From Madagascar Probably Mesozoic Why is this fossil lying on its back .looks like a parrot's beak. ---------------------------------- These are some of the details that prove it's a fossil It's a very damaged fossil It preserved conical foramina, and preserved neural crest vertebrae fossils are rare in Madagascar So what kind of animal is this? Detail the rupture above the neural crest is seen to form a square inconsistency The fractures on the spine have detailed bone patterns Thank you for your answer. --------------------------------- Thank you for your insights. I've seen many kinds of vertebrae from Madagascar, but this one is very special, very strange. But I also want to ask: why is it in this form? Like a lie? As I've drawn it: the red is a separate spine, the yellow is another spine; The blue one is the nerve, why is it so combined,？ what range of animals is it?

发现于马达加斯加。 无法确定具体的产地。 它可能来自 Maevarano 组。 是脊椎吗？还是股骨？ 感谢您的回答！

Please help me identify the genus of this ammonite, it's from cretaceous/Madagascar, .Thank you very much!

Hello, Is this fish fossil real? Listed as Pteronisculus from Madagascar, length 12cm. Any apparent reconstruction or fabrication? And how complete is it? Looks like the tip of the head may be cut off. Thanks.

Hello all I was offered this beauty from Sakaraha formation, Mid Jurassic (Bathonian) of Madagascar. It is ID'd as sauropod because there aren't any ornithopods known from the formation. What do people here say? It's 8 cm long .

I just acquired this fossil recently. Can anyone provide some thoughts on this fossil? ID also, please. Is this a Barasaurus? Thanks!

Any idea which species this is? The ammonite is from Madagascar, but I don't have the exact location. Size 26 inches, weight 120 kgs

... a Barasaurus besairei, from the Triassic of Madagascar. Which if true wouild be an interesting specimen. Any chance of it being real?

I bought these fossil wood years ago. I think these may be from Madagascar not sure of age though. Does anyone know?

I'm interested in petrified wood for the scientific value (wood where the cell structure is well preserved), for the aesthetic value (mineralized with vivid colors and crystal shapes), and for oddities (like fungus, insect borings etc.) contained in the wood. Below are three petrified wood slabs, from the United States, from my collection. The below individual slab pictures were taken with the slabs dry, indoors using my camera with flash. The close-up pictures were taken with my Dino-Lite digital microscope. If you want to see a lot more of the petrified wood pieces in my collection, check out my TFF thread at the below link: Petrified Wood, conifer, fungus Polyporites wardii, early Permian late Triassic 295 to 201 MYA, Chinle Formation, northern Arizona - 3.60 lbs. 10.5x8.75x0.53 inches Traditionally this petrified wood has been identified as Araucarioxylon arizonicum, a conifer tree. However,according to Wikipedia “ The validity of the name Araucarioxylon arizonicum has been questioned. A. arizonicum may actually be composed of several different genera and species. A 2007 study on the syntypes used by Knowlton in describing the species has revealed that they belonged to three species. They were tentatively reclassified as Pullisilvaxylon arizonicum, Pullisilvaxylon daughertii, and Chinleoxylon knowltonii. The genus Araucarioxylon may thus be superfluous and illegitimate; and the petrified logs of Petrified Forest National Park may be composed of a greater diversity than initially believed.” What makes this slab unique are the oval shaped patterns framing and permeating the piece, which are actually the fossil remains of a fungus (named Polyporites wardii), that invaded the ancient tree before it was fossilized. The fungus is preserved in barite (fungus is almost never seen because it doesn't preserve in silica the way wood does). Petrified Wood, Triassic 225 MYA, Chinle Formation near Holbrook, Arizona - 745g 160 x200x12mm This slab has incredible colors (purple, red, orange, yellow etc.) which is a major reason why Arizona petrified wood is highly desired by petrified wood collectors. Petrified Wood, early Eocene 50 MYA, Green River Formation, Blue Forest along ancient Lake Gosiute, Sweetwater County, Wyoming - 1.2 lbs. 8.5x6x.38 inches This slab has really nice wood preservation with a very well defined heart in the center and stunning wood grain. There is blue agate, with golden calcite filling some of the agate voids, some nice insect borings, as well as fossil ostracods near the rind. Per Viney 2020 The Blue Forest of Ancient Lake Gosiute Sweetwater County Wyoming “The lacustrine setting in which the silicified wood formed is contrasted with two geologic environments commonly associated with silicified wood deposits, trees transported by streams and rivers buried in fine-grained fluvial sediments of deltas and floodplains as well as lahars and ash produced from volcanic eruptions that bury trees. A recent scientific study of the Blue Forest fossil wood reveals that preservation occurred as a multistage mineralization process. The taphonomic sequence that included stromatolitic growth followed by wood desiccation and then exposure to mineral-laden waters is consistent with a playa-lake model for Lake Gosiute.” Marco Sr.

From Madagascar. I don't know any other information. According to the fossil merchant, it's the Cretaceous. Length, width and height, 15, 12, 22. What part is it?

This is a fossil from Madagascar. Mahazanga. I don't know the rest. Is it a vertebra? Or some other structure?

May I ask you. What is the abnormal structure of this fossil? cancer? Teeth? trauma? This is a fossil from the province of Mahazanga, Madagascar. I don't know about other information.

Hi guys, since my last post about a misterious creature from the Cambrian of China was unsolved (lol) here another easier guess: A friend of mine gave me this, undoubtedly an abelisaurine tooth, with a straight distal carina and lightly curved mesial one. The provenance of this tooth, as he claims, is the Maevarano Formation, or other cretaceous outcrops but surely from north Madagascar, but even if I trust him and he would have no reason to lie, I am not sure. Know it's only an assumption (read all the previous post about the indet. teeth) Have tried to ask some other collectors on socials, but no one offered me help with this. Tried to match with the preservation and colors of ones belonging to the specimen FMNH PR 2100, the dentary dentitions, and the FMNH PR 2008, the premaxillary teeth (mine isn't, the section isn't so thick and the serration aren't on the same side), but don't know. Maybe a lateral maxillary one? The serration density on this tooth is almost impossible to take at the moment, and also most of denticles are worn. Now I have the chance to post only this photo, but soon I'll make more, I promise! Anyway is a gift from a friend, so I would be sad knowing that maybe he paid it more than he should worth if it isn't a Majungasaurus, as we both hope As always, thank you guys for your time and experience!

This reminds me a little of some of the Madagascan Cleoniceras ammonites, but the sutures are... unusual. Somewhat rounded at the ends. It's 86x69MM approx. I'd appreciate any input.

Hello, I really need some help identifying what formation my Ammonite fossil is from. Its been dated to the Albian epoch and is from the Mahajanga province, Madagascar. Unfortunately nothing about it says what formation it could be from. I've done a bit of research and the closest formation to what I'm trying to find is the Ankarafantsika Formation. The problem is that, that formation is dated to the Cenomanian. Any help would be great! Here's a picture

Some time ago I bought this unidentified Madagascan fish online. Any ideas what species it is? Thanks

Any idea if this bone is a dinosaur vertebra? It is from Madagascar but unfortunately no further information as to its exact locality/formation. The seller said the nerves are also preserved, is that so?

Sorry for the necro bump but I saw this online, a large palaeoniscid from Madagascar? Any idea on genus or species or is it something new? EDIT: sorry about the link
