4 years, 7 months ago4 years, 7 months agoHi, @heath-carroll I’m not seeing a coprolite but possibly there are fragments of fossils in the rock, it’s hard to tell from the image.

4 years, 7 months ago4 years, 7 months agoHi, @heath-carroll That’s a big rock. What sort of fossils are you seeing in it? Is it very hard, such that your finger nail cannot scratch the rock? Talk to you soon, Jen

4 years, 7 months ago4 years, 7 months agoHi, @heath-carroll is this a different view of the specimen you think is related to Batoidea? Could you take a more in focus photo of that large gray bit?

4 years, 7 months ago4 years, 7 months agoHi, @heath-carroll – are you seeing a ray in here? I’m not sure I see anything specific in the rock.

4 years, 7 months ago4 years, 7 months agoHi, @heath-carroll – any ideas on what this might be? The pattern is really interesting. Did you find anything else near this specimen? Talk to you soon, Jen

4 years, 8 months ago4 years, 8 months ago@heath-carroll and @jbauer it appears that the majority of Carroll Co., Iowa is Cretaceous and the remainder is Pennsylvanian so wood is definitely possible in terms of age. To me it seems like there is the impression of wood on the lower part and there could be a complete stem on the upper part of the rock but a little hard to tell. We can only…[Read more]

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll – I’ll tag in our plant expert – @mackenzie-smith. I can’t tell if it’s plant material or mineral growth. Is this still out where you found it or did you bring it home with you?

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll – The classification would be as follows: Kingdom Animalia, Phylum Echinodermata, Class Crinoidea. Then you could put crinoid in the common name since that’s how we refer to them in general conversation. Does that all make sense?
Here is a link to a database that helps with classification:…[Read more] -

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll – did you take this specimen home with you or is it still out where you found it? It looks kind of like a smushed brachiopod but I’m having some difficulty telling.

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll – did you clean this one up yet? It’s hard to tell what it is from the image. Does it look like a fossil shell?

4 years, 8 months ago4 years, 8 months ago@heath-carroll – The brachiopods certainly look Devonian but compare the rock of your unusual specimen to the other rock, it just doesn’t look the same. There are chunks of other rock and the underlying matrix is really white. I think you may just have a really strange rock.

4 years, 8 months ago4 years, 8 months ago@heath-carroll I’m still not seeing it. My initial thought was that it could be an echinoderm but they aren’t often found in conglomerate rocks because they break apart really quickly. Most echinoderms from Iowa (the eastern half) will be more gray and muted. They also have a series of plates that make up their skeleton that should be visible…[Read more]

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll this definitely looks like a fossil echinoderm. Probably part of a crinoid stem. If you edit your specimens you can add in information on classification, location, and more. Otherwise, I can just include them in the groups for conversation rather than as specimens with data. It has to do if you click that check box in the app…[Read more]

4 years, 8 months ago4 years, 8 months ago@heath-carroll this is definitely more in focus, can you tell us a more detailed location of where you found this? Is it from Lake View or is that where you took the image?
Here is a link to a digital bedrock map: https://macrostrat.org/map/#/z=11.5/x=-95.0010/y=42.3093/bedrock/lines/I’m still not convinced it is fossiliferous.

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll, same issue, I’m having trouble picking out features because the specimen is out of focus. My instinct says rock.

4 years, 8 months ago4 years, 8 months agoHi, @heath-carroll This is a bit too out of focus to zoom in on – is that flat disk what you think is a fossil? It has an echinoid shape but I can’t zoom in on the features.
