The Kotlin Crisis: Earth’s first mass extinction may have been far worse than previously believed

Fossils of the first sea creatures, long assumed to have vanished before a major mass extinction about 550 million years ago called the Kotlin Crisis, have now been found and are providing new details about that time period.

This discovery transforms what once looked like a routine species decline in Earth’s early history into what may be the first catastrophic extinction in animal history.


Second, actually, after the Great Farting Oxygen Event changed the atmosphere from reducing to oxydizing -- almost everything died, except a few archaea that found anoxic refuges and a few organisms that figured out how to use oxygen. But most people forget about that one.

There will be a Bonus Fishbowl on Tuesday, March 17 with a theme of "anything goes." Think back over your favorite ideas that haven't fit a prompt call yet; you can suggest whatever you want in this one.




marchmetamatterschallenge is running this month. See my tracking post and the first check-in post.


The weather has been erratic here. We've had warm days. Yesterday was cold with howling wind, then pouring rain; today it snowed a bit and is still howling wind. Seen at the birdfeeders this week: a mixed flock of sparrows and house finches, a mourning dove, and a fox squirrel. Red-winged blackbirds have been singing overhead. Currently blooming: crocuses, snowdrops, winter aconite, miniature irises, daffodils, squill.

Today my partner Doug asked me to remove a bunch of staples for him.  I first looked for my staple remover but couldn't find it.  Instead I grabbed the tiny screwdriver that I got from Power Plus at the Home and Garden Expo.  It actually worked better.  Because it's swag, the screwdriver tip is very thin and narrow.  That made it a lot easier to slide under the ends of the staples to open them, then slide under the wide part of the wire to twist it loose.  Staple removers typically have very thick teeth that can be difficult to get under the wire.  So this is now my staple remover of choice, and will live in my office drawer.  :D

What most people call luck or opportunity is, in my observation, largely situational awareness.  I needed a tool; I thought about what would work; I used what I had.  And then I noticed that it worked better than a dedicated tool from the past.  A small discovery, but it makes my primate brain very happy. 

Today is cloudy and cool with howling wind. It's up to 18mph. A beautiful day to stay indoors and write!

I fed the birds. Unsurprisingly, I haven't seen any. I expect they're all huddled in whatever shelter they can find.

I put out water for the birds.

EDIT 3/15/26 -- I did a bit of work around the patio.

I've seen a small mixed flock of sparrows and house finches.

EDIT 3/15/26 -- I did more work around the patio.

A tiny scilla is blooming white in the purple-and-white garden.

It's starting to rain.

I am done for the night.

Today we went to Middlefork at the Mall in Lincoln Square Mall in Urbana. This is a big flea market, although not quite as big as the last one we caught. We both found some great stuff.

Scared of spiders? Scientists say the real nightmare is losing them

Scientists discovered that nearly 90% of North America’s insects and arachnids have no conservation status—revealing a huge blind spot in protecting the tiny creatures that keep ecosystems running.

Spiders and insects may not be fan favorites, but they are vital to the health of ecosystems—and scientists barely know how they’re doing. Researchers found that nearly 90% of North America’s insect and arachnid species have no conservation status, leaving their fate largely unknown. Even more striking, most states don’t protect a single arachnid species. The study warns that these overlooked creatures are essential to planetary health and urgently need better monitoring and protection.


Let me be blunt here: the insect (arthropod) apocalypse is going to pull the rug out from under the biosphere. Plants are the producers for most of the ecosystem; many essential plants rely on insects for pollination or other services. And the next layer is invertebrates, mostly arthropods -- they break down dead material to a size that fungi can deal with, they pollinate, they move seeds, they feed most of the next level up such as birds, amphibians, etc. Spiders in particular keep the rest of that arthropod mess in check so we're not buried alive in flies, mosquitoes, and so on. They're some of the tiniest predators and they're absolutely vital.

Today is cloudy and chilly.

I fed the birds.  I've seen a mixed flock of sparrows and house finches.

I put out water for the birds.

3/14/26 -- I did a bit of work around the patio.

I am done for the night.

 

Today we went to the Home and Garden Expo at the Otto Center. The parking lot was so full, we had to go all the way in the back to find a space -- there's a whole extra lot back there that we'd never even seen before.

Today is partly cloudy and chilly with blustery wind.

I fed the birds.  I've seen several sparrows and house finches plus a mourning dove.

I put out water for the birds.

3/13/26 -- I did a bit of work around the patio.

3/13/26 -- I moved the 16 water jug greenhouses from the parking lot to near the barrel garden.  Many of them have sprouts inside now!  :D

3/13/26 -- I trimmed brush along the north side of the house.

I am done for the night.
