The fossil man Posted August 4, 2017 Share Posted August 4, 2017 During a trip in the Ozarks mountains, I found some fossils. There were lots of crinoid fossils, as well as some brachiopods. However, a few fossils seemed odd to me. Does anyone know what these are? Are they fossils or just crystal formations? Link to comment Share on other sites More sharing options...

Ludwigia Posted August 4, 2017 Share Posted August 4, 2017 The last and the 3rd and 4th to last photos show coral. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 4, 2017 Share Posted August 4, 2017 They all look like coral to me... “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 4, 2017 Share Posted August 4, 2017 Picture 2 looks like a Bryozoan - the others all look like Rugose Corals, to me. (Also known as "Horn" Corals. Neat finds.

I'm just wondering because it kind of looks like a fossil coral (which I thought was a bryozoan, but people here on TFF determined was a coral) that I received as a gift a few months ago: Monica Link to comment Share on other sites More sharing options...

My coral knowledge is sadly lacking. Maybe @TqB will have a look.

Rockwood Posted August 5, 2017 Share Posted August 5, 2017 Something to accurately show the scale is critical for that determination. Link to comment Share on other sites More sharing options...

As @Rockwood says we need to know the diameter of the pores (represented by the infills here, the walls having dissolved). Over 1mm or so and it should be something like Thamnopora. All the similarly shaped trepostome bryozoans I've looked at are below 0.5mm though I've never been able to find a definitive statement on the size ranges.

doushantuo Posted August 5, 2017 Share Posted August 5, 2017 Lecompte's depiction of a Thamnopora species("Favosites cervicornis" de Blainville) TqB,I take it you are referring to the May*(1997) piece ? *The scientist,NOT the month Link to comment Share on other sites More sharing options...
TqB Posted August 5, 2017 Share Posted August 5, 2017 "TqB,I take it you are referring to the May*(1997) piece ?" @doushantuo Actually no, I don't know that one. Tarquin Link to comment Share on other sites More sharing options...

And a quick glance shows Thamnopora corallite peripheral diameters have a wide range of about 0.4 - 3mm. So the lower end just overlaps with large bryozoan openings.
