Extra details from original publication
Remarks: The distinctive feature of Rugotruncana skewesae, n. sp., is its very flat dorsal side. Globotruncana concavata (Brotzen) is the only globotruncanid known to us to have flatter dorsal side. Plummer (1927) referred R. skewesae, n. sp., to Globigerina rosetta Carsey. It differs from Causey's species in possessing faint costellae on the ventral side, rather strong spines on the keels of the early chambers of the last whorl, and a much flatter dorsal side. The holotype of Rugotruncana skewesae, n. sp., is from the same locality as the specimen figured by Plummer. It has been observed in the Prairie Bluff chalk in Alabama.
Range: Maastrichtian.
