研究了科罗拉多高原南部Cenomian-Turung期边界细粒粘土占优势的地层的岩性、碳酸盐和有机碳地球化学以及软体动物。对这些数据的分析表明，盆地和陆上到近海的沉积学和软体动物组合趋势发生了变化，这些变化贯穿于上Cenomania Sciponocera gracile和Neercocera Judii和下都灵Watinoera Coloradoense生物带。
Lithology, carbonate and organic carbon geochemistry, and molluscan macrofauna were investigated in fine-grained clay-dominated strata spanning the Cenomanian-Turonian Stage boundary in the southern Colorado Plateau region. Analyses of these data show basinal and onshore to offshore changes in sedimentologic and molluscan assemblage trends through the upper Cenomanian Sciponoceras gracile and Neocardioceras juddii and lower Turonian Watinoceras coloradoense Biozones.
