  4. Hi, Dactylioceras I have had a while after prepping it, it is pyrite so was a bit stubborn, pretty big Dac though, the monkey puzzle stump is a recent find and is laced with jet, makes a nice stand for the Ammonite or whatever I decide to put on next, wanted to share, thanks, Alan.
  5. Museum Basement II

    You guys were a ton of help with the plant fossils, now it's time for round 2 A little background for those that didn't see my last post, I have been asked to help ID and sort the fossils in a local history museum's basement. I do not have the time or resources to commit to do the job completely by myself, so I am asking for any help I can get. These are mostly bivalves and one ammonite. As with before, I do not know the formations, but they are more likely to be from the New Mexico/Texas area than from elsewhere, although they could be from anywhere. And as I took these pictures last week, we still have a Sharpie as a size reference. Thanks for the help!
  6. Hello everyone, I've recently been put in charge of emptying a fossil collectors secondary collection (the non-prepped fossils he collected himself in the sixties and seventies). I found several plates hidden underneath a built-in aquarium inside a wall, see pictures attached. They seem to be flattened shale ammonites from Whitby, and they seem to be flaking. I guess because they were being used as a crutch to keep the aquarium in place. Is there any emergency prepping, maybe a coating of somesort I can do to keep these plates from flaking any further? Or maybe some tips to safely transport them? I've already moved crates full of smaller plates, but these are very large and unstable. I'm a hobbiest fossil hunter and I've never prepped a plate like this, so any help is welcome. I only have 6 days left to move and secure these plates in one piece. If not moved by then, they will be dumped in a thrash container :(. Thank you in advance!
  7. Hi everyone! Here's my first post on the forum, and I'd like to share an image of a little iron-replaced cretaceous-aged ammonite (unidentified species) which I have photographed recently using a $10 webcam-type digital "microscope". The image is created using a total of 70 individual frames stitched together using an automatic stitching software. The size of the ammonite is about an inch across. As an added bonus, I took the photograph and used it to make some digital measurements to determine how close the shape fits to a logarithmic spiral. The image below gives a visual representation of where I took the data points from (a total of about 12 points). Taking the data points and fitting them onto the logarithmic spiral equation, I get the following result: Note that the axes were incorrectly labelled. The y-axis should be the angle in radians, and x-axis is the natural log of the radius. The close fit to the straight line does indicate that the spirals of the ammonite fossil is close to a perfect logarithmic spiral. Cheers! Ivan
  8. ID on this Ammonite ?

    Hi I found this part of a large ammonite in car boot sale this morning. For the price of a £1 . Does anyone have any idea of the ID. Thanks all Bobby
  9. I got these ammonites a few months ago and I was wondering if I should put any kind of protective coating on them. I have them in storage now. When I display them they will not be near any direct sunlight but I was still worried the color may fade plus the shell is very delicate. I’d prefer to leave them natural but if there is a chance they will fade then I’d prefer to put some kind of protective coating on them. Will they fade over time even if they are not in sunlight? should I coat them or leave them as is? If I so what is the best product to use and how should I apply it? Thanks
  10. Ammonite ID

    Found this cheeky Ammonite last week, well worn but potential on one side, gave it a tap or two and here we have it, first I thought was the centre of a Phylloceras but I'm not convinced looking at it, Yorkshire coast find, cheers.
  11. For Saturday's adventure installment, I threw out invites to several buddies to join me at an artifact pay dig on the Lampasas River. My good friend Anthony jumped on the opportunity. We only found 3 or 4 frameworthy points each, plus brokes, but we had a good time. I got to see Anthony find his first Texas points, while I scored a new type for me (Darl?) and my smallest point ever, a Scallorn.
  12. Ammonites from Morocco

    Hi all, I got those ammonites from @cheney416 in a blind trade. They come from Morocco, but the exact location is unknown. Apparently they are from the Bajocian stage of the Jurassic; 170 mya), but I can't find any Jurassic locations in Morocco containing ammonites... Does anyone know what species these are, and what location they could come from? Thanks, Max
  13. Big ammonite found in Whitby

