Magnitude and timing of peat-to-coal compaction
The peat-to-coal transition is commonly assumed to be accompanied by compaction that decreases the thickness of the organic deposit to values of 10% or less of the original peat thickness.Expand

A Diverse Dinosaur-Bird Footprint Assemblage from the Lance Formation, Upper Cretaceous, Eastern Wyoming: Implications for Ichnotaxonomy
A diverse assemblage of dinosaur and bird tracks from Niobrara County, Wyoming, represents the first vertebrate ichnofauna reported from the bone-rich Lance Formation (Maastrichtian, UpperExpand

The stratigraphy and sedimentology of the Fundy Group (Triassic) of the St. Martins area, New Brunswick
Triassic sediments exposed along the south shore of New Brunswick, near St. Martins, were deposited primarily by a series of alluvial fans prograding eastward from the western margin of the FundyExpand

Carbon isotopes support the presence of extensive land floras pre-dating the origin of vascular plants.
Abstract Multiple lines of evidence indicate that Earth's land masses became green some 2.7 Ga ago, about 1 billion years after the advent of life. About 2.2 billion years later, land plants abruptlyExpand

The Genesis and Recognition of Anastomosed Fluvial Deposits: Data from the St. Mary River Formation, Southwestern Alberta, Canada
ABSTRACT Data from modern fluvial systems show that the term anastomosed is best reserved for suspended-load systems with multiple channels and very low slope that flow in regions where theExpand

Spatial variations in tectonic subsidence during - Tippecanoe I in the Michigan Basin
Episodic tectonic subsidence can be seen from all backstripped wells from the Michigan Basin. These episodes are observed as periods of relatively rapid subsidence, contrasting with the relativelyExpand

Tectonic control of Triassic sedimentation in southern New Brunswick: Local and regional implications
Both regional and local tectonics controlled the sediment distribution in the Fundy half-graben during the Triassic. Locally, alluvial fans built out into the basin from the western boundary faultExpand

A paleopedologic and ichnologic perspective of the terrestrial Pennsylvanian landscape in the distal Appalachian Basin, U.S.A.
Abstract The Conemaugh Group of southeastern Ohio contains numerous ichnofossil-bearing paleosols in both the lower Glenshaw and upper Casselman formations, which were deposited during the KasimovianExpand

Detrital zircons and sediment dispersal in the Appalachian foreland
Seven new detrital-zircon U-Pb age analyses along with a compilation of previously published data from Mississippian–Permian sandstones in the Appalachian foreland (total n = 3564) define theExpand
