Middle Devonian to Late Mississippian event stratigraphy of Overthrust belt region, western United States Middle Devonian to Late Mississippian event stratigraphy of Overthrust belt region, western United States
Twenty eustatic and epeirogenic events mainly dated by conodonts are distinguished between the Middle Devonian and the lower Upper Mississippian in Great Basin, in Rocky Mountains and in the Overthrust belt regions.

Devonian eustatic fluctuations in Euramerica Devonian eustatic fluctuations in Euramerica
The Devonian System of Euramerica contains at least 14 transgressive-regressive (T-R) cycles of eustatic origin. These are separated into three groups (or depophases) and from Carboniferous cycles by three prominent regressions. Twelve post-Lochkovian T-R cycles are recognized, and they commonly appear to result from abrupt deepening events followed by prolonged upward shallowing...

Late Devonian icriodontid biofacies models and alternate shallow-water conodont zonation Late Devonian icriodontid biofacies models and alternate shallow-water conodont zonation
Recognition of differences in the habitats, apparatuses, and ranges of Late Devonian Icriodus and Pelekysgnathus permits refinement of their biofacies interpretations and construction of an alternate icriodontid zonation. Icriodus is a euphotic genus that predominated in most environments during the early Late Devonian (Frasnian) but died out during the early Famennian. Its apparatus...
