  1. I want to show you three "old" finds from the lower Jurassic in Holzmaden/Dormettingen. They are all big ammonites and because of that not that common there ... I used this three ammonites too practice my new stone cutting machine and it works I am very happy with it and its a new chance for me to solve my "space problem" ... Here is it: https://www.amazon.de/Zipper-Fliesenschneider-ZI-FS115/dp/B00BP7OXLO And i dont want to withheld the ammonites ... 1) Harpoceras falcifer with a maximal length of 28 cm: 2) Also Harpoceras (?) with a max. length of 25 cm. This exemplar need more prep ... And the last one a bit smaller with a diameter of 20 cm but well preserved: I am sorry for the bad photos especially the first looks very nice in real and the photo looks bad ... But thanks for viewing !
  2. I'need to remove some internal moulds/casts of small Ammonites and Gastropods for identification purposes. The Fossils consist of the same material as the matrix, namely Liassic mud/limestones of lower Jurassic age; they're coated with a brown pyritical stain/shell remains. Any advice would be most welcome. I have managed to remove one or two but with not very satisfactory results. Thanks Trog
  3. Hi! I'm a novice collector of rocks, crystals and ammonites. There is just something about the shape, textures or patterns of ammonites that I love. I can't quite explain it. I know my collection is likely laughable as a lot of them came from eBay and are polished or worked on. They just looked appealing to me. I try to do research or ask questions before I buy anything. I wanted to show the ammonites I've collected over the years. Some of them came from the local rock shop and some came from all over. I vaguely have an idea what some are but not sure completely please dont laugh lol
  4. And some geochemistry as well.. A reasonably instructive figure 10(carbonate dilution,cyclicity) reboupittetpalcu3de.pdf
  5. Hi, I will be in Ft worth for a week & can fossil hunt & collect on the weekend 10/8 & 10/9. I've never found an echinoid, trilobite or a ammonite & would like to collect whatever I can . My current plan is to try Jacksboro, Ladonia, & Mineral Wells. I figure lake Texoma is a no go without a boat. I have Matthews' guide & understand any construction site with limestone is a possibility after seeking permission. I'm open to suggestions & would appreciate any other recommendations. thanks

  7. Hi all, Recently saw an opalized ammonite out at a rock and fossil shop in Colorado. It was really quite beautiful but as I'm pretty much an amateur when it comes to identifying fossils, I have concerns about its authenticity. I'm wondering if anyone can give tips on how to spot fakes. thank you!
  8. Good issue of one of my alltime favorite German publication series.Text is in German. Abbreviated contents Alberti on German trilobites(!!!!),alas no line drawings or photographs of specimens Groos on ostracods(paleoz) Foram teratologies a pretty funky and often cited piece by Walliser on the Runzelschicht of ammonites.Required reading!!!! miscellaneous structural geology and petrology http://www.geomuseum.uni-goettingen.de/museum/publications/images/GAGP/pdf/GAGP_Nr 5_Festschrift_Martin_Henno.pdf
  9. Last week i visit for two hours the quarry Mistelgau (clay pit) near Bayreuth. Its not allowed to dig for the "Belemnitenschlachtfelder" (belemnite battle fields), so i concentrated to find some cool ammonites .... But first some pictures in and outside the quarry: Doesnt look spectacular, but its a great place The location where i collected is not on the photo. I collected on a slope on the right of the quarry. You can find many very small ammonites (smaller than 1 cm). For example on this random photo you can see many of them ... But this looks better ... A 4 cm big Pleydellia (?) : And now i want to show some detailed finds: A nice 3.4 cm long unknown ammonite (perhaps also Pleydellia ?) Another ammonite with a length of 2.8 cm ... Looks different, i think it could be Cotteswoldia (?):
  10. The place I used to hunt for ammonites has been renovated, and now the creek is destroyed. I am looking for good places to find ammonites near Austin, Texas. If anyone knows any good places, please tell me the name and where it is.
