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."

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

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.

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.

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?

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

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

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.

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.

would you like to know what animals and body parts are these fossils found on a beach in southern Brazil.

Founded in 1818 and housing over 20 million items, the National Museum of Brazil caught fire today and may be a total loss. Does anyone know specifics about their paleontology collections? I imagine the mineral collections included priceless specimens... http://news.trust.org//item/20180903001032-p13t9/

Hi! I've found that rock on a cliff near some fisherman houses by a beach here from my town. There are some vulcanic rocks on the area too. Here are some pictures of the rock. I found those "plant marks" strange. Could that be a fossil?

For us Spinosaurid Geeks.. Interesting paper where Spinosaur histology is here described for the first time. Although Paywalled there is lots of supporting documentation that we can abstract good info Article http://www.eartharchives.org/articles/brazilian-sail-backed-dinosaur-swam-long-before-spinosaurus/ Blog is full of information. http://novataxa.blogspot.com/2018/05/spinosaurinae-romualdo.html Paywalled paper Aureliano, T., Ghilardi, A.M., Buck, P.V., Fabbri, M., Samathi, A., Delcourt, R., Fernandes, M.A., Sander, M., Semi-aquatic adaptations in a spinosaur from the Lower Cretaceous of Brazil, Cretaceous Research (2018), https://www.sciencedirect.com/science/article/pii/S0195667117305153 Density of bones, typical of what we saw in the Spinosaurus paper. Good future reference. What I find interesting is the density of the crock bone in blue. We see a number of hollow bones in the Kem Kem.

Let's talk a little about Brazil For some years now I would like to talk a little about Brazil here at TFF, and I think the best opportunity has finally come! In fact, Brazil has not only banned exports, but also banned the commercialization of fossils even within the country, and Brazilians can not collect fossils from their own country, as they can take many years in prison! And with so much banning, even world-renowned Paleontologists (I'm a big fan of this great scientist) pterosaurs experts wrongfully get arrested by mistake: http://www1.folha.uol.com.br/ciencia/2013/12/1389270-paleontologo-brasileiro-que-foi-preso-processa-governo-em-r-1-milhao.shtml And currently a new law is being created in Brazil to make it even more criminal (with more years in prison), to have Brazilian fossils in a collection, to sell or to buy! Meanwhile, trillions of tons per year of Mesosaurus tenuidens fossils are being crushed and turned into dust by Petrobrás, in Irati, Paraná, Brazil, for the exploration of oil, gas and sulfur. The Brazilian government knows that in this process trillions of tons per year of Mesosaurus tenuidens fossils are being destroyed, but even so it grants authorization! The Santana Formation is located in the state of Ceará, Brazil. It is extremely rich in pterosaurs, dinosaurs, crocodiles, fish, insects and other fossils, mainly due to the clear condition of excellent conservation. An amazing beauty! But the State of Ceará is also the poorest in the whole of Brazil, even in many regions there is not even water to drink, many months without rain and also there is nothing to eat, being a population that in these regions lives in the most complete misery; On one side, a miserable population, without food and without water, literally living on an incalculable fortune of dinosaurs, pterosaurs, fish and many other fossils that are common in that region, that is, they do not represent any novelty for science, and often to have something to eat, some even challenge hard laws to sell a small fish fossilized at US $00,25! And meanwhile, on the other side of the rope, the Federal Police of Brazil seize fossils, and arrest people on charges of: Crime of usurpation of Union good and crime of qualified reception! And meanwhile, tons of fossils that are not unpublished, but rather common and old acquaintances of science are accumulating in the holds of the Brazilian Federal Police... And meanwhile, in Brazil, sensationalist newspaper articles publish the following: "Fossils of great scientific value seized in operation of the Federal Police..."! But as incredible as it may seem, the Brazilian government authorizes the commercial exploitation of rocks from the Santana Formation to make slabs of pavements and wall coverings, where the fossils will simply spray and disappear with the passage of time between rains and sun strong; And if you are a Brazilian, you can have your fish fossilized or any other beautiful fossil spoiling with the action of the time on the floor of your house or lining the walls and walls, after all, you bought the lage, paid for it and have invoice , but if you decide to cut the rock and fondly keep this fossil inside your house to protect it, you'll be arrest in the act! In this process, mountains of fossils are destroyed... In the cities of Assistência, Ipeúna and Piracicaba, in the State of São Paulo, Brazil, the fossil of the aquatic reptile Stereosternum Tumidum Cope is very abundant: But in these quarries, billions of tons of Stereosternum Tumidum Cope fossils are exploded and milled a year to be transformed into lime, used in agriculture and cement for civil construction. And all this with authorization from the Brazilian government! And if you visit one of these quarries and try to save from destruction one of these Stereosternum Tumidum Cope skeletons, you'll be arrest by the federal police in the act! I'm forgetting something to close this post with the golden key? Oh yeah! One of the most beautiful dinosaur footprint in the world is in the city of Araraquara, in the state of São Paulo, Brazil! But the footprints are dynamited and explored to make lages for the pavement of the City and that region! And now where are these footprints that have been saved from the dynamite? On the sidewalks of the whole city and the whole region, where people step on and the action of hot sun and rain, and the very friction of people trampling over, gradually destroys what time has taken millions of years to conserve! And before I forget, the "Museum in the open" was created, the only museum in the world that you can see the footprints and jump out and trampling on them the way you want! But if you want to get one of these footprints in the quarry and take it home and keep it with affection, you go to jail in flagrante by the Federal Police of Brazil! You are only allowed to put on the sidewalk of your house and destroy the footprints trampling over them with your own feet or with the tires of your car! Unfortunately unlike many first world countries, in Brazil the people are prevented from working honestly of what the earth gives! And if you want to work you can be arrested by the police. These harsh laws about the "fossiliferous heritage" do not favor the people, who, even in a miserable state, tread and live on top of the riches they can not reach... The sale of common fossils, already known by science, could bring billions of dollars a year to the Brazilian people. Paleontologists could be hired to inspect what could leave Brazil and unpublished materials that should remain... And the current harsh laws are also not at all favorable to Brazilian Paleontology, since the Brazilian Federal Police does not have the resources to watch over the Santana Formation, which is so huge that it borders on three Brazilian states: Ceará, Piauí and Pernambuco . And with the harsh current laws, only the stone flake remain for Brazilian paleontologists, while the complete fossils of scientific interest go to private collections around the world. Like this rare skull of Pterosaur Ludodactylus sibbicki that was auctioned in Paris: I could give hundreds more examples, but I will limit myself to just giving this example of the rarest pterosaur Anhanguera santanae that was sold on our favorite auction site for 200 Thousand Dollars! And in the midst of this crossfire, as I mentioned earlier, even internationally renowned paleontologists are arrested by mistake... People can not buy, people can not sell, otherwise they can be arrested for several years by the Federal Police. Paleontologists do not have the money to carry out scientific expeditions within their own country ... The harsh laws are not protecting the fossils, they are not protecting their people and they are not protecting the Brazilian Paleontology either. I wonder who this is benefiting... If you did not know the reality of the Brazilian Warrior People and their spectacular fossils, I hope this post was informative!

