@hugo@social.treehouse.systems The one that continues to amaze me is that the Great Lakes are only 10k-14k years old, which is miniscule on geologic scales. Recommend reading about the last glacial maximum, the Holocene glacial retreat, the little Ice Age.

@hugo@social.treehouse.systems Wait, sharks are older than trees? That is seriously cool.

@hugo@social.treehouse.systems Sharks being older than trees always blows my mind. What did the first shark to see a downed log floating in the water do? Try to bite it, and get very confused?

@hugo@social.treehouse.systems Seen several sharks. Smallest was a pale Yellow 3’ Sand shark in a tide pool. Picked it up and carried to the water. Normal were 5-6’ Blue sharks also in sight of NYC. Largest was a 65’+ Black Nurse shark about 6-700 miles East of Miami, on a New York to Virgin Gorda passage. Chance, under sail in light winds within 100 yards before it submerged. It was almost as the big as the ship.

@hugo@social.treehouse.systems Sharks are just some of those ancient inhabitants of our misnamed planet: "Water." Brings to mind "The Magic of Reality" by Dawkins. It has a nice part where he shows a hugely long list of photos starting with our own, then our father or mother, one of our grandparents, and so forth for one of our ancestors in each of our previous generations. If we could go back far enough, as in a few million years, the photo would show us.. not even a mammal but a fish!

@hugo@social.treehouse.systems dragonflies are similarly old, around 300 million years. They don’t beat sharks, but they do beat most of your list too!

@hugo@social.treehouse.systems That's a neat comparison. Something related to think about: the shark lineage and the "all other vertebrates" lineage diverged 420 MYA. Why did one of those two lineages diversify morphologically so much more than the other? The two lineages are equal in age, but not equal in morphological diversity.

@hugo@social.treehouse.systems ‘sharks are older than the ocean’ would make a good bumper sticker.

@hugo@social.treehouse.systems @nyrath@spacey.space The age of Saturn's rings is argued about; as is how long they will persist. They could be as old as a few hundred million years. But probably still not as old as sharks.

@hugo@social.treehouse.systems Yes. But they were quite different to modern sharks.

@hugo@social.treehouse.systems And the Greenland Shark is estimated to live 250 to 500 years old. Fascinating animals.

@hugo@social.treehouse.systems Seems like Lovecraft should’ve chosen a shark template for his Great Old One Cthulhu, given that sharks predate octopuses.

@hugo@social.treehouse.systems I just learnt today that they're older than trees because I was visiting relatives and their children were watching a TV Contest in which they asked which were older. Nobody, not the contestants and not us, but my partner got it right. I'm still kind of astonished.

@suihkulokki@society.oftrolls.com 2023-11-26 17:14
@hugo@social.treehouse.systems Sharks are also older than Land animals (428 myo). Geologically that is right after sharks appeared, so I shall jump to the conclusion that it's not co-incidental - sharks appeared and some animals decided it's time to start evolving lungs ;-)

@hugo@social.treehouse.systems https://oceanservice.noaa.gov/facts/greenland-shark.html This blows my mind too. Imagining some sharks still swimming around who were out there circa the King James Bible.

@hugo@social.treehouse.systems I don’t think there’s quite consensus on this one yet, but the current leading theory about the age of the inner solid iron core of the earth says it’s about 500 million years old. So just “a bit” older than sharks, apparently.

@hugo@social.treehouse.systems Sharks predate trees? Wow. What did they eat before surfboards?
-
@dlaroe@fosstodon.org 2023-11-26 20:26
@hugo@social.treehouse.systems Trees are older than flowers and even older than wood rot. Now you mention sharks are older than trees. Isn't wood from trees that got buried before wood rot what became fossil fuels? Maybe since sharks are way older than fossil fuels they are a better mascot for the Green movement than trees and flowers.

@hugo@social.treehouse.systems Wow. At that age you’d think they’d have more wrinkles. Guess the ocean is really moisturising.
