Here is a picture of worm burrows. It was found in Mississippian Period rock in Floyd County, Indiana, USA.

Thanks to Kenny for the picture.

Platyceras dumosum pileum Snail Fossil

Picture of what appears to be a Platyceras dumosum pileum gastropod fossil. It was found in the Devonian limestone of Jefferson County, Kentucky, USA. This fossil is some sort of spiny snail.

Thanks to my cousins Kenny and Chris for the pictures of this fossil!

Ambonychia Pelecypod Fossil with Bryozoan

This fossil appears to be an Ambonychia clam fossil with both valves. It is has quite a bit of matrix covering detailed parts. The clam fossil has a colony of cyclostome bryozoan (see this web site image or called ctenostome type on this web site).

The fossil still needs to be cleaned to see if more shell and bryozoan detail can be revealed. It is rare for me to find clams with both valves intact so this was a happy discovery.

The fossil was found in the Kope Formation of Carroll County, Kentucky, USA. These creatures existed in the Ordovician Period.
