Probably can go in here...
Chinese paddlefish, one of world's largest fish, declared extinct
Native to China’s Yangtze River, these fish grew 23 feet in length, but haven’t been spotted since 2003.

@taniwharugby didn't see that on river monsters! Stink.

That’s sad . Those huge freshwater stingrays will probably be next

This is bloody interesting...

I always struggle to comprehend this, makes my head hurt
We analysed the amounts of lead and uranium isotopes in these crystals using mass spectrometry, and found their clocks had been reset 2.229 billion years ago (give or take five million years). That’s when we realised Yarrabubba coincided with a major change in Earth’s climate.

@taniwharugby haha yea, timescales like that are too hard for my brain to comprehend
Like that ones about one type of dinosaur being closer in time to us than another type of dinosaur.

Yeah dinosaurs existed from 240m years ago to 60m years ago.
So front end dinos existed 180m before the last ones, only 60m years ago.
Only a tiny fraction of the 4.5 billion years earth has existed, or 3.5b years of life.
On a similar note the mammoths and pyramids one gets me.

What the Mammoths/Pyramids one?

one i read the other day was that the founding of Cambridge University predates the Aztec empire. Which, while not of the same mind-bending time scale, still surprised me

Melting permafrost has made it easier to harvest their ivory
The climate crisis has sparked a Siberian mammoth tusk gold rush
The Arctic permafrost is thawing, revealing millions of buried mammoth skeletons. But the rush for mammoth ivory could put elephants in danger all over again

The last widow of a US civil war veteran died in 2008 , surprised me to find that out .

Yeah I still struggle to understand how they can say this happened so many billion years back, when, well, billions of years...yeah yeah, science, but still...guess its easier whan you have such a big window 2.229 billion years, margin of error of 5 million...pfft.
@booboo also time, in terms of light years, some more staggering numbers
A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers).

It's likely to be a somewhat more accurate estimate of Earth's age than Bishop Ussher's

Yeah that always makes me feel really small.
The fact the that farthest star is reachable (if still around) if we travel at the speed of light for 9,000,000,000 years.
Even if we could travel at speed of light, the fact that we could do so for a year and not be very far into the universe is staggering.

Not so smart are we. Man can't travel at the speed of light and we really would need to go faster to get anywhere, yet we can't look after the island that we live on.
Yeah that always makes me feel really small.
Our tiny little lives are but a grain of sand on the beach of the cosmos.

Oh, I don't know. I once put on a pair of lined running shorts that had a wasp in them. I think I got those off quicker than that....
