thanatocoenosis Posted July 16, 2012 Share Posted July 16, 2012 "Fenestrate" has become a term used very loosely for anything lace-like but there are many lace-like bryozoans of many orders and families and only a few are known as Fenestrella. If you want to get an idea of the huge bryozoan diversity in the Ordovician visit Steve Holland's websites, both the one on Cincinnatian Arch and the Nashville Dome: http://strata.uga.edu/ go to the "fossils" section of each site. Great site! Dr. Holland(and his grad students) did some of the pioneering work on sequence stratigraphy working the Upper Ordovician rocks of Kentucky and Ohio. It is my understanding, and how I colloquially use the term, that "fenestrate" and "lacy" refer specifically to the Fenestrida order of Bryozoa. Probably, a more appropriate term would be fenestrid bryozoans. 2012 NCAA Collegiate Round Ball Champs; and in '98, '96, '78, 58, '51, '49, and '48, too.

Probably, a more appropriate term would be fenestrid bryozoans. You say po-ta-toe, I say poe-tat-o... I was just thinking how various amateur collectors I know use the term. Not at all from a true taxonomic point. For as much as I love bryozoans and often attempt to sort them out, I still get dizzy in doing so. Link to comment Share on other sites More sharing options...
thanatocoenosis Posted July 16, 2012 Share Posted July 16, 2012 I recently spent 2 weeks uploading scans of sections and acetates, with descriptions, into a data base. I never want to see another one as long as I live. 2012 NCAA Collegiate Round Ball Champs; and in '98, '96, '78, 58, '51, '49, and '48, too.

Ameenah Posted July 16, 2012 Author Share Posted July 16, 2012 (edited) There isn't much I can do with the camera I have. I even used 2 magnifying glasses lol Edited July 16, 2012 by Ameenah Explore -> Dream -> Discover ! Link to comment Share on other sites More sharing options...
erose Posted July 16, 2012 Share Posted July 16, 2012 (edited) There isn't much I can do with the camera I have. I even used 2 magnifying glasses lol I think you just need to keep your eyes open for similar specimens that might be just a bit better. Also this is a good reason to get a 10X magnifier and even a 20X if you really want to take a closer look. Not for the camera, but for your own eyes.

I agree, a 10x loop should be one of the first acquisitions of any geology student or amateur paleontologist. These days, even triplets can be picked up, cheap, on-line... probably, more important than a hammer, even. 2012 NCAA Collegiate Round Ball Champs; and in '98, '96, '78, 58, '51, '49, and '48, too.

Herb Posted July 16, 2012 Share Posted July 16, 2012 I think this will get you there: LINK Thanks, I've used this site before, could use a few more pictures though.My guess for a bryozoan was Chasmatopora but my references say it's Silurian, but the UGA site says it is in the Ordovician also. It might not be the camera, the specimen might be too weathered for more detail.

Missourian Posted July 17, 2012 Share Posted July 17, 2012 I'm curious as to why some members think this is a fenestrate??? Without a section, it is next to impossible to determine, but fenestrate??? Trepostomate or tubuliporate, perhaps, but fenestrate? Perhaps, it is my ignorance, but I associate fenestrates with that box-like fan shaped structure. Someone, enlighten me. My bad. I should have said it is "an organism". Context is critical. Link to comment Share on other sites More sharing options...

Note the bore holes caused by another animal. Cyclostome usually grows on a brachiopod, and it is about very thin, like a pencil mark' It think her specimen is growing on the rock and the Prasopora is frond-like.
