  3. Who can help ?

    Dear all, Let me briefly introduce myself; My name is Marc, living in the south of the Netherlands, i'm 52 (not yet a fossil), I'm a chemical engineer working 5 days a week.... I'm new to fossil collecting; I'm a mineral collector but I recently purchased a collection of minerals among which some fossils. Most of them where labeled, except a few. I've attached a fossil fish and I hope anybody can help me with the determination. The label said "Fossil Fish, Brazil". That's all…... The size is approximately 15" (40 cm). Google search didn't help me solving this question. Thank, Marc
  4. What is this?

    Can anyone tell me what this is?
  5. The first finding of fossilised plant gum has been found in the Crato Formation of Brazil. Belonging to the extinct plant Welwitschiophyllum brasiliense it is dated from around 110 mya. Here is an article about the finding http://www.sci-news.com/paleontology/fossilized-plant-gum-08163.html The scientific paper is listed below and is open access https://www.nature.com/articles/s41598-020-60211-2
  6. Hello everyone, I've looked for a paper about mesosaurs from Brazil but did't find anything online. Does anybody know how can I tell the difference between the two species of mesosaurs found in those permian sediments (Mesosaurus brasiliensis and Stereosternum tumidum)? Thanks
  7. This is very cheap and has some red flags eg patch of resto in the middle but what do you guys think of the rest
  8. Santana formation fish

    Hello all Today this fish came in my mailbox together with a specimen of Rhacolepis buccalis. This fish does not seem to be of the same species, but the skull, fins and tail are in bad shape or even absent. Most of the 'skin' is gone, uncovering some of the bones beneath. I know this will make it hard to ID, but maybe one of the fish experts can help me out. It's from the Cretaceous Santana formation of Brazil and it's about 21 cm long. Thanks in advance.

  10. From the album Insects

    grasshopper, of the order Orthoptera, early Albian age, about 108 million years ago, from the Crato Formation, Brazil
  11. New Triassic Dino from Brazil

    A very well preserved herrerasaurid dinosaur, Gnathovorax cabreirai is described in the attached paper. For us collectors it gives us clues around Carnian age teeth. Unfortunately most of the teeth available to collectors are Norian or earlier in age. https://peerj.com/articles/7963/ Unfortunately the paper does not do a great job describing the teeth, here is what we have: "All tooth crowns are blade like, caudally curved and labiolingually compressed. The premaxillay and dentary teeth lack serrations in their mesial margins. However, in the distal margin there are small serrations that form a right angle with the main axis of the tooth. In the maxillary teeth the serration occur in both margins."
  12. Cretaceous Fish from Brazil?

    Hi I'm looking at this Fish Fossil from the web. Anyone know what species is it? It is around 7 inches long and the following are the location details: Period: Cretaceous - Early Cenomanian Formation: Santana Formation Location: Regiao de Ceara, Araripe Basin, Brazil
  13. Cretaceous Brazil fish id

    Hi Everyone! I need help identifying a fish concretion from the Cretaceous of Brazil. I think it's a species of Rhacolepis but I don't know for certain. The thing is, I was given this by an elderly friend of my dad's over 10 years ago after this fellow heard I like fossils. He told me he got this at a flea market several decades ago and that it was from the Brazilian Cretaceous but he didn't remember what species it was. Then he moved away and passed a couple months later. Definitely one of the stranger ways I've acquired a specimen, but it's the best fish I have (it came with both halves and is pretty three dimensional) and I'd love to know what exactly it is. Hopefully the pictures are decent.
  14. New Theropod from Brazil

    Noasaurinae represents an enigmatic group of small-bodied predatory theropod dinosaurs best known from the iconic Masiakasaurus knopfleri, from the latest Cretaceous (Maastrichtian) of Madagascar. This paper describes a new species from Brazil, Velocisaurus paranaensis . This paper might be a good reference source for material found in the Kem Kem of Morocco since Deltadromeus agilis or may be possibly related to Noasaurinae. Systematic: Abelisauroidea (Bonaparte and Novas, 1985) Noasauridae Bonaparte & Powell, 1980) Noasaurinae (Bonaparte & Powell, 1980) Vespersaurus paranaensis gen. et sp. nov.

