Anoxic events have a buildup to them, notably in the early days of land plants, with nutrient flow from land slowly rising as wet areas expand over ~800 kyr prior to the main event.

Si eres de los que tenías problemas en comer pescados con espinas, los peces placodermos artrodíros estaban en la misma situación con el trilobite Dicranurus monstrosus. Vivió en el Devónico inferior y tardío (413-393 MdA) y, además de sus largas espinas, se distinguía por sus dos cuernos retorcidos en la glabela. 📷Daderot #trilobite #devonico #devonian

El Monstrocrinus incognitus fue un crinoideo del Devónico inferior y medio (395-397 MdA) con espinas insertadas en las placas cóncavas del cálix en la base de su teca, es decir, el segmento desde donde se ramifica. Pudieron ser una defensa, una estrategia hidrodinámica para dirigir las corrientes a su boca o estabilizadores frente a las corrientes de agua. 📷Bohatý, J. et al, 2023 #devonico #devonian

Massive wildfires followed oceanic anoxic events during the Late Devonian Frasnian-Famennian mass extinction.
Wildfires are an integral component of Earth system. They play an important role in the development and maintenance of varied types of landscapes and biomes that are important for the sustenance of biodiversity.

Let's go back to the best fossils and really look and think about what we are seeing and what it could mean with this organism.

Scientists may have discovered a new extinct form of life https://phys.org/news/2026-01-scientists-extinct-life.html
Prototaxites fossils are structurally and chemically distinct from extinct and extant Fungi https://www.science.org/doi/10.1126/sciadv.aec6277
"#Prototaxites was the 1st giant organism on the terrestrial surface, represented by #fossils of up to 8m from the #Devonian... fossils of P. taiti were chemically distinct from contemporaneous #Fungi, structurally distinct from all known Fungi. This casts doubt upon its fungal affinity"

Quadrops flexuosa es un trilobite del Devónico medio con un rostrum en forma de tenedor, aunque algunos especímenes, que pueden ser de otra especie, lo tienen en forma de cuchara. 🏛️Museo Field de Historia Natural 📷James St. John #Devonico #Devonian #trilobite

Hay peces espada, pero no hay ninguna ley que impida la existencia de trilobites espada. El Psychopyge termierorum es un trilobite del Devónico temprano (410-393 MdA) con una glabela alargada y puntiaguda. Sus espinas genales y laterales no se quedan atrás. 🏛️Museo de Ciencia Naturald e Houston #trilobite #devonico #devonian

The rise of lichens during the colonization of terrestrial environments https://www.science.org/doi/10.1126/sciadv.adw7879
"#Lichens were already widespread more than 410 million years ago, according to a new study that identifies a fossil from #Brazil as one of the oldest lichen... lichens were not marginal organisms, but key pioneers in the transformation of Earth's surface"

Rising Deep-Ocean Oxygen Levels Opened Up New Marine Habitats, Spurred Speciation https://nicholas.duke.edu/news/rising-deep-ocean-oxygen-levels-opened-new-marine-habitats-spurred-speciation
Mid-#Devonian ocean oxygenation enabled the expansion of #animals into deeper-water habitats https://www.pnas.org/doi/10.1073/pnas.2501342122
"390 million years ago in the ancient #ocean, marine animals began colonizing depths previously uninhabited. New research indicates this underwater migration occurred in response to a permanent increase in #DeepSea oxygen, driven by the aboveground spread of woody #plants"

Fish tracks show earliest adaptations for moving on land https://phys.org/news/2025-08-fish-tracks-earliest.html
Traces of dipnoan fish document the earliest adaptations of vertebrates to move on land https://www.nature.com/articles/s41598-025-14541-8
"Lower #Devonian fossilized trackway found in #Poland, attributed to dipnoan #fish... the earliest record of fish testing the land mobility skills of vertebrates, predating by about 10 million years the first evidence of fully terrestrial tetrapod locomotion."

Big heart, acute senses key to explosive radiation of early fishes https://phys.org/news/2025-08-big-heart-acute-key-explosive.html
Novel assembly of a head–trunk interface in the sister group of jawed vertebrates https://www.nature.com/articles/s41586-025-09329-9
"The standard theory holds that jaws evolved first, and other body parts underwent changes to sustain a new predatory lifestyle... The new study flips this idea on its head... This #fossil from the #Devonian, > 400 million years ago, shows that acute senses, powerful heart evolved well before jaws"

Cycling on #Bute this Thursday and came across the Kingarth Standing Stones which had previously been hidden by forestry plantation. Two are made of the local #Devonian conglomerate, the third looks like a sandstone. One of the conglomerate stones is an amazing bulbous shape. Erected & then shaped? Who knows?

My 25 years of palaeoart chronology...
Some zooms into my "Denizens of the Beach and Copse" painting (2022), showing the Severn Estuary in the Late Devonian. Featured are a group of Elginerpeton, an Ichthyostega, fungi, slime moulds, algae, rhyniophytes, zosterophylls, lycopsids, & equisetids.

"Something much worse than asteroids" is hype: the late-#Devonian and end-#Ordovician were less severe that the end-#Cretaceous, which was definitely† caused by an #asteroid. But this is good work that may help nail down the cause of the earlier #extinctions ... which were still pretty bad!
†Yes.

Hace 365 millones de años, en el Devónico tardío, surgió el Acanthostega gunnari, intermedio entre los peces de aletas lobuladas y los tetrápodos, aunque este no abandonó el agua porque no podía sostener su peso fuera de ella. Vivía en pantanos con poca agua y llenos de hierbas. 📷SeismicShrimp #devonico #devonian
