  1. madagascan bivalves

    I was wondering that the madagascan jurassic clams and cretaceous cockscomb oysters from my collection did not have a comprehensive label,I wanted to ask you what they were.. Here are a few photos online: https://www.google.com/search?q=madagascar+fossil+clam&sxsrf=ACYBGNSyt5RjY1qraJUr3kcrF1FSPuVtBg:1581930994833&tbm=isch&source=iu&ictx=1&fir=q1GrCKB9r4EOpM%3A%2CRVLU8rvAwW_qDM%2C_&vet=1&usg=AI4_-kRLA3HGjyWBFynUylzJaveHH4B7QA&sa=X&ved=2ahUKEwish4aYoNjnAhXIUN4KHZ2nCtkQ9QEwAHoECAoQHg#imgrc=oy8HBIbkpemGJM

  3. Ammonite help plz

    My dad happened to be in Tucson during the fossil show and grabbed a neat sliced ammonite in a box simply labeled “made in Madagascar” (he knows I’m a sucker for any fossil that had a geode develop in a cavity). I’d like to know a bit more about it, but the info I’ve been able to find about the ammonites of Madagascar is pretty limited and makes identifying pretty hard. My best guess is Desmoceras sp. can anyone be more specific or correct me?
  4. Calling Bug People!

    I bought this bit of Madagascar copal a year ago, then finally got a decent microscope to see the bugs this week. They are less than a mm each. Now I'm stumped. I am a certified *modern* naturalist. I know something about insects. This one fits all the defining characteristics of an adult insect - probably Coleoptera - except that I only see four legs and may or may not have had antennae at some point. The heads are not very clear at any angle. On the bottom view, there are nubs at the end of the abdomen that *could* be legs, but that is the wrong place for insect legs. On the side views, it looks like there might be legs folded backward, as is common with some beetles, but the underside view also does not show any attachment points where there might have been legs that broke off. Any paleo-entomologists out there to point out what I am clearly missing in these pictures?
  5. It’s 5-7 inches big. Iguanodon toe bone is next to it.
  6. Please help identify if possible

    Hey there! New to the group, I was wondering if anyone can help me out with identifying this fossil I picked up in Madagascar?
  7. Whiteia woodwardi

    From the album Fossildude's Purchased/Gift Fossils

    Whiteia woodwardi Lower Triassic, Madagascar Coelacanth. This is a recent bargain I was able to scoop up. Even though it is not complete, it still has great details. It will set off my New Jersey Coelacanths nicely.

  8. Ammonite from Madagascar

    Hello. This is an ammonite from Madagascar. I don't know the scientific name of this. Are both the same type? Please tell me the scientific name of this.
  9. Ammonite from Madagascar

    Hello. This is the ammonite I have. Are these names Aioloceras besairiei? Are these all the same type? Since I am Japanese, I use Google Translate to write this sentence.

  16. Hi fossil forum members, its my first post here after following for a long time this great forum. It seems to me that here are a lot of experts with a lot of experience in key out specimens and that´s the reason I now would like to ask for that expertise. I got this bone 20 years ago and have not touched/preped it so far. It is from Madagascar. Any ideas are very much appreciated and will help to place it in the correct way. Thanks very much in advance
  17. Here is paper on a topic many Dinosaur collectors may be interested in. Unfortunately its paywalled so I rented it to screen grabbed the info to pass it along. https://onlinelibrary.wiley.com/doi/full/10.1002/spp2.1282 Sauropod teeth from the Middle Jurassic of Madagascar, and the oldest record of Titanosauriformes Gabriele Bindellini, Cristiano Dal Sasso First published: 06 September 2019 https://doi.org/10.1002/spp2.1282 The material comes from the Mahajanga Basin, see map, Sakahara Formation (Isalo IIIb subunit) which is dated to the Bathonian stage of the middle Jurassic. At least three sauropod taxa are known Archaeodontosaurus descouensi, Lapparentosaurus madagascariensis and 'Bothriospondylus madagascariensis' (this taxon name is regared as invalid but still used to indicate a Bathonian non-neosauropod eusauropod from Madagascar). Eight Morphotypes were identified. Morphotype J1 are referred to as non-neosauropod eusauropoda Morphotype J2 are referred to as non-neosauropod eusauropoda Morphotype J3 are referred to as a basal brachiosaurid or at least a titanosauriform. Not possible to refer this as L. madagascariensis but some authors would be in agreement. Morphotype J6 are referred to as a basal brachiosaurid or at least a titanosauriform. Not possible to refer this as L. madagascariensis but some authors would be in agreement. Morphotype J7 are referred to as a basal brachiosaurid or at least a titanosauriform. Not possible to refer this as L. madagascariensis but some authors would be in agreement. Morphotype J4 & J5 are assigned to Archaeodontosaurus descouensi Morphotype J8 can be referred to a basal taxon of Diplodocoidea
  18. ID help: Majungatholus tooth

    Is it possible to verify the ID of this tooth? It is marked as Majungatholus crenatissimus from the Maevarano formation in Madagascar. It measures 27 mm. Thanks.
  19. Ammonite ID? Perisphinctes?

    Hi there guys, I got this ammonite as part of a set from Madagascar. I would like to know if this is a Perisphinctes. What caught my attention is that it seems to be more "larger" than the regular Perisphinctes I'm used to, at least. Let me know your thoughts.
  20. Claudiosaurus preparation

    Hi all, I have in my collection, two small complete Claudiosaurus in matrix skeletons, and one round concretion which I believe to contain a larger Claudiosaurus (yes, I know some may be skeptical). I am trying the freeze and thaw method to expose him (or her), and had a set back, as a section broke off at the edge, and another on the right edge. It is a large concretion.. about a foot diameter by 4 inches... just so you know the scale. The matrix looks to be more fragile then what I have seen in other video's.. ie, a heavy hammer strke would likely fragment it into many piece. Underneath the corner section which broke off, you can clearly see what I believe to be vertebrae, though the cleave from the freeze thaw didn't really cleave it in half.. it seemed to cleave in sections, not following the fossil. The right crack is removable, and there isn't any fossil visible under that section.. but it created a nice 'T' that could be chiseled down. The section I'm holding in my hand has split with the fossil on both sides, which is what I was hoping it was going to do the entire way.. The good news is, that the broken off piece has exposed more 'territory' for water to permeate along the fossil natural cleavage, I believe. Those with expertise here. Should I continue to soak several days, and then freeze again.. or, at this point.. hammer and chisel? I am afraid to try anything at this point.. but think the freeze and thaw least risky. I think this is quite a valuable fossil potentially. I have attached a photo of the concretion, and his 'little brother' one of my Claudio skeletons.
  21. I bought this today at a market and would like to know what species it is and if it’s real I’m pretty sure it’s real but you never know the guy that sold it to me said it was from Madagascar and some other stuff but he said it all in a different language so I didn’t know what he said. Sorry for the noob question! Thanks for any help
  22. Madagascan tooth - croc or dinosaur
