  1. Found this here in western Colorado I have done some looking online closest thing i can find is fossil/petrified palm wood it would be from the Niobrara Formation, Smoky Hill Member and is Upper/Late Cretaceous. What do you guys think? Did a quick polish too quick as you can see all the scratches haha Thanks anyone that can help
  2. Fossilized juniper?

    This was excavated at Baculite Mesa in Pueblo CO a few years ago. We were given a possible identification of it being a fossilized juniper. Any other input or verification would be appreciated. Thanks in advance!
  3. Found in Pueblo CO

    This piece was excavated from the Fountain Creek on the north side of Pueblo, CO. It was stockpiled in another area of town and my husband brought it home to me. It is so interesting! I think it is some kind of a fossilized plant from the prehistoric ages. Any ideas out there?
  4. Is this a egg?

    Hi there, so I came across this rock awhile ago. I found it in the mountains just west of fort Collins, co. I've spent a lot of time trying to find information on it but not having much luck. It's pretty hard, doesn't leave a streak and has weird layers. It's around 2 inches or so and round-ish. Hope the pictures are good enough. If not, I can always take more. Thank you for any info!

  17. I have researched for a while now on these bones i have in my collection and only thing i can find that is pretty close to what i have are sauropod metatarsals. Can anybody maybe confirm this or what they may be from? The 3D models are very accurate i put the measurements on the 3d models just click on the annotations. They are from the morrison formation here in Colorado, thanks to anybody that can help! 1st bone: 2nd bone:
  18. Douglas Pass, Colorado Finds

    My partner and I visited Douglas Pass, Colorado last August: Eocene, Green River Formation, Parachute Member. The site represents a very shallow lake bed and is known primarily for fossil plants and insects. Recently I unwrapped her finds. The first one I think is some type of fossil seed. It is about a half inch long. The second, I think is a partial insect larvae, about an 8th of an inch. Let me know what you think. Thanks.
  19. old colorado fossil site

    As a young kid - in the late 60s - we went fossil collecting not too far from Denver (where my parent's friends lived). I think we paid but I always thought it was a state park or something. I collected fossil leaves like the attached. Does anyone know the spot? Thanks
  20. Coloradan shark tooth id

    Greetings, I am an amateur fossil collector and rock hound and I don’t know too much about fossil species or how to identify them... My dad recently gave me some of his shark teeth he found in the 90s at his coworkers ranch. He never bothered to identify them so I’m hoping to get some help with that, thank you! He showed me the area on a map and told me about the rock types and I’ve come to the conclusion that they were found somewhere in between the Carlisle shale and the Niobrara Formation, though I could be mistaken. The area he found them at is southeast of Colorado Springs on private land. I will post pictures below, help of any kind is appreciated!
  21. Found this piece while walking on a newly excavated (6-8 inches deep) plains path about 30 miles southeast of Boulder, Colorado. I'm new to the area and trying to ramp-up on the geology and fossils with limited background knowledge but much time being retired. Overwhelming and fascinating! Several hikes to Dinosaur Ridge and Dr. Bakker's museum in Morrison. To my untrained eye it looks like a rib or similar flat bone piece. The dark interior color and texture seem somewhat "different" (?).
  22. Teacher's Fossil ID

    Hey everyone, today I was speaking with a teacher this afternoon at school and being the well known fossil enthusiast that I am, she brought up that she had found some plant fossils on her in-laws ranch in Colorado. She told me that the ranch was northwest of Denver but could not remember what town or county specifically. When I saw it, I thought it could be from the Cretaceous period Dakota Sandstone as I believe that it extends into Colorado, however I could certainly be wrong and it could be younger or older. I want to know what you all think. If I need more photos and want me to try to get more details let me know.
