Another view of the trilobite Trimerus delphinocephalus posted yesterday. It is from the Silurian period and was found in Clark County, Indiana (far southern part of state).

Silurian Trilobite - Trimerus delphinocephalus

My cousin has been working on a trilobite fossil found by a KYANA member in Clark County, Indiana on a field trip. It has now been sealed to help preserve the fragile shell after was cleaned with a sandblaster. This trilobite is called Trimerus delphinocephalus (Green, 1832) and lived in the Silurian Period. The matrix is from the Waldron Shale layer.
