Hoploscaphites nodosus. 72.94 +- 0.45 million years old. Cretaceous period, Campanian age.
Samuel M posted a topic in Paleo Re-creations
Linked is a 3D model of a nearly perfect Hoploscaphites nodosus ammonite. Models can be viewed using this website: Online 3D Viewer or through other software. This is a 3D model of an actual fossil and is not a "recreation", but since my last upload was moved here this is where I will upload the rest of my 3D scans. If anyone else has any good ammonite or inoceramus finds from Colorado please share them with me and tell me a little about them. I've been reading some of Bill Cobban's papers about the invertebrate paleontology of Colorado and I've gotten really interested in what can be found around here. Thanks! -Sam 1195980117_Hoploscaphitesnodosus-Kprl(1)-1.glb

From the album: Russian Lower/Middle Volgian ammonites
Tatarstan rep., Tetyushi, virgatus zone. D 15 cm -
I feel like I finally hit pay dirt today, my best woodbine ammonite day in my short time looking. I think the smallest one (2.5”) might be a different species? It has 4 little bumps across the top, I notice the rest have fewer. I was pumped to find these! I started out a bit too far in the woodbine, but I grabbed some small pet wood pieces, at least. Far eastern Tarrant county TX

While snail collecting in part of the Britton formation I ran across this amongst the bits and pieces of ammonites and some cruddy crabs. Not much to go on but I'm thinking part of a scaphite from the nodosus group maybe?

These woodbine ammonites are NOT easy to find, but I finally had a lucky murky underwater protrusion grab that proved to be a larger one than I found last time, this one about 3.25” across. I also found some great (for me) chunks of fossilized wood and an entire trunk I’ll have to find some way of retrieving later. The biggest piece of wood is over 9 inches and glistens in the light because of the crystallization, which doesn’t show up well in photos. I found a Macraster echinoid too, which seems out of place, I never find those at the Eagleford/Woodbine border. Is this out of place or do they occur here? I find most of them in Grayson or Fort Worth formations

From the album: Russian Upper Volgian ammonites
A macroconch ammo from Undory, Ulyanovsk oblast. Fulgens ammonite zone, 11 cm -
It’s a sad day. Years ago, I collected a microconch and macroconch of Scaphites so. from the Late Cretaceous Arcadia Park Formation in Dallas, TX that were preserved in pyrite. I’ve collected dozens of pyritized ammonites from this particular site and all have been stable. These ammonites appeared to be stable for about 15 years until one day the pyrite decay started. I noticed it a couple days ago and soaked these specimens in iron out to try to stop the decay. Alas, my attempts were unsuccessful and both specimens crumbled to powder. Beware pyrite, even if you think it’s ok…

Is this the inner whirl of an ammonite or something else? This was found in Northern Minnesota Coleraine Formation. Sorry limited photos as it was donated to the Hill Annex (mine) Palaeontology Project

I got my dremel and I want to prep the Ammonite in the picture. Can someone give me some advice or tip to use the tool and for that Ammonite? I will practice first with some Ammonite fragments. The matrix is kinda soft and weak.

This was found last weekend in the Mounds Reef area and the Ammonite species is Placenticeras pseudoplacenta. The concretion had already been opened by a previous person or less likely weathered out naturally. Anyway this was all there was and I have tuned my eyes for this shape since finding 4-5 partials, one intact inside the concretion and another that had been passed over for looking like a "boring" smooth clamshell to someone else. Is the best way to reveal the sutures the same as polishing rocks or Damascus steel? Start coarse and up the grit until the shine is mirror like? Or use a chemical like muriatic acid? Two different angles of lighting. One pass with 120 grit, skipped to 1,000 grit, then Dremeled some red rouge for a super quick, cheater reveal. They were unseen before hand.

