  3. Image of a Reconstruction of the Caiman Mourasuchus and Prehistoric Dolphins in Miocene Venezuela by Julio Lacerda Image Source: https://www.facebook.com/art.julio.lacerda/photos/mourasuchus-was-a-very-large-caiman-with-a-distinctly-flat-head-and-numerous-sma/2971939362916938/?_rdr In the Northern and Central Basins of Miocene South America between 23-5.3 Million Years ago, there was a giant system of lakes known as Lake Pebas. Fed by rivers directly connected to South America’s Caribbean Atlantic Coast, this lake system at its largest covered an area slightly bigger than 1,000,000 square kilometers (km2) in what is today part of Brazil, Colombia, Peru, Venezuela, and Bolivia. The lake system was home to a variety of life including a vast diversity of dugongs, fish, dolphins, land mammals, and Crocodilians (when I say crocodilians, I mean the general group within the archosaur family that includes Crocodiles, Gavialoids, and Caimans). Image of Reconstruction of Lake Pebas Image Source: https://www.researchgate.net/figure/Palaeogeographical-model-of-northwestern-South-America-during-the-Middle-Miocene-some-14_fig6_254893768 While Crocodilian diversity decreased globally after the warm Paleocene and Eocene eras, emergence of the lake pebas system paved the way for an explosion in diversity for these semi-aquatic reptiles in Northern South America. This is best demonstrated by the vast and diverse Miocene crocodilian fossils found in the Urumaco Formation and Pebas Formation. https://www.sciencedirect.com/science/article/abs/pii/S0895981118303699 https://igeo.ufrj.br/inc/isc/3/3_87-Souza_Filho_etal_2020_Melanosuchus_latrubessei.pdf https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4375856/ These heyday for South American crocodilians saw the emergence of some of the largest aquatic crocodilians currently known on Earth since the Creteaceous and Paleocene eras, including Giant Caimans Purassaurus and Mourasuchus amazonensis. Image of Reconstructions of the sizes compared to an adult Human of several notable Crocodilians from Lake Pebas by Armin Reindl Image Source: https://www.deviantart.com/arminreindl/art/Crocodilians-of-the-Pebas-Megawetlands-900353328 The Lake Pebas system would persist up until the formation of the Andes Mountains during the Late Miocene. This decreased the size of the Pebas lake system and ultimately help give rise to one of the World’s most spectacular river systems, the Amazon. Crocodilian diversity in the region decreased as well and now only a few crocodilian genera inhabit South America currently. Lake Pebas is also the primary reason why the Amazon River system is home to freshwater stingrays, freshwater manatees, and freshwater dolphins. When Lake Pebas started to decrease in size, those creatures successfully adapted to the more freshwater environments of the Amazon River. Here's a list of all the currently known crocodilian genera and species that lived in the Miocene Lake Pebas system. If I forget any examples, please let me know and I'll add the examples to the list promptly. Unnamed Paleosuchus sp.

  4. On the night September 2, 2018, a large fire ripped through the prestigious National Museum of Brazil. By the time it was put out, a plethora of precious artifacts, including many dinosaurs fossils (with still many to this day missing). Of the specimens currently missing since the fire - the Holotype of a small theropod dinosaur from the Albian Cretaceous of Brazil's Santana Formation named Santanaraptor placidus. Santanaraptor (Romualdo Member of the Santana Formation) (Early Albian, Cretaceous period 112.6-109.0 million years ago) Specimen: MN 4802-V (partial skeleton with preserved soft tissue) http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&collection_no=67712 What makes this dinosaur special is, according to recent studies from the 2010s, it is one of the only known Tyrannosauroidea dinosaurs from South America (along possibly with Mirischia). (Also, thanks @Troodon for letting me know about this phylogenetic chart) Source of info and chart: https://www.sciencedirect.com/science/article/abs/pii/S0031018218302566?via%3Dihub The paleontological significance of this specimen cannot be understated, but there is some hope the specimen survived the tragic fire (possibly in one of the museum's metal shelves). https://www.nature.com/articles/d41586-018-06192-9 It's been between 4 years since the fire and the specimen whereabouts are still unknown. Does anyone (ANYONE) know if the Santanaraptor specimen MN 4802-V survived the fire at the National Museum of Brazil and if the specimen is now safe?

