A wonderfully weird creature you'll find deep in the endangered Chocó Rainforest of Ecuador. It's a moss-mimic walking stick insect (Trychopeplus laciniatus). #insect #camouflage #rainforest

More Seismology 🤝 Hydrology Wallace Creek (dry in these photos) has been offset by the San Andreas fault. The two ~90° turns occur where it crosses the fault. The land on the left has moved over time ~north (direction of view) relative to the land on the right. Carrizo Plain National Monument.

"...the best learning happens where there is friction, or when a student needs to grapple with a problem and work through it." "When you use offloading tools... as a novice, as a student, you don’t learn the skill. You simply learn dependency." fortune.com/2026/03/01/a...

Timeline cleanse, first Trout Lilly of the season - thousands of these speckled leaves around the forest floor, just this bloom😍 #Nature #Flowers #Timelinecleanse

Here’s an interesting thing… greater dogtooth lichen, or Peltigera membranacea. It is remarkably big and fast growing for a lichen… you can see it overshadowing the moss underneath it here. I had mistaken it for a liverwort, but you can see lichen-like fruiting bodies in photo 2. #lichensubscribe

This is what they have in the USA and what Nigel Farage wants to bring to the UK.

Happy 6th "Large boulder the size of a small boulder" anniversary to those who celebrate! #Geology ⚒️

it’s all i’ve got

#FossilFriday Stack of opalised vertebrae from an Early Cretaceous ichthyosaur. Another remarkable fossil on display in the South Australia Museum, Adelaide.

A supposed dormant volcano erupts in Ethiopia after being inactive for at least 12.000 years. www.scientificamerican.com/article/hayl...

For #FossilFriday & in honor of @alinemghilardi.bsky.social & colleagues' fantastic discovery of a new Cretaceous pterosaur in Brazil in a dinosaur regurgitalite ("fossil vomit"), here's a diagram I made for my book 'Dinosaurs Without Bones' (2014) showing the physics of a puking brachiosaur. 🧪🦕🤮🪨

Here’s an actual metal version of Grieg’s In the Hall of the Mountain King, which I think the original is pretty metal anyway. Source: YouTube share.google/NkLz28HcYhXJ...

Tough choice: #carpathite bc I'm an organic chemist #tugtupite bc of tenebrescence (when a mineral changes color after exposure to UV light) Tugtupite from Greenland, left: after exposure to SW-UV; right: the pink color faded after ca. 1 day in its box. (this sample has been stolen 2023 😭)

The red tetrahedrons of Iranian #Zuniyite with the hematite inclusions won me over. Abundant crystals look like stars in the galaxy when they fluoresce.

As an organic chemist, I can only choose #Carpathite. Pls vote for the aromatic mineral!

Here is a nice mushroom

The pole shouldn't really affect the continent. There have been plenty of other times when a different continent (or no continent) has end up at the South Pole. See this reconstruction for the last 1.5 billion years by Scotese for example (latitude is much better constrained than longitude):

So…about AI’s energy use… “…to create a five-second video, a newer AI model uses ‘about 3.4 million joules, more than 700 times the energy required to generate a high-quality image’. That's the equivalent of running a microwave for over an hour.”

Made a cocktail for my wife and she put it in the freezer, inadvertently creating a new superorganism please hel—*glurk*

Another one from further back. Bearded iris, watercolour on VCPO handmade watercolour paper, approximately 87 × 150 mm, 2019. Again, the scan has considerably homogenised the blues and lost the subtle variations.

Happy Giant Phallus Shaped Iceberg Floating In Conception Bay of Dildo, Canada Day to all who celebrate.

Mossy leaf-tailed gecko, Uroplatus sikorae, Madagascar. These lizards have some of the most amazing camouflage in nature. I especially love the fractal fringing on the bottom jaw, feet, and body, which helps break up the lizard's outline. 🦎🌿 #herps

Warning sign about geologists ⚒️ Warning! If our favorite rocks fall off a cliff, we will chase after them.

Fresh impact crater on Earth! This impact occurred on 25 July 2024 in Prince Edward Island, Canada, when a small ordinary chondrite meteorite impacted Earth (someone's driveway, specifically) at about 200 km/h. The impact formed a set of crater rays.

Some branches of green algae Spirogyra, collected on a beach by Bothnian bay near Umeå. They have then been cultivated at home and observed at microscope x400, around july. Some branches then initiated conjugation (left pic); right pic: zygotes after conjugation.

Some red algae Ceramium from Bottenviken, Sweden, seen microscope. Found on beach near Umeå.

Seriously, y'all: what merits do you find in rhodochrosite?? How can you prefere a *pretty pink nothing else* to a splendid daughter of ultramafic and more (lizardite), a cool heavy metal (arsenuranospathite) and a promising material for clean energy (perovskite)?? C'mon folk, vote perovskite!

It's a catalyst! It's photoactive! It's freaking cool looking! #teamperovskite #mincup23

I absolutely appreciate corundum but lawsonite gets my vote bc: 1) blueschist facies are awesome 2) Sorosilicates deserve to get much more love (I'm still mad about my prof at basic geology class at uni, skipping sorosilicates alltogheter with "not so important")

Cinnabar has a slight lead over quartz and I'm not happy! Here's a *long* thread for #TeamQuartz which I'll be updating throughout the day #MinCup23 #geology ⚒🧪 1/? Vote for QUARTZ here: www.mineralcup.org/2023/campaig...

Cinnabar 🟥 vs quartz 💎 🟥uncommon, toxic, decorative, crystals ok, just 2 chemical elements, only red. 💎very common, safe, piezoelectric, makes rocks (quartzite) and glass, AND LOOK AT ALL THOSE COLORS AND CRYSTAL HABITS AND STUNNING GEOMETRIES WITH JUST 2 CHEMICAL ELEMENTS!!

I guess I should have tagged this thread for the birds feed. 🪶
