About The Fossil Images

None of the images on the Cincinnati Trilobite Fragment Identifier are photographs. The fossils were scanned directly into the system with a 256 grey scale hand scanner at 400 dpi. The grey scale devices get better resolution than even a 600 dpi color scanner, and they cost less! Even the large Isotelus trilobite replica was directly scanned.

Simply place the specimens on top of a sheet of glass and run the scanner underneath it just as a flat bed scanner would do. I cut the top and side off of a cardboard box and taped the glass to the top of the box. You can get the glass from an inexpensive picture frame. The results are achieved amazingly fast. No film developing costs or time. This is just the thing for fast pace of computer applications such as web pages and the cataloging of your fossil collection.

Give this a try! It is well worth the effort.

About The Specimens In The Images

The trilobite fragments shown on these Web pages are from the collections of the Dry Dredgers, an association of amateur geologists and fossil collectors. The whole trilobites shown on the anatomy charts for trilobites Flexicalymene meeki and Isotelus maximus are replicas. The Flexicalymene replica was built by Hank and Laura Barton, Dry Dredger members. The Isotelus replica was built by an unknown individual, but the original specimen was found by Dan Cooper, a world famous Dry Dredger member.
