LARGE AND RARE FOSSIL DOGFISH
Amia pattersoni, Knightia eocaena
Eocene
Green River Formation, Lincoln Co, Wyoming
Of all the nineteen genera of fish to be found in the abundant fossil beds of the Green River Formation, one of the very rarest is the Amia; a prehistoric relative of the modern bowfin. These large fish could grow to over four feet long and were bottom feeders and scavengers; distinguished by the dorsal fin that ran almost the entire length of their body. The fossils from this region are renowned for their quality and the present example is no exception: superb three-dimensionality is visible throughout, from the thick heavy bones of the head and the mouth bristling with pointed vicious-looking teeth, many prepared entirely free from the matrix, to the robust spinal column and slender ribs, even down to the tiny bones of the fins. Almost the entire body is covered with well-preserved scales of rounded-off rectangular shape. The Amia itself measures 45½ inches in length, amongst the larger of the Amia found there, and are joined in the matrix by a good handful of the small herring Knightia, abundant and characteristic denizens of the sub-tropical lake system of over 50 million years ago. The fossils have a lovely soft pale caramel coloring that harmonizes perfectly with the irregularly-shaped creamy limestone matrix, 42 x 66½ inches.
