Capay Eocene Corals, CA, I (Eocene of the United States)

Where: Yolo County, California (38.5° N, 121.6° W: paleocoordinates 42.4° N, 103.0° W)

• total number of corals is almost twice the total number of molluscs

•prolific abundance of Trochocyathus indicates tropical waters and a depth of at least 366 meters

• ..gray shales exposed in a canyon

Size class: macrofossils
