  1. Hey Folks, my presence has been a little light on here lately, I have been hanging around in TFF facebook as an admin and working on furthering my nascent paleo career. I hope you are all doing well, I certainly miss all my forum friends! I have been doing a little side project for a few months: writing Wikipedia pages for fossil Cartilaginous fish. It's one little way I can give back to the fossil community, so the next curious person doesn't have to go through the trouble of finding and accessing references and distilling information for obscure species as I have. It's also a task I find a little mindless and relaxing. Anyway, one problem I consistently run across is a lack of usable photos. While not strictly necessary, I think it is helpful to have a visual aid. Up until now, I have gone down the list alphabetically and contacted people to get pictures of teeth, but this is extremely tedious and I don't always get responses. So, I have a humble request! If you have shark or ray teeth from species or genera which do not yet have a picture and/or page on Wikipedia and you would be fine with it being used on one, upload a picture to Wikimedia Commons or post it in this thread and I can upload it. If you chose the former, let me know here so I can write a page on it or insert it into the proper article. If you chose the latter, it will be under my name (Mason Hintermeister) but I can credit you in the description. If you'd like me to do so, let me know what name you'd like to be credited as (You can PM me this information if you like). If you have fossils of species and genera which don't have Wikipedia pages which are not cartilaginous fish, I can upload them too and maybe even write a page for them. I'm not expecting a ton of responses here, but I like to think every new page and picture helps. Photographs are usually under a CC BY-SA 4.0 license, a fancy way of saying the photograph is usable by anyone provided they link the citation and they do not alter the photograph. If you upload it yourself, you have other options and if you have me upload it and you would like to use a different option just let me know. Thanks in advance!
  2. So, I know fossils are largely replaced by minerals which turn them to stone in the shape of the original (bone, tooth, whatever). But do some minerals survive? For instance, does the original calcium in the tooth or bone remain? What percent of a fossil would you guess is original mineral vs replaced mineral?
  3. Is this a Fossil?

    Greetings all, first post! So I found this bone in the Olentangy River (Columbus, Ohio) the other day, sort of looked out of place? It passed the flame test, is it a fossil?
  4. Theres no way I'm the only one, but I think a fossil display with models incorporated take display and immersion to the next level. The creature alongside the evidence it left behind, makes such museum like feel in appearance and enhances the appreciation and wonder. Heres a thread to post any fossils you have on display alongside a model, statue, or toy. Here is a display from my collection of one of my favorite prehistoric creatures postosuchus alongside a giant 10inch+ chirotherium pos/neg footprint.
  5. Hello let me start of by say you all are awesome! Amateurs like myself have got a lot more confidence because of the help you give us. It was great day when I discovered this site I had bought these a ways back and I was going thru my collection and it would be great to get an opinion if I these are what they were described as. The "raptor claw" was the first ever fossil I bought! (Fingers crossed haha) The COA said it was from the Taquiz, kasar-es-souk, region in Morocco. I believe the seller told be the red lines we blood grooves? It was probably 10 years ago so I dont recall much else about the ad. The other two were bought from the same seller, who did not have much reviews so I took a chance I guess. He described them as a "tricertops frill spike" and an "ankylosaurus armor scute" all i have regarding these ones is that is was found on private land in Wyoming in Lance creek formation... Any input would be greatly appreciated! I tried to follow the posting etiquette sorry If I missed something. Thank you!
  6. Tyrannosaurus rex or nano femur??

    Hi there! I recently purchased this online, could you please help identify this? the seller was unsure if it was a juvenile trex or a nano. It was found in Hell creek dawson County east of Glendive Montana Thank you :)
  7. Hi everyone, I am a double national from Mexico/Canada, and I travel occasionally between both countries. In my time here in Canada I have started a small fossil collection- three sliced ammonites, three cheap trilobites, a Crinoid plate, a 3.5 inch Megalodon tooth, a piece of ammolite and another gemstone. All of these are relatively small in the 1-3 inch range, with the exception of one of the sliced ammonites being 5 inches. I do not have a trip to Mexico planned solidly but I am considering going back eventually once COVID starts slowing down, and I will bring my fossil collection with me. I know and have read that I will likely have no trouble getting them into the plane in Canada as carry-on luggage save for a few inquisitive questions from airport security, but my big concern is once I arrive at Mexico. Customs in Mexico City can check your baggage on arrival before you exit the airport terminal. A few years ago on a return trip to there, I had brought a small dead branch that was curiously shaped like a hand, a customs officer picked it from my carry-on luggage and promptly destroyed it and put it in a trash bin. I have tried searching on the web for whether or not it is legal to bring fossils to Mexico, but the information is either inexistent, vague, or conflicting. I have read that it is illegal to bring them OUT, as all Mexican fossils are considered cultural heritage and thus cannot be removed from the country, but bringing them IN is my concern- would they get seized by customs, or even destroyed by a careless customs official who thinks these million-year-old dead animals or the soil they are found in are bad? Any help or knowledge on this subject would be appreciated. A thread here I previously found:
  8. One night recently I was hiking with one of those high powered spot light apparatus on my head and while looking down I noticed this specimen. Not sure if its a fossil or from what type of creature it came from but it definitely struck me as quite interesting and out of place. Does anyone have any idea what this could be?
  9. Another auction find

