  9. Help to ID

    Friends, this time I seek the help of a connoisseur of fossil corals, they are from the Neocomiano (Lower Cretaceous), from a town near Tehuacán, in the State of Puebla (Mexico). The scale is in centimeters. I appreciate your help because although I have dedicated myself to reading the scientific literature of the area, I am an amateur, and many of them are very similar. Of those who have an idea, I put their name for them to say. regards
  10. Stalactite

    I purchased this in Mexico legally many years ago. It was brought back through customs and inspected. Is this a stalactite and is there anyway to know it’s approximate age? Thank you.
  11. A new paper regarding toothed mysticetes is available online: Azucena Solis-Añorve; Gerardo González-Barba; René Hernández-Rivera (2019). "Description of a new toothed mysticete from the Late Oligocene of San Juan de La Costa, B.C.S., México". Journal of South American Earth Sciences. in press. doi:10.1016/j.jsames.2018.11.015. Niparajacetus is the second Oligocene mysticete to be described from Mexico and the southernmost occurrence of an aetiocetid-like mysticete from the Pacific Coast. I wanted to see if anyone has a copy of the this paper because there's no free access at the website for this paper.
  12. Help ID Ammonites from Mexico

    Friends, I seek help to classify them, I have acquired them over the years without any reference. What I have been able to investigate is that they are from the Kimmeridgiano-Portlandian, probably from the formation "cañon of las lajas" (San Luis Potosí, Mexico) .I look for your name and surname.
  13. First Parkosaurus EVER Found In Mexico!!!!!!!!!!!!!!!

    https://mexiconewsdaily.com/news/parkosaurus-fossils-are-first-ever-seen-in-mexico/
  14. Hi there. I found this several years ago in Tamaulipas, Mexico. I guess it’s a tooth of a a mammal... but I don’t have the slight lest idea.
  15. A new mysticete-related paper is available online: Hernández Cisneros, Atzcalli Ehécatl. 2018. A new group of late Oligocene mysticetes from México. Palaeontologia Electronica 21.1.7A 1-30. https://doi.org/10.26879/746 palaeo-electronica.org/content/2018/2147-oligocene-mysticetes-from-mexico The discovery of Tlaxcallicetus represents the second named species of Oligocene chaeomysticete from the eastern Pacific and only the third named species of Paleogene mysticete from that region, the other being the late Eocene Mystacodon from Peru. Thanks to the discovery of Sitsqwayk from Washington State, Tlaxcallicetus shows how much more is to be learned about early chaeomysticete diversity in the Pacific because the vast majority of Pacific chaeomysticetes from the Oligocene have been found in New Zealand (it's possible that there may be an undescribed Oligocene mysticete fossil in museum collections in California, or mysticetes preferred pelagic habitats in California in contrast to the Pyramid Hill odontocetes).

  18. 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.

  21. 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 !
  22. 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.