  16. Teyuwasu paper

    Is there a copy of the paper I could read: Garcia, Maurício S.; Müller, Rodrigo T.; Dias-Da-Silva, Sergio, 2019. On the taxonomic status of Teyuwasu barberenai Kischlat, 1999 (Archosauria: Dinosauriformes), a challenging taxon from the Upper Triassic of southern Brazil. Zootaxa. 4629 (1): 146–150. doi:10.11646/zootaxa.4629.1.12. ISSN 1175-5334. In this paper, Teyuwasu is considered a specimen of Staurikosaurus, but as noted in the abstract of the paper, Teyuwasu was coined in a symposium abstract, which fails to qualify as a published work under Article 9.10 of the Internation Code on Zoological Nomenclature, so Teyuwasu is a nomen nudum.

  18. Brazil’s Triassic Coprolites

    For those who are interested, this paper on Brazil’s Triassic Coprolites is open access till July 15th. It’s a rather extensive piece, and I must admit I could only briefly skim it, but I imagine others on here may find it very informative. https://onlinelibrary.wiley.com/doi/10.1111/let.12251 PDF version: https://onlinelibrary.wiley.com/doi/pdf/10.1111/let.12251 perhaps it might peak @GeschWhats interest?
  19. ID for Bone found on beach

    Found on beach in Salvador Bay, Brazil. This is the best quality I could get with my phone. Photo with black background shows the curved part of bone well, note how smooth that part is. Color of bone in that photo is most accurate. Can anyone tell me what it is?
  20. Mesosaurus??

    Dear all Would be great if someone could help me with this Fossil. The seller told me that it‘s from Solnhofen, and it was for a long time in a private collection. The only similar fossil I found, is a Mesosaurus from Brazil... Thank you in advance!! Megadiente
  21. Requesting Dinodontosaurus paper

    Hi, Does anyone have a copy of the following paper: S. G. Lucas and S. K. Harris. 1996. Taxonomic and biochronological significance of specimens of the Triassic dicynodont Dinodontosaurus Romer 1943 in the Tübingen collection. Palaeontologische Zeitschrift 70:603-622. I just wanted to have a look at this paper.
  22. Fish from Brazil

    Hi. Brand new here. Over 20 years ago I had a Chinese business colleague who traveled regularly to Brazil. He showed me a beautiful piece once when I was visiting him. A while later he brought me this fossil as a gift. I’ve always loved it but know very little about it. I’m sure this is familiar to you guys. Anything you can tell me about it would be deeply appreciated
  23. Hello, I've been offered this Rhacolepis, it seems it got broken and then repaired, plus it seems there's some paint shade around the specimen. Do you think it's a composite of two different concretions to obtain a fish with head and tail or a damaged genuine one? Thanks.
  24. Hello everyone! As you can see, I'm new to TFF and this will be my first substantive post, so if you have time I would appreciate any help in understanding what this fossil actually is so I can learn more about it. I've tried to follow the guidelines for posting as closely as possible (with limited information regarding collection) but if I have made some mistakes I apologize up front. My wife purchased this fish fossil for me in either La Paz or Cochabamba Bolivia in 1996 at a market. She didn't get any further information regarding where it was collected or what it is. She also purchased another fossil that I'll post later. I do not believe this fossil was actually collected in Bolivia, as it looks like vinctifer comptoni, which I have read is fairly common in the Santana formation in Brazil. But, I am an admitted neophyte and that is simply a guess. What do the experts think this is? I would like to learn more about the fossil and the possible collection area and age, and having an actual identification would certainly help in that! Thanks for reading and I appreciate any information. Regards.
