Trimerus delphinocephalus
Waldron Shale Formation
Clark County, IN
Silurian
Here is an ultra rare
and extremely aesthetic trilobite from a new road cut location in southern
Indiana. This trilobite, Trimerus delphinocephalus,
measures 3 1/2" long and is laid out almost perfectly on a natural piece
of matrix. This specimen, as far as I know, is the only known complete
Trimerus from the Waldron Shale. It has outstanding preservation and
also happens to be extremely 3-D. This has to be one of the most sought
after trilobites from the Waldron Shale. A true museum quality trilobite!!
