    Notes: [Auszug] PALAEOBIOLOGY has, in its own jargon, undergone a recent evolutionary explosion. Twenty years ago the study of fossil plants consisted largely of investigating their structure, and where possible reconstructing the whole plant from its variously preserved fragments. In the past two decades, ...

    Notes: [Auszug] More than 1,000 specimens were collected from an exposure alongside the Unayzah to Buraydah road, in the town of Unayzah (Fig. 1). The plants are preserved as impressions in a 5-20-cm limonitic shale band within a sequence of beds of alternating sand and shale, close to the base of the Khuff ...

    Notes: [Auszug] Melville has also suggested2?4 that the fructifications of some Glossopteridae, as reconstructed by Plumstead, have features in which they resemble the "Gonophyll"? the basic morphological unit of Melville's new theory of angiosperm flower structure. The proposition of the derivation of angiosperm ...

    Notes: [Auszug] Knowledge of early seed plants has grown significantly in the past decade1-7, and has an important bearing on the interpretation of their early evolution. The most convincing record of a seed of Devonian age is that of Archaeosperma Pettitt and Beck5 from the North American Famennian. This seed, ...

    Notes: [Auszug] Natural fires have been documented in grassland, tundra, boreal forest, deciduous forest and tropical evergreen forest ecosystems in North America1,2. In the southeastern US, fires are common in drought-dried peat3. Burning may also occur in dried strand-line accumulations of both aquatic and ...

    Notes: [Auszug] The Gund Formation comprises about 500 m of cyclic sediments consisting of conglomerates, sandstones and shales. It overlies unconformably the Syringothyris Limestone, regarded as of Tournaisian age on faunal grounds, and is overlain by the Fenestella Shale Formation of Upper Visean to Bashkirian ...

    Notes: [Auszug] The widespread appearance of megaphyll leaves, with their branched veins and planate form, did not occur until the close of the Devonian period at about 360 Myr ago. This happened about 40 Myr after simple leafless vascular plants first colonized the land in the Late ...
