the tatter Posted December 3, 2011 Share Posted December 3, 2011 Just a couple of the pieces I have found. Discovery consists of seeing what everybody has seen, and thinking what nobody has thought. Albert Szent-Gyorgyi Link to comment Share on other sites More sharing options...

JimB88 Posted December 3, 2011 Share Posted December 3, 2011 lets see here...the first is the lacy parts of a Lyropora (dont know where the support structure is do you?) The second is a fenestellid of some sort and the last is a polypora. Link to comment Share on other sites More sharing options...

The second is a fenestellid of some sort and the last is a polypora. Interesting.... How can you tell its the lacy parts of the bryozoan Lyropora? Lyropora sp.

JimB88 Posted December 3, 2011 Share Posted December 3, 2011 (edited) Because I find them still associated quite often here in the Bangor Limestone. Edited December 3, 2011 by JimB88 Link to comment Share on other sites More sharing options...
Indy Posted December 3, 2011 Share Posted December 3, 2011 Because I find them still associated quite often here in the Bangor Limestone. Do you have any pictures of the complete Lyropora with lace attached between the V structure?

JimB88 Posted December 4, 2011 Share Posted December 4, 2011 Heres a couple; typically they are preserved as impressions for some reason. And to answer your question: they are rarely complete (especially after I try to get them from the rock. ) Link to comment Share on other sites More sharing options...
Indy Posted December 4, 2011 Share Posted December 4, 2011 Heres a couple; typically they are preserved as impressions for some reason. And to answer your question: they are rarely complete (especially after I try to get them from the rock. ) Thanks for the pictures... The Lyropora (lacy part) typically being preserved in your area (or elsewhere) only as impressions is probably because the "lacy" part is so fragile. I knew of 1 person (many years ago) who found a 100% complete specimen in Illinois...I rarely buy fossils...But I would buy a complete Lyropora, especially if it was collected from the same IL locality (of course) I would prefer one that was NOT prepared and do my own preparation When you originally ID'd the bryozoan (picture 1 in the original post) as being associated with the Lyropora...I wondered if there are any specific features of this particular "Lace" that is "classic" Lyropora separating it from other lacy bryozoans. Lacy bryozoan fragments are everywhere in many Mississippian localities Comparing the structure in your picture with the structure in picture 1 on this thread... I do see the similarities...Thanks for sharing Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Indy Posted December 4, 2011 Share Posted December 4, 2011 (edited) While we are on the subject of Lyropora I have always wondered about a specific feature on this specimen. There is a knobby feature on the point...It is not a separate fossil attached to the end but it is part of the Lyropora. Since the Lyropora was a construction of the bryozoan builders...then there must be a purpose or reason. I'm wondering if anyone has any ideas as to what this feature represents ....other than the "Penthouse suite" for the privileged few Edited December 4, 2011 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

Could also be a reaction to a parasite as well. Link to comment Share on other sites More sharing options...

It's not an encruster but part of the bryozoan structure Reaction to a parasite/predator attack makes a lot of sense...Should have thought about that possibility considering all the attacks I've seen on crinoid. Thanks for suggesting parasite attack Barry Edited December 4, 2011 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
