retreat I came across this on the footpath back from the beach at Ravenscar North Yorkshire, strange place to find it with it being high up, the path is in a fault line I believe, this doesn't look like anything I've found before, the nodule it is in is like red sandstone ? Any ideas ? Thanks. No idea why photo went upside down ?? Ha
  14. Prepped by hand outwards in (minor) until I had the centre resdy, thought a few little taps with a small cold chisel would pop the centre up, nope, just chipping away, my ST pen will just bounce of this for sure, any other methods ? Nice sized specimen and hoping to view it in all it's glory.
  15. Help for my thesis

    Hi, I come here because I need some help. I just collected samples for my thesis and I´ve just realized that my samples are sandstones with many mollusca fossils. My problem here is that, I dont know how to extract the fossils without destroying them. Please help me, I need this so much, and I cant find anything about dissolving sandstones. Greetings From Monterrey, México.

  20. Out hunting today on Whitby Jurassic coast and came across this beauty, measures 10", now I have came across bits n pieces of these in the past but never a complete specimen, does anyone know the name and how would I go about prepping this ? Worth polishing for best results ? Thanks.
  21. Ammonite for lunch

    After visiting my crew out in Placitas (short drive from ABQ), I decided to stop at a BLM open space at the roadside. There is a supposed Upper Cretaceous section exposed here and I figured I would eat my lunch and go for a short walk. If there was an K section, it did not look the part... ...the surface of the slopes are covered with Carboniferous (Pennsylvanian) rocks. I mosied along the trail, munching on a granola bar when I spotted some concretions and shale up a gully... ...and upon further inspection, an ammonite! I quickly marched my coiled companion to the truck...back to work! There is definitely some Upper Cretaceous rocks here and well worth a return trip. Planned or impromptu...happy hunting! -P.
  22. Ammonite hunt ID please

    What kind of ammonite is it ?
  23. what is jade ammonite? im hesiting if buying one,but i do not want a fake fossile. also,haw can i tell if it real only by the pic online?
  24. The photos presented here are thin sections of a single chamber of an Ammonite. I recently obtained some broken fossil pieces from "Rocks and Gems Canada " for the purpose of slicing them and making thin sections for viewing through a microscope. The first samples are from a Chambered Ammonite. The area of interest is the filling in the chambers. If I am lucky there will be crystal formation, but most of the time it is just fill. This is a web presentation of the photos below The first two photos are the whole Ammonite as I received it. Photo one is a camera snapshot. Photo two is a stereo microscope composite of the Ammonite. The following photos are 1) Polarized light, 2) Polarized light with a Dark Field filter in place. Photos three and four are a single cell of the Ammonite showing what looks like crystal formations. Photos five and six a 4mm segment of the chamber edge. Photos seven and eight show a 1mm segment of a chamber edge.
