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??

I finally got some time off and had a nice day to hike the North Sulphur River Texas. I hit the fossil park which is the most hunted location but I still managed to find some good stuff. The big piece of coprolite is loaded with shells in it. I really like the well preserved Glyptoxoceras heteromorph ammonite and the big Tylosaur vert.

Split ammonite saligram from India
Roodahg posted a topic in Is It Real? How to Recognize Fossil Fabrications
Thank you for taking the time to read this post. I am taking time during the lock down to have a declutter and I came across this small ammonite in two halves I purchased in India some years ago. I have no clue about its authenticity but I seem to remember the seller telling me it came from a riverbed in Nepal. Let me know what you think, I believe it is a lovely little object - perhaps a paperweight if nothing else! It was bought in a not particularly touristic town in Karnataka state, in a shop selling religious artefacts - take from that what you will.

I hunt fossils in gravel from creeks and the likes. According to the geological survey of similar gravel the age ranges from 200-400 million years ago. I was wondering if you guys could tell me if this was an ammonite or some other sea gastropod. I've found countless other types of fossils but this is the only one like this.

Sometimes I find things in nature on my own, sometimes I purchase things. This I purchased at a fossil and mineral show. I believe it's important to support such shows to keep them going. This is a nice ammonite, I guess some 165 million year-old I suspect this one is from the Jurassic period--it was collected in Madagascar. I've brought this little guy to some small classes I used to teach. It is about 9 inches across.

Once again I slack in posting things on here. last week I decided to dig out a very large ammonite I found last year. It’s a Phylloceras Heterophyllum. Quite rare around here, and to get one as big as this is, is even rarer. It weighed an absolute tonne but worth it. All the prep work is done, all that’s left now is to rebuild some small sections and cracks. It’ll be a stunning piece once’s finished.

I made my second trip to the North Sulfur River today. I had planned on going yesterday, but it was pretty chilly early, and today was forecast to be much warmer, plus the water was still coming down, so I settled for a 50 mile bike ride yesterday, and headed for the NSR this morning. I seem to be making the most of this time of social distancing / off work. A bike ride yesterday, NSR today, and I'll be crappie fishing tomorrow. If this is a preview of retirement, sign me up. Once again, I just went to the Ladonia Fossil Park. I hiked downstream, the opposite of the direction I headed last time. I'm still finding out what my physical capabilities are for this kind of trip. With all my bike riding, my legs are strong, and I'm in great aerobic shape, but at 69 years old, and after almost 50 years of heavy machine shop work, my back and shoulders are pretty cratered. I'm not sure how I'll hold up for long hikes down treacherous river bottoms, or climbing in and out. I probably pack my backpack lighter than most here. But after hiking a couple of miles down the river and back today, I feel fine. So, maybe I can hold up to these trips better than I thought. I'm ready to try getting in and out of the river at some other spots. I drove over to the FM2990 bridge and looked at that access. I'll tackle it, but I'm definitely going to do it on a dry day. That rope climb back up looks tough. I'd also like to try out the river downstream at 24. A question for those who know the area: Google satellite photos show a lot more water in that area, with hardly any sand bars showing. Is the water that much higher there, or is it just when Google took the photos? Do I need to wait for lower water to try that out? Water level today was 2.08. I didn't bring that much back today. There was nothing of real significance, but as always, some interesting stuff.
