Description

Fine Knightia Fish Plate from one of the world's famous Laggerstatten, the Green River Formation in Wyoming. A small portion of the fish fossils from Green River exhibits such fine preservation. The significant extent of soft-tissue preservation that makes the site famous is evident in this specimen

Condition Report

Exceptional and well exposed detail, such as the vertebrae can be seen impeccably. Excellent Bone tissue, and overall specimen, [complete/intact specimen, beautifully and naturally position on Limestone Bed]. The head and Jaw/Mouth area shows exceptional and distinct detail also; excellent preservation to all the key characteristics and features, helping to distinguish this particular Genus of Knightia, relative of the less robust type of Eocene Fish, the Knightia eocaena.

Great state of preservation, this plaque specimen is one of few available, as fossil fish plaques of this quality are declining more and more every year, on the fossil sites, and in the Fossil trade

Genus

Knightia Alta Fossil Fish sp.

Geological Age

Cenozoic Era Tertiary; Paleogene Sub-Periods, Early [Lower] Eocene Epoch, Ypresian Stage, around 48-55 million years ago

History of the Green River Formation

The Green River Formation represents one of the largest documented accumulations of sedimentary rock in the world and dates back 50 million years. It covers an area of more than 25,000 square miles and averages about 2000 feet in thickness. These lakes were formed by geologic events that uplifted the Rocky Mountains in early times. The climate was much different than the desert like climate of today. It was similar (subtropical) to the present climate of the Gulf Coast and southern Atlantic areas of the US. The first record of a fossil fish discovered in the Green River Formation was in 1856. All of the fossil fish, stingrays, palm fronds and others displayed on our web site come from the Fossil Lake area near Kemmerer, Wyoming USA. Found at the 7200 foot elevation this area has been commercially mined since the late 1800 hundreds
