Trilobite, mon ami
"Greenops widderensis, Widder Formation, Arkona, Ontario - A perfect 33x25 mm trilobite, with head uplifted. Superbly prepared on a 9x6x3 cm matrix with one sawn edge. I live fifteen minutes away from this famous Devonian site, but have never found one as nice. And finding them is the easy part; preparing these, with precision air abrasive tools, is a painstaking process. A great example of a critter that was cruising the ocean floor some 350 million years ago"
