Because of the basinal location of the ''Glob alt'' depositional thick, the biofacies are typically bathyal. In this setting, the subsandstone interval has upward-decreasing fossil abundance away from the fossil abundance peak in the underlying condensed section. This pattern suggests increased rates of sediment accumulation vs. biotic productivity, interpreted as signals of falling sea level. Conversely, the supersandstone interval typically has upward-increasing fossil abundance toward the overlying condensed section. This pattern suggests decreased rates of sediment accumulation vs. biotic productivity and is interpreted as a signal of rising sea level and consequent sediment starvation at the sample site. The sandstone interval typically has few fossils, and those few may reflect very shallow water depths due to downslope transport of the sand by gravity-flow processes. Data from shelf environments have a different set of interpretation criteria <ref name=ch04r10>Armentrout, J., M., Clement, J., F., 1990, Biostratigraphic calibration of depositional cycles: a case study in High Island–Galveston–East Breaks areas, offshore Texas: Proceedings, Gulf Coast Section SEPM 11th Annual Research Conference, p. 21–51.</ref><ref name=ch04r9>Armentrout, J., M., 1996, High-resolution sequence biostratigraphy: examples from the Gulf of Mexico Plio–Pleistocene, in Howell, J., Aiken, J., eds., High Resolution Sequence stratigraphy: Innovations and Applications: The Geological Society of London Special Publication 104, p. 65–86.</ref>