I first stumbled across woodbine ammonites while looking for snakes nearly 8 years ago. At the same spot, I found my first 2 complete ones plus a few pieces of larger woodbines since I started getting into fossils, so it’s been a good weekend! They aren’t nearly as easy as finding the mortoniceras so I’ve been trying to find viable locations along the eagleford/woodbine formation border in DFW area. I’m all ears if you have any hints!

Psittacosaur9's Cabinet Renovation Fossil Identification - Mesozoic and Cenozoic Animals Thread
Psittacosaur9 posted a topic in Fossil ID
Hello everyone, and I hope you've all had a good day. I started to put my display cabinet together today, and after an exhausting day of work, I'm only half done and I haven't even started on the bookshelf! Yay! Sarcasm aside, I've got some more fossils I would like identified, as I am creating labels for my displays. Just as before, I would prefer the most specific identification possible - species would be preferable, but I would rather a genus or clade name over an invalid species name. Location would be helpful too. Again, if any of you want them, I can take more photos tomorrow. Specimen 1: Actinopterygii This specimen I purchased at a museum, which simply labelled it as 'fish fossil'. While I do not know the location, I suspected it was from the Green River Formation in Wyoming, as many commercially available Actinopterygii fossils come from that site. At first, I thought the specimen was Knightia, as that fish seems to be one of the more common from the Green River Formation, and the only common one of the same size and rough shape. However, after recently observing a slab of Knightia at a museum, I began to doubt my initial identification, as the Knightia in the museum looked more bloated than my specimen. Is it a Knightia, or something else? Specimen 2: Ammonite I apologise for the rather shoddy attempt at editing out the supplier's logo. As you can see, I purchased this ammonite in a small plastic case at a museum, and cannot take a photograph of it from all angles. However, the back of the box (or at least what survives of it) says that the ammonite is Jurassic of age and comes from Madagascar (thinking about it, the supplier probably had to stick the ammonite to the case in order to get it through customs). Therefore, after comparing it to other ammonites from the same location, I believe it is most likely a Phylloceras specimen, as those ammonites lived in the correct place at the correct time, and had the same shaped, relatively smooth shell. Do you all agree with this conclusion? Specimen 3: Gastropod Another specimen I purchased from a museum with no knowledge of its original location or age. Unfortunately, I know very little about Gastropods, so I do not know how to identify it. Do any of you recognise at least what group it came from, or even tell its species, time period or location? Specimen 4: Ray tooth I received this tooth as a gift in a set of various teeth from Chondrichthyes. The gift set identified the ray tooth as Jurassic in age, however gave no further information on the specimen. To add to the confusion, all of the fossil ray teeth I have found available to purchase online come from Myliobatis, a genus which only evolved in the Cenozoic. While I am pretty sure it is Myliobatis and the gift set's information was simply inaccurate, I would like confirmation that this conclusion is accurate. Also, I do know that there is only half of a tooth; it broke a while ago and I no longer have the second half. Thank you for all of your help! Next up will be a couple of Triassic plant fossils, and following that will be some fossils I am concerned are fake. Hope you all have a good night!

I want to thank @AncientEarth for the wonderful prep work on this specimen. I'll be excited to pick it up next month. Aaron does really good work and I will definitely use him again in the future.

My first attempt at identification. I hope the pic sizes are ok. I found this in South Dakota. It was my first attempt at finding fossils. Either at the Mount Moriah Cemetery in Deadwood or Badlands. A local expert said it was a shell, possibly ammonite. I'm hoping for a verification. These pics are front and back. ALSO, it feels quite solid but it does have cracks. I was planning to have it made into maybe a necklace for a friend, possibly in a macrame setting. I'd like to make it more solid first. I'd like opinions for how to do this. I've read many ways and products but the opinions are widely varied. Thank you for your time. I have two more fossils and will put those in their own posts. Thanks, Jeff

Is this a legitimate ammonite?
Magma posted a topic in Is It Real? How to Recognize Fossil Fabrications
I bought it recently at a shop for a low price, I was wondering whether it was legitimate because no location was given and it looked way too detailed for how cheap it was.
