Kope Formation Scolecodont

Okay, I have been a little off on the scoledont identifications recently but this one I am pretty sure of. It is the only jet black fossil I found have viewing tablespoon after tablespoon of gravel.  It is from the Kope Formation of Carroll County, Kentucky.  This creature existed in the Ordovician Period.

Looking through all the Kope Formation material I did find over 15 Cornulites tubes.  I will post images of the smaller ones soon. 

The jaw appears to be broken off at both ends. Image taken with microscope set to 40x.

 

 

Gastropod Microfossils

Ordovician Period gastropods found in Grant Lake Formation of Bullitt County Kentucky. Used microscope at 40x to view and photograph these fossils.

Scolecodonts and Trickery

UPDATE: My original post listed the fossils in the following pictures as conodonts.  After some feedback from Shamalama and Herb, they informed me that some are trilobite cephalon fragments and others are scolecodonts.   I have edited this post to reflect the correct information.  Okay, I had to correct this post a second time since I assumed the trilobite was a Cryptolithus when it appears to be a Acidaspis.

These first three fossils are scolecodonts. Fossils found in the Kope Formation of Carroll County, Kentucky usually consist of just their jaw remains. These fossils date to the Ordovician Period.

 

  

  

These last three images are of cephalon (front part) of a trilobite (maybe Acidaspis?).  The Kope Formation location I was at has quite a lot of larger fragments.  See the comb like structure fooled me into thinking they were broken off teeth.  I need to be more careful next time!
