Absolutely, that discovery is the reason why I unearthed this old thread 😊

French post stamp : a sauropod drawing with the mention "découvertes archéologiques nationales" (national archaeological discoveries) Due to the backlash, the stamp was finally not produced.

I'm sure you'll love this French Post Office's latest tribute to discipline...

What an amateur

True ! Any thoughts @amayor.bsky.social ?

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 !

An 850,000-year-old toddler’s neck bone from Spain shows clear signs of butchery, probably cannibalism.

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.

"Look what they took from us"

Screenshot from John Shewchuck : « Note that the UN controlled WMO makes no mention of the powerful Hunga Tonga volcano and its associated 2023/24 global heating spike, which was induced by water-vapor injection and not CO2. »

« To those new meteorology students following me ... there is evidence we are still thawing out from the Little Ice Age, but there is no evidence global warming and increasing CO2 harm our climate. »

« Why does the IPCC make climate models that consistently error on the hot side? Shouldn't there be a law against climate model fraud? »

« They want illegally obtained votes just as much as illegally tampered temperature data. »

🌍 🧪 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.

Human and climate impacts on the alpine Critical Zone over the past 10,000 y | PNAS Agropastoral activities have impacted the habitable part of our planet—the “Critical Zone”—for thousands of years, triggering a major increase in s...

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.

Intact 7th century Etruscan tomb discovered in San Giuliano necropolis near Rome Intact Etruscan tomb found in San Giuliano Necropolis sheds new light on ancient burial rituals and social customs in central Italy.

More info here :

archaeologymag.com/2025/06/inta...

External view of the tomb, with the closing slab still in place.

The funerary bed. Remains of the body are still visible.

Etruscan ceramic filling the tomb

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 ?