    This one was pretty cool too:
  10. Real T.Rex tooth?

    What do you think? This tooth is 3 inches long. It was found in private land in Wyoming, Hell Creek Formation
  11. Hi! My son found this at Fossil Beach on the Potomac River at Westmoreland State Park, VA. I was hoping someone could tell me what it is. He is an aspiring (seven-year-old) paleontologist and very excited about his find! Thanks for your help!
  12. Hi there I've always wanted a sabertooth skull, and for the past year i see many coming the same seller among other fossils from our favorite auction site. They never really explain how much of the skull, eggs, pssitacosaurus, is authentic and not responded to messages. Do you recommend these products? Thanks!
  13. HI all, Hope everyone has been ok in this crazy year. We were able to self isolate (by about 20 miles) this summer and visited our favourite spot for a bit of fossil hunting near Princeton in South-West B.C. Canada. Our site is near the ghost town of Blakeburn, which can be a neat diversion when you need to take a break from staring at rocks all day. Here are pics of some of the finds from 2020. Pics aren't the best, finds are very small - my hubby has very sharp eyes!! Enjoy!
  14. Potential fossil sites

    I have been doing some Google maps searching for sites that may yield a fossil or two. I found a few sites that look to me to have potential. Fortunately they are close to my house. I put the coordinates into my marine GPS and I am prepared to go take a look. What is your perception of these Google images from a fossil potential perspective?
  15. Identerfiying this tube fossil

    Some of the fossils my son found amongst road base material. All are straight tube shapes in various sizes. I have sanded one as a cross section to show the pattern. Found in New South Wales, Australia.
  16. Flowrock with a fossil

    I think I finally found a fossil within a piece of flowrock!?!?!? Found in the same area as the other flowrock pieces in N central Ohio, in a river. Nothing superb but I’m excited! Looks like a shell to me- right? Thanks!
  17. Hi everyone this is matt again check out this worm trace fossil I found in the creek today here is a photo
  18. Hey guys, I just posted a video where I find some huge verts from an Ichthyosaur (towards the end of the video) They're the biggest articulated backbones that i've found!
  19. Latest project

    From the album Winter Hobby

    This has become very addicting. I've been using an art gum eraser with a bit of success. I'm hearing that a micro abrasion tool is the next "tool" to invest in if I want to take this to the next level. They seem a bit pricy and cumbersome. Any thoughts?
  20. baby dino fossil?

    a friend of mine showed this to me and i thought it was fascinating we think it might be a type of flying dinosaur?
  21. Bone or Sandstone with shell bits

    Found in clay soil, Cerritos, California.
  22. fossilized Jaw

    I may be wrong but looks like some sort of jaw, can someone identify it?. its around 10 inches long.
  23. Found in New Mexico on private property, not far from Morrison Formation...Circled in red highlighter is what appears to be a talon...last photo is of the opposite side..
  24. My crinoid fossils

    Species: Cyathocrinites kelloggi & Macrocrinus mundulus Age: Carboniferous (Mississippian) Location: Witherspoon Quarry, Crawfordsville, Indiana Formation: Ramp Creek Limestone Size: Cythocrinites 2.6"
  25. I recently acquired a very large lot of petrified wood from a very old home site that was likely collected from the Douglas County Colorado area. Probably from the surrounding area of the home, which dated back to the late 1800's. Among the pieces were a few that did not look like wood, and one in particular that seemed very unique. I included one picture further back for scale sitting on the back of my truck. It is pretty heavy maybe 35-35 pounds. Any idea?
