This is a 380-million year old, enrolled Eldredgeops trilobite from the famous Windom Shale in Erie County, Western New York State. The trilobite is spectacularly detailed, with the original carapace (shell) beautifully preserved by replacement with black calcium phosphate. The trilobite is complete, in a rolled position. The multi-lensed eye on this specimen is beautifully preserved.
Prior to about 1990, these North American trilobites were identified as the genus Phacops, but differences in morphology around the eye were recognized compared to the Phacops trilobites of Morocco, and the North American "Phacops” trilobites were redesignated as the genus Eldredgeops.
This specimen is in the original Windom Shale matrix. The piece was collected and prepared by Paul & Jane Bembia.
Trilobite approximately 15 x 14 mm. Entire specimen is 73 x 37 x 7 mm. 18 grams total.
