Hello everyone! Been some time away from hunting as business consumes now most of my free time. Anyway, around May, I stopped at a small river that I saw while returning from another hunt. I found some stuff including a big Inoceramus (Thx @caterpillar for helping with ID) The place look promising but I could not find further publication or information about that. Searching for geologic maps, I found this site: http://www.geokniga.org/maps and thanks to this and the now known age of Inoceramus, I managed to pin point on map the formation. I searched only within the red area marked. The formation is called Sumer formation (U pronounced as Sumerian, not summer) and its age is Middle Aptian to Albian. On the site, there is another formation of Neogene age, hardly accesible for most of its part. The whole place is absolutely beautiful, you can see pelicans, various species of butterflies and some trouts if you observe in the water. The formation is very big and can be divided in 4 parts. 1st and biggest part is NE of the highway. This part is harder to access as you need to cross the river from the point where it is much deeper, and as it seems on this picture, there is no place where you can prospect. 2nd part is a small strip on the shore of the river and the rest of the formation is under the water. You can see it here. On this point I found the big Inoceramus. 3rd part, you need to walk through the shallow point of the river and you end up again in a small shore with lenght 80-100m. 4th part are the rest areas marked on the map as smK, either not accesible without hiking, or within private properties or just not yet seen by me. So far, I have visited this formation 3 times. My finds: Inoceramus as whole, partial imprints and fragments of shell. Ammonites, yet not identified as there is not a single piece of info for this place. Part of heteromorph ammonite, sadly poorly preserved to collect. Here is the heteromorph, or at least parts of it and the other one I have no idea of spieces. Another unidentified ammo here and next one And here is another (?) Inoceramus I think. The formation has a satisfying yield of fossils, howver most of them are poorly preservated. The sediments are very loose and extremely fragile. Moreover, all fossils from this location are hard to photograph, I guess not enough contrast. The last pictures were taken with a Canon EOS 750D, with settings for micro inside a photobox, however I found it very difficult to properly show the fossils. Made some corrections with photoshop, yet not enough. Time permitting, I will soon visit another place 30Kms SE hoping to find some heteromorps.

My wife, dogs and I got out recently to camp overnight and hike in the Talkeetna Mountains. Still very cool for this time of year at 40 degrees in the late morning upon arriving with frost the next morning. The cool weather made for nice hiking weather and we put some miles in on caribou trails and ridges. At one point I checked out a gully with Cynthia staying up high where she collected two hands full of belamite pieces retaining two of the end pieces. I took pictures of the ammonites I saw in a 1/2 hour side hill jaunt returning to camp at our plane with 7.5 miles covered. I have been studying ammonite anatomy and nomenclature so getting closer to be able to make educated guesses as to what I have been seeing. I believe this area is in Member 3 of the Matanuska Formation probably the Pachydiscus kamishakensis zone per the reference recommended by FossilDAWG. I have several ammonites with the umbilcus cleaned out which will help with identification. A new one to me is ribbed, evolute and unfortunatly broken. Most of what I have been seeing are partially evolute or convolute if I am using the terms correctly, some being fairly large. Will post one picuture of a partially prepared one that I am going to make a grade school guess is from the genus Pachydiscus or Psendophyllites and when fully prepped will post better pictures to help identify. All of this is new to me so enjoying the education very much. Reeeealy steep terrain I did not go out on the hard consolidated areas as poor grip with my boots. Breath taking view and also don't slip here. Belemnites deposit are above the ammonites Orca our stylish Boston Terrier Partially prepared ammonoid with an intact umbilcus

