Barasaurus fossil real?
Mantelliceras posted a topic in Is It Real? How to Recognize Fossil FabricationsHello everyone, I have recently acquired this Barasaurus fossil from Madagascar and I was wondering if it really is 100% natural as the seller has stated many times to me. I have read a couple of threads in this forum regarding Barasaurus fakes but still have many doubts. If possible, I would greatly appreciate any input from this forum’s experts regarding this piece. Do you think it's real? Please find attached some photos and thanks a lot for your help:

Petrified Wood Slabs
MarcoSr posted a topic in Member CollectionsI'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 m
Mystery Madagascar teeth ID help Croc? Pterosaur? Yes I have good proximity
jikohr posted a topic in Fossil IDHi everyone! I just got in some interesting teeth from the Jurassic of Madagascar Isalo lll Formation (yes I have good proximity. The were found on the outskirts of Boriziny by surface collecting, I included a map) and some of the teeth I'm not sure what they are. My best guess is either Croc or Pterosaur, leaning (hoping) Pterosaur since there is no carina and most have a flattened oval base like the Pterosaur teeth I usually see out of Morocco but then there's one with a circular base that I'm not entirely sure. I saw somewhere that Rhamphorhynchidae can be found within the Isalo
Likely/possible specimens of Tyrannosauroidea from the Southern Hemisphere (Jurassic-Early Late Cretaceous)
Joseph Fossil posted a topic in General Fossil DiscussionAs a freshmen in College, I did a little extra credit report for my geology class about a controversial topic - Tyrannosauroidea diversity in the Southern Hemisphere during the Jurassic-Early Late Cretaceous periods. I was quite surprised at the amount of specimens I found. This diversity likely was the result of an early spread of the early tyrannosaur group Pantyrannosauria into Africa, Eurasia, and North America during the Jurassic and diversified once the land connecting these continents spread out more. Most of these species lived during the Early Cretaceous, though one or two exceptions
Theropod Premax Tooth
Dino Dad 81 posted a topic in Fossil IDHi all, Curious to know what family you think this tooth likely came from. Could it be Allosaurid? From Isalo IIIb in the Mahajanga basin of Madagascar CH: About 27.5mm (estimating for tip) CBL (carina-to-carina): 14mm CBW (mesial side to distal side): 8.5mm Mesial Serration Density: 1.9mmm Distal Serration Density: 2.1/mm Thank you!!
The Triassic fishes from Madagascar: A Guide
oilshale posted a topic in Fossil IDFirst of all, the list of fish found in Madagascar - there are more than 30 species! So many that I can't treat all of them (and I've never seen some of them). There is relatively old, but good literature on it - Lehman has written one of the most comprehensive publications on this subject: J.-P.Lehman (1952) Etude Complementaire des Poisson de L'Eotrias de Madagascar. Kungl. Svenska Vetenskapsakademiens Handlingar. Fjärde Serien Bd 2 No 6 (in French, 244 pages, 340MB!) Australosomus merlei Piveteau, 1934 is easy to recognize: Small
Another Madagascar Theropod Tooth
Dino Dad 81 posted a topic in Fossil IDHey all, Curious to see if you have similar thoughts about this tooth. In terms of that possibility that it's not, in fact, from the Jurassic, I'm not sure I'm seeing the kind of denticle shape/hooking and marginal undulations of Majungasaurus. From Isalo IIIb in the Mahajanga basin of Madagascar CH: About 27.6mm CBL (carina-to-carina): 13.9mm CBW (mesial side to distal side): 7.5mm Mesial Serration Density: 2.2mmm Distal Serration Density: 1.9/mm Thank you!
Madagascar Ammonites - 100% Natural or Repaired
Mulatto_Zack posted a topic in Is It Real? How to Recognize Fossil FabricationsLooking to purchase this pair of ammonites from Madagascar but was wondering if they’re really 100% natural or potentially repaired from pieces of different ammonites. I can’t really tell but the back looked questionable!
Petrified Wood from my Collection
MarcoSr posted a topic in Member CollectionsBelow are some of the slabs/slices/limb casts of petrified wood from my collection. I'll post more pieces in latter replies. I especially like very colorful pieces and unusual pieces like Teredo bored pieces or pieces with fungus. I have hundreds of close-up pictures. If you would like to see close-up pictures of a particular piece, reply to this post with the number/numbers.

The Mystery of the Madagascar Tyrannosauroidea
Joseph Fossil posted a topic in Questions & AnswersA while back, I was researching the number of likely Tyrannosauroidea dinosaurs that inhabited the Southern Hemisphere (I know this is a very controversial subject) in the Early Cretaceous for an extra credit research paper I was doing for my freshmen year college geology class. As I was looking for data for the paper, I found an unusual data entry on the paleontological database website fossilworks.org - It lists Tyrannosauridae remains from Jurassic Madagascar. http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&collection_no=55391 The specimen
Dino Dad 81 posted a topic in Fossil IDHey all, This is supposed to be from Isalo IIIb in Madagascar. Does it look ceratosaur to you? Could it be Majungasaurus with faulty location? I suspect not because of the character on the denticles of Majungasaurus teeth.
help identifying this ammonite
joaoarguello3 posted a topic in Fossil IDHello everyone, I need your help to identify an ammonite. Today I bought one but I bought it in a place where they only sell minerals so when I asked where it was from or more information about the fossil they told me they didn't know. I am not a great expert but I understand that most ammonite fossils are from Madagascar, although I am not saying that this one is from there. My questions are the following: Is there any way to know the age and species of the ammonite? Before making the publication I was looking for a little information and I saw that it is very similar to Phylloceras due to
Rapetosaurus leg bone with skin？
AranHao posted a topic in Fossil IDhey , I purchased this leg bone in Tucson. The dealer told me that is a sauropod dinosaur leg bone from the Cretaceous strata of Madagascar. The key point is that the leg bone is attached with skin. I found that these black "skin" has wrinkles similar to real skin. Is this black "skin" real dinosaur skin? I searched some materials. Professor Kristi Curry Rogers found that Rapetosaurus had skin ossification. I would like to hear more comments, thank you！

Question about a Barasaurus rock
RJB posted a topic in Questions & AnswersI have aquired a slab of rock that has a Barasaurus in it. Not sure if thats the correct name or not. Ive taken a close up of what is exposed, circled in white. Im afraid this is the head? Would so much have wanted the head end in the rock instead of the tail end. What do you guys think? Thanks

elephant bird egg?
Michael D. posted a topic in Is It Real? How to Recognize Fossil FabricationsCurious if this "elephant bird egg" is real. The length and width are realistic and it weights about 3 lbs. 14.5 oz. It is smoother than I expected and appears to have been polished in places, especially in spots where some of the sections meet. Surface covered in fine lines (often with branches) as well as small holes. A small flake was examined under a microscope, showing one of the fine lines to consist of a series of holes. Other holes were also visible. I dabbed the flake with vinegar and observed bubbling under the scope. Images show some close-ups of the textured
