Toward the end of the Devonian, some 70 percent of the invertebrates disappeared, with the greatest losses among marine and, to a lesser degree, among freshwater species; coral reefs disappeared entirely. Estimates of the duration of Late Devonian extinction range from , to 25 million :// The Late Devonian and Permian-Triassic intervals are among the most dynamic episodes of Earth history, marked by large secular changes in continental ecosystems, dramatic fluctuations in ocean oxygenation, major phases of biotic turnover, volcanism, bolide impact events, and rapid fluctuations in stable isotope systems and sea ://
The Late Devonian effusive rocks were likely much less voluminous than other Late Devonian traps (Kravchinsky, ; Bond and Wignall, ), although they were also widely distributed as submarine volcanism in the basement of the Barents Sea (Nikishin et al., ; Puchkov et al., ).

The Late Devonian - Early Carboniferous paleobiogeographic The Late Devonian is characterised by three episodes of extinction ("Late D") A major extinction occurred at the beginning of the last phase of the Devonian period, the Famennian faunal stage (the Frasnian-Famennian boundary), about Mya, when all the fossil agnathan fishes, save for the psammosteid heterostraci, suddenly disappeared.A second strong pulse closed the Devonian :// He has previously authored The Late Devonian Mass Extinctions () and When the Invasion of Land Failed (), and seeing how frequently he references the latter, the book under review and the title deserve close reading together.
McGhee first sets the stage, primarily focusing on the Devonian, Carboniferous, and Permian :// This book examines the profound evolutionary consequences of the Late Devonian extinctions and the various theories proposed to explain their occurrence.
Only one group of four-limbed vertebrates exists on Earth, while other tetrapod-like fishes are "Based on two decades of research, The Late Devonian Mass Extinction reviews the many theories that have been presented to explain the global mass extinction that struck the earth over million years ago, considering in particular the possibility that the extinction was triggered by multiple impacts of extraterrestrial objects."--Publisher's :// 2 days ago Devonian extinctions, a series of several global extinction events primarily affecting the marine communities of the Devonian Period ( million to million years ago).
At present it is not possible to connect this series definitively with any single cause. It is probable that they may record a combination of several stresses—such as excessive sedimentation, rapid global warming or In the Late Devonian, large trees evolved and formed the first forests.
As plant life expanded, they used up more carbon dioxide in photosynthesis. When dead plant material decays, carbon dioxide is returned to the atmosphere, but some plant material (e.g., leaves) will be buried in swamps, lakes and rivers.
This buried plant material removes Late Devonian conodonts of northwest Thailand have been described previously by several workers, including Wongwanich and Burrett (), Burrett et al.

The basin center was probably located in the Berkine basin (Plate ). Internal offlaping sigmoidal stratal patterns are locally visible in the N–S seismic transect of PlateABSTRACT The standard Late Devonian conodont zonation is revised and expanded from 29 to 32 zones.