Access to Chico Fm and Cottonwood Creek Ammonites
Anna0704 posted a topic in General Fossil Discussion
Hello. I’m new here, and apologize if I’m breaching etiquette. I have an 11 yr old who lost his beloved fossil collection in the Camp Fire. We had a difficult escape, and also lost some pets. I mention this because my son has been slowly navigating life and PTSD the past year and a half, and has only recently begun showing interest in rebuilding his collection and returning tentatively to the activities he loved. We have hunted at some coastal areas, such as Scotia, Centerville beach, Moonstone beach. Also, pit 5 of the Pit River, and shark teeth in Bakersfield. Embarrassingly, I have been unable to locate exposed and accessible areas of the Chico Fm. We have gone to a few areas of Bidwell park, suggested by park employees, we have had no luck. This is the first area my kid has shown interest in again, and its really helped to pull him out of a difficult time. I have also been told there were some fossils, including ammonites, in an area near the north fork of Cottonwood Creek. Any information shared regarding these areas would be greatly appreciated. Thank you. -
The Anisian (Middle Triassic) ammonite faunas of Nevada have long been known to provide the most complete sequence for this stage in the world, with many genera such as Gymnotoceras, Frechites, and Nevadites being represented in abundance at classic sites such as Fossil Hill in the Humboldt Range. Here I will illustrate three less common to rare forms that are also present in Middle Anisian strata in Nevada. Unionvillites hadleyi (Smith) Provenance: Humboldt Range, Congress Canyon near Unionville Age: Middle Anisian, Hyatti Zone, Hadleyi Subzone A well-preserved specimen showing the braided keel. Reference: Bucher, H., "Ammonoids of the Hyatti Zone and the Anisian Transgression in the Triassic Star Peak Group, Northwestern Nevada, USA" (Palaeontographica 223, pp. 137-166, Stuttgart, 1992). This keeled, tuberculate form has been reported from a few localities in the Humboldt Range. Semibeyrichites sp. Provenance: Humboldt Range, Big Canyon north of Unionville Age: Middle Anisian, Hyatti Zone, Mctaggarti Subzone Reference: Bucher (1992) above. Bucher reported two specimens from the Humboldt Range as the first occurrence of this genus in the western hemisphere. This specimen was found very close to Bucher's locality. Chiratites bituberculatus Monnet and Bucher Provenance: south of Favret Canyon, Augusta Mountains Age: Middle Anisian, Shoshonensis Zone, Mojsvari Subzone Reference: Monnet, C. and Bucher, H., New Middle and Late Anisian (Middle Triassic) ammonoid faunas from northwestern Nevada (USA): taxonomy and biochronology (Fossils and Strata, 52, 2005). Monnet and Bucher proposed this species on the basis of a single specimen from the Augusta Mountains. I have since discovered about six specimens at another nearby locality.

Well my daughter and I have been hard at work hunting we got into it after her birthday and had a tiny bit of success at the beach but found a much better area to dig in the nanaimo group strata. I got "west coast fossils" the book so we could figure out what we were finding and finally these last few outings we are finding some great stuff! My only sadness is I found this huge bivalve but I dont think there is anyway to get it out without damaging it! Lifted a large 5" 2x3' slab off the top of this larger rock and we found this which was pretty awesome first large fossil we have found

Went to Folkestone (Early Cretaceous, Albian) for the second time a couple of weeks ago. Last time I mostly climbed among the big rocks looking in the gaps for fossils but this time due to some poor navigating we accessed the beach from the opposite end this time around. This turned out well though as this stretch of beach has few of those big rocks but good access to the cliffs and slumps. We ended up spending most of the trip picking through the cliff base and fresh fall. This produced some nice ammonites, though it was still difficult to find whole ammonites as is the case with this location. We also found some nice gastropods well preserved, though very delicate, in the clay, as well as belemnites, bivalves and lots of ammonite fragments. My favourite find is the Eutrephoceras clementinum nautilus as I believe they are fairly rare and the colours on it are great. Also the Euhoplites proboscideus is a lovely shade and nicely detailed (Good find boyfriend). ID's are somewhat tentative so if you have any suggestions I'd be grateful. ??

I am going to make the jump and get some prepping tools and looking for recommendations for quality air scribe or scribes from reading the posts believe 2 scribes are needed. My intended use will be to clean out the matrix left in the center whorl of ammonites I have found or future finds as well as bulk removal of matrix to tidy up around the edges to make presentable. I have the support equipment in my shop where I work on one of my other hobbies, building and maintenance of my airplanes. Have attached a couple of pictures of finds from previous trips to give an idea of what I will be working on and hope to get back in the mountains soon as the snow melts.

A resin table made with British ammonites. -
I've been attempting to identify some ammonites I've found, yet they are incomplete, making it quite difficult. I have found a very useful app that had narrowed it down to the most likely few based on location, so I'll attach that, as it could help. They all look so similar . They were found in Northamptonshire, UK. Scale is in centimetres. Thanks.

The back end of our vacation plans got blown out of the water by covid19 so we are making some adjustments. Currently we are slated to be at Theissen quarry in OK in late June. Any chance the water at Lake Texoma is low enough to make it worth the ride? Or any other suggestions in that general region? I am heading east/northeast for home in PA after.