    Hi all I found a large piece of an ammonite at Whitby, the whole thing would of been more than a foot across. Would be great if I could get what species of ammo it is. Thanks for looking.
  14. Duck Creek formation ammonite ID

    I have no idea what species this is, but I’d like to know if the outer portion is part of the ammonite or just matrix. Debating whether to haul it out of here or not.
  15. WP_20170128_14_07_18_Pro (800x646).jpg

    From the album Lias Ammonites

  16. Picked this up at auction..don’t know what it is. Can anyone help me? Thanks so much. It is very heavy. Has some marking on bottom but can read. Sounds mentally when singing with edge of scissors.
  17. Can anyone identify this

    Found this on the foreshore at Kettleness yesterday (where incidentally there were far less fossils than I have ever seen there a dozen times or more) As anyone any idea what species it is? Apart from this only a couple of the usual Dactilyoceras Peter Ryder
  18. Hello everyone, I'm from Belgium and currently tasked with securing a secondary fossil collection owned by the grandfather of my husband. We are emptying an attic, and securing quite a number of fossils. Many of them already have an ID, some of them however lack one. Apologies in advance for the poor quality of pictures, there is little to no light/electricity inside the rooms we need to vacate, so picture quality will be appalling at first. I am aiming for a basic ID here, if possible I might be able to provide more detailed pictures once the fossils have been properly packed and moved. #1 : Could this be a dinosaur egg? #2: vertebrae of different sizes + plate of petrified wood in the background. Looking for possible ID on these vertebrae. #3: Petrified wood, which type? #4 : Small crustacean? #5: Fossilized shell from morocco? #6: Partial fossilized jaw? #7: Belemnoidea, the two in the front? (they seem to be very large).
  19. Ammonite id help please

    Found this rather large ammonite down at Charmouth on the stonebarrow side. Rather new to the whole identification side of things so any help would be much appreciated ☺️
  20. Saw this on our favorite auction site. The only description is "ammonite from Madagascar". Something seems real funky about this guy. Is it carved to look like this? I have never seen one that has flattened out whirls like this.
  21. Cephalopod Shell Color!

    Hello all! Recently I have been obsessed with cephalopods and realized there is a real lack of reconstructions of the color patterns on extinct nautiloids and ammonites! This led me to compile a list of known fossil color patterns on cephalopods. After a year of on and off research, I found about 90 species of cephalopods retaining official or undescribed, original patterning on their shells. These are the first 15 species on my list. The color markings are based both on descriptions and photographs of the fossil material. The shades of the markings are based on the fossils, but also inferred. I Hope you will appreciate my work!
  22. Ammonite

    This is an ammonite i got in a bundle of fossils last year, they didnt say where they came from and what they were. Is this a Hildoceras?
  23. Hi this is Matt again today I went down to the creek by my house and found a fossil with 3 coral fossils in it so far this has been the best fossil I have this year so far. when I was down there most of the creek was clear of the snow and that was how I found this great fossil today. here is a photo
  24. Okay, help me out here. Somebody posted the following images on the Fossil Forum Facebook group. Not the best pictures in the world, however, the ribbing, keel and overall appearance make it clear that this is an ammonite. However, somebody on the group, claiming to be a highly qualified expert, says that this is in fact a nautiloid, pointing to 'the sutures' as proof. I don't see any sutures, but he says that the ribs are 'external expressions of septa'. Now. I have been wrong before. But, unless I'm slowly succumbing to madness, this is an ammonite. As clear as day. This highly learned man tells me that I am uneducated and don't know what I'm talking about. He is presumably just trolling, but I'm never one to back down from an argument under any circumstances, so I would welcome a second opinion. At the very least, I can pop off down the doctors for a referral to a suitable brain hospital, if it turns out that I've started to confuse different types of cephalopod.
