I won't get to do much posting from the road, but since Mike opened the door showing off some of the wisconsin ordovician finds he found and helped my wife and I collect, I figured I would add a teaser from Glendive, Montana where I finally found my first ammonites in the Pierre shale south of town. This little guy was one of my favorite singles because its exposed on one side and completely encrusted with yellow selenite crystals on the other. I will take some clearer pics once we get home and get pieces cleaned up a little

I am working again these days, but on Wednesday, I got off early enough that I made a trip to a creek in northern Hill County. Its limestone walls are full of fossils, but the limestone is very hard. It is obvious that I need to get better at chiseling fossils out of limestone. I could get lots of practice in this creek. Macrostrat shows the area where I was as being right on the border of the Fredericksburg and Washita Groups. The first thing I noticed about this creek was how many Gryphaea (devil's toenail) oysters there were. Most are pretty small, but they are everywhere. There are more of them in the creek than all other fossils combined, including lots of limestone pieces just full of small ones like the one in this photo.

Aloha! Planning a short trip to California before I move further away, I was always fascinated by fossils. Are there any dig sites in California that rent out tools? I would love to find a trilobite or ammonite! Any tips would be greatly appreciated!! Thanks!

Looking to hire someone to prep this monster ammo
joshuajbelanger posted a topic in Fossil Preparation
Hello everyone, I found this bad boy about a year ago in Wyoming. It was in a 100’ ravine and I tore my calf getting it out. I’ve tried to prep it out myself, but the matrix is extremely tough-I’ve spent a few hours with my CP9361, but I don’t have the time, tools, or skill to finish this. I’m guessing that it’s all or mostly in there, but who knows. It’s pretty heavy at around 40 or 50 lbs, but the preserved part that is extruding is very tough, almost metallic. Im looking to pay someone to prep this out for me-I really want to display this thing, especially considering the injury I sustained getting it out of the hole. If anyone has suggestions, or is willing to give it a go, let me know. cheers -J

Hi guys, hope everyone is doing well. In my free time I've been working on properly labeling my fossils. Now, not being an expert, I'm not quite sure of all the ID's but I'm not about to flood the forum with ID requests. So here are some of the ammonites I'm least sure about. If anyone could provide any more information on formations and ages etc. that would be great! Even if its hard to acquire more info on them, it will be a fun opportunity to showcase some of my ammonites. 1. 2. 3.darellia semicostata, burton bradstock 4.label says Dichotomoceras bifurcatoides from the middle oxfordian of poitiers, france, looks like persiphinctes spp to me though

Dear TFF, I have these two Callovian ammonites for exchange. The first is on matrix and wood wax has been applied to it. I would like paleozoic material (especially devonian invertebrates) for my teaching collection, but I am open to other proposals. Thank you.

Found this while I was fishing. Can't tell if it's an ammonite or a rock. It does have that spiral pattern very slightly. Plus, when I turn it on its side, it looks like there's some indication of a small chamber. What's your input? Ammonite or rock?

Hello, Firstly, I would like to thank everyone for their continued support in answering questions for someone who has now ventured into fossil hunting and procurement. I purchased the attached ammonite pair some time ago and I would like to get advice on quality and possible additional restoration I can do on my own. I’m not sure if I can get the dull face better polished. I’m also not sure what to do with the external sides. Is this also a very good quality specimen and therefore, I should put further interest in getting the pair in better Condition? That may be a loaded question as it may be simply a matter of opinion but I’m just interested in professionals’ advice.

Hey all. Couple questions about North Sulfur River Tx. Why can I pull one gastropod that will be black (one species) and then within arms reach (another species) will be red? Both semi covered in the red matrix. Has anyone found a large complete red ammonite? I find pieces of large ammonites but always just pieces. I have found a complete Pachydiscus that is around 6 inches in diameter. That is the largest complete one I have found. Thanks for any help. Still learning this stuff.

I made a hike down the North Sulfur River bottom today, and as usual, there were fun things to be found. There are shell fragments everywhere in the shale at NSR, but most of them aren't from ammonites like this one.

This concretion was actually from a fossil trip last year. Its two ammonites in one rock but the bigger ammo has half of its beak right in front of the appature. Amazing. These are known as Rhaeboceras halli and are from the Bearpaw Shales of eastern Montana. He brought it over to my garage and wants me to 'clean' it up. RB

So, I have no idea where I should post this, but I thought it would interest a lot of people here. I baked a cake that's fossil themed. Attached is a picture. in case you're wondering, yes, those are chocolate fossils. what do you guys think?

