Hi all, I recently became aware that Madagascar appears to have a fully developed and interesting Mesozoic marine reptile record, yet am not particularly able to find any information on them. The only article I have come across is Bardet and Termier, 1990, "Première description de restes de Plésiosaure provenant de Madagascar (gisement de Berere, Campanien)". However, I've been unable to track this article down. As such, I was wondering whether anybody on TFF might have any information on them. Basically, I'm starting from scratch, so would be very interested in the clades of marine reptile that are known from the region, if not recognized genera or even species. What formations have remains been found in, to what stages in earth geological history do these date, and where geographically are these located? Ideally, there'd be some open-access articles I could refer to, yet any bit of information is welcome. Thanks in advance!

I saw this from an online store. It was said to be a toe bone of a dinosaur from Madagascar. It is pretty large, is it really a dinosaur toe bone?

I bought this cleonaceras ammonite a while ago. It’s 110 Million years old from Madagascar. It said it was filled with mud and when I was looking at it I saw many small fossils, some of these may be unidentifiable or even not fossils but I know some are and want to see if you guys can help narrow it down. Since they have been polished the inclusions on one side are not on the other here’s the ammonite, 6.9 inches the longest way 1. Gastropod? 2. Shell fragment? 3. Shell fragment? 4. Gastropod? 5. Gastropod? 6. I know this ones a gastropod, anything else? 7. Shell fragment? 8. No clue, probably not a fossil 9. Tiny gastropod?

Hi people. I found this fish in the Malagasy mountains in 2014. I think it's a Piveauia madagascariensis Lehman, 1952 ?? To get to the site we have to walk in the mountains for 4-5 hours, depending on the site we want to visit, for me it was a fabulous period, not only for the fossils, but also for the discovery of the way of life of the Malagasy, the all those that surrounds it. Merry Christmas and Happy New Year 2021 !!

Dr Krause does it again. Another mammal from the Cretaceous of Madagascar. Named the "crazy beast" in hybrid Malagasy and Greek. Also named after a colleague who passed away. Weird reading about people you've worked with and met. My wife did unrelated research with Dr. Hu too. Don't get fooled by the picture at the top of the page, it is from a gallery of extinct creatures https://www.cnn.com/2020/12/18/world/crazy-beast-fossil-mammal-scn-trnd/index.html

Hello TFF, I purchased this relatively inexpensive specimen at Mineralfest this past fall, and I was wondering if anyone could tell me more about it. The seller informed me it could possibly be from Madagascar, but was transparent in admitting that she couldn't confirm for sure. It was with other pieces of petrified wood that were brown, but I was drawn to this one due to the red hues. I think it's agatized, and it looks "glassy," although there are too many impurities to shine a cell phone light through it. One side is polished, and I put water on the rougher backside to show more of the details in the coloration. When I went to research the process of identifying tree species from petrified wood, I came across high powered microscopes that could identify structures on a cellular level. I don't have access to that sort of technology, but I was wondering if anyone has any guesses as to what the species could be, how old it might be, what it might be made of, or any other information that could be gathered from looking at the specimen. I'm always curious about what the prehistoric "story" could be behind a fossil, or anything related to the unique biology of ancient life. Thank you for your time, and your knowledge is greatly appreciated!

Hello, I have been collecting fossils for 30 years, my interest is in cephallopods, echinoderms and fish. I came to this forum to exchange ideas and information, to present my research and my specimens from Madagascar and other corners of the globe. I look forward to sharing with this community. See you soon

Good evening folks. I just received a fish fossil from the Cretaceous period of Madagascar that is just listed as a "bony fish". Can anyone put a name to it?

Hello, I'm interested in getting one, maybe both of these. Sold as Borthriospondylus, but, unless I'm misaken, that's a name attached to fossils to sell them and a better labelling is Eusauropoda. Anyway, unfortunately, there is no formation, I emailed seller and he doesn't know. But both teeth are from Madagascar, 164 million years old. I was wondering, are they both from the same species? While they both look similar and have a similar shape around the base, tooth number 1 has a flatter top--does this mean they're from two different species, or does it just have more feeding wear than the others. Incidentally, tooth number 1 I found has been posted here before a couple of years ago--ID'd as Eusauropoda. Tooth 1 - 15mm. Tooth 2 - 17 mm Many thanks.

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

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

Majungasaurus is the only abelisaurid from the cretaceous of Madagascar which has led to this identification. Appears to have been possibly added to the block of matrix.

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

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?

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.

Some cool Jurassic Dino teeth that are not Morrison Formation
fossilsonwheels posted a topic in General Fossil Discussion
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

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

Does this Sauropod claw look real?
msantix posted a topic in Is It Real? How to Recognize Fossil Fabrications
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!- 7 replies

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.

Barasaurus besairiei from Madagascar
Crazyhen posted a topic in Is It Real? How to Recognize Fossil Fabrications
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?
