Plate Tectonics. During the Early Devonian, the microcontinent of Avalonia collided with the northeastern part of the Laurentia (by now part of the Euramerican continent). New jawless fish found from the Lower Devonian of Yunnan, China by Chinese Academy of Sciences Fig.1 Photograph of a complete head-shield of Rhegmaspis xiphoidea (IVPP V A, holotype).
The massive southern hemisphere glaciers that had formed during the Late Ordovician began melting, and Earth’s climate became relatively stable. By the end of the Silurian, the collision between eastern Laurentia and western Baltica closed the northern part of the Iapetus Ocean and resulted in the formation of a huge mountain range. Land fauna included spider-like and millipede-like predators, in addition to herbivorous (live plant) and/or detritus feeders. During the Silurian period Earth's continents joined together, closing the Iapetus Ocean and forming two supercontinents: Laurasia in the .

Late Hirnantian and early Rhuddanian shelly faunas dominated by brachiopods are well developed in the clastic facies succeeding the cool and deep-water, very-low-diversity Hirnantia fauna in Zhejiang and Jiangxi provinces, south-east China; elsewhere in the world, during this interval, brachiopod assemblages are generally rare.

L Dineley. The oldest fossils of land plants visible with the naked eye are about million years old. They are miniscule plants from the Mid-Silurian of Ireland en are called Cooksonia. Cooksonia plants had dichotomously divided little stems with small knobs at the end.
These knobs were sporangia and they were filled with spores. During about 20 or 30 millions of years these were the most.

The Devonian (/ d ɪ ˈ v oʊ n. 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 Early Devonian graptolite fauna of the Arctic Islands comprises the highest species content (17 species) in the world.

The Devonian mass extinction occurred during the latter part of the Devonian at the Frasnian - Famennian boundary. The crisis primarily affected the marine community, having little impact on the terrestrial flora.
This same extinction pattern has been recognized in most mass extinctions throughout earth history.

The upper Silurian–Middle Devonian succession was dominated by carbonate and evaporite deposits, with minor siliciclastic sedimentation, and a significant hiatus across the Siluro-Devonian (S-D) boundary in southwestern Ontario. The stratigraphic units include, in ascending order: Late Silurian Bass Islands/Bertie formations and Salina G Unit, the Devonian Oriskany Formation, Author: Shuo Sun.
The Cambrian Period was followed, million years ago, by the Ordovician Period. At that time many species died out, to be replaced by new ones in another evolutionary “explosion”, called the Great Ordovician Biodiversification Event (or GOBE).
During the Ordovician, the seas surrounding North America and Europe became rich in life, especially trilobites, brachiopods and reef.

Throughout the early Paleozoic, the Earth's landmass.During the Devonian land plants evolved, and the microscopic spores they produced are sometimes found as fossils. Towards the top of the largely unfossiliferous Devonian succession in the Mendips, there are the remains of plants and fish, heralding the dramatic change in environment that occurred across the region at the beginning of the Carboniferous.
