  1. Ammonite ID request

    Hi there folks, me again. =) I'm having a pretty ocious day, so I'm spending my time taking a look at my unidentified pieces. I was hoping if someone can help me with these specimens. They are both from Madagascar so I'm thinking Aioloceras besairiei... Could that be right? In case I'm right, what about this color pattern? Can we figure out about the mineralization process? Finally, ammonoids from Madagascar are generally A. besairiei? Thanks in advance, Juliano
  2. Madagascar Ammonite ID

    Hi there fellow, Bought this from that auction web site and was hoping someone could give me an ID. I know it's been polished and all, so I really don't know what is possible to accomplish with these pictures. Any help would be much appreciated.
  3. Hi, Does anyone ever see black nautilus fossil before? I saw this fossil in online but is kind of too perfect so will like to seek advise from you guys, is this a fake fossil or over process nautilus fossil?
  4. Another fish of interest. Being sold as a Madagascan Triassic Fish - Australosomus merlei 7cm (and a small piece of fossilised wood.) Is this rare / unusual? And real?
  5. Archaeodontosaurus

    From the album Dinosaurs and Reptiles

    My favourite tooth now :)
  6. Suchomimus tooth

    Hi everyone. Please can you let me know what you think OF this tooth? It is being sold as a Suchomimus tooth its from Mahajanga Basin, Madagascar about 2 7/8"
  7. Ammonite necklace repair. Please help!

    Last year, for my very first holiday time at work, I received a bottle of wine and an ammonite from Madagascar necklace from my secret Santa. The necklace was one of the best gifts I have ever received, hands down! I have worn it almost everyday for a year and today, sadly, I discovered that the ammonite is broken. It is still held together by the metal (outline?), but it is loose. I want to save this, as it has a lot of sentimental value to me. I have some Paraloid B72 that is 5% paraloid/95% acetone. Would this be useful if I was able to seal the outside of it? Please tell me I can save it so I can continue to wear it. I feel lost, especially at work, when I’m not wearing it. I’ve uploaded pictures of the breaks, but if there is any confusion please let me know and I can clarify. Thank you so much!
  8. I bought this ammonite at a gem show the other day. It is about 2.5" across. I know it is real, but am curious about how "natural" it is- has it been excessively polished, cut, or otherwise altered? I know most Madagascar ammonites are altered in some way.
  9. From the album Jurassic stuff uk

    Another glass panel with ammonites.
  10. Madagascar Dinosaur Vertebrae

    These are the vertebral bones of a dinosaur from Madagascar. Any idea if we could tell which species it is?
  11. Fish: from Madagascar?

    Hey everyone, Hope no one got trampled during the Black Friday fury! Meanwhile I'm simply at home away from all the craziness Anyways, I got this very nice fossil fish, with both positive and negative, as a gift from a good acquaintance. Unfortunately, no information whatsoever is known about it. So here's to hoping that someone can recognize the species or the matrix, and say from which location it is (and how old it is)! My best guess is that it's from Madagascar, but that's all I can hypothesize... If you have any info that you think is relevant to this fish, please share it! I'd love to learn more about its origin, especially its location. I am aware that this might be very difficult, considering the complete lack of info... But I can still try Thanks in advance! Max

  16. Prep douvilleiceras ammonites

    Hi folks! I got some douvilleiceras that I want to clean up a bit. Ive let them soak in water and then i used a toothbrush and tried to scrape off some of it. It made a minor difference, its like hard clay but not the easiest to get rid off. Do you have any advice what I could do without the risk of damaging the specimens? I do not have any special tools/machines, Just a dremel tool and a engraver.
  17. This is said to be toe bone of a dinosaur from Madagascar. Is it true?
  18. L.S., Thought it would be fun to share this "chance encounter" I had at a mineral show. The photograph below shows a slab of petrified wood from the Triassic of the Isalo II Fm. of Madagascar. When material from this locality is offered for sale (which happens often and in large quantities), it is usually labelled as "Araucarioxylon" or simply as "petrified wood" (where the latter may actually be better). While most of the wood indeed has an "Araucaria-like" anatomy (see Rössler et al. 2014 for a recent discussion on the nomenclature), I recently was lucky enough to "find" something else. While the left-most photograph may not directly show it, the anatomy of this particular slab is quite different from the common Araucaria-like specimens. I tried to clarify the anatomy by contouring the main structures seen, which hopefully makes visible how this wood consists of multiple rings of perimedular bundles and wedge-shaped structures, showing both centripetal and centrifugal xylem (inward and outward growing regions, per as provisionally indicated by the blue and red arrows). This curious growth form (by modern wood standards, at least) is characteristic for the stems of some groups of Mesozoic seed ferns, such as those from the Umkomasiales order. The best-known genus with this type of anatomy is probably Rhexoxylon (see Archangelsky and Brett 1961), but there are more similar genera, making it difficult to arrive at a more specific identification.
  19. Evolute ammonites from Madagascar

    Total newbie here. I'm trying to catalog my ammonite collection and have a few pieces that I just can't seem to figure out. Both of these are evolute ammonites. Each has a bit of remaining iridescent nacre near the umbilicus, which is why I think they're likely Cretaceous fossils from Madagascar. The outermost spiral of the larger one has considerable girth (27 mm across the squared off end), while the smaller one is pretty uniform (9mm at the squared off end) and almost wholly agatized. The small one came from a rock shop in Northern California (Chapman's), and the larger one came from online; both claimed to be from Madagascar. I know some of the diagnostic characteristics have been polished off, but I'd really love to know at least what family or genus these are. Thank you very much for your help! Er...I might have more mystery ammonites after this. Is it less annoying to put them all into one post, or spread them out over a few weeks?
  20. Swedish ammonite?

    Hello, I recently recieved an unidentified ammonite as a present and was told it came from Gotland, Sweden. However, I cannot find any information on ammonite finds from Gotland, and it looks a lot like a Madagascan Perisphinctes to me. Any thoughts? The scale is in centimeters.
