Cleaned Silurian Trimerus Trilobite

This Trimerus delphinocephalus (Green, 1832) trilobite has been prepped using a dental tool and toothbrush. This particular picture has been touched up with Adobe Photoshop to fill in the missing areas of the fossil. Most of the work was done to the front scoop on the cephalon and the sides of the pygidium (tail). Also cracks in the thorax plates and areas where the eyes were placed are covered in brown.

Fossil was found in the Waldron Shale of Clark County, Indiana, USA. It dates to about 419 million years ago which is the Silurian Period.

This next image is a close up of the thorax segments on the side of the fossil. The detail of the texture on the plates is nice. A series of small bumps can be seen, maybe these served as some sort sensory system.

This last series of pictures show the fossil from different angles. Thanks to Kenny for prepping this fossil!
