Hi there, We recently moved to the Colorado Front Range from Michigan. We’re used to hunting for petoskey stones on the Great Lakes. Here are some of our new CO finds and we’d really appreciate any information! thank you so much! We are so excited for this new land to experience.

Hi Everyone! My family and I are going on a trip to North Colorado this August and I really want to collect and keep some dinosaur fossils while I'm there. Does anyone know of a program, charter, or guide who can help me? It doesn't have to be in Colorado, I'm close enough to Wyoming that that is also an option. I tried looking for something on my own and all I can find is either parks where collecting is forbidden or what is basically "pay us two grand to be our field slave for a week".

Out walking near Denver CO today and stumbled across what looks to be a large tooth. Can anyone help me understand what it might have come from?

I found an interesting fossil in my Mesaverde formation matrix yesterday. It has me scratching my head a bit. At first I thought it was a Sawfish rostral but after a bit of research I am not sure. I think it looks like Cretamanta possibly. It is the right size at 1mm. I had had some difficulties with the equipment at work today so I only got one decent picture.

This apparently came from dinosaur monument in Colorado. Are the dark areas bone fragments?
-
These will all be from the Mesaverde Formation, Colorado. First up is a 1mm tooth that sure looks like an anterior Heterodontus tooth to me. I am open to any ID suggestions but I see a lot of similarities with the Atco tooth I recently found.

I have here a theropod tooth tip from the Morrison Formation of Moffat County, Colorado. It's 1/2". The claim is that it's Torvosaurus based on the serrations. Is that a definitive way to identify this as Torvosaurus as opposed to another theropod? @Troodon Thank you, Bellamy

I have been a little bored lately and missing micro matrix searches. It’s been awhile since I’ve gotten to enjoy hunting for tiny shark teeth. I got some more matrix from the Rollins Member of the Mesaverde Formation. My first time through that matrix produced one of my favorite finds, a 1mm Scyliorhinus tooth. This formation doesn’t provide much in the way of complete teeth but it is a fauna that was really quite diverse. The first search was with less matrix but I found enough to want to do it again. This time I have more matrix and in varying states. Some is broken down, some is in small matrix bits and we have a small piece of untouched matrix. It’s a good chance to practice breaking matrix down and learning a broader approach to collecting. The first search of the broken down matrix and first look at the small bits has yielded few complete teeth but a much wider diversity which makes it fascinating. The first Squalicorax, Ptychodus, Lissodus, and Rhinobatos. It also produced an Orectolobiformes that doesn’t appear to be Chiloscyllium. It looks much more similar to Restesia. I am really looking forward to searching more as the breakdown goes forward. I am going to take closer pictures tomorrow but the first time finds are among the teeth in this picture.

I found this on my place which makes no sense. I'm on a whitewater mountain river with gravel, rocks, boulders (granite). Most non-granite rock comes down from above and it's worn. This doesn't appear to be river-tumbled. The thing in it caught my eye and reminds me of wood but I'm not sure. Any ideas?
-
I'm thinking on a trip to a spot where I saw a bunch of sea shells south west of La Junta, Colorado. I'll be prying rock layers apart looking for stuff that strikes my eye. However, is there anything in particular I should be looking for that would be a real score? I think the picture is the stuff if I have my dates right. Thanks.

I know there is not enough to ID but thought I'd share. I used to hike the oil shale cliffs behind the Job Corps Center out of Colbran, Colorado, back in the 70s. The size of the scales on this fish were such that I knew it would be a keeper if I caught it. The oil shale there is such that you can actually light it and it burns. (The little one on the right I found out of Eden, Wyoming, sometime in the 80s).

Hi everyone, I wanted to confirm the identity of one of the leaves I found in Florissant, CO back in 2017. At one point or another I saw the genus Cedrelospermum pop up on here or instagram associated with a leaf which caught my eye in its similarity to my own. I would be interested in seeing your opinions. compared to images I found elsewhere online

I found this in my backyard. Is it fossilized coral? western Colorado

This is a rock shop purchase. The owner is an expert in dinosaur gembone from the Morrison. He also deals in Hermanophyton ferns, etc so he also knows a bit about paleobotany. But this piece was a mystery to him. Its very well agatized and the fine details are preserved. At first it looks like a limb cast. The exterior is coarsely wrinkled, like bark. The cross-section does not preserve a convincing ring of a bark layer, but there is some kind of concentric character. It has some characteristics of a limb bone. The geometry and size fit that thought. But the rough exterior is a contradiction. The interior has some well developed cell structure, but its patchy. As I write this I am thinking maybe its a petrified root. Or maybe not. The first 2 photos are the same (could not delete) and are a cut and polished face. Last photo is an unpolished cut end. Its a fun one. Enjoy and I look forward to your comments.