Hello, sorry to be a pain with all these IDs. I thought itd be easier if I just put all of them in one post. All were found in Northamptonshire, UK. Which is mostly Jurassic in age. Sorry there's no scale, I couldn't find my ruler anywhere. I'll have to upload more images below this. Its been quite some time since I've found ammonites. The land had just been rotavated, and aside from the ammonites, I found some Bivalves, and two golf balls buried. Thanks. These are the first two ammonites, I tried to ID them, but they are incomplete, so it was a difficulty, the closest I think it looks like is Harpoceras. Each are about two centimetres (about 0.8 inches). I saw a neighbour had a very similar rock with two larger ammonites on them that was being used to hold a fence down.

Hi everyone, I just got into fossil collecting and for some reason Ammonites have my attention. I have a small background in beetle taxonomy, so I was curious if there is a dichotomous key for North American Ammonites? Are dichotomous keys even a thing for fossils? Is there any comprehensive books or guides for Ammonites in English? All I am aware of is the "Treasties on Invertebrate Paleontology" and the fourm search function isn't helping me out either. Thanks in advance.

I justify my going out to fossil hunt right now as "exercise"! Everyone needs exercise! And I have had some really good "exercise" lately! I am to the point in my fossil collecting that it's about finding "better" specimens and the very occasional new thing (which is SO very exciting!) Two in particular have eluded me for a while : Oxytropidoceras Ammonite and Leptosalenia mexicana Echinoid. I have found partials and bits and pieces, but had been unable to find a good one...until now! All are from Texas Cretaceous . The Oxytropidoceras is not the prettiest one in the world, but it's mine and it's a whole one, so I am super happy. 4 inches diameter Fort Worth or Duck Creek Formation This little echinoid has been a real bugger to find. I'd found one, in beautiful condition, only to have it fall apart on me and I found another that is so water worn it's almost impossible to tell it's a L mexicana. So FINALLY I found a lovely one! It's not showing up as well in this photo, but it's a deep purpley grey color! 1/2 inch Walnut Formation And some other good finds - some nice crab claws! Two are unidentified (if anyone knows, please do tell!) and the other is just a nice big one, albeit a bit broken. Unknown crab claw from the Walnut formation: A small unknown crab claw from the Glen Rose Formation: And a honking big Pagurus banderiensis from the Glen Rose Formation: Plus it's always great to find some "better" fossils. Here are a few nice finds: A nice Heteraster from the Walnut Formtiaon; Plus a nice Gastropod Anchura And even a "lowly" bivalve - known as a Texas Heart: Cucullea blancoensis

Hi All, All of this free time to procrastinate during isolation has made me wonder what everyone’s favourite species of prehistoric animal is. I know that there are collectors of dinosaur fossils, shark fossils, ammonites etc so am curious what everyone’s favourite species are and why. My favourite is Baryonyx, closely followed by Allosaurus. Baryonyx because I’m from the uk and it’s a super cool dinosaur. Allosaurus a close second as their teeth are probably my favourite of all Dino teeth available. Keen to know what yours are and why

I walked the North Sulfur River yesterday. I was surprised at how low the water is. There had been a 3 1/2 foot rise at the gauge downstream just a couple of days earlier, but it's obvious there has been no rain at the FM2990 bridge. There is not much water flow at all. No fresh water made me wonder how picked over it would be, but there always seems to be interesting things to be seen at NSR, so down into the river bed I went. I found these two ammonite fragments lying, half buried in sand, exactly in the position in this photo. If they are halves of the same ammonite, there is some material missing between them. These are the largest ammonite fragments I've found at NSR.

I stopped by the North Sulfur River again today, trying out a new area. I didn't bring a lot home. I was surprised to find these three Ammonite fragments. I usually don't find Ammonites at NSR, but after finding a small one Thursday, I found these three fragments today.

I headed out to the North Sulfur River yesterday morning. It was a beautiful day, and as always, there was some good stuff to be found.

In 2013 I was visiting around Buffalo and went to a creek that had been recommended. I didn't come across any trilobites but did find other exciting things. Among them were quite a few pyrite nodules I dug out of the creek bank. Must have found 30 of them. All rounded but varied shapes. About the size of a quarter or a little bigger. I have learned that many people have found them. Some close-ups. Many have a hole in them (shown above) and you can just barely see something inside the hole. Early on I broke some of these open and found... ...pyrite fossils. Gastropod, brachiopod, clam, ammonite. I quit there, I didn't want to smash them all. Over the years, as many who have found these know, some of the nodules began to decompose. What some refer to as "pyrite disease" or "pyrite rot". I have had a number that have broken apart and then turned to dust within a few years. I quarantine those that show signs but haven't had to in the last year or so. I have stored most of my nodules by simply putting them in a sealed container with a desiccant packet, with only a few problems after 7 years. But some ...the first 4 pictures of the post... I keep in a Pyrite display case and they have never shown any signs of problems. And the mini fossils have also never shown signs of decomposition, either. And they are on display as well, not packed away with a desiccant. So...some from the same "batch" decompose while others don't. Why??
