The Devonian (/ d ɪ ˈ v oʊ. n i. ən, d ə- d ɛ-/ dih-VOH-nee-ən, də- deh-) is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya.
It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation. The GSSP for the base of the Devonian and of the Lochkovian Stage is a point in Devonian change book rock record that was selected to also coincide with the FAD of the graptolite Monograptus uniformis uniformis (Fig.
).Recognition of the boundary in carbonate strata or in sections that lack graptolites is enabled by a major turnover in conodont species and a major positive carbon-isotope excursion at the.
Climate change finally led from greenhouse to icehouse conditions towards the end of the Devonian. Rapid evolution of terrestrial ecosystems and climate Devonian change book had a pronounced influence on sedimentation and biodiversity, not only in the terrestrial, but also in the marine realm.

This volume contains case studies from Australia, China, Europe, South America and North America, and individial palaeoecosystems and their components have been investigated in different palaeogeographic settings that contribute to a much better understanding of the Devonian period.
The focus of the present issue is on the complex interaction between climate change, sea-level fluctuations, and bioevents in the Middle Devonian, which were major themes of IGCP Devonian Period, in geologic time, an interval of the Paleozoic Era that follows the Silurian Period and precedes the Carboniferous Period, spanning between about million and million years Devonian Period is sometimes called the “Age of Fishes” because of the diverse, abundant, and, in some cases, bizarre types of these creatures that swam Devonian seas.
The Devonian was a period of great changes in climate and biodiversity with widely known black shale events linked with hypoxia/anoxia, eustatic fluctuations, faunal blooms, geochemical anomalies. McGhee is able to organize a vast literature into a coherent evolutionary story that is quite unique.
From the origin of plants and animals through the Devonian era, this book is a marvelous read. It is important for a wide variety of geologists and biologists and for any readers interested in paleontology and environmental s: The Middle and Late Devonian were times of unprecedented change in the appearance of land surfaces across the planet.
It saw the expansion of size (both height and average axis diameter), taxonomic and morphological diversity, habitats, and area of ground cover occupied by land plants. G.R. McGhee, in Encyclopedia of Geology, Introduction.
The Devonian Period of the Palaeozoic Era was only slightly shorter than the entire Cenozoic Era (63 million years as opposed to 65) and was a time of many ‘firsts’ in Earth history.
The Devonian saw the explosive diversification of vertebrate life (e.g., new fish species that proliferated in both marine and freshwater.
The Devonian Period was so-named in by geologists Adam Sedgwick and Roderick Murchison, after the county of Devon, England, where the rocks of this period were first studied. The Devonian, from – million years ago, witnessed major changes in plant life and fish, including some fish that ventured on land.
The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics.
Devonian Period - Devonian Period - Plants: It is now known that some supposedly Silurian plants, such as those at Baragwanath, Vic., Australia, are actually from the Early Devonian. The Late Silurian record of Cooksonia fossils of the Czech Republic seems to be the earliest unquestionable evidence of vascular plants.
Information on spores provided by palynologists would help determine the. The Devonian ancestors of fishes living today belonged to two main nonarmored groups. The cartilaginous fish, so-called because cartilage formed their skeletons, later gave rise to sharks and rays.
