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!

  

  

 

Ordovician Period Tube Coral?

An exploration of the microscopic fossil world of the Ordovician Period uncovered this cluster of tube like fossils. Is it some sort of coral? Maybe a cluster of worm tubes?

I am not sure.

It was found in Grant Lake Formation of Bullitt County, Kentucky. The microscope was set to 40x magnification.
