Wetland forests, known as coal forests, extended over large areas of the palaeotropics during the Late Carboniferous and the Permian Periods. They were initiated during the Serpukhovian Age as a response to lowering sea levels having exposed large areas of continental shelf. They expanded dramatically during the late Bashkirian Age, but then contracted by over one‐half during the Kasimovian Age. The estimated loss of carbon sink probably resulted in an annual increase in atmospheric CO2 of… 
Impact of an icehouse climate interval on tropical vegetation and plant evolution
Complex plant ecosystems first experienced the effects of major glaciation during the Late Paleozoic Ice Age. The general response of Carboniferous tropical vegetation to these climatic fluctuations,
Strontium and carbon isotopic evidence for decoupling of pCO2 from continental weathering at the apex of the late Paleozoic glaciation
Earth’s penultimate icehouse (ca. 340–285 Ma) was a time of low atmospheric pCO2 and high pO2, formation of the supercontinent Pangaea, dynamic glaciation in the Southern Hemisphere, and radiation of
Pennsylvanian tropical floras from the United States as a record of changing climate
Late Carboniferous (Pennsylvanian) fossil fl oras from the United States are well studied as adpression, permineralization, and palynomorph assemblages throughout the stratigraphic column. These data
Constraining the Timing and Amplitude of Early Serpukhovian Glacioeustasy With a Continuous Carbonate Record in Northern Spain
During the Late Paleozoic Ice Age (LPIA, 345–260 Ma), an expansion of ice house conditions at ∼330 Ma caused a nearly synchronous, global unconformity. Subaerially exposed paleotropical carbonates
Trends and Rhythms in Climate Change During the Early Permian Icehouse
Late Paleozoic deglaciation is the first icehouse‐to‐greenhouse transition in a world with expansive tropical forests, but the detailed process of this climatic upheaval is still debated due to lack


Out of the Icehouse into the Greenhouse: A Late Paleozoic Analogue for Modern Global Vegetational Change
A change to global greenhouse conditions following deglaciation occurred during the late Paleozoic. The deep-past data set preserved in the stratigraphic record can serve as a model system to
The Ending of the Late Paleozoic Ice Age During the Permian Period
The climate on Earth has varied between times of coolness accompanied by widespread continental glaciation and times of relative warmth when glaciers disappeared except in mountainous regions. This
Polar glaciation and the genesis of ice ages

One of the outstanding, unresolved climatic questions concerns the cause(s) of ice ages over geological time1,2. A recurring theme in many hypotheses2–4 has been that land at high latitude is a
The Early Carboniferous (Asbian-Brigantian) seasonal tropical climate of northern Britain
Northern Britain lay close to the equator during the Early Carboniferous and evidence, primarily from paleosols and predictions from climate models, indicates that it experienced a seasonal climate,
Patterns of late Palaeozoic deglaciation in the Paraná Basin, Brazil
Namurian uplift in Australia and South America triggered the main Gondwanan glaciation
The Permo-Carboniferous glacigenic sediment at the base of the Gondwanan basins reflects the culmination1,2 of the glacial episode that started in Australia and southern South America in the
Migration of glacial centers across Gondwana during Paleozoic Era
Continental glaciation, as recorded by sedimentary facies and by pavements scoured into underlying rocks, affected northern Africa at the end of the Proterozoic Era. This glaciation was followed in
Development of the Late Paleozoic glaciations of the South American Gondwana in western Argentina
SUMMARY The Gulf Coast plain of S.E. U.S.A. is suggested as a modern analogue of the Carboniferous shelf across Britain. The coastal plain has developed over a comparable period to the shelf, they
On the periodicity and magnitude of Late Carboniferous glacio-eustatie sea-level changes
Data from sedimentary cycles in basins from northern England, the Appalachians and Midcontinent US afford an insight into periodicities and controls of Late Carboniferous glacio-eustatic sea-level
