Ordovician (St. Leon, IN)

[Peat Burns]

This is a trip to St. Leon, Indiana (Late Ordovician), that I took on Tuesday the 28th.  Weather was cloudy, 66 deg. F.  Conditions were wet and muddy, but a lot of fresh material had weathered out and was exposed from the winter.  More or less typical finds.  The complete Ambonychia steinkern was the trip-maker for me.  

 

Here is a view of the roadcut.

Thanks, doushantuo.  This is Cincinnatian (North American) Epoch; Liberty and Waynesville Formations, mostly.

More reasons to keep St. Leon on my bucket list. Especially love the Ambonychia and the Hiscobeccus. REALLY COOL! Congratulations on a successful day. Thanks for sharing your excellent photos.

Great finds! Love the picture of the Hiscobeccus. Also envious of the enrolled flexi. I have been there twice and have come away empty handed in regards to this trilobite. Great place to hunt for the general public.

Hey, Jeffrey P and minnbuckeye....you seem to like the hiscobeccus brachiopods pictured. Their herringbone detail gives them a lot of character.

Those things are very plentiful around this area...I literally have hundreds. Prepped and unprepped.

 

I'm willing to share. Trade??  That goes for anyone interested, actually. Send me a PM
