    Saltasaurus tooth ?

    Hello, i saw this sauropod tooth labeled as a Saltasaurus tooth from argentina for sale today. Sadly those are the only pictures i have of it. Can someone identify it ? Are sauropod teeth from argentina hard to get ?
  2. Between the weather and my busy schedule, I haven't been able to get out into the field, so I have been fossil-hunting in my mailbox. I bought a small collection of pieces that was something of a mish-mash. The labeling sucks. Some of the labels are missing and some are mixed up. This tooth did not have a label. It was mixed in with dinosaur material, including a sauropod eggshell fragment from South America, some hadrosaur bone fragments from the western US, and some Moroccan fossils. I don't know where this piece came from - it could be Morocco, it could be South America, it could be the US, or..... It measures 50mm long x 11mm wide at the base. It doesn't appear to be glued or repaired, but looks like it was sealed with some kind of butvar or poly. Does anyone know what critter this tooth is from? Any help would be greatly appreciated. Thanks in advance! MikeG

  4. Long-necked dinosaur fossil found by Argentine scientists is one of biggest ever By Lucila Sigal, Reuters, May 18, 2023 The paper is: Agnolin, F.L., Riga, B.J.G., Rolando, A.M.A., Rozadilla, S., Motta, M.J., Chimento, N.R. and Novas, F.E., 2023. A new giant titanosaur (Dinosauria, Sauropoda) from the Upper Cretaceous of Northwestern Patagonia, Argentina. Cretaceous Research, 146, no. 105487. It has a "a femoral total length of about 1.9 m long." Yours, Paul H.
  5. Claimed to be from the Cretaceous of Argentina. Dimensions are 30 * 29 * 6 mm. No additional information provided. Thoughts?
  6. This fish has been known for decades among collectors as "Argentina sphyraena" and has only recently been described as Surlykus longigracilis. It is the most abundant fish from the Eocene Fur Formation of Denmark. Etymology: Genus named in honor of professor emeritus Finn Surlyk, The species name is derived from the Latin words ‘longus’ (long) and ‘gracilis’ (slender) referring to the body shape. References: Schrøder, A.E. & Carnevale, G. (2023). The argentiniform Surlykus longigracilis gen. et sp. nov., the most abundant fish from the Eocene Fur Formation of Denmark. Bulletin of the Geological Society of Denmark, Vol. 72, pp. 1–18. ISSN 2245-7070. https://doi.org/10.37570/bgsd-2023-72-01.
  7. Recently I found a really interesting article rom 2021 describing fossilized specimens (in the form of teeth) of the giant shark Carcharocles (Otodus) megalodon from Buenos Aires Province, Argentina. Here is the article: De Pasqua, J., Agnolin, F., Rolando, A. M., Bogan, S., & Gambetta, D. (2021). First occurrence of the giant shark Carcharocles Megalodon (Agassiz, 1843) (Lamniformes; Otodontidae) at Buenos Aires Province, Argentina. Revista Brasileira De Paleontologia, 24(2), 141–148. https://doi.org/10.4072/rbp.2021.2.05 https://www.researchgate.net/publication/354201776_First_occurrence_of_the_giant_shark_Carcharocles_megalodon_Agassiz_1843_Lamniformes_Otodontidae_at_Buenos_Aires_Province_Argentina What really actually baffled me was the age the scientists who authored the paper assigned to the specimens. The specimen MMDA-1 was found close to the Atlantic coast in sedimentary deposits consisting of five depositional sequences (DS) dating between the Miocene and early Pleistocene eras. The authors state its possible the specimen came from DS5 or DS4, which date between the late Pilocene-early Pleistocene eras. If this is correct, this would make this incredible find even more incredible as it would represent the youngest known Carcharocles (Otodus) megaldon fossils (and no, I'm definitely not counting the HMS Challenger specimens as it's pretty much been confirmed those specimens are much much older than several thousand years old). Also, this is not potential proof C. megalodon survived into the Holocene! Though, I'm am a bit skeptical about the age give it was found in a pretty loose sedimentary deposit by the coast! What do you guys think? Do you think specimen MMDA-1 could be from the late Pilocene-early Pleistocene or do you think it could be older?

  10. I decided to make a short video of my fossil pine cones from Argentina and did some research to get information so that in the video it would sound like I know what I'm doing. That didnt work too well. I could only find info on the Araucaria pine cones. By any chance would any of you smart folks know what these other cones are. I really need some help with these. Thank you so much. RB

  16. This Fossil came from the south coast of Buenos Aires in Argentina. The zone was formed 10,000 years ago during the last ice age. (NOTE!) this is not my fossil
  17. Hi everyone, I was recently offered this Giganotosaurus tooth. I was wondering if there was a way to distinguish it from carcharodontosaurus teeth from the kem kem beds? Or if anyone can share there opinion on this one, thank you.

    New Abelisaurid from Argentina

    Looks like Abelisaurid week in south america A new Abelisaurid is described here from the late Cretaceous of Argentina : Niebla antiqua For those collectors that have abelisaurid teeth from Argentina this species just adds to the complexity in trying to identify isolated teeth unfortunately its paywalled https://www.sciencedirect.com/science/article/abs/pii/S0895981120304582 Got some better photos

  24. Interesting discovery of a new theropod in South America: Overoraptor Chimentoi. Thought to be closely related to 'Rahonavis' from Madagascar; “...........would indicate that Overoraptor chimentoi and Rahonavis could form a new group of paravian runners, which would be closer to the birds than known raptor families.” http://www.sci-news.com/paleontology/overoraptor-chimentoi-08517.html
