Near Alton [FHSM VP-2149] (Cretaceous of the United States)

Where: Osborne County County, Kansas (39.5° N, 98.9° W: paleocoordinates 40.1° N, 63.9° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Fairport Member (Carlile Shale Formation), Middle Turonian (93.5 - 89.3 Ma)

• The specimen shows signs of crushing due to burial in shaly chalk, while nearly all of the Fort Hays Limestone is massive, bioturbated chalk, which generally preserved more three-dimensional specimens. Thus, the specimen is probably from the Carlisle Shale, and the carbonate matrix suggests it comes from the Fairport Chalk Member.
