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.

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?
-
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 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.

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 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).

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.

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

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

Hello, I have a large canine tooth (~14 cm with the root, ~6.5 cm with just the tooth) from the White River Formation that I collected this summer on privately held land in northeastern Colorado, and though the fossil in its natural state is fantastic as-is I’m thinking about doing a little bit of restoration on the fossil and am looking for some insights. The tooth itself is from either an entelodont or the rhino Metamynodon, with the shape of the tooth and root strongly suggesting the latter to me (feel free to speak out if you have an opinion one way or the other, though I’m not specifically asking for an ID in this thread). I found the tooth in several pieces and glued everything that I could find back together. I have most of the tooth, but only a small piece of the tip remains. Also, I have not glued the tooth back to its root, and instead simply display them together as if they were connected. I am thinking about restoring the rest of the tip by sculpting it in using paleosculp from Paleobond, using what piece of the tip there is as a guide. I am looking for any information anyone can give me on paleosculp and the process of restoring a fossil using this material. Would this be the correct product for the job? Is there anything I should know when working with the material? Is restoring the tip of this tooth even a good idea at all, or in the name of science should I leave it as I found it? I intend to leave the paleosculp unpainted for the purposes of not risking damage to the fossil and also making it obvious which pieces of the fossil are original (most of it) and which pieces are restoration (just a little section of the tip). I understand that dinosaur teeth are frequently restored in this way, but I want to make sure that I’m not committing blasphemy by doing such a restoration. Also, paleosculp is advertised as being sand-able and drill-able after it dries, and so I figure if the restoration ever needs to be removed for whatever reason it could be sanded away in a labor-intensive process, but do let me know if this is not the case. I also intend to clean the fossil up a bit more (ie get rid of some of the residual dirt still on it) and potentially glue the tooth onto the root. Thank you for any insights and information you may have! Picture of the fossil and of the tooth tip provided for context.

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!
-
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!
-
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

Since I live so close to the famous Morrison Formation I thought I would start doing some research on what it's like to fossil collect in it because I'm seriously considering finding a way to gain access to some private land and do a little bit of collecting. I have heard it said once that the rock of the Morrison is hard and requires special tools to dig in, and that consequently it's impossible to prospect for fossils in the Morrison the same way you would in, say, the Hell Creek Formation. How true is this? Is the only way to fossil collect in the Morrison to be in a quarry? My plan for gaining access to land to collect on is to simply ask landowners if I may fossil collect their in the same way that a hunter might ask a land owner if they can hunt on someone's land. I understand that the more committed of us fossil collectors will do this to gain access to collecting sites, but is there any reason why I should avoid this approach regarding collecting on the Morrison? Thanks for any information anyone has.

I found these pieces today, the one on the left is wood but unsure if it is petrified or not, it sinks but that might be because rocks are attached on the other side, I could light it but I’d prefer a safer method. The one on the right is most likely a rock but I find the shape strange like maybe a piece of petrified branch? Thanks for the help

Hey all, I'm brand brand new to the fossil world. As in, went out to try to find fossils (on a legal collecting site) yesterday for the first time after a bit of reading. I'm in Colorado, and I was looking in an area that is known to have a lot of fossils and there is a lot of erosion exposing different layers. But I really don't know what I'm looking for. I presume all of what I found (or at best, most) is just different coloured rocks (the black spots maybe oxidation from iron content?) but how can I tell fossil from rock? So I thought I'd post some of what caught my attention here and see if anyone can point out to me why these are just rocks and not fossils, if in fact that's the case, so that next time I know to pass them up. (The only one I'm seriously questioning is the small grey one in my hand -- it sort of looks like a fern impression to me? Anyone else see it?).

Over the course of 4 trips to an alluvial outcrop in the Denver CO area I found these fossil-like pieces that ended up fitting together. No idea what it is. Would love expertise opinion. I found a fossilized cochlea near here so think it's a fossiliferous area. Also lots of fossil wood in the patch. Tertiary?
