Stratigraphy
Stratigraphy comments: The geologic map of Berry (1952) depicts exposures of the Carlile Shale and lower horizons in this area. Uncrushed preservation (lack of compaction) suggest burial in a bioturbated chalky limestone unit, which tend to produce more three-dimensional specimens. Thus the specimen likely cocured in limestone beds of the Greenhorn Limestone or the Fairport Chalk, and is Middle Cenomanian to Middle Turonian in age" (Schumacher & Everhart 2005 p. 47). |
