El Monstrocrinus incognitus fue un crinoideo del Dev贸nico inferior y medio (395-397 MdA) con espinas insertadas en las placas c贸ncavas del c谩lix en la base de su teca, es decir, el segmento desde donde se ramifica. Pudieron ser una defensa, una estrategia hidrodin谩mica para dirigir las corrientes a su boca o estabilizadores frente a las corrientes de agua. 馃摲Bohat媒, 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"

Los trilobites del g茅nero Comura son naturalmente espinosos. Tanto, que tienen espinas sobre los ojos. 馃摲sulla55 #Devonico #Devonian #trilobite
