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"

Trait-space disparity in fish communities spanning 380 million years from the Late #Devonian to present

The functional trait space of fish communities reflects evolutionary history, habitat, and climate.

Devonian and modern fish communities differ in their trait composition.

Trait differences imply ancient communities functioned differently.

Habitat- and climate-related patterns in functional diversity metrics are consistent across time.

Fossilium catalogus. Animalia / Pars 138, Ammoneae devonicae by Dieter Korn & Christian Klug

In the new Fossilium Catalogus presented here, numerous illustrations were included in the text in order to meet the various needs of a larger public with a diverse background. They are intended to clarify morphological and phylogenetic relationships, to facilitate identification of genera, as well as to make the volume less monotonous.

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."

Pterichthyodes milleri fue un pez antiarco del Devónico medio. Tenía la mitad anterior del cuerpo cubierta de placas. Sus ojos dorsales y su vientre plano sugieren que vivía en el fondo de los lagos, arrastrándose con sus apéndices pectorales. 📷Dmitry Bogdanov #devonico #devonian

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"

Sollasina cthulhu del Silúrico-Devónico (430-388 MdA) fue un ofiocistoideo, unos equinodermos una anatomía similar a los erizos de mar, salvo por el ano lateral los 45 pedicelarios cubiertos de estereomas. 📷Qohelet12 #Silurico #Silurian #Devonico #Devonian

Jaekelopterus rhenaniae fue un escorpión marino (Eurypterida) del Devónico temprano (401-402 MdA) y el mayor artrópodo conocido con una longitud de 2,33-2,59 m, sin contar sus quelíceros que medían otro metro.📷ДиБгд #devonico #devonian