  11. Just back from my holiday in Scarborough and I'd like to know what these are please. Many thanks.
  12. The second part of my little trip through some quarries in Bavaria. Here you can see the first part: http://www.thefossilforum.com/index.php?/topic/68791-fossils-from-bavaria-part-1/ After my visit in Mistelgau i was in a quarry near Buttenheim. Too bad that it was still rainy so i couldnt search longer than 2 hours (Yes i dont have that much stamina ). I was about 4 times in Buttenheim before (finds), but every time i admire the color of them ... This time i also found some cool ammonites ... The better examples: Most of them arent good preserved and they are often very instable. I think most (nearly all) are Pleuroceras sp. Some detailed photos: The first one is very nice although its broken. The specimen is 4 cm long and well preserved: This one is a bit damaged, but 7 cm long ...
  13. Last weekend i was two days in Bavaria and collect in 4 quarries. Two quarries, which i never visit before and two, which werent new for me ... I decide to post the finds of each quarry in a single topic that i dont have time pressure The first day i was in the quarry Mistelgau (clay pit) near Bayreuth. I am sry that i dont have pictures of the quarry but it was rainy, so i couldnt take pictures there .... I found many small ammonites (around 1-6 cm): I am not sure with ID (i appreciate any help!) .... Some detailed pictures of the nice ones: Maybe Pleydellia (?) Size: 2.6 cm Nice structure on this one ("Lobenlinien") Size: 2.5 cm A bigger one with 4 cm: (Cotteswoldia ??) And a very small one (1.2 cm) ... Maybe Ccallyphylloceras ??
  14. Hi all fossil enthusiasts, I'm very new to the fossil hunting scene-live in the UK and recently went on my first hunt at Charmouth beach on our south coast (Jurassic coast)...loved it so much I plan to go regularly. Having done 2 hunts, I'm wanting to make sure I do right by the fossils I find, and to present them in all their glory. Charmouth is overflowing with Belamnites and also I have found quite a few ammonites already (mostly looking barely recognisable preserved in iron pyrite). For the belamnites,they are already pretty good but wondering if there is anything I should spray or soak them in, now they're fully exposed to air and dry. For the pyratised ammonites, can anything be done to remove the pyrite that is not ammonite (or are they all one entity now?). I also have a piece that appears to b a slatey rock with ammonite imprints...bit worried it could break easily...any advice on how to treat it (see photo). I would also also like help identifying one (photo attached of round fossil on its own)...I thought when I first found it that it was an ammonite,but it doesn't have rings wrapping around it. Could it b something else (or just a central bit of an ammonite with the outer rings lost?). N.b. To date, I have soaked them all in tap water and used a toothbrush to clean mud off...hope that is ok?! If u made it reading this far,thanks so much for your time-any help would be greatly appreciated! K V
  15. On Tuesday, August 30th, I had the pleasure of collecting with fellow members @Pilobolus and @Jeffrey P out in my beloved Rio Puerco Valley. I present a photo collage, from my point of view, of that great adventure with both old and new friends. Enjoy.
  16. Les Vaches Noires is a french famous hunting spot, well known for its Callovian and Oxfordian clays. Some really nice stuff has been found there end of 2016, including croc bones and teeth and plesiosaur bones. Unfortunately, I diddnt got the opportunity to go hunt there during that time. My fist opening windows was during february high tide but i didnt manage to find any reptile stuff. heres a link to the flickr album of this hunt : https://flic.kr/s/aHsktr4d4K So here a global picture of the site. Either you hunt at the bottom of the cliff or on the beach when the clay layer isnt covered by sand. On the left :the beach layer as the tide covering it back : A few in situ pictures : wood (unfortunately most of time hard to preserve) Ammonites (same, depending on the layer they belong to, they often cant be saved) A pyritized small one in situ and a few gastropods (those can be find by dozens in certain layers) Despite i didnt any reptile stuff, the hunt after cleaning appeared to be quite good. some snarge nicely preserved gastropods and bivalves. Here's an appetizer and one of the catch of the day: Gastropod "Pleurotomaria munsterii" with a crinoid article on it : Regards

  20. Ok before I get laughed off the forum, I have to state that I purchased this not knowing if it was real but loving it for the aesthetic factor. Been a long time beachcomber/shell collector and as a result have found some sea fossils over the years, like shark's teeth and fossil shells. I do not know anything about ammonites. I bought this at a store that specializes in home décor and often has a mish mash of imported items. I have seen real shells there as well as agate décor items. I basically love anything with a seashell or sea fossil on it, real or not! Began to look at rough fossil ammonites on line and really can't determine how to tell difference. I do not see any holes in this one produced by air bubbles, which was one thing to look for. I smelled it and I get a clay smell. Have done pottery with clay so I know the smell. It measures about 7" x 7" widest part and about 2 5/8" deep. Weighs 5 lbs 15.9 ounces. I know this came wrapped in plastic with an "India" stamp on plastic before they unwrapped to sell. So you ammonite experts have a go at it and tell me what you see! I love to learn!
