Devonian period timeline
Reptile - Evolution, Paleontology, Adaptation: The first land vertebrates, the Tetrapoda, appeared near the middle of the Devonian Period. The earliest known reptiles, Hylonomus and Paleothyris, date from the Late Carboniferous. The Mesozoic Era is known as the “Age of Reptiles.” Today's reptiles represent only a fraction of the reptile groups and species that have lived.Also continued into Devonian period as the Acadian Orogeny, above (thus Euramerica forms). Taconic Orogeny tapers off. Icehouse period ends late in this period after starting in Late Ordovician. Lachlan Orogeny on Australian continent tapers off. 423 ± 2.3 * Ludlow: Ludfordian: 425.6 ± 0.9 * Gorstian: 427.4 ± 0.5 * Wenlock: Homerian: 430.5 ...Listen to article. Famennian Stage, uppermost of the two standard worldwide divisions of Late Devonian rocks and time. Famennian time spans the interval between 372.2 million and 358.9 million years ago. The name of the Famennian Stage is derived from the region of Famenne in southern Belgium, which has served historically as the type district.

The Carboniferous Period (which began 359 million years ago) is known as the 'golden age of sharks'. An extinction event at the end of the Devonian killed off at least 75% of all species on Earth, including many lineages of fish that once swam the oceans. This allowed sharks to dominate, giving rise to a whole variety of shapes and forms. The Cambrian explosion was a sharp and sudden increase in the rate of evolution. About 538.8 million years ago, at the onset of the Cambrian Period, intense diversification resulted in more than 35 new animal phyla; however, new discoveries show that the “explosion” started roughly 575 million years ago, near the end of the Proterozoic Eon (2.5 billion to 538.8 million years ago), with the ...Fungus - Evolution, Phylogeny, Eukaryotes: Fungi have ancient origins, with evidence indicating they likely first appeared about one billion years ago, though the fossil record of fungi is scanty. Fungal hyphae evident within the tissues of the oldest plant fossils confirm that fungi are an extremely ancient group. Indeed, some of the oldest terrestrial plantlike fossils known, called ...Devonian. In the Devonian Period, Britain lay south of the equator and had a semi-arid climate.

After the extinction-lacking end of Silurian, we are back to the mass extinction event way to close the periods.
