Friendship Locality (MGS-129) (Cretaceous of the United States)

Where: Lee County, Mississippi (34.4° N, 88.6° W: paleocoordinates 37.3° N, 60.1° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tupelo Tongue Member (Coffee Sand Formation), Middle Campanian (83.5 - 70.6 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, glauconitic, sandy claystone

• These greensands represent more shallow and neritic environments than their leteral carbonate evivalents
• ...the prevailing chalk facies laterally grade into unconsolidated glauconitic sands or sandy clays...These data indicate that the Coffee Sand reaches a total thickness of 72 m in the area concerned; lies on the Mooreville Chalk and is overlain by the Demopolis Chalk. The top of the Chapelville fossiliferous horizon lies about 17 m above the base of the formation.

Size classes: macrofossils, mesofossils

Preservation: original aragonite
