Red Flags on Madagascar Dinosaur Teeth
Troodon posted a topic in Is It Real? How to Recognize Fossil Fabrications
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

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

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?

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?

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.© 2020 T. Jones

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.

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.

I have this ammonite fossil from the genus Perisphinctes, and I would like to know the species. I bought it online from a guy who said it was from a site (which I do not remember) in Madagascar. Can someone help me?

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

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

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.

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.
