Found123 Posted May 9, 2021 Share Posted May 9, 2021 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.

val horn Posted May 9, 2021 Share Posted May 9, 2021 I have a few ideas, and less knowledge. The biggest piece in the last photo looks like it might be a coprolite, the second picture from the top appears to be a tooth. Can you provide more geological information and individual sharp pictures to give people a easier place to start. 1 Link to comment Share on other sites More sharing options...
Found123 Posted May 9, 2021 Author Share Posted May 9, 2021 Thanks so much- these were found in layers of limestone and chert around Pueblo Colorado. I wish I knew more about the geology, I’m sorry. Next time I will take a photo of where we are digging- you can see the layers better. ive tried to shoot some better pictures. I believe the jagged pieces are bone. thanks again!

Top Trilo Posted May 9, 2021 Share Posted May 9, 2021 I think most of these are geologic. the only one I would be for sure of is the tooth but have no idea what animal it may have come from. Since you know where they are from you can use a geologic map and find the exact location and then just let us know the age of the rocks. https://ngmdb.usgs.gov/mapview/?center=-97,39.6&zoom=4 2 “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

(I forgot the name for the straight kind). Plus a few of the rounded ones look like sequoia cones. The needles ones are NOT fossils. Last pic is NOT fossil but just mineral veins. I see a shell piece - kind of like scallop but not sure about the other one - could be broken up big oyster. Link to comment Share on other sites More sharing options...

The specimen here appears to narrow quickly and there is a line in the middle of the second picture along with an interesting color and shininess. While belemnites could have some of these traits I would lean towards tooth although there's a good chance I'm wrong “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

I'm not experienced with the area anyway and just giving a second opinion. That one broken sphere piece look definitely like a cone to me. Most of the other spheres look more like typical mineral formations. Link to comment Share on other sites More sharing options...
Daniel Fischer Posted May 10, 2021 Share Posted May 10, 2021 Some of the ones in the last picture look like some kind of bedrock so no fossils if that's the case. Link to comment Share on other sites More sharing options...
val horn Posted May 10, 2021 Share Posted May 10, 2021 the one with the fan is a trace fossil a have heard it called a roster tail, and it is a feeding trace; I have seen it in devonian formations but am not sure if it is restricted to devonian age. 1 Link to comment Share on other sites More sharing options...

I think it is a piece of an Inoceramid... a large Cretaceous clam common in and around your part of Colorado. They can be IDed by this crystallypattern, and around the hinge you get the pattern in a fan-shape like this one. The only other one I think is a fossil is the tooth. Looks lie a broken shark tooth.

LabRatKing Posted May 10, 2021 Share Posted May 10, 2021 I agree with the others, I see innoceramid fragments, but mostly I see limonite, selenite, and various pyrites similar to what I find across the southern plains and front range. The good news is you have the right idea, and live in a great place for multiple fossil day trips! Link to comment Share on other sites More sharing options...
