Just returned from two weeks of archaeological excavation on an uninhabited island in Brittany for @univbrest.bsky.social summer archaeological field school. Shell midden archaeology at its finest : bones, shells, shards and friends 💥 #PaleoSky 🏺 🦑
Absolutely, that discovery is the reason why I unearthed this old thread 😊 bsky.app/profile/jfcu...

The "trilobit pendant" paper : link.springer.com/article/10.1...
Wear marks on trilobite fossil found in archaeological context suggest that the Romans may have used it as ornament. Very cool find, and a good excuse to bring back this thread on antique palaeontology ! bsky.app/profile/jfcu... #PaleoSky 🏺 ⚒️ 🦑

Biologist folk (especially in evolutionary biology and/or ecology, but it don’t matter): Can you give me your favorite examples of trade offs in biology? Organism or system don’t matter. Primary literature or reviews preferred.

🌍 🧪 Some news from the sceptics «scientific» arguments : - There’s a warming, but caused by a volcano, not humans - Wait, there’s a warming, but it’s the sun, in a very predictable way - But the models fails to predict it - Wait, there is no warming, only fake data All this in just 3 days.

Soil erosion in the Alps rose 4 to 10× over the past 3,800 years due to agropastoralism (clearing, grazing, intensive farming), outpacing natural soil formation. Lake sediment analysis reveal how high-altitude herding since Bronze Age and ploughing in the Middle Ages intensified the degradation.

Just found out there’s a pitcher plant (Nepenthes sp.) in Borneo that survives solely on nitrogen from treeshrew (Tuapia montana) poop. To ensure a steady supply, it evolved a specialised platform and offer sweet sap so the mammal can defecate perfectly at ease.

The objects from the funerary banquet are still in place, many of them ceramics with Etruscan geometric patterns. A basin and decorative bronze elements are still in place on the funerary bed.
A few days ago, the closing slab of an untouched Etruscan tomb was removed by archaeologists in the necropolis of San Giuliano (Barbarano Romano, Lazio). The burial chamber is from the 7th century BC. Can you imagine the emotion entering this tomb, untouched for 2600 years ? #PaleoSky #TombTuesay🏺
I’m not saying that the world has gone woke, but back in my day we had pig of the sounder pics on Wikipedia.
A unique features of the late Iron Age Lattara site in southern France : the presence of shell decorations on the dirt floors. The best-preserved example depicts a galloping equine (donkey or horse), made from tellins (a small marine shell common along the Languedoc coast). #MolluscMonday

These tiny creature are called the "carriers of stone seeds" in Ancient Greek. Known as coccolithophores, these algae shield their bodies in stunning calcium plates. In ancient times they were so numerous their bodies—piled in the trillions—formed the rock of the White Cliffs of Dover, in England

Considering the absurd week-end we just had, let me present you an absurd creature with a no less absurd name for #MolluscMonday 🦑 The Anadon's babakine (Babakina anadoni), a sea slug living in the Atlantic. Quite uncommon but a really cool guy, simply grazing on hydrozoans, as we should all do 🌊 🌿

It’s the first time for me on this game, so I have quite a lot of mechanics to digest before getting into that part, but it looks promising !
I just launched the game on the new Switch 2 version, and look what I found ! #NoManSky #PaleoGaming ⚒️ 🦖

Smuggled anti-establishment music, abandonned medical material and postwar USSR, all the elements for a good story are gathered here !
That's also the broad conclusion of our works on Neolithic/Bronze Age middens in Brittany (see my pinned post). But a bronze casted limpet was also found in a ritual site in Ushant (Mez Notariou). Relationship with these animal were probably more complex than what we see from archaeological remains!
My humble contribution
More info about 🦴 music here : www.theguardian.com/music/2015/j...
In 1950s USSR, banned record were pressed on discarded medical radiography and were known as « roentgenizdat », or « bone music ». I wonder how « substantial » they felt back then !
I see a limpet I repost. Simple as that🏺 🦑

5/ Original description of the colony was published in @currentbiology.bsky.social and can be found here : www.cell.com/current-biol...
4/ This colony is so vast it shapes the entire local ecosystems, influencing local food webs, biogeochemical cycles and serving as a key feeding ground for Weddell Seals. This remarkable discovery should now advocate for the creation of a Marine Protected Area in this part of the Southern Ocean 🌊
3/ According to the authors of the original study, it's "the most spatially expansive continuous fish breeding colony discovered to date globally at any depth", thriving in relatively warmer local conditions (up to 2°C, not bad for the Antarctic !)
2/ An estimated area of 240 km2, for a total of ∼60 million active nests, each nest containing one adult and about 1 700 eggs. This represents a total fish biomass of >60,000 tons...
Just a few years before the discovery of the Mediterranean picarel colony, another massive "fish metropolis" was found, this time in the southern Weddell Sea (Antarctica). It was built by Neopagetopsis ionah, Jonah's icefish. And once again, the scale is absolutely crazy... 🧪 🌊 🦑 🌿

On May 29, 2025, atmospheric CO₂ concentration at the Mauna Loa Observatory reached 430.71 ppm. When I was born in 1991, the global average was around 355 ppm. A cataclysmic geological shift in just three decades, and no serious effort to « flatten the curve » here.
Lazy #MolluskMonday today : here is some cheap IA slop I found on Facebook. Might do better next week.
