World's oldest skin fossil found so far -- a sample from 286-289 million years ago, before the earliest dinosaurs by at least 40 million years but incredibly similar to modern crocodiles https://newatlas.com/biology/worlds-oldest-skin-reptile-dinosaur

Well, at least these probably didn't float around and land on you.

This Arachnid in Illinois Had Armored Spikes on Its 8 Legs - The new species is too strange to be assigned a category, by Olivia Young May 30, 2024

"...“This is the big question,” says Jason Dunlop, co-author of the study. “The new fossil resembles some (but not all) living harvestmen”—aka daddy longlegs—“with spiny legs, and has some vague similarities to mites,” although he says its body is much bigger. The segmentation pattern and slight constriction between the head area and abdomen suggest that it may belong in a group with whip spiders and whip scorpions, “but unfortunately we can’t see the mouthparts, which would help us to confirm this hypothesis.”

So, maybe giant biting mites, possibly poisonous (ala daddy longlegs). Sounds fun [not].

Spent some time hanging out with some blue #damselflies at the lake before coming back home 😊

Damselflies have existed since the Late #Jurassic period & found on every continent except Antarctica. Presence of damselflies & the larger dragonflies, indicates a healthy #ecosystem.

Several blue damselflies, perched on & flying around water lily leaves.

BIOLOGY. The geometry and make-up of surface layers on (prokaryotic) cells. Interesting to think of the natural geometric patterning of proteins as layered system boundaries that are necessary for life.

The Bartgeier, also known as the Bearded Vulture or Lammergeier, is found in the Alps and other mountain ranges of southern Europe. It has an incredible 3m/9.8ft wingspan or 1.4 LeBron James. Photo taken at Alpenzoo in Innsbruck, Austria. Alpenzoo continues to house and breed Bartgeiers as part of an ongoing conservation effort. #birds #science #ecology #biology #photography #nature #wildlife

Rare deep-sea squid filmed at depth

“The squid, which was about 75cm long, descended on our camera assuming it was prey, and tried to startle it with is huge bioluminescent headlights,” Associate Professor Stewart said.

please! Has anyone ever researched the evolutionary context of the fact that the hungry cheeping in a great tit nest outside the window triggers a feeding reflex in me? I suddenly want to breed aphids and catch midges. 🐥 🐦 🐛

A forest in Utah made of a single tree known as Pando has 47,000 stems and has amassed 6,000 metric tons of life in its thousands of years on Earth. It’s the largest living organism on the planet in terms of mass. Naturally, something that large and old has something to say, and recordings released this year let us “hear” it like never before.

Canada Mayflower (Maianthemum canadense), Pierce Road, #Harvard #Forest.

Wikipedia: "The plant is rich in calcium and phosphorus and as such makes up the bulk of the diet of white-tailed deer in the northeastern United States in the spring."

That's a lot of Canada Mayflower.