I found this fish for sale online. There is only one picture and not a very clear one. It's simply described as rare fish. Can anybody tell me if this a fish from the Santana Formation in Brazil?

Good morning to everyone from my favorite forum! Now that the fish fossil Rhacolepis buccalis has become famous all over the world: http://cnpem.br/fossilised-hearts-found-in-prehistoric-fish/ At our favorite auction site, there are several ads for fish fossil that are listed as being of the specie Rhacolepis buccalis: It is possible to notice that the eyes were roughly pierced by human hands, and thus falsely simulate an ocular cavity: Nevertheless, we also have here a real Show of fins violently painted by human hands: Proudly, the seller places on the ad that: This is a new find from Mozambique! But I would like to clarify here that fish Rhacolepis buccalis, only occurs in Santana Formation of Brazil, never this fish species has ever been discovered in Mozambique or anywhere else in the world! Besides, the fish specie Rhacolepis buccalis is completely different! Look at the real fish Rhacolepis buccalis: Even the type of rock matrix is completely different! I've tried to contact the seller, but he ignores me. I've tried 5 times to report it but the site also ignores me. So here is registered all my indignation so that you do not be deceived when trying to buy for your collection a "shark" that in fact is a "sardine"!

@Fossildude19 Someone brought this fish to me today wanting to know what it was. It was purchased at a thrift store or antique shop or some such place. I think It looks like Santana Formation, Brazil. I was thinking perhaps Vinctifer sp.? Can anyone confirm or correct any of this? It's about ~30 cm long Thank you!

I found these while doing some prep. on fish in a Brazilian concretion. They have to be seed shrimp. Right ?

Hello, Could you please help me to identify the following fossils ? I know they come from Brazil and after doing some research I think they are from the Santana do Cariri area. Here are the measurements of the different specimens: 1 : 28 inches 2 : 24 inches 3 : 11 inches 4 : 10 inches Thanks !

And these two fish? Somebody knows?
