f many species do not always correspond to their total ranges. Apparent extinctions in the North Sea area appear to coincide with the onset of unfavourable environmental conditions, usually in the form of shallowing.ABYSS 发表于 2025-3-23 15:00:48

Matthew R Fairholm,Gilbert W Fairholmasserines secondarily regained anisodactyl feet in their evolutionary history. Based on these new insights in the evolution of parrots and passerines, some fossil taxa, which were initially identified as stem group representatives of the Psittaciformes, are now considered to be zygodactyl stem group passerines.小母马 发表于 2025-3-24 08:32:05
Matthew R Fairholm,Gilbert W Fairholm top of Younger Dryas (M3c/M4) is dated to 10.610 v.y. BP when first distinct layers of planktonic diatoms occur. Therefore the Pleistocene/Holocene boundary is fixed lithologically by varve counting, beginning at the isochrone of LST (11.323+/-224 v.y. BP), to 10.610 v.y. BP.托运 发表于 2025-3-24 10:43:58

Matthew R Fairholm,Gilbert W Fairholmo recognized, other mechanisms, e.g. motions of micro-plates or exotic terranes, may also cause rock masses to rotate about verical axes. Therefore paleomagnetic data on rotation must be combined with structural data in order to identify the contribution of faulting to block rotation.Goblet-Cells 发表于 2025-3-24 19:47:24
