Location: Green River Formation, Wyoming, USA Time Period: Eocene
The Green River formation in the USA covers an area over 25,000 square miles and is more than 2,000 feet in thickness. This formation, dating back more than 50 million years, is one of the largest documented accumulations of sedimentary rock in the world. At the time, the area was sub-tropical and many different species flourished. This species lived in schools and were an abundant food source for larger predatory fish. Knightia is in the same family as herring and sardines.
