Microfossil Crinoid Spines?

These microfossils were found in the Lexington Limestone in Franklin County, Kentucky. They appear to be some sort of spines maybe belonging to a crinoid.  Magnification was set to 40x.  Fossils are from the Ordovician Period.

 

  

 

Lexington Limestone Scolecodonts

 

My cousin loaned me a Orion MicroXplore MFL-06 since my digital microscope broke.  It has a 4x objective lens with a 10x eyepiece lens.  I used a Kodak LS743 compact camera in macro mode to take images though the eyepiece.  Using Photoshop CS4 processed the images to show on the blog.  I took one shot of a mm scale on a ruler to get a rough idea of scale.  I then used the Photoshop Analysis tool to set a pixel value for 1 mm for the Ruler Tool.  This tool was then used to measure points on some scolecodont fossils.

  

 These fossil remains of an Ordovician Period polychaete annelid worm.  Fossils found in the Lexington Limestone of Franklin County, Kentucky.  Thanks to Herb for the material to study.

  Below is an image to give the reader a perspective as to the size of these fossils and why a microscope is needed to study them.  All the fossils for this post are on that business card.

 

  

  

  

  

  

These last two images I am not sure about.  They might be scolecodont fragments.

  

 

Kope Formation Cyclonema Fossil

These partial fossil molds of the ancient gastropod Cyclonema were found in Carroll County, Kentucky.  This snail existed in the Ordovician Period.  The fossil was found in the Kope Formation.  It is of the class Gastropoda, suborder Euomphalina, and superfamily Platyceratacea.  The genus Cyclonema was named by James Hall in 1852.  Usually the fossils I find in the Kope Formation are quite small but this fossil is almost 3.5 cm long.  This fossil has part of fossilized shell.
