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.
My 25 years of palaeoart chronology...
The third and final Severn Estuary painting (2022), this time showing the Late Devonian. "Denizens of the Beach and Copse" features a group of Elginerpeton, an Ichthyostega, fungi, slime moulds, algae, rhyniophytes, lycopsids, equisetids, & others.
"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.
Guess who found his red-cyan #3D glasses and some old photo experiments. (Photographed the feesh at the Cleveland Museum of Natural History, May 2011.)
Things that seem fragile can endure. Trilobites dominated the oceans for millions of years and not a single one still exists.
This is Devonian coral. From a coral reef 400 million years ago, now part of the rocky mountains in BC. A delicate thing whose descendants stood the test of time

#Coral photosymbiosis on Mid-#Devonian reefs https://www.nature.com/articles/s41586-024-08101-9
"The symbiotic relationship between #corals and their photosynthetic algal partners goes back at least to the Devonian (385 million years ago)"
The #InsertAnInvert2024 prompt lens eyes made me think of trilobites. Not only do they have the earliest complex eyes we know of with their compound eyes with separate clusters of photo receptors (or ommatidia) each with its own lens to make mosaic-like pictures in their brains, but their lenses were hard and made of the mineral calcite!

"The earliest-known plant seeds date back to the Late #Devonian epoch. This period marks a significant evolutionary milestone in plant history, as they transitioned from spore-based reproduction, as with ferns and mosses, to seed-based reproduction... However, little is known about wind dispersal in seeds during this time"
