  1. Spiny ammonite from Whitby

    Found this poking out of a block of shale this morning in the Whitby area; managed to keep the remaining spines mostly intact while starting to prep it. Any ideas on genus/species? Would the pyrite around the opening have resulted from the ammonites soft tissue? Thank you for looking
  2. Hi all! I was finally able to visit the Volga site thanks to a water level/ good weather window. The journey was mostly a success, I got a better understanding of the site, used new means of transportation and examined more of the shoreline. Among the finds were two dozens of marine reptile verts and bone fragments and LOTS of ammonites and other mollusks. Unfortunately the river level was not low enough, 1m higher than during my 1st trip, 0,5m lower than in the 2nd. But it was at least possible to walk the shore. There's still a lot more to do, but now I have a pretty clear idea how to maximize the hunt results for the next trip. The report will be picture-heavy and divided into several blocks I'll be adding in the next few days. Let's start with the scenery.
  3. Ammonite Discovery

    So, a long time ago, I bought a fossil Ammonite at an antique store in Post Falls, Idaho. I posted it here, and one user said it was mostly carved. Heres a picture of when I bought it. Two days ago, I was at a school volunteering for aftercare. I was able to show the kids the fossils I had, including the mostly carved Ammonite. While showing the Ammonite fossil, I realized something. The parts that were mostly carved were in sandstone. When I got home, I was thinking. Using mathematics, I was able to determine that the rest of the Ammonite was UNDER the carved sandstone. Very carefully, I removed the sandstone with a brush. My theory was correct. There WAS more of the Ammonite under the carved sandstone. It looked mostly carved before, but now, it looks about 70% uncarved. I will attach a picture of after the sandstone was taken away in a second, I need to get it to the right file size. Sorry to keep you all in suspense. Jared
  4. Ammonoid ID

    hi all, anyone know the specific attribution of this genus type or direct to any science-based paper? Macrocephalites? mid-Jurassic. ?
  5. Help to identify

    I found this along the river. Assuming it came down from the Bearpaw Formation. My question is regarding the edge of the fossil. I think it is a piece of ammonite but the outer edge is creased. I have been reading that some Ammonites have a keel but all examples I have found look symmetrical. This one is creased on one side and does not look symmetrical at all. Could it have been damaged and flattened that way during fossilization? The nacre on the outside looks like the animal grew this way. What do you think is going on here? Is it a piece of an ammonite or maybe something else?
  6. North Sulphur River 10-2-20

    Here are a few pictures from another recent trip to NSR. Nothing special again but also a few interesting items I have no idea that they are. Anyone know what some of these pictures are of?

  7. First off what are the lines on ammonites called? I was looking at images to find out what they are called and found septa on most but suture lines on some other ones, which is correct? Sorry ammonites isn't my strength. After that I was wondering if the lines had anything to do with age like on a big horn sheep's horns. I was doing some research on them and found that the 4 year old line is the most prominent and was wondering if ammonites had something similar. I thought they might because the last ring ends differently on different specimens, which is easy to tell when half has been cut and polished.

  9. Hi everybody! Today i wanna show you one of my dearest ammonites...Choffaticeras segne! Making a search by keywords in TFF, i found only three results for this species...so i decided to enlarge the number! Now i present you my Choffaticeras segne: it comes from Goulmima in Morocco, belongs to Turonian (Upper/Late Cretaceous), it is 19cm in height and 1.461kg in weight. This specimen has been polished in both sides, obviously. It's very decorative and it makes its good looking part in my living room. I love its external sutures, how do you call this kind of suture in english? Please, let me know! For who loves taxonomy and scientific classification (like me), i leave you a little pattern that i made. Thanks for "watching" Choffaticeras segne Dominio: Eukaryota Regno: Animalia Phylum: Mollusca Classe: Cephalopoda Sottoclasse: Ammonoidea Ordine: Ammonitida Sottordine: Ammonitina Superfamiglia: Acanthoceratoidea Famiglia: Pseudotissotiidae Sottofamiglia: Pseudotissotiinae Genere: Choffaticeras Sottogenere: Choffaticeras (Choffaticeras) Specie: Choffaticeras (Choffaticeras) segne
  10. Whitby Ammonite

    Daughter and I found this in the Whitby area on Sunday; when I looked again at it last night it had already started to crack open so only needed a few light taps. Am I right in thinking it’s a Hildoceras, and can it be narrowed down further perhaps to Hildoceras Bifrons? Thanks for looking
  11. Last Trip of the Season

    The snow has arrived at the elevations that I like to hike covering up the fossil beds now. These pictures are from one of my last hikes in the Talkeetna Mountains and as you can see these are oversized fossils. The ice axe next to the clam is 30". Kobuk and one to the bigger ammonites measured at 65 cm diameter is another whopper. Ok, now a Where's Waldo picture. How many ammonites do you see in the picture? I have the answer and they as still are all still there in the outcrop, some are broken. The answer is nine ammonites. Until next year happy fossil hunting!
  12. North Sulphur River 2008

