From Wetlands to Wet Spots: Environmental Tracking and the Fate of Carboniferous Elements in Early Permian Tropical Floras

  title={From Wetlands to Wet Spots: Environmental Tracking and the Fate of Carboniferous Elements in Early Permian Tropical Floras},
  author={William A. DiMichele and Neil J. Tabor and Dan S. Chaney and W. John Nelson},
Diverse wetland vegetation flourished at the margins of the Midland Basin in north-central Texas during the Pennsylvanian Period. Extensive coastal swamps and an ever-wet, tropical climate supported lush growth of pteridosperm, marattialean fern, lycopsid, and calamite trees, and a wide array of ground cover and vines. As the Pennsylvanian passed into the Permian, the climate of the area became drier and more seasonal, the great swamps disappeared regionally, and aridity spread. The climatic… Expand
Analysis of climate and landscape change through the Pennsylvanian and Permian Monongahela and Dunkard Groups, Southeastern Ohio, USA
Paleosols and ichnofossils of the Late Pennsylvanian to Early Permian Monongahela and Dunkard groups of southeastern Ohio provide significant paleoenvironmental and paleoclimatic data related to theExpand
The environmental implications of upper Paleozoic plant-fossil assemblages with mixtures of wetland and drought-tolerant taxa in tropical Pangea
Abstract We evaluate the influences of elevation and climate on the spatio-temporal distribution of wetland and dryland biomes during the Pennsylvanian and early Permian in tropical Pangea. TheExpand
A 25 million year macrofloral record (Carboniferous–Permian) in the Czech part of the Intra-Sudetic Basin; biostratigraphy, plant diversity and vegetation patterns
Abstract The Intra-Sudetic Basin is essentially a post-orogenic (Variscan) continental basin with a depositional history that ranges from the late Visean to the Triassic. The fossil record in theExpand
Palynological evidence for Pennsylvanian extra-basinal vegetation in Atlantic Canada
Abstract: Pollen preserved in latest Westphalian and early Stephanian clastic deposits of the Sydney Coalfield, Cape Breton Island, suggest that there were zones of different vegetational habitatsExpand
Early Permian (Asselian) vegetation from a seasonally dry coast in western equatorial Pangea: Paleoecology and evolutionary significance
Abstract 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 theExpand
Dryland vegetation from the Middle Pennsylvanian of Indiana (Illinois Basin): the dryland biome in glacioeustatic, paleobiogeographic, and paleoecologic context
Abstract A macrofloral assemblage dominated by elements of the Euramerican dryland biome is described from the Brazil Formation in Clay County, Indiana (Illinois Basin). Fossils were recovered from aExpand
Paleoecological and paleoenvironmental interpretation of three successive macrofloras and palynofloras from the Kola Switch locality, lower Permian (Archer City Formation, Bowie Group) of Clay County, Texas, USA
The palynofloras, although varying between and even within the beds, indicate a common background species pool during the time interval sampled, suggesting that these distinct floras reflect local changes in microhabitat conditions under a constant climatic background. Expand
Wetland-Dryland Vegetational Dynamics in the Pennsylvanian Ice Age Tropics

Lower-diversity worlds such as the late Paleozoic, with a rich spectrum of environmental variations, offer insights into relationships between organisms and environments that expand understanding of these phenomena and enlarge their sense of what is possible or probable as the authors look to the future.

Palaeoclimatic and site-specific conditions in the early Permian fossil forest of Chemnitz—Sedimentological, geochemical and palaeobotanical evidence
Abstract As significant indicators of deep-time palaeoclimate, a number of new palaeontological, pedological and geochemical characteristics are provided for the Chemnitz Fossil Lagerstatte to depictExpand
Pennsylvanian-Permian vegetational changes in tropical Euramerica
Vegetational changes across the Pennsylvanian-Permian boundary are recorded in several largely terrestrial basins across the Euramerican portions of equatorial Pangea. For the purposes of this paper,Expand


The similarities of the marine and terrestrial patterns suggest that the combination of evolutionary opportunity, created by physical heterogeneity of the environment, and migrational opportunity,created by changing extrinsic conditions, may be underlying factors that transcend the specifics of organism and environment.

An early Pennsylvanian waterhole deposit and its fossil biota in a dryland alluvial plain setting, Joggins, Nova Scotia
The terrestrial ecology of Pennsylvanian tropical wetlands is understood in detail, but coeval dryland ecosystems remain highly enigmatic. To fill this gap in our knowledge, a PennsylvanianExpand
Paleobotanical and paleoecological constraints on models of peat formation in the Late Carboniferous of Euramerica
Abstract The dominant plants of the Late Carboniferous lowland tropics were taxonomically and structurally distinct from those of any later time periods. Dominance was distributed among lycopsids,Expand
Soil chronosequence studies in temperate to subtropical, low-latitude, low-relief terrain with data from the eastern United States
The Coastal Plain of the eastern United States is a low-latitude, low-altitude, low-relief terrain composed primarily of gently dipping marine and marginal-marine sediments that range in age fromExpand
An Early Permian plant assemblage from the Taiyuan Formation of northern China with compression/impression and permineralized preservation.
The permineralized assemblage at Yangshuling represents the first example of anatomically preserved plants from volcaniclastic lithologies from the Palaeozoic of China, raising the possibility of similarly preserved plant-fossil assemblages elsewhere in the Cathaysian realm. Expand

Abstract The Orinoco Delta in eastern Venezuela is an excellent modern analog for Upper Carboniferous depositional environments in terms of climate, physiography, sedimentology, and the presence ofExpand
Implications of an exceptional fossil flora for Late Cretaceous vegetation
THE rapid radiation of angiosperms during the Late Cretaceous has been thought to reflect their rise to vegetational dominance1–3. The number of species in a clade and its vegetational importance areExpand
