Also known as Camp Margetts

Where: Nei Mongol, China (43.7° N, 112.0° E: paleocoordinates 45.2° N, 105.7° E)

• coordinate based on nearby landmark

When: Irdinmanhan (48.6 - 37.2 Ma)

• "Upper Eocene" and presumably Irdinmanhan; correlation with the Irdin Manha Formation proper would be groundless, see Radinsky 1964
