Dalmanites Trilobite Shell

School has been keeping me very busy in recent weeks but I did get a chance to hunt for Silurian fossils the other day. Somewhere there is a Dalmanites trilobite layer in the Louisville limestone layer in Louisville, Kentucky. The rock I found was part of that layer.

I was lucky enough to find this shell fragment instead of an imprint.

The same rock contained some more shell fragments and a larger imprint of the thorax(?).

Another part of the rock contained this imprint. So all in all the rock had evidence of maybe four Dalmanites trilobites.

Here is an interesting link to someone in Indiana that has found some very nice trilobite fossils. He claims his fossil "the best Dalmanites ever to be found in the Waldron Shale Formation."

Fossilized Fern Leaves

Here is a picture of some fossilized fern leaves. They are in an exhibit case but no name or place is on the exhibit. The next picture shows some sort of inventory marker which might be of use later. The picture was take at the Louisville Science Center on the 2nd floor.

Snail Called Turbinopsis shumardi

Volunteered at the Louisville Science Center again and even though it was NanoDay I was able to take a few fossil pictures. Here is one of a gastropod (snail) in the a display case on the 2nd floor near the window looking out over the Ohio River. It is a Devonian snail called Turbinopsis shumardi and I am guessing it was found in Louisville, Kentucky in the Jeffersonville Limestone. It seemed to be about 10-20 cm in width. It appears to be a mold or cast.

Here is a link to another one found on the KYANA Geological Society website.


In the same case is a Devonian colonial coral called Favosites (Emmonsia) epidermata. I have posted this specimen before but thought I would take another picture. Here is a link to a picture of another one at the KYANA Geological Society website.
