Also known as Fagerstrom #12

Where: Ontario, Canada (44.0° N, 81.3° W: paleocoordinates 37.0° S, 27.7° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Formosa Reef Limestone Member (Amherstburg Formation), Eifelian (393.3 - 387.7 Ma)

• Not explicitly stated as Emsian in this ref; however, it is in Ludvigsen (1986). [JA: the Formosa Reef Limestone is actually Eifelian, see Edinger et al. 2002]
