PetrolPete Posted June 2, 2012 Share Posted June 2, 2012 I found a number of concretions from the oolagah lime formation (Pennsylvanian age) and I've been popping them over the last month. I've managed to ID some of them (I think) but there are several othere I need help with. Pyritized orbiculoidea (I think) A soft bodied organism of some sort? (for scale it is slightly larger than a quarter, my scale pic was too large to load) Another orbiculoidea? or another bivalve of somesort? more pics to come Link to comment Share on other sites More sharing options...
PetrolPete Posted June 2, 2012 Author Share Posted June 2, 2012 Here are some more No idea what this might be, there is another piece to it that I'm still trying to split also have no idea what this one might be, if anything (a little larger than a quarter, scale/complete concretion pic was too large) possibly a bivalve or soft-bodied organism? more to come Link to comment Share on other sites More sharing options...
PetrolPete Posted June 2, 2012 Author Share Posted June 2, 2012 another soft bodied creature or bivalve? no idea, a pyritized something soft-bodied creature of some sort? another Orbiculoidea? Link to comment Share on other sites More sharing options...
Auspex Posted June 2, 2012 Share Posted June 2, 2012 My old eyes are having a tough time seeing any details, because the photos are so dark.

JimB88 Posted June 2, 2012 Share Posted June 2, 2012 The orbi is neat! Keep in mind that concretions can form around even tiny fragments. I think the 'soft bodied animals' in this case are just the first part of the concretion to form. Also keep in mind that soft bodied preservation is extremely rare! This is what makes the Mazon / Braidwood / Essex site so special! Icollect ironstone nodules here in TN, but all I find are orbi's and other brachs.

Rockin' Ric Posted June 2, 2012 Share Posted June 2, 2012 I think you are right when you say the top picture is a orbiculodea. Here is are some found in Alabama. WELCOME TO ALL THE NEW MEMBERS!

Wrangellian Posted December 26, 2012 Share Posted December 26, 2012 Just found this thread... trying to tease out some of the detail from your photos (maybe could be more successful if you did overexpose your photos at least a bit): I'd say at least one of them could be Orbiculoidea Link to comment Share on other sites More sharing options...

FossilDAWG Posted December 30, 2012 Share Posted December 30, 2012 Try taking the photos with a darker background. The light background is likely fooling the light sensor into setting an incorrect exposure. Also, often it is possible to angle the light to bring out surface detail; direct light straight onto the subject makes everything look flat and washed out.
