Silurian Cephalopod

Here is another Dawsonoceras annulatum imprint in a rock that is part of stone wall. I wish I had a ruler to measure it but I think it might have been about 24 cm long. It appears to have 19 sections.

Found at KYANA fossil study.

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.
