RCFossils Posted May 26, 2009 Share Posted May 26, 2009 Last week I visited an old collecting site just outside of Chicago with a friend of mine. It was originally the remnant of a dug out canal back in the late 1800s that hit bedrock and exposed a portion of the Niagaran Limestone. At one time this had been a very good collecting site for Silurian aged fossils. I beleive that several dozen species of trilobites and over 70 types of crinoids have been found in this area. It has been long neglected and the site was very overgrown but me and a friend of mine did manage to locate a productive site and collected quite a few trilobites, several crinoids and a few interesting nautoloids. I still have quite a bit of prep work but will attach a few pictures of some of the days finds. It definately pays off to check out some of the old collecting sites.

RCFossils Posted May 26, 2009 Author Share Posted May 26, 2009 Excellent fossil finds. I like those trilobites. Is the matrix dolomite? Hi Ron, Yes it is a dolomitic limestone. I think it is the same cap rock as the Niagara Falls hence the name. Link to comment Share on other sites More sharing options...

Guest solius symbiosus Posted May 26, 2009 Share Posted May 26, 2009 Nice! Calymene celebra??? We have that same rock around here, though, it pinches out to the South due to an erosional unconformity. Link to comment Share on other sites More sharing options...
trilospain Posted May 26, 2009 Share Posted May 26, 2009 I have a Sthenarocalymene celebra from many years ago, it was labelled as: S.celebra Springfield FMC Wayne County, Indiana I suppose that information is correct, isn't it? Link to comment Share on other sites More sharing options...

I would assume. Calymene sp is a genus that has been assigned to numerous different classifications throughout the years. I think that Sthenarocalymene is the most recent, but one still sees the use Calymene in publications... I would check the Treatise to be sure.

Yes, it's true, Sthenarocalymene is the most recent. According to this paper "RECLASSIFICATION OF A COMMON CALYMENID TRILOBITE FROM SILURIAN CARBONATE DEPOSITS OF SOUTHWESTERN OHIO" (i only have the abstract), it has been referred as Calymene celebra, Flexicalyemene celebra, Gravicalymene celebra, and Sthenarocalymene celebra.

RCFossils Posted May 27, 2009 Author Share Posted May 27, 2009 Thanks for thew comments! It really does pay to investigate old collecting sites. Most of them will be disappointing but occasionally you might get lucky. I also have a partial arctinurus that was collected from this local.
