Abstract The late Paleozoic Ice Age (LPIA) was one of Earth's most important Phanerozoic
climatic events lasting for over 100 Mys. Despite its importance, its history is controversial …

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

Icehouses are the less common climate state on Earth, and thus it is notable that the longest-
lived (c. 370 to 260 Ma) and possibly most extensive and intense of icehouse periods …

Several positive carbon isotope excursions in Lower Paleozoic rocks, including the
prominent Upper Cambrian Steptoean Positive Carbon Isotope Excursion (SPICE), are …

Detrital zircon U‐Pb data are routinely used to assess provenance in sedimentary systems.
However, recent studies have suggested that zircon provenance interpretation may be …

Rugose corals are one of the major fossil groups in shallow-water environments. They
played an important role in dividing and correlating Carboniferous strata during the last …

Variability in stratigraphic accumulation rates and distribution of stratal hiatuses along with
strong endemism of index fossils hinder regional to global stratigraphic correlation of the …

Middle Carboniferous carbonates in the western US have undergone Pleistocene Bahamas‐
style meteoric diagenesis that may be associated with expanding late Paleozoic ice sheets …

The Steptoean positive carbon isotope excursion (SPICE) event, one of the largest carbon
cycle perturbations in the Cambrian, coincides with shallow-shelf-fauna extinction and …

We describe, interpret, and establish a stratotype for the Frenchman Mountain Dolostone
(FMD), a new Cambrian stratigraphic unit that records key global geochemical and climate …
