Arborescent lycopsid productivity and lifespan: Constraining the possibilities

Boyce, C. K.; DiMichele, William A. (2016)

One of the most enigmatic components of early terrestrial vegetation was the arborescent lycopsids. Because of the sheer abundance of their biomass in many wetland environments of the Late Paleozoic, they may have been an ...

Atlas of Selected Kinney Quarry Plant Fossils, Late Pennsylvanian, Central New Mexico

Donovan, Michael P.; DiMichele, William A.; Lucas, Spencer G.; Schneider, Joerg W. (2021)

During the Late Pennsylvanian, seasonality and rainfall increased in western Pangea, which led to the expansion of "mixed" floras composed of a combination of wetland and drought-tolerant plants. One notable example is the ...

Autocyclic and allocyclic controls on the origin of the Dunkard Group

Calamitalean "pith casts" reconsidered

DiMichele, William A.; Falcon-Lang, Howard (2012)

Sediment-cast calamitalean axes in growth position are one of the most common fossils in the Pennsylvanian coal measures. In this paper, we challenge the long accepted position that these fossils represent "pith casts". ...

Callipterid peltasperms of the Dunkard Group, Central Appalachian Basin

DiMichele, William A.; Kerp, Hans; Sirmons, Roberta; Fedorko, Nick; Skema, Viktoras; Blake, Bascombe M., Jr.; Cecil, C. B. (2013)

Abstract The Dunkard Group is the youngest late Paleozoic rock unit in the Central Appalachian Basin. Its age, however, remains controversial. In its southern and western two-thirds the Dunkard is comprised largely of red ...

Cataclysmic burial of Pennsylvanian Period coal swamps in the Illinois Basin

Archer, Allen W.; Elrick, Scott; Nelson, W. J.; DiMichele, William A. (John Wiley & Sons, Ltd, 2016)

Catastrophically Buried Middle Pennsylvanian Sigillaria and Calamitean Sphenopsids from Indiana, Usa: what Kind of Vegetation was This?

DiMichele, William A.; Nelson, W. John; Elrick, Scott; Ames, Philip R. (2009)

A catastrophically buried stand of calamitean sphenopsids and sigillarian lycopsids is reported from the Middle Pennsylvanian of southwestern Indiana, in the Illinois Basin. The plants were exposed in the highwall of a ...

DiMichele, William A.; Philips, T. L. (1996)

Climate and vegetational regime shifts in the late Paleozoic ice age earth

DiMichele, William A.; Montañez, I. P.; Poulsen, C. J.; Tabor, Neil J. (2009)

The late Paleozoic earth experienced alternation between glacial and non-glacial climates at multiple temporal scales, accompanied by atmospheric CO2 fluctuations and global warming intervals, often attended by significant ...

Climate change, plant extinctions, and vegetational recovery during the Middle-Late Pennsylvanian transition: the case of tropical peat-forming environments in North America

DiMichele, William A.; Philips, T. L. (1996)

Climate, pCO2 and terrestrial carbon cycle linkages during late Palaeozoic glacial-interglacial cycles

Montañez, Isabel P.; McElwain, Jennifer C.; Poulsen, Christopher J.; White, Joseph D.; DiMichele, William A.; Wilson, Jonathan P.; Griggs, Galen; Hren, Michael T. (2016)

Earth's last icehouse, 300 million years ago, is considered the longest-lived and most acute of the past half-billion years, characterized by expansive continental ice sheets and possibly tropical low-elevation glaciation. ...
