Callianopsis Shrimp Claw Fossil

Here is a fossil I profiled in August 2012. My cousin brought this back from Washington state and yesterday he prepped it. This picture shows a picture of it August and now January 2013.
We think this is a claw from a ghost or mud shrimp called Callianopsis. The fossil could be from the Lincoln Creek formation of the Oligocene epoch.

Thanks Kenny for the pictures!

Cheirurus Trilobite Cephalon

I believe this trilobite cephalon fragment is from a Cheirurus sp. It was found in the Waldron Shale of Clark County, Indiana and is from the Silurian Period. In March 2010, I documented another fragment that is less complete. See that posting here. This new fossil seems to have one of the compound eyes. Unlike the other which was a cast, this one has fossilized shell.
The fossil shown is over 2 cm in size and has not been cleaned yet. The other eye may still be embedded in the matrix.

Heliophyllum Horn Coral with Aulopora

This fossil has been prepared with abrasive cleaning to reveal a nice Aulopora coral colony growing on a larger Heliophyllum horn coral. The fossil is from the Devonian Period and was found in Clark County, Indiana, USA. Thanks to Kenny for loaning it to me.