  6. We see a steady stream of "petrified mushrooms" here on the forum. Mostly they are pseudo-fossils which are the result of pareidolia. Sometimes they have a more rational explanation being things like worn down rugose (horn) corals with the coral septa being mistaken for the gills of the mushroom cap. Mushrooms are of course the fruiting body of a fungus which are largely composed of water (85-95%). The remaining solids are a few percent proteins and a similar amount of carbohydrates with less than a percent of minerals. Contrast this with bone material that is around 60-70% calcium phosphate in the form of calcium hydroxyapatite which is embedded in a mesh of collagen protein. The much higher mineral content explains why bones are all we have of most fossil animals. Teeth tend to be around 89% calcium hydroxyapatite with smaller amounts of calcium carbonate (4%), calcium fluoride (2%) and a smidge of magnesium phosphate (1.5%). The hardness and mineralization of teeth is the reason why teeth are the best preserved and most common parts of animals to be found as fossils. Members bringing pseudo-fossil "petrified mushrooms" here for confirmation will sometimes point to other erroneously identified pseudo-fossils as proof that mushrooms often preserve this way in the fossil record. A paleobotanist friend of mine happened to mention a paper documenting the remarkable occurrence of an actual fossilized mushroom preserved under incredibly exceptional conditions. It is, at present, the only documented fossil mushroom (fruiting body) known that is not preserved as an inclusion in amber. Amber is well known for preserving soft tissues and in addition to lots of insects and a scattering of other small plant and animal matter there are a few amber-preserved mushrooms. In order to document the exceptional (at present--unique) occurrence of this fossilized mushroom I thought I'd archive this paper here so we might refer to it in the future when trying to apply scientific principles to future pseudo-fossil "petrified mushrooms". This is a very brief paper written with a minimum of technical jargon and contains some lovely imagery. Hope you enjoy reading about this rarity. Cheers. -Ken Heads et al. 2017.pdf

    Jaw from Santa Maria formation, Brazil

    Hello! A collector from Brazil has shown me this fossil. Any idea what this partial jaw could be? It is from Santa Maria formation, Brazil. I don't know if it could be from a Dinosaur... it seems too big to be from a prosauropod... Could it be theropod? Or maybe reptilian or synapsid? Thank you very much.

    Purchased fish fossil

    Hello everyone I was browsing on a well known online auction site a few nights ago and spotted this fish fossil. Thinking it looked interesting with a current low bid I put in a cheeky last second bid and got it. It was listed as 'prehistoric fish fossil, Sandstone, two halves' so that's not a lot of help in identification. Looking at the preservation before and after purchase I'm thinking it is from Brazil? Potentially the santana group? Preservation isn't preticualy great, especially around the head and it looks to have partially fell apart because of this I'm not sure of the identification. I'm thinking Rhacolepis? Mind you I could be completly barking up the wrong tree! All comments welcome.

    Damaged Plesiosaur Tooth

    First of all hiiiii this is my first post on this forum Soo, I live in germany and am doing some vacation on the beach rn. I found a guy selling gems and fossils. I bought this lil specimen. After I bought it he said its the most rare thing in his inventory lol. According to the guy the tooth is from a plesiosaur, unknown if there is more in the matrix(Atleast there are some shells but thats not the point of this post anyways.). All I got about where its from was "south brazil". Facts list: >Plesiosaur tooth presumably >partially damaged >From (southern) Brazil The measurement in the pictures is in cm. Id really appreciate if anyone could help me identify this one, already thanks in advance^^
  11. I got offered this piece and I would be happy if someone can give me any hint if its real and no restoration. Thanks.