  21. Hi all, a while ago (8th February) i went to this spot in Germany close to Aachen with my dad. But i hadn't had the time to take some pictures yet. Unfortunately i didn't take my camera with me so i sadly no insitu pictures. The top find of the day was a nice Hoploscaphites pungens which i didn't expect to find over there as i usually only find shells, belemnites or some Echinoid parts. But when i got home i discovered an additional three (partial) ammonites in a rock we took for no real reason. Which i'm now really happy about
  22. Having a couple days off, and with my wife´s permit... but more importantly with the assistance of a good friend who gave me some good guidance on where to go and is teaching me how to "read the geological maps".... I left Houston and drove north 1 hr past the OK / TX border to scout some creeks that seemed createceous. Some creeks had slim pickings, but one of those creeks was generous enough for me to take home some Ammos, which for an Ammonite lover like me is heaven on earth. I left plenty of those there to share the wealth for the next visitor. Its Weird, I´ve never gone to Texoma to collect and having read here too many stories about Texoma that should be the next trip sometime in late February. If someone has recommendations to which places near Texoma are not top secret but worth a visit, feel free to PM me.... Yeah I know, wishful thinking... Hope you like the ammos.
  23. In november, i had my yearly trip to Troyes area, a bit east of Paris. the hunt takes place on the banks of an artificial lake that has been created to avoid river flood in Paris. The banks can be covered either with silt or dead grass, so you got to look for free surfaces in order to find stuff. From one year to next, grass and slit move, therefore what you can find changes. This year was poor regarding shark teeth but rather good for the crustaceans. We mosstly found crabs carapaces : the usual Notopocorystes stokesii and Etyus Martini including that very fine sample : the less frequent : Cretacoranina broderipii and Eucorystes carteri I also found and that s my first ever, therefore my catch of the trip despite its very modest size : Sabellidromites scarabaea We also got lucky at he shrimp department with several hoplopora sp. Those are always crushed with the head apart from the body but there s sometimes nice details like the legs segments on this one. We also found a good quantity of indet. claws fragments like this one : And to finish with crustaceans we also got that one that get us puzzled for a while : goose barnacle article : Pycnolepas rigida More will follow later with ammonites and vertebrates mostly. You can see more specimen on the galery i dedicated to this trip here : Troyes - nov 2015 galery or on my flickr galery here : flickr of troyes 2015

  25. Roger and I got a replica Allosaurus claw necklace for Toby as we figured it may last longer than a fossil as a necklace - he's a pretty rough and tumble type of kid as y'all may have figured by now. We didn't anticipate that it would have included a small, split and polished ammonite! That was such a pleasant surprise! But before Christmas day, Toby found a larger polished ammonite he wanted to get with some Christmas money he got from my mom and stepdad. We thought that was pretty cool that out of all the fossils he could have purchased, he selected an ammonite, and there was one waiting for him in an unwrapped present! Heck, it's really cool that he wanted to spend his money on a fossil - period! So come Christmas morning, he was very excited to see the necklace and the split ammonite as well. He also made out with Jurassic World toys that he plays with almost nonstop as well as more cards and books for his growing Pokemon and Minecraft collections, and a few other things. The pictures below are some snapshots of Toby's new fossils and the replica necklace. (Sorry for the poor quality) Hope everyone had a wonderful Christmas and will have a blessed New Year!
