Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

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 …

The processes of geologic preservation are important for understanding the organisms
represented by fossils. Some fossil differences are due to basic differences in organization …

Publisher Summary Every fossil represents evidence that an organism lived, not in isolation,
but in the context of a physical setting populated by other organisms. To understand the …

The exceptional preservation of plant fossils falls into two categories: whole plant
preservation and anatomical detail. Whole plant preservation is controlled primarily by …

Coal balls (exceptionally preserved calcareous permineralized peat), widely described from
tropical Carboniferous Euramerian coal seams, have yielded diverse data on the biology …

Silicified peat is known from two sites in the central Transantarctic Mountains. Both are
within a 2-km-thick Permo-Triassic sandstone-shale sequence that was deposited by …

Lagenostomalean-type seeds in bifurcating cupule systems have been discovered in the
late Devonian Hampshire Formation of Randolph County, West Virginia, USA (Fig. 1). The …

A review of coal-ball floras from Central and Western Europe is presented with special
attention to recent studies of coal balls from England and Spain. Emphasis is placed on the …

Cordaiteans in cordaite-dominated permineralized peat from Pennsylvanian coals in Iowa
have been reconstructed as mangroves using root anatomy, peat taphonomy, and …
