Multi-Stem Crinoid

At the last KYANA fossil study, I found this multi-stem Mississippian period crinoid. That is one condensed group of crinoid arms in one place!

This one was found in the Lake Cumberland, Kentucky area.

A Silurian Dawsonoceras annulatum

Here is a Silurian period cephalopod classified as Dawsonoceras annulatum. 


It looks like a small part of its shell is left (the pinkish looking rock with the sine wave shapes in it). The rest of the fossil is just an imprint on a rock.

I found this specimen at KYANA fossil study and always like find this cephalopod fossil. More to come.

Dalmanites limuluris Trilobite

Here is a picture of a Dalmanites limulurus trilobite from the Silurian period. It was embedded in Rochester shale.

The image was taken at a dealer tent at the Falls of the Ohio State Park located in Clarksville, Indiana during the Fossil Festival.
