Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Early Devonian graptolites from Tasmania [PDF]
Papers and Proceedings of The Royal Society of Tasmania, 1989 Monograptus thomasi Jaeger occurs in siltstone just east of Flowery Gully in northern Tasmania and indicates an early Devonian age for the host rocks.

Paleomagnetism of the Silurian-Devonian Andreas redbeds: Evidence for an Early Devonian supercontinent? [PDF]
Geology, 1988 Two components of magnetization were isolated in the Silurian-Devonian Andreas redbeds of the central Appalachians of Pennsylvania (lat 40.75 degrees N, long 75.78 degrees W): a thermally distributed, synfolding B component, and a thermally discrete, pre-Alleghenian-age folding C component.

Structural details of Early Devonian dipnoans
Australian Journal of Zoology, 2014 The evolution of the Dipnoi is displayed in the Early Devonian in south-eastern Australia. The main points at issue are as follows. (a) The development of the tubercles in the two-layered rostral region of the skull. (b) The nerves ophthalmicus profundus V and opthalmicus superficialis VII, and their sensory function.

Trauma in the life of a Nebuloxyla, an Early Devonian basal euphyllophyte [PDF]
Acta PalaeobotanicaAnatomically preserved material from Lower Devonian strata of the Battery Point Formation (Gaspé Peninsula, Quebec, Canada) offers a rare opportunity to reconstruct the sequence of events in the life of a Nebuloxyla mikmaqiana plant (early euphyllophyte) that led to wounding and the plant’s recovery after wounding.

The Early Devonian (Emsian) acrotretid microbrachiopod Opsiconidion minor Popov, 1981, from the Alaska/Yukon Territory border and Novaya Zemlya [PDF]
Estonian Journal of Earth Sciences, 2020 New records of the poorly known acrotretid (Biernatidae) microbrachiopod Opsiconidion minor Popov are described from middle Emsian strata of the Ogilvie Formation in east-central Alaska and the adjacent Yukon Territory, Canada, and compared with new ...

Oldest coelacanth, from the Early Devonian of Australia [PDF]
Biology Letters, 2006 Coelacanths are well-known sarcopterygian (lobe-finned) fishes, which together with lungfishes are the closest extant relatives of land vertebrates (tetrapods). Coelacanths have both living representatives and a rich fossil record, but lack fossils older than the late Middle Devonian (385–390 Myr ago), conflicting with current phylogenies implying ...

Royal Society Open Science, 2021 Evidence for terrestriality in early tetrapods is fundamentally contradictory. Fossil trackways attributed to early terrestrial tetrapods long predate the first body fossils from the Late Devonian.

Keraphyton gen. nov., a new Late Devonian fern-like plant from Australia [PDF]
PeerJ, 2020 The first plants related to the ferns are represented by several extinct groups that emerged during the Devonian. Among them, the iridopterids are closely allied to the sphenopsids, a group represented today by the genus Equisetum.
