(2015)The Pennsylvanian-Permian transition has been inferred to be a time of significant glaciation in the Southern Hemisphere, the effects of which were manifested throughout the world. In the equatorial regions of Pangea, the ...

Nelson, W. John; Elrick, Scott D.; DiMichele, William A.; Ames, Philip R. (2020)For more than 40 years, geologists have understood that the thickness and quality of the Springfield Coal are intimately related to the Galatia channel, a paleochannel that existed contemporaneously with peat deposition. ...

Calder, John H.; Nelson, W. John; Bashforth, Arden R.; Wittry, Jack; Elrick, Scott D.; DiMichele, William A. (2023)Four collections of Middle Pennsylvanian plant fossils create an opportunity to examine a transect from below the Colchester Coal through the roof shale of the Cardiff (Survant) Coal of the Illinois Basin. The collections ...

DiMichele, William A.; Bateman, Richard M.; Rothwell, Gar W.; Duijnstee, Ivo A. P.; Elrick, Scott D.; Looy, Cynthia V. (2022)Rhizomorphic lycopsids constitute the most derived lycophyte clade and some of the world's best-known plant fossils. Arboreous taxa within the clade evolved independently of other nonlycophyte trees. Their rootstocks ...

DiMichele, William A.; Eble, Cortland F.; Pfefferkorn, Hermann W.; Elrick, Scott D.; Nelson, W. J.; Lucas, Spencer G. (2023)A threshold-like vegetational change in tropical wetlands occurred in the early Kasimovian (the US Desmoinesian–Missourian boundary) – Event 3. Two earlier significant changes occurred, first in the mid-Moscovian ...

Cecil, C. Blaine; DiMichele, William A.; Elrick, Scott D. (2014)The Pennsylvanian portion of the Late Paleozoic Ice Age was characterized by stratigraphic repetition of chemical and siliciclastic rocks in the equatorial regions of the Pangean interior. Known as "cyclothems", these ...

Falcon-Lang, Howard; John Nelson, W.; Heckel, Philip H.; DiMichele, William A.; Elrick, Scott D. (2018)The first phase in the stepwise collapse of the Carboniferous Coal Forests occurred near the Desmoinesian-Missourian boundary (early Kasimovian, ~ 307 Ma), and involved extirpation of Lycospora-producing lepidodendrids, ...

DiMichele, William A.; Eble, Cortland F.; Nelson, W. John; Pfefferkorn, Hermann W.; Elrick, Scott D. (2023)The Corinth Coal bed is a recently recognized stratigraphic unit in the lower part of the Upper Pennsylvanian Patoka Formation of the Illinois Basin, located between the underlying Chapel Coal and overlying Womac Coal in ...

Cecil, C. Blaine; DiMichele, William A.; Rahl, Jeffrey M.; Dulong, Frank T.; Michel, Lauren; Elrick, Scott D. (2023)Two lithologically distinctive Mississippian facies tracts (MFTs) are described from Lower and Middle Mississippian strata (Kinderhookian and Osagean North American Stages) in southeast Laurentia (SEL). The MFTs extend ...

Nelson, W. John; DiMichele, William A.; Wilson, Bob; Wilson, Doug; Lakeram, Scott R.; Elrick, Scott D. (2022)The remains of fossilized cordaitalean trees were discovered in the middle of the 20th century in surface and underground mines in south-central Iowa, in the vicinity of the town of Knoxville. With some uncertainty, the ...

(2023)We present the first analysis of vegetational change in far western equatorial Pangaea (New Mexico, USA) during the Middle–Late Pennsylvanian transition (determined by conodonts and fusulinids) of the Late Paleozoic Ice ...
