  1. Fish ID

    Ok fish friends, I need some help on an ID. This fish is from Ciudad Cerralvo, Mexico (east of Monterrey). Based on the geologic maps, it could be late Maastrichtian. It has an overall feel of Pachyrhizodus minimus to me but I’m hoping for another opinion.
  2. Garfish from Jurassic of Mexico

    The earliest know lepisosteoid from the Jurassic of Mexico is presented in this paper. Nhanulepisosteus mexicanus was discovered in the Sabinal Formation in the town of Tlaxiaco, Oaxaca, southern Mexico. https://www.nature.com/articles/s41598-017-17984-whttps://www.nature.com/articles/s41598-017-17984-w

  4. Hello everyone, I'd like to share my extreme budget collection of exotic megs/shark teeth so far, I've have been collecting shark teeth and other for a little over a year and a half now on an extremely tight budget and have been surprised by what I was able to get a hold of so far. Condition doesn't bother me hence the budget but I have been able to find some megs from from interesting locations over the short period of time I've been collecting with a little bit of luck. Locations include Puerto Rico, Cuba, Japan, Hawaii, Morocco, Mexico, Peru, and The Phillipines. I estimate I spent no more than $430 in total for this small collection. Anyone else out there with extreme budget rare finds especially shark teeth (or from generally exotic locations), feel free to share and I'd love to see! In order of pictures: 1) Two megs and a hemi from Isabella, Puerto Rico 2) meg from Hawaii (Restored) 3) great white from Japan 4) meg from Morocco 5) meg from Cuba (unfortunately stuck on a wood plate but still a lovely display piece) 6) meg from the Phillipines 7) cubutensis from Peru 8) 2 Makos from Mexico 9 & 10) Heavily and horribly restored 5.9 inch Chilean meg (funny story with this one had an even worse restoration on it with made it look no different from a replica, was suspicious and bought it and when attempting a horrible derestoration process and a few slight touch ups of my own a large chilean meg was hiding under the mess, still needs a tad bit of work but I still love I was able to snag a large one cheap in this day and age ) @WhodamanHD Here we go uploaded !
  5. Microfossils

    I'm currently working on an oil rig in the Bay Of Campeche off the coast of Mexico. We currently have 5 paleontologist on board sampling micro fossils that are brought up when drilling. I had a chance today to look at some amazing specimens under a microscope. I wish I had pics but cameras are banned here. I got to see many types of Foraminifera that resemble the ammonties I collect. They were quite impressed when I showed them some of my Cretaceous finds from NSR.
  6.

  7. This piece arrived by way of Copper Canyon in Chihuahua, Mexico. Its owner is inquiring if it's an authentic piece and the best way it could get appraised.
  8. Bone?????

    I bought this fossil. It came from the Taman group in San Luis Potosi, Mexico which is callovian to Tithonian in age. The fossil looks like bone. It is in an ammonite coquina. The ammonites look like Perisphinctes sp. It looks like a jaw. It has hollow cavities just like bone. Please help me Identify this. Photo of the specimen I circled the fossil
  9. Perisphinctes?

    This fossil is an Ammonite which I think is Perisphinctes. This fossil came from the santiago formation in San Luis Potosi, Mexico, which is middle Oxfordian.The sanTiago formation is below the Taman formation which is were the Ochetoceras came from. There has been fossil coming out of the formation which are Perisphinctes (Middle Oxfordian ammonite biostratigraphy of the Lower Santiago Formation at Taman, San Luis Potosi, Mexico — with notes on Mexico–Caribbean ochetoceratins) or Bioestratigrafía de amonitas del Oxfordiano medio de la parte basal de la Formación Santiago en Tamán, San Luis Potosí, México – con notas sobre ochetoceratinos de México y el Caribe, in Spanish. Here's photos of my specimen Close up of the fossil
  10. Ochetoceras

  11. Fossil or not?

    I found this fossil in Mexico. Specifically in Cerro de las mitras, Garcia Nuevo leon, Mexico. Cerro de las mitras is a mountain which has sediments from the Cretaceous period. I have found many other fossils there. But this one is special because I'm not even sure if it's a fossil. I found it 4 years ago. The fossil is dark in coloration and has line running. Is like an oval it runs all over the rock.The back
  12. What ammonite?

