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?- 5 replies

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.

Hello everyone, I have recently come across a tooth described as a Majungasurus tooth from the Maevarano Formation. However, the tooth in question does not seem to be from an abelisaurid like Majungasuarus. I have consulted Fanti and Therrien's (2007) paper (attached, but also in the pdf library) on theropod morphology from the Maevarano Formation and cannot find a good match. I have requested further pictures of the mesial serrations and a cross-section of the base. The tooth is described as being 37 mm in length. What do you all think? Fanti and Therrien 2007.pdf

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.

L.S., Thought it would be fun to share this "chance encounter" I had at a mineral show. The photograph below shows a slab of petrified wood from the Triassic of the Isalo II Fm. of Madagascar. When material from this locality is offered for sale (which happens often and in large quantities), it is usually labelled as "Araucarioxylon" or simply as "petrified wood" (where the latter may actually be better). While most of the wood indeed has an "Araucaria-like" anatomy (see Rössler et al. 2014 for a recent discussion on the nomenclature), I recently was lucky enough to "find" something else. While the left-most photograph may not directly show it, the anatomy of this particular slab is quite different from the common Araucaria-like specimens. I tried to clarify the anatomy by contouring the main structures seen, which hopefully makes visible how this wood consists of multiple rings of perimedular bundles and wedge-shaped structures, showing both centripetal and centrifugal xylem (inward and outward growing regions, per as provisionally indicated by the blue and red arrows). This curious growth form (by modern wood standards, at least) is characteristic for the stems of some groups of Mesozoic seed ferns, such as those from the Umkomasiales order. The best-known genus with this type of anatomy is probably Rhexoxylon (see Archangelsky and Brett 1961), but there are more similar genera, making it difficult to arrive at a more specific identification.

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.
