    red wood petrified forest

    From the album: fossil wood

    an incredible, 60 cm wood from the famous petrified forest, coming from an old collection
  4. I found lots of petrified wood in the lower part of the Miocene Chalk Canyon Formation north of Phoenix. The layer is mostly sandy and pumaceous. Does anyone know what the siliceous 1mm long elongated spheres are or how they formed? Could they be fecal pellets, fungi or other fossils. I have seen similar structures associated with California Miocene palm wood. @paleoflor Penny is 19 mm across.

    What kinds of fossils are these?

    I found these in the Huachuca Mountains of Arizona. Most are very small, about 1 cm each or less. A couple of them might be almost 2 cm across. Can anyone tell me what these fossils might be?
  6. Hope this isn’t inappropriate for this forum. For everyone who was following my excavations, Dr Klein presented his findings. Dr Lucas is coming back later this year to pick up a few more tons of my tracks.

    Sponge or coral?

    Hello, wondering if this is a fossilized sea sponge or coral? It is large and quite heavy. Found in the Coconino forest past Payson and Strawberry.
  8. Everyone I've encountered on this site has been very helpful, so thank you. However, I'm in need of more help. For the last year I've been collecting real fossils in the field and selling some to pay for more exotic rocks. In a recent post I found that my Solnhofen shrimp is, if not totally, mostly fake. Now I'm quite suspicious of my entire purchased collection and was hoping you could help me identify fakes. The first two pictures are apparently Priscacara, Green River Formation, Eocene; the next two supposedly Asteroidea, Morocco, Ordovician; the last three supposedly Triassic, Arizona petr

    Fossils or just neat rocks?

    Hello, apologies for opening a new thread. Are these just neat looking rocks or possible fossils? I could not tell.

    Fossilized shells?

    Hello, Over the years I have found several fossilized shells on the Mogollon Rim in Arizona. I was wondering if these can be identified?
  11. My 8yr old found this neat fossil and we could use some help with identification. He found it on the Bell Rock climb hike of Sedona Arizona. The fossil is slightly concave/curved. It's 4 cm long and about 2cm wide with some tapering. You can see three distinct tips on one end and is flat on the other. You all came through the last time so any leads would be immensely appreciated. My son is just dying to find out what it is he found.

    This specimen was found near the town of Mammoth, Arizona.

    Amphibian bones

    Been searching my upper level recently- Shinarump Formation, late Triassic. Finding some decent bone pieces. Most likely amphibian, particularly Metoposaurus.

    Found this North of Black Canyon City. There were numerous other fragments that were being exposed by erosion.

    Arizona Brachiopod? Indian Gardens Paleo Site

    Trying to Add IDs to our YT video and this one is not on the "ID Key" at the paleo site. I will include the ID Key for identification purposes, thanks in advance! GPS Coords: 34°19'21.3"N 111°06'26.2"W

    Plant material?

    On the back side of a plate I received recently containing Chirotherium barthii or Isochirotherium sp. prints from the Holbrook Member of the Moenkopi Formation, Snowflake Arizona, I found what might be plant material. I’m not sure if they can be identified as anything with these photos but I plan to take closer more detailed photos once I’m back home. Personally to me (which could just be my mind playing tricks on me) they seem to be stems of some sort. Before I conclude this post though I’d like to apologize for my past actions, since I’ve joined the forum in 2019 I’ve a

    Is this a fossil?

    Found near Canelo, AZ. The grey stone feels brittle, lightweight, and gritty. And there's tons of it around. I'm not sure if this is a fossil or not. Just thought it looked real curious. What do you guys think?

    Unknown fossils - Receptaculites?

    The two sides of a single small chunk of limestone show two very different fossils. One side may be a Receptaculites, and the other I don't recognize. The rock was found on the surface in an area of mixed cobble, formerly an ancient riverbed, so the origin is uncertain. Most of the old limestones in the area are Devonian or Carboniferous. The stone's about 4 cm long. The area it was found was also inhabited by the Sinagua people, who abandoned the site about 700 years ago. They could have transported the stone from somewhere or traded for it? Any ideas what th
  21. Found on Arizona mesa top. What’s curious is the shell like structure that I have not seen in the many geodes I’ve found around here. See 3rd and 4th pics for best outer shell view. Any thoughts from the community? Thanks
  22. After a one year off for Covid the Tucson show will open the last week of January. Here is a link that provides you info to the +40 venues. Arizona still has high daily Covid 19 cases, so some venues or dealer rooms may require you to wear a mask, be safe. https://xpopress.com/showcase/profile/1/tucson-gem-mineral-fossil-showcase Lots of major changes will occur this year with the location of fossil dealers. The Arizona Mineral & Fossil Show which occupied the Tucson City Center Hotel was moving to the El Conquistador Resort but their web site says this show
  23. Hello everyone, A while back I was gifted this fairly large piece of pet wood from Arizona. I don't really know what I can do with it as I don't have any equipment to polish or cut rocks like this. I was wondering if any TFF members have such equipment, and if they did how much it would cost to either polish this piece at one or both ends or alternatively, slab it and polish some of the slabs. I don't know if it would be worth the time or money to do so, I am just trying to see what I can do with a piece like this. Thank you very much for any help, Misha
  24. Hi All, so I had heard about fossilized coral located in the Western Arizona desert near the Colorado River. So we went out there and did some rock prospecting ourselves. The location is La Paz, County south of Parker, Arizona. Namely, the terminal moraine-like hills about 10 miles south-east of Parker, Arizona beyond the Colorado River Indian Reservation. We found a ton of very interesting sponge or coral-like rocks on top of these hills. So this is consistent with a few other reports online about this. First, let me describe this location as it’s somewhat fascinating if you p