Anyone familiar with Texoma Lake in Texas and Oklahoma? There’s a ton of ammonites there I heard but where specifically? It says Eisenhower Park and a dam area. Are there still plenty there or are these areas depleted? I went to Ladonia Fossil Park Friday and was disappointed by not finding much

Ammonites: Finding and Destroying Fossils for Science
DeepTimeIsotopes posted a topic in Fossil Hunting Trips
Some of you may have seen my ammonite donation. If not and you are curious it is linked here: It is an important player in this trip. Anyway I thought I might describe my first trip to this locality and why you might realize it is a little more rare than the normal finds there. Some of this is part of a poster for the now cancelled Rocky Mountain Section of the Geological Society of America so if I ever do get to put my poster online I will post a link here so you guys can look at it too. For now here is a trip report. -
I'm a life-long fossil hunter and collector. I'm also a mudlarker and amateur archeologist. When I'm not teaching history to my awesome Jr. High students, you can find me outside somewhere digging in the dirt. =) Glad I found this site so I can learn more about fossils and share my finds.

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.

A little report from a oxfordien stage in Provence .J go since 1984 its only place who you can find nodules ammonites whith sometime they are minerals likes diamont quartz,calcite,ankerite and petrol.J collecting just fossils.

As we haven’t been able to get out to the coast collecting we’ve been going through my daughter’s collection and trying to label her finds in the same way as her fossils from various shops. Many have already been identified here, but here are a few that I was hoping to get help with. I know all but one are ammonites but I was hoping for more specific than that. All are from the stretch of Yorkshire coast from Staithes down to Saltwick Bay Thanks in advance

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.

hi guys and girls i would really appreciate some help identifying these ammonites that i've had sitting around for a while now the first one comes from the inferior oolite of burto bradstock and the second could be lissoceras oolithicum,??? oborne wood, sherbourne. dorset, jurassic, inferior oolite, polygyralis zone

I finished up a prep of a nice double ammonite block that I got from the illustrious @RJB as part of a larger trade for a trailer load of smoker wood last year. I think Ron said these were from the Pierre Shale. Is that right Ron? If so, does anyone know the ID? I don’t know these ammonites well. Here they are, happily atop my antique dental cabinet. Don’t judge my photography too harshly.

Since we have to avoid crowded places due to the current situation , it was a good excuse to go out fossil hunting in the open. We went to the beach at the Cenomanian chalk cliffs, and we were in for a big surprise. The day before we got there, there was a big spring tide, the high water levels cleaned up all of the scree piles from the winter landfalls. Lots of fossils were emerging from the lose boulders on the beach, sometimes even just laying around waiting to be picked up. We even got a few new species for our collection: Natalie found a nice Turillites scheuzerianus and I found a straight shelled Sciponoceras baculoides. And of course multiple large ammonites of the more common species like Acanthoceras and Cunningtoniceras. This might be one of the best field trips we ever got at this location. lots of ammo's: After spending most of the sunday prepping: Sciponoceras baculoides: Turillites scheuzerianus:

From the album: Fauna and Flora of the Austin Group in Texas
This specimen is the largest of its genus in my collection, and the largest known to me in any collection. It measures about 7 cm in height, and 4.3 cm in diameter. It retains its tubercles in the most mature whorl sections that are preserved well enough to tell. The specimen is quite crushed. -
Hello all Since I can't go to school for a couple of weeks I have time to catch up with some ID's. Most of these ammonites have been in my collection for years, thinking it's impossible to ID these because of lack of location. Most of these come from old collections without labelling. 1: Only location info: Austria. Nothing more. @FranzBernhard could you help me with this one? About 7 cm in size. 2: I think it was said this one is from Russia, but many locations from this collection turned out to be incorrect afterwards. About 2 cm in size. 3: No location at all. 3-4 cm in size. I know it is hard to ID fossils without location, but I've seen crazier things seen happen here.

Late Cretaceous marine sites in China
The Amateur Paleontologist posted a topic in Questions & Answers
Hey Would anyone know of Late Cretaceous fossil sites in China that are similar to 'typical' Late Cretaceous marine sites in Europe/North America? Like places where one can find ammonites, sea urchins, shark teeth and mosasaur fossils... Thanks for any help! Christian
