3 years, 10 months ago3 years, 10 months agoI agree with both of you!! @samantha-ocon & @matthew-gramling
There may be some literature on this formation you are working in, have you tried looking for any on google scholar? That’s usually my go to. If you find something you don’t have access to let Sam or I know and we can get it through our institutions. -

3 years, 10 months ago3 years, 10 months agoHi @matthew-gramling –
I agree with @samantha-ocon it’s a strophomenid. It looks like a sowerbyellid to me.Orthids tend to have more complex ornament than the simple straight lines. But it’s certainly hard to tell with only one valve that’s…[Read more]

3 years, 10 months ago3 years, 10 months ago@matthew-gramling – good question… I don’t think it’s a strophomenid, the faint thick ridges suggest that to me… I’m not sure I could assign it to one of the orders in Rhynchonellata because I’m just not familiar enough with them at the moment. I wonder if @nathan-newell has any insight? I’m leaning towards Orthida but it’s mostly a guess…[Read more]

3 years, 11 months ago3 years, 11 months agoThis is a tricky one, @kristen-cotiaux. There is certainly a pattern, my immediate thought was it could be an octocoral, it could be a different type of scleractinian coral -they come in many shapes and sizes but it also could just be a cool weathering feature like @samantha-ocon said. =/

3 years, 11 months ago3 years, 11 months agoYup, I agree with @samantha-ocon!
Kingdom Animalia > Phylum Cnidaria > Class Anthozoa > Order Scleractinia -

3 years, 11 months ago3 years, 11 months agoI agree with all above. It’s probably a crinoid stem but hard to narrow down any more info without a location and better images!

3 years, 11 months ago3 years, 11 months agoHi, @santino-diaz & @daniel-park – I agree with @colefossilfinder-blitz too! I think it’s just a rock, it is a really interesting shape! It’s certainly not fossilized bone material, it would have a much different texture and appearance.

3 years, 11 months ago3 years, 11 months agoHi @tauno-stark – it looks like this may be a very weathered coral. It’s hard to tell what kind, based on the shape of the corallites (circles, where the coral polyp lives) I would guess a rugose coral – these are the same animals that form the Petoskey stones.

3 years, 11 months ago3 years, 11 months agoHi @tony-gascoigne-bates – it looks like the cross section of a shelly.
I’m not familiar with the geology of Greece, so am not sure I can narrow it down from there. It could be a brachiopod or a bivalve depending on age and environment. -

3 years, 11 months ago3 years, 11 months agoAbsolutely, @sadie-mills! @tauno-stark this looks like a very weathered tabulate coral!
https://www.digitalatlasofancientlife.org/learn/cnidaria/anthozoa/tabulata/You could update your classification to be Kingdom Animalia, Phylum Cnidaria, Class Anthozoa, Order Favositida.

3 years, 11 months ago3 years, 11 months agoHi @nestor-blanco – Thank you for the additional photos!
I think it’s a concretion. Let me tag in @mackenzie-smith who has experience in other time periods than I do. -

3 years, 11 months ago3 years, 11 months agoHi @nestor-blanco – what does the other side of this specimen look like? It’s difficult to tell if it’s a fossil from this view. Concretions also form like this and several other things that look biological but aren’t! That being said – it could also be biological! I am not sure that it is a stromatolite, @daniel-park.

3 years, 11 months ago3 years, 11 months agoVery cool fossil! If you are interested you could update the taxonomy to be Kingdom Animalia, Phylum Cnidaria, Class Anthozoa

3 years, 11 months ago3 years, 11 months agoHi @angela-baxter & @i-edwards – it’s certainly possible it’s banded chert! It’s hard to make a confident ID without more images. Chert would be pretty hard so if you tried to scratch it with the penny it shouldn’t make a mark. If it was calcite it may make a mark! Could be a next step test.

3 years, 11 months ago3 years, 11 months agoInteresting specimen @angela-baxter. This certainly looks like a fossil. Are there any other features on the other side? And to confirm you found it in Michigan?
It’s possible it is a stromatoporoid, sort of a mat forming sponge that forms in interesting layers with bumps on the top. https://en.wikipedia.org/wiki/Stromatoporoidea

3 years, 11 months ago3 years, 11 months agoHi, @gail-boris – @sadie-mills is right, it’s an echinoid! You can update your classification to be Kingdom Animalia, Phylum Echinodermata, Class Echinodea. It looks to be an irregular form, you can use the echinoid database to look through images and find a similar fossil:…[Read more]

3 years, 11 months ago3 years, 11 months agooof @samantha-ocon you must think I am a wizard! it is so hard to identify brachs like this! It looks sort of like an orthid to me but since it’s a partial mold the best I can say is Class Rhynchonellata!
