  1. Madagascar Theropod Tooth?

    Hi all, I bought this tooth recently on an auction site and was wondering what you folks think. The seller bought it at Tucson Fossil show but lost the ID card with the Formation on it, so the locale is missing. Info on the tooth: 1 inch long Supposedly from Madagascar
  2. Circles on Sand Dollar

    I’ve had this mepygurus marmonti sand dollar from the Jurassic of Madagascar for years now and when I was looking at it I noticed these small circles on the bottom. Are these on every sand dollar, it appears to be a part of it so my guess was some sort of way for tiny legs to attach but it’s just a guess the sand dollar is 7.5 centimeters and each dot is just under 1 millimeter
  3. Madagascar Eusauropoda ?

    One of a couple of teeth I'm interested in--figure it's time to add some more exotic teeth to my collection. This caught my eye, Eusauropoda tooth from Madagascar. 0.56 inches, from the Isalo Formation, Majunga, Madagascar. If it's as described, that would be great. Thanks very much. Edit: meant to post in id. Not is it real
  4. Majungasaurus Tooth or Something Else?

    Hello, I have recently received photos of this tooth. It is labeled as a Majungasaurus crenatissimus tooth. The location is stated as Maevarano, Majunga, Madagascar. To me, it does show morphological characteristics of being an Abelisaurid tooth, such as a distal edge that is not recurved. What are your thoughts on this?
  5. New lagerpetid from Madagascar

    A new paper is available online: Kammerer, Christian F.; Nesbitt, Sterling J.; Flynn, John J.; Ranivoharimanana, Lovasoa; Wyss, André R., 2020. A tiny ornithodiran archosaur from the Triassic of Madagascar and the role of miniaturization in dinosaur and pterosaur ancestry. Proceedings of the National Academy of Sciences doi:10.1073/pnas.1916631117. ISSN 0027-8424. Until now, the fossil record of Triassic diapsids from Madagascar was pretty poor, and after the putative 'prosauropod' from the Isalo II unit (later named Azendohsaurus madagaskarensis) was found to be a non-archosauriform archosauromorph (like the Azendohsaurus type species), avemetatarsalians remained absent from the published Isalo II diapsid fossil record, but Kongonaphon, along with an unnamed silesaurid and an unnamed basal avemetatarsalian (reported at the SVP 2019 meeting), demonstrates that early bird-line archosaurs were widespread in Gondwana during the Anisian-Ladinian.
  6. I’ve been slowly working on improving our Jurassic dinosaur fossil collection. One of the major goals has been expanding beyond North America and the Morrison Formation. We recently picked up two fossils that accomplish that goal. Up first we we have a pretty nice sauropod tooth from Madagascar. This is from what is usually referred to as the Isalo III Formation. I believe the Sakahara formation would be the more accurate name given this comes from Andronomamy. This tooth is kind of interesting. It matches the Eusauropoda morphology of a paper published on sauropod teeth from Madagascar. I researched this a bit further to see if I could maybe get it to a family level. This tooth seemed be close to the morphology of the French sauropod Vouivria, which is a basal Brachiosaurid. Based on what I read, Vouivria was described from material that had been assigned to Lapparentosaurus which is what I thought this tooth might be except it doesn’t match the morphology of the Brachiosaurid/Titanosauriformes teeth in the paper. After my brain imploded from trying to figure this out, I decided to just say we have a nice Eusauropoda tooth from Madagascar lol
  7. Its always good to see new publications on dinosaur material from Madagascar since we often see it for sale and misidentified. Here we have a publication that looks at the osteology of Rahonavis ostromi, a paravian from the Maastrichtian Maevarano Formation, Mahajanga Basin, northwestern Madagascar. Unfortunately no functional teeth are described just unerupted ones but it gives us a great description of bones and claws. https://palaeo-electronica.org/content/2020/3060-osteology-of-rahonavis
  8. Madagascar

    Hello Forum members, I live in Madagascar and bought a few fossil teeth at a local market. Or are they claws? Can anyone tell me what kind of these fossils are from. Thanks in advance for all the effort. Ann
  9. Hi, This is listed as a large sauropod claw (16cm in length) from Madagascar attributed to the Sauropod Archaeodontosaurus descouensis. I wanted to ask does it look alright? it states that there is no restoration to the fossil. Thanks in advance!

  11. Fish in a nodule needs ID

    Hi All, I bought a fossil fish on online a while ago. The seller identified it as "PTERONISCULUS Fish fossil Trias 250 mio Madagascar" It would be nice to confirm and also get additional information on possible locality, ideally reference to a scientific publication. I'm really curious about in situ conditions where the fossil was found. Could it be desert, or a mine. It seems like the fish nodules are not that rare if you look on-line but it's hard to find anything about the place of origin. Clearly, recognizing a fish species in this condition is a rare skill. So, many thanks in advance to those who will weigh in and share an opinion and information. Pictures are attached.
  12. Is this specimen a Barasaurus besairiei from Madagascar? Is it genuine? I have seen quite a number of these specimens imported from Madagascar to China but most of them were headless. But more recently, most of the imported specimens are rather complete with head. They are mostly in the form of split nodules, and so it seems like they are genuine. Any views?
  13. Sometimes I find things in nature on my own, sometimes I purchase things. This I purchased at a fossil and mineral show. I believe it's important to support such shows to keep them going. This is a nice ammonite, I guess some 165 million year-old I suspect this one is from the Jurassic period--it was collected in Madagascar. I've brought this little guy to some small classes I used to teach. It is about 9 inches across.
  14. Came across this today, thought someone might be interested. Scientists discover two rare new sharks with saw-like snouts https://www.cnet.com/news/scientists-discover-two-rare-new-sharks-with-saw-like-snouts/#ftag=CAD-09-10aai5b
  15. Dinosaur teeth from Madagascar are frequently misidentified since very little has been published and specific localities are rarely cited, known or accurate. Without an accurate provenance its very difficult to properly assign teeth to any specific genus/species if any are actually described.. Here are a few examples of teeth that are currently being offered for sale. This tooth is being represented as Majungatholus from the Maevarano formation of Madagascar. Majungatholus is an Abelisaurid unfortunately this morphology is not even close to being one. Its an indeterminate theropod tooth. Weak provenance does not help. Below I Included a photo of a Majungatholus tooth. DENTAL MORPHOLOGY AND VARIATION IN MAJUNGASAURUS CRENATISSIMUS (THEROPODA:ABELISAURIDAE) FROM THE LATE CRETACEOUS OF MADAGASCAR by Joshua B. Smith 2010 This tooth is being represented as a very rare Rapetosaurus sauropod from the Maevarano formation. Again the morphology does not even come close to what a Rapetosaurus tooth looks like its spoon shaped not peg like. Below I've added a photo of what one looks like. Weak provenance does not help.. The last of the dinosaur titans: A new sauropod from Madagascar by Rogers, Foster 2001 This tooth is being represented as a Maxillary Bothriospondylus sauropod from Kamoro of Madagascar. The provenance is very weak and the spoon shape points to a couple of possible candidates including Bothrio. depending on formation. Additional cautionary note: The state of accurate identifications of dinosaur material is the worst I've ever seen. Please dont trust anything you see sold online by auction sites, trusted dealers, those you've done business with, other collectors or at shops or shows when they get back up and running. Do yourself a favor PLEASE have everything checked out by knowledgeable individuals

  17. 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

  19. 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?
  20. 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?
  21. It’s 5-7 inches big. Iguanodon toe bone is next to it.
  22. 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?

  24. 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.
