Ordovician Cephalopod

Here is a 14 segment Ordovician cephalopod found on a Taylorsville Lake Road cut in July during a geological society field trip.

Platyceras dumosum

Here is a gastropod or snail from the fossil collection of Louisville's Charlie Oldham. I believe it is a Platyceras dumosum (Conrad, 1840) from the Devonian Period. I thought these creatures were somewhat rare but recently I keep seeing fossils of them. It is usually found in the Jeffersonville Limestone.

Trilobite Website

Today, I do not have a picture but a website link. It is called From the Collection of Bob Schacht and he has some pictures of some fully intact trilobites from Indiana. The pictures show a very impressive collection of trilobites!

The only one I have that he shows is the Phacops rana from Clark County, Indiana. If you go to the Devonian section of Speeds Quarry in Clark County you will find rolled up pieces and maybe intact specimens of this trilobite. I also found some when living in a subdivision in eastern Jeffersonville located in Clark County in Indiana.
