"do not eat the forbidden gummy bear lollll"

Someone actually 3D-scanned the Neolithic amber bear, printed molds, and created edible cola-flavored gummy bears based on them.

Who's going to stop me from eating the forbidden gummy bear now ?? 🐻

Even rabbits can be ecosystem engineers if there are enough of them.

We need more beavers in our life.

You don't know it yet, but you *have* to watch this animation of beavers reshaping river ecosystems.

This is the kind of stuff that sent me into environmental science.

2/2 The interesting thing here is that these shells comes from a late Neolithic shell midden (2,200 BC), and their shape tells us about the different exploited shore zones. Smaller + flatter shells can even highlight overexploitation events, as people had to go farther down the shore.

Two limpet shells on a lab bench. They are about the same lenght but with different morphology. Left one is rather flat with smooth surface, while the right one is higher, with coarser surface and more pronounced ribs.

1/2 Two different limpet shells, belonging to the same species (P. vulgata).

The flat one comes from low shore (large foot + reduced shell surface to resist strong waves and currents) while the pointed one comes from high shore (ribs + high shell help resist dessication by creating shadowed area)

Anthropocene stray dogs

Black‑and‑white photo of a parked helicopter on a tarmac, its nose covered with a handwritten protest sign about pork prices, while a dead pig hangs upside down by a rope from one of the main rotor blades against a cloudy sky.

Agricultural policy or performance art ?

In 1978 in Finistère (my home 💙), President Giscard d’Estaing’s visit was disrupted by farmers who tagged his helicopter and hung a dead pig from its blade.
​
The impact on farmers’ lives remains unclear, but the protest left an iconic image.

My favorite winter activity : binge watch aquascaping videos

Knowing that the earliest form of art in human and pre-human history could be an Indonesian shell that some Homo erectus dude engraved with zigzags 500,000 years ago definitely satisfies the shell nerd in me.

Why does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...

A snowbank on both sides of a cleared sidewalk is shown in cross‑section, humorously annotated like an archaeological profile. On the left wall, three horizontal snow layers are labeled from bottom to top “early snowfall event,” “early snow plough deposit,” and “massive snowfall event,” with a line at the base marking “extent of excavation” down to the exposed pavement labeled “bedrock.” On the right wall, multiple undifferentiated snow layers are labeled simply “snow,” with a vertical gap through the bank identified as a “processional way (pizza delivery)” leading from the sidewalk to the street. Near the outer edge of the right bank another small feature is marked “faunal remains? (tauntaun?),” and the thin wet band along the pavement is labeled “slush layer.” Bare winter trees, parked cars, and buildings are visible in the background.

Not right now, but the work was conducted by Isabelle Rouget from the Paris Museum, if that helps

🪶 Just a few days after this post, a remarkable bird is causing a stir in a small village of my native Brittany: a Belted Kingfisher, coming from North America.

As a result, between 30 and 40 twitchers on site, , coming from all over the country, sometimes up to 150 ??

A 4 toed fossil footprint of an early amphibian

On the 4th day of fossils, my true love gave to me...

A 4 toed amphibian track!

Batrachichnus is from the Carboniferous Mansfield Formation of southern Indiana. This is the name of the trace fossil because it's unknown exactly what animal produced it. The print is ~2cm long.

‘Magical’ galaxy frogs disappear after reports of photographers destroying their habitats Researcher in Kerala rainforest sounds alarm after being told frogs had died after being handled by humans

I once thought wildlife photography could raise awareness of biodiversity loss.

Yet with the hobby's popularization and gear affordability, the race for clicks and likes has seemingly outweighed the conservation value.

And I say this as a practitioner myself.

A 75m long chambered cairn , 2300 years older than the Great Pyramids of Egypt, made of 11 different chambers.

As André Malraux called it, "a true prehistoric Parthenon".
