Gymnospermous secondary xylem degraded by wood-decaying fungi was examined in silicified fossils from Antarctica. Araucarioxylon-type wood from the Triassic and specimens of Vertebraria from the Permian demonstrate similar patterns of decay. Specimens are characterized by irregularly shaped areas lacking cells and are infected with branched, septate hyphae with clamp connections. The decay in these fossils is comparable in appearance to present-day rots caused by basidiomycetes. Two patterns of… Expand
Evidence of fungal decay in petrified legume wood from the Neogene of the Bengal Basin, India.
Silicified fossil legume woods of Cynometroxylon Chowdhury & Ghosh collected from the Neogene (late Miocene) sediments of the Bengal Basin, eastern India, exhibit fungal decay seldom found in theExpand
Wood decay of Xenoxylon yunnanensis Feng sp. nov. from the Middle Jurassic of Yunnan Province, China
Abstract A permineralised gymnosperm wood, Xenoxylon yunnanensis Feng sp. nov., is described from the Middle Jurassic Shaximiao Formation in Huize County, Yunnan Province, Southwest China. TheExpand
Marine and terrestrial invertebrate borings and fungal damage in Paleogene fossil woods from Seymour Island, Antarctica
ABSTRACT An assemblage of permineralized conifer and angiosperm woods collected from Paleogene marine strata on Seymour Island during the Swedish Antarctic expedition of 1901–1903 includes manyExpand
Structure and ontogeny of Vertebraria from silicified Permian sediments in East Antarctica
Silicified peat of Permian age from Amery Group sediments near Beaver Lake, East Antarctica represents a swamp dominated by Glossopteris, with little other floristic diversity. ExceptionalExpand
A POSSIBLE ENDOPARASITIC CHYTRIDIOMYCETE FUNGUS FROM THE PERMIAN OF ANTARCTICA
Several stages of the life cycle of an endoparasitic fungus of the Chytridiomycota, here assigned to the extant genus Synchtrium, are described as the new species permicus from silicified plantExpand
Plant-arthropod and plant-fungus interactions in late Permian gymnospermous woods from the Bogda Mountains, Xinjiang, northwestern China
TLDR
The fungal hyphae, coprolites, and degraded excavations in the pith of the late Permian wood suggest that wood-rotting and -boring were not limited to the xylem. Expand
A Glomalean Fungus from the Permian of Antarctica
TLDR
A new genus and species of fossil fungus, Glomorphites intercalaris, is described from silicified peat of Late Permian age from Skaar Ridge in the central Transantarctic Mountains, Antarctica, which is the first report of an endomycorrhizal‐like fungus from the Permians. Expand
A specialized feeding habit of Early Permian oribatid mites
TLDR
The absence of feeding on ambient decomposing fungi such as necroses and rots, but rather the processing of pristine plant tissues, indicate the presence of a self-contained, microorganismic gut biota in Early Permian ecosystems. Expand
Arthropod interactions with bennettitalean roots in a Triassic permineralized peat from Hopen, Svalbard Archipelago (Arctic)
Abstract Multiple thin-sections of a Late Triassic (Carnian) siliceous permineralized peat block likely derived from the De Geerdalen Formation on Hopen Island, Svalbard Archipelago, show a denseExpand
Structurally preserved fungi from Antarctica: diversity and interactions in late Palaeozoic and Mesozoic polar forest ecosystems
Abstract Chert and silicified wood from the Permian through Cretaceous of Antarctica contain abundant information on fungal diversity and plant–fungal interactions. The chert deposits represent aExpand
