    @vperez – this is a specimen in the UMMP database, not myFOSSIL – should have specified, sorry. @cindy-lockner – I think you got it! Someone must have dropped the bi- prefix. Thanks for your insight!! Sometimes the typos are just enough that googling simply doesn’t provide any results!

    Hi everyone, I am cleaning up our database and ran into a name I couldn’t find but the specimen is recorded as being from the Miocene of the Calvert Cliffs  so I wonder if @vperez or @bill-heim may recognize a typo that is causing my google searches to fail… It is likely (but not necessarily) an invertebrate: Cordula idonea

    • Hey Jen! Can you send a link to the specimen in question? I don’t recognize the name either, but may be able to recognize the specimen if I saw it. When I search myFOSSIL for Cordula no results come up.

    • Hi Jennifer- could it be Bicorbula idonea?

    • @vperez – this is a specimen in the UMMP database, not myFOSSIL – should have specified, sorry. @cindy-lockner – I think you got it! Someone must have dropped the bi- prefix. Thanks for your insight!! Sometimes the typos are just enough that googling simply doesn’t provide any results!

    • Thanks for catching that. I was starting to go through my invertebrate references. Fortunately, I took the time to mask up and decontaminate with plenty of sanitizer afterwards.

    Ah, @patrick-hsieh. Cyrtina makes more sense! Yeah, there are some minor things on your specimen that don’t seem to match any of the genera super well. Sometimes there are just weird forms! I think the diagnostic utility of costae can vary between different brachiopod groups X.x

    I agree with the sea urchin identification & double down with @patrick-hsieh‘s suggestion to use and explore the echinoid directory – it’s such a great resource with amazing images. You could update your taxonomy to be Phylum Echinodermata, Class Echinoidea

    Hi all – interesting finds, @a-trilobite. I think I agree with @nathan-newell on this one – it’s hard to pick out anything that’s definitely biological in these specimens.

    Thanks for the tag, @matthew-gramling.
    I agree with @patrick-hsieh that it is some form of chain coral, Halysites is a good guess – it’s a common genus.

    Thanks @daniel-park! These are relatively old museum dioramas that were made into 3D so we didn’t have much say on the animals! Cenozoic dioramas coming eventually!

    Hi @patrick-hsieh & @smoran – I don’t think it is Cyrtospirifer, there isn’t a clear fold and sulcus like I would expect with that genus. It looks more similar to Platyrachella but again no fold and one valve appears to be pretty flat maybe a little concave? I am not sure it is a spiriferid, why were you thinking that? Maybe some context would help.

    @mark-ryan – this is very interesting. It’s so fun to speculate!!! Especially when everything is so unknown. It’s certainly a possibility that the single star shaped feature is an astrorhizae – but I’ve never only seen one have you? Usually it’s a whole mess across a surface, usually associated with monticules – but these are usuals, there are…[Read more]

    Hi @vperez and @danita-brandt – I can’t say much past what Danita has already guessed. It’s possibly a columnal or a holdfast… certainly echinoderm material but not being super familiar with the location or formation I’m not much use.

    Hi @vperez and @jacob-beasecker – I agree more with Jacob’s identification of Cayugaea. It is difficult to tell with a weathered corallite. Jacob do you have a copy of the Strata and Megafossils of the Middle Devonian Silica Formation? It was recently (last 6 ish years) reprinted with really nice images. Talk soon, Jen

    @smoran this is another Atrypida specimen if @jacob-beasecker wants to narrow down the taxonomy to the order, but again – hard to get to a species ID with only one view.

    Hi @smoran I would agree that this seems to be a Pseudoatrypa but it is difficult to confirm species ID from one image. If @jacob-beasecker would like to post additional images I could take another look. Are you from Michigan, Jacob? Glad to see more local fossils on the site!

    Hi all @samantha-ocon@matthew-gramling@sarah-gripe@leonardo-miranda interesting find. I would guess it would be a smushed conulariid (jelly fish relative) or a straight cephalopod. Location indicates probably Mississippian in age.
    It looks like a mold which makes it hard to tell but conulariids have perpendicular ornamentation – which you seem…[Read more]

    I 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

    Hi @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]

    @smoran@samantha-ocon – I’m afraid I can’t go below productid, most of the specimen is missing which makes it hard to ID.
