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."
