This timeline of Carboniferous research is a chronological listing of events in the history of geology and paleontology focused on the study of earth during the span of time lasting from 358.9 to 298.9 million years ago and the legacies of this period in the rock and fossil records.
The Carboniferous (/ ˌ k ɑːr b ə ˈ n ɪ f ər ə s / KAR-bə-NIF-ər-əs) [6] is a geologic period and system of the Paleozoic era that spans 60 million years, from the end of the Devonian Period 358.86 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma.
Carboniferous graphical timeline −360 — ... Subdivision of the Carboniferous according to the ICS, as of 2023. [1] Vertical axis scale: Millions of years ago.
The Carboniferous extends from about 358.9 ± 0.4 to about 298.9 ± 0.15 Ma. [10] A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was ...
The Pennsylvanian (/ ˌ p ɛ n s əl ˈ v eɪ n i. ən / pen-səl-VAYN-i-ən, [4] also known as Upper Carboniferous or Late Carboniferous) is, on the ICS geologic timescale, the younger of two subperiods of the Carboniferous Period (or the upper of two subsystems of the Carboniferous System).
The Carboniferous period, the geologic time between 358.9 and 298.9 million years ago, during the Paleozoic Era See also the preceding Category:Devonian and the succeeding Category:Permian Subcategories
The Mississippian (/ ˌ m ɪ s ɪ ˈ s ɪ p i. ə n / MISS-iss-IP-ee-ən), [5] also known as Lower Carboniferous or Early Carboniferous, is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2
c. 358.86 ± 0.14 Ma – Beginning of the Carboniferous and the end of Devonian Period. Amphibians diversify. c. 345 Ma – Agaricocrinus americanus a representative of the Crinoids appears as part of a successful radiation of the echinoderms. c. 330 Ma – First amniotes evolve. c. 320 Ma – First sauropsids evolve.
