  1. I recently bought a ranch in Pueblo,Colorado. It has some big drainages going threw it, whare I can see many layers. I've already found tons of shells in almost every rock and one Snell shell. What can I expect to find if I'm lucky?
  2. Another found in So. Colorado

    After reviewing some of the identified fossils on this site, I think I may have a trace fossil..? But on the opposite side if this rock is another impression of a round “shell.” This was found in Southern Colorado. Any idea what the small shell-shape is in my second photo?
  3. Found in So. Colorado

    I’m hoping to get help identifying these fossils found over the weekend in Southern Colorado in shale-like terrain. Hard to tell from the photo, but the smaller one has the same type of pattern. Thanks!

  5. Greetings from Peyton, Co

    Greetings from Peyton, Co! Semi new to the state and definitely new to fossil hunting. I look forward to learning from y’all. On a recent camping trip to Pueblo, Co I found a a few more, and way more detailed fossils. The shell is beautiful, but I’m particularly curious what animal the long bone with a single tooth may have come from. Any ideas? Many thanks!
  6. Went up to Douglas Pass, Colorado today for a hike with my wife. I have always hunted for fossils at the Radar Dome location. Today we decided to scout around for another location to collect. Hiked up a very steep hill to a shale exposure and found this larvae after only 1 minute of looking. We had not come prepared today to collect anything. Will probably head back up next weekend. The larvae is approx 2.25 cm across. There are also some parts of other larvae on the piece.
  7. Ornithomimus claw?

    Doesnt look it at to me, no groove which seems to be on others, but most online are hand claws. But could be a very worn one? Or something else.
  8. burrow.jpg

    From the album Mancos Shale - Grand Junction, CO

    Marine burrow. Found this down in the Mancos shale, loose. Possibly from the overlying Mesaverde formation. I have seen many burrows in the Mesaverde sandstone.
  9. Allosaurus tooth is it real?

    Hey guys, I bought this on online at an auction for reasonable price, which seemed quite cheap for an allosaurus tooth. The seller wasn’t really sure if this was an allosaurus tooth or not, it was his best guess please tell me what you think.
  10. Dinosaur Bone

    My family owned private land near garden park in Canon City, Colorado. This is a couple of pieces that were found there. I'm just curious on what body part they may be.

  12. Colorado is giving up the goods.

    One of the great things about being a geologist in Colorado is that I get to see a lot of places most people don't. How I see it, when I'm not in the office...and trust me there is more armchair time than there is field time, but when I'm not in the office, I'm being paid to scout new fossil locations. The company is just lucky I have a GPS in my company truck! But to be honest, they are totally cool with me taking detours...I digress. One day I was driving to BFE for work, and noticed something beautiful in the background. I thought to myself, that looks deliciously fossiliferous. It took a bit of leg work and schmoozing, but I was able to gain access to this parcel of land. My initial thoughts and research were correct, we immediately began to find chunks of fossilized bone. Soon, we had found a large portion of Oligiocene turtle. We could only spend a few hours there the first day, but at least now I knew I was on to something HOT. Being the awesome, handsome, and extremely nice guy that I am, I offered to take a number of colleagues out for fossil hunting. I work with a million geologists, and the odd thing about geologists is that most of them are only into minerals, not fossils(lucky for me) Two of my closer friends accepted the offer, and we were off! It wasn't long before one found a large portion of tortoise shell and the other an oreodont jaw. I only found a bison But it is fine, I spent most of my time helping those guys extract and preserve their finds. To be honest, I was treating it like another scouting trip. Anyway, I'm currently prepping the tortoise, and have already prepped the jaw. As soon as the snows fully melt, I will have my hands full. I'm super stoked about this location. Here are some pics. HH all. -J
  13. Quick fossil jaw id

    Hey everyone! Sorry I’ve been absent from the forums lately. Been doing the geology gig and found a new fossil spot near home. white river formation-what’s the jaw? Any ideas? I’m not used to these western fossils!
  14. 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
  15. 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!
  16. 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?
  17. 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!
