Trimerus delphinocephalus Trilobite

Here is a trilobite found by a KYANA Geological Society ( member on a field trip some years ago. It is a Trimerus delphinocephalus (Green) from the Silurian Period. It was found in the Waldron Shale layer in Clark County, Indiana.

This image shows the trilobite in two pieces: part of the head and thorax/back. Maybe it was a molt. See this link for different picture of this same specimen:

Here is a link that shows another from the same area but it appears fully intact:
