“…Similar estimates have been made for both land plants and vertebrates (e.g., Retallack, 1995;Visscher et al, 1996;Looy et al, 1999;Rubidge and Sidor, 2001;Rees et al, 2002), and recent proposals suggest that the decimation in the oceans was accompanied by a synchronous collapse in the terrestrial realm (Twitchett et al, 2001). There is some agreement that woody plants experienced a decline regionally (Retallack, 1995;Visscher et al, 1996;Looy et al, 1999;Kerp, 2000;Rees, 2002), which would have had direct effects on erosional rates, changes in atmospheric CO2 levels, carbon cycling, and ecosystem structure (MacLeod et al, 2000;Ward et al, 2000).…”

“…Global geographic patterns of Permian climates were reconstructed by Rees et al (2002), showing a significant latitudinal climate gradient, similar to the modern interglacial situation. Paleobotanical data (Ziegler, 1990;Cúneo, 1996;Ziegler et al, 2003) based mainly in compression-impression fossils of leaves, reproductive structures and seeds have shown that the provinciality of Gondwana changed significantly during the course of the Permian, mainly influenced by paleogeographic and paleoclimatic parameters (Rees et al, 2002). Potential macroplant associations are mainly the several taxa of the Glossopteris Flora, represented by woody and non-woody plants.…”

“…Glossopterids have been interpreted to represent tree-sized plants predominantly occupying mire and moist floodplain settings as their roots (Vertebraria) contain schizogenous cavities that were adaptations for aeration of tissues in dysaerobic waterlogged settings analogous to the roots of extant Taxodium distichum. Late Permian climates of southeast Gondwana have generally been interpreted as cool and moist (Table 1; Ziegler, 1990;Rees et al, 2002). This is supported by the dominance of glossopterids with broad, amphistomatic leaves, thin cuticle and relatively unsophisticated stomatal protection (Fig.…”

High-resolution palynofloral signatures through the Cretaceous-Palaeogene boundary succession show several features in common with the Permian-Triassic transition but there are also important differences. Southern Hemisphere CretaceousPalaeogene successions, to date studied at high resolution only in New Zealand, reveal a diverse palynoflora abruptly replaced by fungi-dominated assemblages that are in turn succeeded by low diversity suites dominated by fern spores, then gymnosperm-and angiosperm-dominated palynofloras of equivalent diversity to those of the Late Cretaceous. This palynofloral signature is interpreted to represent instantaneous (days to months) destruction of diverse forest communities associated with the Chicxulub impact event. The pattern of palynofloral change suggests wholesale collapse of vascular plant communities and short-term proliferation of saprotrophs followed by relatively rapid successional recovery of pteridophyte and seed-plant communities. The Permian-Triassic transition records global devastation of gymnosperm-dominated forests in a short zone synchronous with one or more peaks of the fungal/algal palynomorph Reduviasporonites. This zone is typically succeeded by assemblages rich in lycophyte spores and/or acritarchs. Higher in the succession, these assemblages give way to diverse palynofloras dominated by new groups of gymnosperms. Although different plant families were involved in the mass-extinctions, the general pattern of extinction and recovery is consistent between both events. The major difference is the longer duration for each phase of the Triassic recovery vegetation compared to that of the Paleocene. The protracted extinction-recovery succession at the Permian-Triassic boundary is incompatible with an instantaneous causal mechanism such as an impact of a celestial body but is consistent with hypotheses invoking extended environmental perturbations through flood-basalt volcanism and release of methane from continental shelf sediments.
