Hey everyone. First trade went well so I have another group to trade. I do have at least one more with a mosy tooth I will post either later today or sometime this week. Everything is unprepped except a toothbrush, water and elbow grease. Looking to trade for ammonites. Preferably complete specimens but willing to look at what you are willing to offer. Large Pholodomya lincemani, mini Pachydiscus (P.) paulsoni, urchins from Fort Worth (not NSR but figure I have 150+ of them), 4 mosy verts (mix size and condition. one with the enamel still affixed. species are hard to determine but someone might be able to identify), calcite covered Inoceramus barabini, Turitella trilara, baculite, and Tylosaurus proriger (one side shows great, other has damage as in the photo.

Fossil Friday! Today's FF video post is from Lake Texoma. We made our first ever trip to lake Texoma to search the duck creek formation for ammonites. After much research and planning, we arrived to find we could not access the locations we wanted, so we ended up scouting around. It turned out well and we found some great fossils including ammonites, oysters, clams and echinoids.

Hello, Anyone know what species this is (and if it's legit)? The seller simply calls it a heteromorph from Germany, late Cretaceous ~ 60mya and measures about 10.8 cm long.

Cretaceous Eagle Ford concretion that caught my eye, one part of this disc has what looks like strange sutures but this would be one flat Ammonite if that's what it is so I'm stumped.

Hi all! This is a small trip report from a quarry by the town of Mikhaylov, Ryzan Oblast, situated in 200 km from Moscow. The place is very well known among the public interested in fossils, especially ammonite collectors. There are 4 quarries in a tight group, operated by different companies. Mikhaylov quarry is the most famous of them. The experience is very similar to that of other Callovian - Oxfordian quarries (in my previous reports), but ammonites suddenly take the place of gastropods! Pretty exciting, isn't it? Unfortunately there are not many spoil piles as Jurassic overburden is also used in production and taken to the plant. Another difference is that the site is overwhelmingly Callovian with little Oxfordian part. The ammonites are pyritized. What we see is usually the center of big specimens and small ones, large complete ammonites are preserved as imprints. We had prominent paleontologists in our group and the permission to visit most of the quarry. This trip took place in summer.

I made another trip yesterday morning to the Navarro County creek I visited a couple of times in the last few weeks. I had found everything I brought home last time on gravel bars, but ran out of time, and never got to search some good looking gravel bars downstream. Those gravel bars are actually a shorter hike than the ones I found fossils on, so I've been wanting to come back. I ended up being very disappointed in those new gravel bars. I found nothing. I finally hiked on up the creek to the gravel bars where I'd found stuff last trip, and hunted them again. The day didn't produce a lot. Most teeth were just broken pieces. Here is what I brought home.

Buying heteromorph ammonites, any red flags?
Mochaccino posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I'm considering purchasing between 3 heteromorph ammonites. I wanted to ask if they are authentic, and whether it seems like there is any restoration or carving going on. Also, if there's any one that looks to be in particularly bad condition. Here is #1. Presumably Nostoceras: #2, also Nostoceras, appears upside-down in matrix with turricone still embedded. Perhaps I can prep that myself? And #3, listed as Acrioceras tabarelli:

Hello again. This might be an odd request, but I hope someone is able to help. I bought these fossils in Paris at a shop called "Charion Minéraux". I asked the man who I bought them from to write down some information about them for me. He did a great job, but unfortunately I am terrible at reading other people's handwriting. It also doesn't help that my French is not that good. I can make out some words, but that's about it. I would like to catalogue these fossils in a spreadsheet, so I will need to know what it written on their cards. Any help would be appreciated!

Restored/Composite Heteromorph?
Mochaccino posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, new member here. I just purchased this heteromorph ammonite from what's considered a reputable website but I've started to get concerned on the authenticity of this specimen due to the heterogeneous coloration (some places dark, some places light). Is there a chance there's some fake pieces as a composite or perhaps heavy restoration? Also it was listed as eubostrychoceras indopacificum, but it looks different from photos of other such specimens. It seems more like a Nostoceras malagasyense, but perhaps I'm just mistaken?

