Where: Indiana (39.5° N, 85.5° W: paleocoordinates 27.6° S, 51.5° W)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Laurel Formation, Wenlock (433.4 - 427.4 Ma)
• "Formational assignment of the strat with this community is somewhat problematic. At most outcrops, the Laurel-Waldron contact is abrupt and has low relief, even though in many places it is a hardground. At Sandusky and elsewhere it is more gradiational. The unit was termed the 'transitional beds' by Frest (1977) and assigned, somewhat arbitrarily, to the Laurel because of the mixed fauna and predominantly carbonate lithology."
• formation-level stratigraphic resolution
Environment/lithology: deep subtidal; shelly/skeletal grainstone and shelly/skeletal packstone
•SEP environmental call based on given information and knowledge of regional geology
