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!

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" (?).

Greetings! I am new in the forum, located in Monument Colorado (Colorado Springs). I have looked through the forum and see a lot of great stuff!

Hello! Thanks for allowing me to join this forum. I am a rock enthusiast and being here in Pueblo, my husband and I come upon many rocks and things that we aren't able to identify. Any input is always appreciated as I share a couple of treasures we have. Thank you!

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.

Hello all- I found this in NW Colorado (Moffat County) this past summer and can't seem to nail down what it is (I am a total hack of a rock hound). Some sort of chalcedony?

I have been involved in a post "Florissant Fossil Quarry Fun". To make a long story short, I took the advice given to preserve my specimens from Florissant. Unfortunately some of my specimens had already broke. So I took out my razor blade and split them further. To my surprise, I think I found 2 insects!!! Your thoughts?

I found this bone near a very old gravesite in the Colorado Rockies many years ago. Not sure if it's human. It's old though.

Here is another one of my finds. I was out on a Hunting trip in the Rocky Mountain range and stumbled upon this beauty in the middle of a recent burn area. This was a piece that was a part of a much larger rock. It was mixed with quartz crystal. I was lucky to find a piece broken off. The piece I have is about the size of a small bowling ball. My thoughts are burned petrified wood. The black is almost like black quartz embedded in other rock.

Hello, I am completely new to this forum as well as posting anything to do with fossils. I am no expert by any means but I do have a knack for finding fossils. I’ve found so many over my life that I just collect them and hope that one day I’ll find someone who can identify my collection. I have mostly shells and corals. I’ll post my photos over time. Happy hunting!

Agatized and found amongst dinosaur fossils (looks like a "brain")
GrandJunction posted a topic in Fossil ID
I put "brain" in quotes because I obviously know it isn't one, but helps describe its physical appearance. Although, maybe it is??? Lol. No idea what this might be. Found on my ranchland, western Colorado, amongst other dinosaur fossils on the surface. Appears to be agatized. It's in the shape that I found it and assume the entire piece would be a sphere. I was thinking some sort of coral, but due to the other dinosaur fossils in the immediate area, I'm wondering if it might be something dinosaur related. Pictures taken wet. Any guesses? Thanks.thumb.jpg.195740e320670aad62f1447f592b6b5c.jpg)

Hello everyone! My wife and I have been fossil hunting for a few years, so were still fairly new, but we have an amazing area at our doorstep. Hopefully we can find some amazing stuff to share with you all, and learn some things along the way.

Found this a couple days ago on my ranch. Western Colorado - Morrison Formation. On the surface. No prep besides light brushing. I'm not that knowledgeable, but could this be a clutch of small dinosaur or other ancient reptile eggs? Lots of dinosaur activity in the area. Probably about 20 eggs total including what isn't visible in the middle. 105g total weight. They measure roughly 1/2 inch or 1.25cm each. Larger pics included in link. Thank you https://postimg.cc/gallery/nni2692y/508eae1d/

Greetings! I'm new on here. This came from my Father who was a rock hound and traveled to Colorado every year. I inherited this and have no idea what it is. Can anyone help? (3 lbs 4 oz, 4 1/2" x 4 1/2".) Thank You! Sherri

Not sure what this could be. Appears to be some type of fossil with cell structure. Found it walking my property in western Colorado - Morrison Formation. No preparation done besides rinsing in water and a light brushing. Full size images in link. https://postimg.cc/gallery/2c94nahdm/565295ef/ Please let me know your thoughts. Much appreciated.

I found this sandstone slab on our property in south west Colorado, near Placerville, and was struck by the spider like creature especially. There also seems to be a mollusk nearby this creature. But its legs would have been so fragile, hard to imagine how it could be a fossil. But it doesn't seem like just a random shape to me. Any thoughts? I had to reduce the pictures quite a bit to fit size requirements here.

After practically years of scouting properties in my area, I’ve finally found a decently productive site. To start, will just be some neat info about the site.

Here’s one a friend and I have been trying to settle for a little while. One end of the argument is that this is an unusual rock carried off the mountains by glaciers. the other end is that this is a heavily eroded bivalve.
