Fossil burrows within newly recognized buried soils in the Late Ordovician Juniata Formation, near Potters Mills in central Pennsylvania, represent the oldest reported nonmarine trace fossils. They are thought to have been an original part of the soil because their greater density toward the top of the paleosols corresponds with mineralogical, microstructural, and chemical changes attributed to ancient weathering and because about half the burrows are encrusted with nodular carbonate… Expand
Scoyenia burrows from Ordovician palaeosols of the Juniata Formation in Pennsylvania
Scoyenia beerboweri is a new ichnospecies of burrow from the late Ordovician (Ashgill) Juniata Formation in central Pennsylvania, USA. The burrows are abundant in red calcareous palaeosols, and wereExpand

Abstract The Juniata Formation comprises Upper Ordovician sandstone and mudstone that crops out in the Appalachian region of the eastern United States from Pennsylvania to Tennessee. An outcrop atExpand
The potential of paleozoic nonmarine trace fossils for paleoecological interpretations
Abstract Many Late Paleozoic environments have been interpreted as marine because of the co-occurrence of supposedly exclusively marine trace fossils. Beginning in the Late Ordovician, however,Expand
Early Paleozoic colonisation of the land – evidence from the Tumblagooda Sandstone, Southern Carnarvon Basin, Western Australia.
The early Paleozoic Tumblagooda Sandstone outcrops principally in the vicinity of the Murchison River in Kalbarri National Park, Western Australia. It contains a great variety of trace fossils thatExpand
Cambrian to Devonian evolution of alluvial systems: The sedimentological impact of the earliest land plants
Abstract In present-day alluvial environments, the impact of vegetation on sedimentological processes and deposits is well known. A vegetated catchment may decrease sediment yield, sedimentExpand
Early Silurian nonmarine animal remains and the nature of the early continental ecosystem
An assemblage of animal remains, the oldest from undoubted nonmarine beds, with structures attributable to at least one possible terrestrial animal, has been recovered in deposits of Early Silurian,Expand
Early Forest Soils and Their Role in Devonian Global Change
TLDR
From Silurian into Devonian time, red clayey calcareous paleosols show a greater volume of roots and a concomitant decline in the density of animal burrows, which parallel the decline in atmospheric carbon dioxide determined from isotopic records of pedogenic carbonate in these same paleosol.

Evolution and ecology of Neoproterozoic-Lower Cambrian trace fossils, NW Canada
Neoproterozoic to subtrilobite Cambrian strata in the Mackenzie Mountains, Canada, provide a test case for the current paradigm of evolutionary stages in the development of the early infauna. ThreeExpand
Late Ordovician Glaciation Initiated by Early Land Plant Evolution and Punctuated by Greenhouse Mass Extinctions
Late Ordovician (Hirnantian) glaciation, indicated by periglacial paleosols, tillites, and glacial pavements in Saharan Africa, has been attributed to advances in weathering and carbon sequestrationExpand
Terrestrialization (Precambrian–Devonian)
TLDR
The emergence of plants and animals from the sea on to land – terrestrialisation – was one of the major advances in the history of life on Earth, but it was not until the latest Palaeozoic that modern-type terrestrial ecosystems, with abundant herbivores in the food chain, came. Expand

TLDR
Energy costs incurred by plants producing anti-herbivore and anti-detritivore defences have therefore probably been significant in ecosystems since the Devonian, and Mamayev's gravitational hypothesis provides an explanation for evolution of hexapody from uniramians clambering up and over early land plants.

TLDR
The interval from the mid Ordovician to the mid-late Early Silurian is hypothesized on the basis of the abundant and widespread spore records to be one of rapid colonization by founder populations with limited genetic diversity and with life-history strategies that included an ecophysiological tolerance to desiccation and a short vegetative life cycle.

TLDR
It is concluded that the lack of well preserved and independently dated assemblages from elsewhere in the world prevents the detection of any provincialism in the late Silurian and early Devonian and makes generalizations on the early history of vascular plants premature. Expand
