3 years, 8 months ago3 years, 8 months agoI agree, this is a chain coral. Halysites is a good guess, I’m not 100% sure but it is a common genus here is the classification info: https://paleobiodb.org/classic/basicTaxonInfo?taxon_no=4897

3 years, 8 months ago3 years, 8 months agoHi @mark-ryan & @vperez – this is a weird one. I am not sure about stromatoporoid, those are calcified so I would expect better preservation. It’s possible that the circular bit on the ‘bottom’ is a nucleation point for a sponge or something trying to anchor down – so it could be an unrelated animal piece. That star shaped pattern on top is also…[Read more]

3 years, 8 months ago3 years, 8 months agoHi @patrick-hsieh & @smoran – I agree that it looks like a spatangoid. It is really hard to tell if there is still shell material? You may be able to use the Echinoid directory to get a finer identification: https://www.nhm.ac.uk/our-science/data/echinoid-directory/taxa/extension.jsp?id=584

3 years, 8 months ago3 years, 8 months agohi again @mackenzie-smith & @lisa-craig – I think this may be similar to your other find. Another Hemiaster? It’s difficult to tell from the image.

3 years, 8 months ago3 years, 8 months agoHi @lisa-craig & @mackenzie-smith – It’s definitely an irregular echinoid. It looks like Hemiaster to me, a common heart urchin. https://www.nhm.ac.uk/our-science/data/echinoid-directory/taxa/taxon.jsp?id=508 what do you think?

3 years, 8 months ago3 years, 8 months agoHi @vperez@smoran@antony-avrithis, I agree it’s likely Arcidae & would suggest looking at genera on the Neogene Atlas: https://neogeneatlas.net/families/Arcidae/

3 years, 8 months ago3 years, 8 months agoHi @antony-avrithis & @indah-huegele – This is certainly a bivalve but I don’t have much experience in recent material. I would suggest looking at the Neogene Atlas: https://neogeneatlas.net/

3 years, 9 months ago3 years, 9 months agoHi @leanne-phillips – I definitely think this a coral fossil and would encourage you to update your classification fields to Kingdom Animalia, Phylum Cnidaria, Class Anthozoa.
I agree with @leonardo-miranda that it looks like a horn coral, which would be in the Order Rugosa (or Stauriida – I think Rugosa may be a subclass now!). It is difficult…[Read more]

3 years, 9 months ago3 years, 9 months agoHi, @gillian-catlett – this is a horn coral! A solitary coral that was pretty common in the early Paleozoic.
Here is the classification information: Kingdom Animalia, Phylum Cnidaria, Class Anthozoa, Order Stauriida. I don’t know that I can identify it down to the species level but at least that’s some more info for…[Read more] -

3 years, 9 months ago3 years, 9 months agoHi, @stephanie-austin – are you looking for some help identifying this fossil?
It looks young but maybe @cameron-muskelly has some ideas as a Georgia native. -

3 years, 9 months ago3 years, 9 months agoVery nice fossil, @steve-lynn! Would you want to add in the taxonomic/classification information. I’m not a cephalopod expert but can at least help you with Kingdom Animalia, Phylum Mollusca, Class Cephalopoda, Order Ammonitida

3 years, 10 months ago3 years, 10 months agoHi, @al-halt – this is certainly a weird find. Here is some info on your location: https://macrostrat.org/map/#/z=12.1/x=-93.7087/y=36.3943/bedrock/lines/ it looks to be Devonian – Ordovician in age. I’ve been collecting in a area not too far from there and there was a lot of chert, is it possible that is what this is? Is it very hard (can’t…[Read more]

3 years, 10 months ago3 years, 10 months agoHi @daniel-park@aiden-denham@kyle-griffiths – it is certainly an echinoid test plate – or a single element from their body skeleton. Certainly a cidaroid of some kind or a regular (vs. irregular) sea urchin.

3 years, 10 months ago3 years, 10 months agoThanks @sadie-mills. I agree with @paul-mclain it looks to be a section through a bryozoan. It could be a small coral fragment too, hard to tell since it’s fragmentary and worn!

3 years, 10 months ago3 years, 10 months agoThanks for tagging me in @sadie-mills. @chad-bruce – this looks like several different species of brachiopod shells that have been worn down. The Fossil Guy has a good page on Devonian brachs of NY (similar species to MI): https://www.fossilguy.com/sites/18mile/18_col.htm you should see some similar shapes!