    Unidentified Brazilian Fossil Fish

    Hey guys, I recently acquired this fossil fish from what seems to be the Araripe Basin/Santana formation of Brazil at a store here in Hamilton, Ontario. Can anyone identify it for me please?
  14. Hi guys, in my city of Hamilton, Ontario, there is a shop just a walk away from my house that is selling Vinctifer comptoni specimens. One of the specimens being sold right now i will post pics now. How much of this fossil is tampered or repaired? Im asking as I am not familiar with the Cretaceous Santana formation fossils and I know these fish fossils are sought after.

  18. You're not going to believe your eyes, but a new jaw-dropping paper is available online: de Souza GA, Soares MB, Weinschütz LC, Wilner E, Lopes RT, de Araújo OM, Kellner AW (2021). The first edentulous ceratosaur from South America. Scientific Reports 11 (1): Article number 22281. doi:10.1038/s41598-021-01312-4. The discovery of Berthasaura reveals that not all ceratosaurs from the Late Cretaceous had teeth, because the jaws of Berthasaura lacked teeth. The Asian elaphrosaurine Limusaurus is also toothless, but the Late Cretaceous age of Berthasaura shows that some toothless noasaurids survived into the Late Cretaceous. The recovery of Berthasaura in a basal position within Noasauridae rather in a derived position might be affected by the absence of foot bones in the holotype and the percentage of missing morphological data for Deltadromeus because Berthasaurus is younger than Deltadromeus and other members of Elaphrosaurinae.

    Fish from Brazil - Species?

    Hi gang, I attended the east coast mineral and fossil show this weekend and picked up a neat fish from Brazil for my collection. The dealer couldn’t remember the ID. It doesn’t appear to be Vinctifer Comptoni which is really the only fish I’m familiar with from that region. Can anyone help me with an ID? Thanks!

    Please Help ID fish with possible horn

    Hi forum ! Many thanks for accepting me and very glad to join Please help ID this fish. I have no any knowledge in fossils weight of rock 1795 gr. Length of rock 330 mm, width 109 mm, height 33mm, length of fish 287 mm ( without the possible horn with horn approx. 295 mm ) , height 82 mm. Please notice in the photo of the rock that I have poured water on it, the fish seems to have some kind of a horn in front of its head. Possible Creataceous period ? Origin: My father in merchant navy had bought it in Brazil Thanks for any answers

  23. Scientists campaign for the return of fossils from Ubirajara jubatus, the new Brazilian dinosaur –Science, ksuadmin. The Sentinel, University of Kansas, January 14, 2021 The paper, which has been "removed temporarily," is: Smyth, R.S., Martill, D.M., Frey, E., Rivera-Sylva, H.E. and Lenz, N., 2020. A maned theropod dinosaur from Gondwana with elaborate integumentary structures. Cretaceous Research, p.104686. There might be even more controversy: [dinosaur] The name 'Ubirajara' is not available - Dinosaur Mailing List Yours, Paul H.
  24. I recently inherited this fossil fish from my stepdad, who traded a pair of moccasins for it at a rock show in the 80s. The seller claimed it was from the Green River formation, but given the matrix, color, and three dimensionality I highly doubt that. A quick Google search leads me to believe it’s probably from the Santana formation in Brazil and possibly a Rhacolepis buccalis? I’m a geology student but living in invertebrate country I can’t say I know a lot about fish identification I’m happy to add more pictures as needed or provide what little info I can. Thanks in advance!

    New Abelisaurid from Brazil

    The attached paper describes a new Abelisaurid from the lower Cretaceous of Brazil: Spectrovenator ragei . Its a good paper to keep as a reference source when trying to identify material from other geographic areas like Morocco http://sciencepress.mnhn.fr/fr/periodiques/comptes-rendus-palevol/19/6