    Here is a trip I took to the NSR back in 2008 and had some great finds. Many bones and a good Mosasaur vertebrate. I don't know what is in the top center of the last two pictures. Also a tooth of what appears to be a fossil of a more recent mammal is right under it. Any ideas on either one? Sorry I didn't use anything to scale but it should all be pretty typical of the type of fossils from this area.
  13. Hello there, I bought this ammonite fossil several years ago from Nepal. Can anyone help identify what kind of ammonite is this? Thanks!
  14. Hi everybody! Today I’ll show you yet another distinct fossil hunting location within the city limits. It’s situated in the south-east in the direct vicinity of the Moscow ring road (city and regional border). The outcrops are located on the banks of the shallow Shmelovka (Shmelyevka) river, effectively a small fordable creek.
  15. Hi all, I recently obtained several lovely ammonites from the late Triassic (Carnian) Xiaowa Formation of Guanling, Guizhou Province However, I lack the expertise to identify them and I was hoping you could help I suspect A is a Trachyceras multituberculatum as this ammonite type is abundant there, and that species is also the most common ammonite there I can't tell what B and C are. I am not even sure if C is a different species from A. From my research, the following species are also present there: Trachyceras cf. aon Paratrachyceras cf. hofmanni Paratrachyceras douvillei Hauerites cf. himalayanus Protrachyceras sp. Arctosirenites canadensis Arctosirenites columbianus What do you think?
  16. Hey everyone. Yesterday while out on the NSR. I found several new items. I have been able to identify most. I do have two waiting for help in the ID section. But, lets get to why I am here. I found a Pachydiscus (P.) paulsoni piece with a piece of black material sticking out of it. This material seems to "puncture" the ammonite. I am delicately cleaning it right now and hope to have some pictures soon. Of course my thought was a broken piece of a tooth. Could it be a tooth? Or, something other that was burrowing into the ammonite upon its death or after?
  17. Hello Folks, Currently going through the collection with a view to cataloguing and labelling. Purchased this ammonite a few years ago. It was labelled as Peltoceras from the North Yorkshire Coast. It looks like a nodule from that area but the ammo does not look like a Peltoceras in humble opinion. I cannot see the keel either as it is a partial and it is not visible - likewise the whorl cross section. Can anyone help with the id, please? Many thanks, Hamish
  18. Here we see a middle Cretaceous ammonite I recently found. Before cleaning attempt And the other picture is after. I used a dremel and various bits. I wouldn't rate it 100% bad since it is my first attempt using power tools, however I would not recommend it. It lacks accuracy and sometimes the bit moves unpredictably, removing fossil material. Nevertheless, the sample was not something I intended to keep in my collection so I thought to give it a try and verify myself the advice so many people give. Use an airscribe!
  19. Hello, Folks, New to the Forum. I am currently going through the collection in an attempt to systematise it and catalogue it properly before I pop my clogs. I came across this ammonite which I purchased online some time ago. All it had with it was South America Cretaceous, which is a start, I guess. Can anyone please help with possible provenance and id? It appears to be preserved in some sort of black and white calcite, and it occurred to me that it might be from Peru, but I could not find anything like it in any searches. I will attempt to describe it - apologies for any poor use of nomenclature. It has a series of well-defined ribs which bifurcate before they cross the venter. There is no keel and there appear to be four maybe five constrictions per whorl. There are occasional secondary ribs which fade out about a third of the way down the flank. I hope the photos are of more help. Any help much appreciated. Regards, Hamish
  20. Hello. I was wondering if anyone could help me with some fossil identifications. Thanks for any help. First, here is a Green River formation fish plate. I know the fish are Knightia, but I don't know how to differentiate the species. I think they are Knightia eocaena. Can anyone confirm the species? Thanks. Next, here is a shark tooth I found while digging on the Ernst ranch in Bakersfield, California. It is either Carcharodon hastalis or Isurus desori. I'm not great at telling the two apart. Can anyone confirm the species? Thanks. Last, here is an ammonite I received from caldigger. He identified it as Aioloceras besiaiei. I think the species might have been misspelled and is supposed to be besairiei. I've seen these sometimes referred to as Cleoniceras. Does anyone know the difference between Aioloceras and Cleoniceras? Thanks.
  21. Ammonites Id

    Hi I've been gifted a plate with different ammonites in it. As it comes from a second hand store, there's no record for provenance,age and all other infos. I'd appreciate any help with the identification. Thanks Back of plate:
  22. Ice Age & erratics in Lathum

    Hey guys! This hunt was on more than a month ago, on the 18th of July, but I haven't had time to make a trip report till today. Better late than never! In late June I invited my good friend Tijn ( @Hunter0811) to come hunt with me at the Zandmotor, and then come to my place to see my whole collection, and we had a great time talking about all things fossil-related. That evening he told me about a new location he had discovered near his house in the east of the Netherlands which also had Ice Age mammal bones, and so we made plans to meet up again soon, but this time over there, so that we could check this new place out together. He picked me up at the train station and we biked to the place. The weather was nice, although maybe just a bit too warm, but sunny and good for fossil hunting. We had to cross a small field with cows to get to the place after parking our bikes, and they were curious to see what we were doing so they approached us to say hi. The site is near a village called Lathum. It's quite literally a big pile of rocks: gravel with lots of erratic stones, all dredged from the bottom of a nearby pond. The hunting there consists of just looking in between the stones.
  23. Hi and Help

    Hi. I’m new to fossil hunting and collecting its a little hobby my 8 year old son enjoys. We came across this on the beach last year and I have no idea how to open it and if it is a ammonite. Any advice would be very much appreciated.
  24. I took my daughter to the Natural History Museum in London last year and the highlight was seeing Mary Anning’s ichthyosaurs, so we’ve been planning this week away ever since. Unfortunately we haven’t found any bones yet but we’ve found a few nice samples that I’ll get up here once we’re home. Here’s a few pictures from today’s walk along Monmouth beach, hunting in the land of giants!