Stabilized with Butvar B-76. Found in a basal channel facies associated with an incised valley-fill sequence of fluvial sediments; found in situ from a channel-sand-bed-load layer near the base of the valley-fill sequence. Edit: So, I copy pasted that from my power point I use to catalogue my fossils. Not sure how to remove the boxes.

Hi guys, I found this dinosaur(?) vertebrae in a Phoenix, Arizona antique shop all by itself in a dusty, dark corner. I wanted to give it life back and purchased it for a bargain price. It was only labelled "Colorado dinosaur bone". To me, it looks like Morrison Formation material based on its surprising, beautiful color. Maybe sauropod or stegosaurus??? I know it's really worn, but it has a great shape in person and very heavy for its size. Talk about size, it's 7 inches long and 4.5 inches tall even worn down this much! Any help identifying it would be awesome! Thank you!

I inherited an interesting rock/fossil from my father and wondered if it was an authentic petrified snake segment. He was a physician, and received it from one of his patients back in the 1970's. The patient was a fossil/rock hunter in the Colorado region and said it was from the area. Those are all the details I have. Are there really fossilized snake segments like this around? It appears to have a segmented outer casing of 2-3mm around the whole piece. A circular (spine?) runs through the length of the piece on one side. The interior is fully crystalized.

Does anyone recognize this type of nodule? Found at a lake beach near Granby CO -- upper tertiary/grantitic rocks (minor mafic)/ metamorphic rock boundary. Total long axis of the nodule is ~3 cm

Hello Fossil Forum members, I live in Denver. My youth hobby of rock collecting has reawakened during Covid times and I'm so happy to have this group of experts help id finds. I've enjoyed learning about fossils from the site already and am amazed and delighted with how helpful and knowledgable forum members are. I think that the concept of pareidolia is fascinating and everyone, fossil collector or otherwise, should reflect on how our brains fill in patterns. Everyone here is so encouraging too, which is lovely and much appreciated. Happy Thanksgiving.

I found this in quaternary alluviums but near a spot with a confirmed vert fossil find. It looks to me like half a cloven toe, but the mineralization seems sketchy. What do you experts think? Could it be a trace, like mud-filled footprint or is it another pseudofossil!? Thanks for humoring me!
-
I'm curious if anyone recognizes these structures. Found in Denver Basin, near fossil wood deposits. Lattice like structures, almost like giant ommatidia. Maybe a seed? Ticks in blurry scale are mm. Host rock is almost creamy, like chert/opaque agate. Thank you!

Dear Fossil forum members, I have recently acquired this bone. It is said to have been found at Mack, Colorado. I suppose it is from the Morrison Formation. The previous owner thought it might be a Stegosaurus neural arch, but now I have it in my hands I see more similarities with a supraoccipital. Especially these: (Eolambia, A and C) https://peerj.com/articles/1872/ (Fig. 12, A. Eotrachodon) https://www.nature.com/articles/s41598-019-41325-8 (Fig. 2, Q, R, S, T and their other sides, unknown hadosaurs) seem similar to me. That would indicate that my bone is probably Camptosaurus dispar, which is the closest animal to hadrosaurs to live in the Morrison Formation. However, I have not found a good comparison with Camptosaurus, nor any other Morrison Formation dinosaur. In comparison with the supraoccipitals shown above, mine is more than twice the size. Mine is about 12cm, while the other ones I found are 4 to 6 cm according to their scale bars. Is this bone a bit similar in every dinosaur or do I have a really large specimen of Camptosaurus in front of me? I hope someone can help me with this, Thank you very much in advance for your answer, Kind regards, Sander

Pretty sure this is petrified wood can you confirm this. And then the little hole on the one side is deeper than it looks in the picture (about as deep as it is wide) is there anyway to say if this was caused by erosion or from something living before fossilization
