The areas around the Green River in Wyoming, Colorado and Utah were covered by several large freshwater lakes between 55 and 37 million years ago. These ancient lakes provided ideal conditions for fossilization, and contain some of the most diverse and abundant fossil deposits of fishes from freshwater habitats in the last 66 million years. These fossil deposits not only paint a vivid image of the lake ecosystem, but they also provide an important glimpse into the diversity of North American freshwater fishes during the Eocene.


The Yale Peabody Museum collections contain a significant representation of the Green River fish fossil diversity. Rich Harrington will discuss the fishes of the Green River fossil deposits and their significance to our understanding of the origins of the modern North American freshwater fish fauna.
