Paleoenvironments of Late Devonian tetrapods in China [PDF]

Scientific Reports, 2023
The major evolutionary transition from fish to amphibian included Late Devonian tetrapods that were neither fish nor amphibian. They had thick necks and small limbs with many digits on elongate flexuous bodies more suitable for water than land.

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.

The role of sea-level change and marine anoxia in the Frasnian–Famennian (Late Devonian) mass extinction [PDF]

Palaeogeography, Palaeoclimatology, Palaeoecology, 2008
Johnson et al. (Johnson, J.G., Klapper, G., Sandberg, C.A., 1985. Devonian eustatic fluctuations in Euramerica. Geological Society of America Bulletin 96, 567–587) proposed one of the first explicit links between marine anoxia, transgression and mass ...

Early sarcopterygian morphological disparity through the Devonian-Carboniferous crisis [PDF]

Scientific Reports
Major morphological adaptations characterized the early evolutionary history of sarcopterygians during the Devonian (419–359 Ma) and the Carboniferous (359–299 Ma), punctuated by environmental changes and biodiversity crises.

High-Resolution Late Devonian Magnetostratigraphy From the Canning Basin, Western Australia: A Re-Evaluation

Frontiers in Earth Science, 2021
Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.
