Also known as Trinacromerum bentonianum type
Where: Mitchell County County, Kansas (39.4° N, 98.5° W: paleocoordinates 39.9° N, 63.5° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Fairport Member (Carlile Shale Formation), Middle Turonian (93.5 - 89.3 Ma)
• "The geologic map of Landes (1930) shows that the only geologic unit exposed in this vicinity is the Fairport Chalk. This matches well with Cragin's (1888) description of the geology, as a few feet below the base of the dark septaria-bearing shale (Blue Hill) is equivalent to within the Fairport Chalk Member of the Carlisle Shale. The age of this specimen is early Middle Turonian" (Schumacher & Everhart 2005, p. 40).
• bed-level stratigraphic resolution
Environment/lithology: marine; limestone
Size class: macrofossils
Reposited in the UNSM