I found this item at the trail head of the trail to the giant dinosaur tracks near La Junta, CO. It is ironic that we spend a lot of focused time looking for fossils at likely sites, but this was just hanging out under a tree near the parking lot. This was heavily encrusted with calcite crystal buildup, and other rock, but they came away pretty easily with a Dremel vibration scribe. I do not know if the loop in the center is part of the fossil or not. It is surrounded by the little crystals. Please help me identify what this is. Please offer advise on how to best expose these kind of fossils. TIA

Last Monday, I had a dentist appointment in the morning in Dallas. I left afterward and drove a few miles west to check out a new creek. This part of the creek is mapped as Eagle Ford, but the few fossils I found all appear to have come from a red zone in the outcrop that I've never seen in an Eagle Ford area before, only Ozan. But in this part of DFW, Austin Chalk is between Eagle Ford and Ozan, and they are miles apart. I'll leave it to the experts here to tell me if this is really Eagle Ford. Here are the ammonite pieces I found.

Yesterday, my son and I finally made a day-trip to Lake Texoma for some fossil hunting. We've been wanting to make this trip for while, but it can be difficult between both our jobs and weather, and lake levels. I planned for this trip by searching the google maps for good looking locations with a nearby shore access. Unfortunately, one spot turned into a private drive, and the other was closed off by the Corps of Engineers for some unknown reason. We didnt want to hit the same spot that everyone else goes to so we began just driving and looking. The first place we stopped was a gravel bar in creek. When I drove over the bridge and saw the bar, I immediately made a u-turn. I'm sure that this has been searched, but it didnt disappoint. There were a lot of Gryphaea in the marl walls as well as gravel. We found a couple large segments of ammonites and eventually found a small, complete ammonite, about 2 inches in diameter. Then we drove around the lake roads until we found a likely looking shoreline, which fortunately was only a short walk to the exposure. Hunting started slow, and we could see a couple piles of rejects left by other hunters. But we stayed optimistic and kept searching in depth, and then the finds started to show up. There were huge Gryphaea everywhere, many were 1-1/2" long. I eventually got tired of picking them up. There were huge oysters, but they were mostly broken. I did find a smaller one, about 4 inches across. Then there were many partial ammonites and finally several complete ones. Our favorite finds were the echinoids! I found the first one, and then my son found 3 more, all close together. Some of the ammonites are still imbedded in matrix, and I'm hopeful they will prep out cleanly. One of the small partials I have started trying to prep is having problems. Some of it come out clean, but some spot dont seem to have any separation plane between matrix and fossil (which is a steinkern anyway).

Hi I decided to display a few of my Whitby ammonites. Most are self found, some bought. Some are prepped by me. Some prepped by other people. One of the ammonites on the top shelf isn’t from Whitby. Guess which. Where’s it from and what is it? I’ll post some close ups in due course. Thanks for looking.

Help please! Newbie with Deteriorating Ammonite-type Fossil
starksight posted a topic in Questions & Answers
I started off rinsing with water until I realized it was causing all the fine detail to disintegrate away (I saw little suction cups on the tentacles!). I think it'a pyrite disease? Is it? I dunked it in a bowl of vinegar and it it still there now, hoping to stop the water damage and it seems to have halted the rapid deterioration, but now I'm concerned about the acid causing damage. What should I do next? I read online that a phosphate treatment may replace the escaping sulfur and stop the oxidation and that a recommended field treatment would be common fertilizer. How the heck would I apply fertilizer to a fossil? I do have some chemicals in the house for art in furniture restoration, but definitely not pure phosphate. Again, this is foreign territory. Any help would be greatly appreciated, thank you all! Location: Annandale, Virginia within the Virginia Gold-Pyrite Belt. My neighborhood is in the Cambrian period, but there was a geographic displacement from the Blue Ridge Mountains into Northern VA, not sure how/if that figures into the scenario.