    I bought this ammonite in San luis potosi, Mexico. It comes from the geological formation of Taman. Which is late Tithonian- kimmeridgian in age. This ammonite looks weird!!! Can you'all help me identify the genus.
  13. Dinosaur bone from Mexico

    Last summer I bought this fossil from someone who said it was a dinosaur bone. He said it came from the mexican state of Coahuila from near saltillo. I told him that how he found it. He said you have to go out to the desert. The bone is polish. I think is is most likely from the Difunta group, and maybe Cerro del pueblo formation 72 million years ago. Several dinosaurs come from there, ex: Coahuilaceratops, Velafrons, Latirhinus. Tell me what you guys think about it!!!
  14. Is this an Oyster?

    I was in Monterrey mexico last summer and I was looking for fossils at cerro del las mitras. It's a mountain that is cretaceous in age. I think this fossil is either from the San felipe or mendez formation. The most unusual think is the green coloring!!!
  15. Alga fossil?

    Northwestern Mexico. I found this between a bunch of scattered rounded rocks. Is it mineral pattern or biological? http://imgur.com/Y8gUgAb http://imgur.com/13tHqnh http://imgur.com/c0TiaaB http://imgur.com/1lgRuwz http://imgur.com/MYswynK http://imgur.com/sXECyfZ http://imgur.com/5LlME1i http://imgur.com/LfqT50d http://imgur.com/nxJuT56 http://imgur.com/clCnKlH http://imgur.com/x2LSBAx http://imgur.com/GArJmvB http://imgur.com/zZ5Hphi http://imgur.com/hz0coEB http://imgur.com/HHQF3oZ http://imgur.com/0qphjps http://imgur.com/15yag7h
  16. Fossil sites in Mexico

    Hello fossil-hunters, My family and I might soon go to Mexico on a trip. We are probably going to stay in Puerto Aventuras, Quintana Roo (Yucatan peninsula). Do any of you know some good nearby fossil sites where we could hunt? Thanks in advance, Max
  17. Small Fossil sand dollars

    Hello all, I'm new here so don't know my way around very well. I'm looking for any information on these little sand dollars. Age, location, any help at all. All I was told is they are from Mexico. Thank you very much, Steve
  18. Fossilized Eggs?

    I found these three what I beleive are round fossils together in the middle of my ranch in northern Mexico, very close to the south texas border, I have previously found other fossils in the same area but all of them are shells or star fish fossils nothing like these I found. I know nothing about fossils and would like to know what these 3 spheres are....Thank you!
  19. Bone of Large bird of México

    What opinion do you have, is a large bird jaw or is another structure? It was found in tufa calcareous with river bivalves of the late Pliocene of north of Mexico.
  20. Hi, In the second installment of my collection, I´ll show the Gastropods....
  21. My Collection - Equinoids

    Well, Since I´m a new member, I´ll share with you over the month my little "Fossil Collection"... I´ve always loved fossils and near where I grew up in Mexico you find a lot of fossils... recently I came to Texas and living in Houston, 3 hours away from "fossil land in San Antonio or Dallas... To begin my echonids... only 3 pics to leave this as a brief post....
  22. Yucatan Fossils

    Merry Xmas and Happy New Year to all of our Fossil Friends! We took a December getaway trip to Mexico - our annual Yucatan vacation - no fossil hunting, but to my surprise, we did see a fossil sign and rock while doing a pedal-zipline through the canopy at a jungle theme park called Xel-Ha. You can see the fossil sign and a closeup of part of the rock face which has 67 million year old marine fossils - mostly coral and some shells. On previous trips we've seen some spectacular marine fossils on the roofs of caves we explored (mixed in with the bat colonies that live in the caves). Thought you might find this to be a fun and quirky trip report, in keeping with the holidays.
  23. An article (in German) about a hadrosaur graveyard in Mexico: http://www.weser-kurier.de/startseite_artikel,-Auf-den-Spuren-eines-Dinosaurier-Friedhofs-_arid,716919.html Judging from the article, I'd be curious to see if the hadrosaur skeletons are Magnapaulia or Velafrons.
