This is only mind blowing because popular media likes to show every dinosaur at once. Like there’s a lot of things depicting stegosaurus fighting T-Rex; but these animals never would have met. They’re from entirely different periods.

Does getting buried in pumice count as becoming a fossil? Because Pompeii was only a couple thousand years ago.

SARGE@startrek.website on 18 Mar 02:33 collapse

From wikipedia: A fossil (from Classical Latin fossilis, lit. ‘obtained by digging’)[1] is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Answer: yes. It does count. Specifically carbonization.

Personal take: when I think of a “fossil”, I think of the stereotypical mineralized bones. Like the T-Rex in the museum of natural history that most people have seen from various movies and TV shows. Thinking of human and human predecessor bones as fossils is just weird to me.

Dave@lemmy.nz on 18 Mar 08:26 collapse

Is Pompeii from a past geological age?

2000 years ago doesn’t seem important on geological time scales.

SARGE@startrek.website on 18 Mar 11:33 collapse

Okay so even though I read all this last night, I somehow missed the “2000 - (-2000) years” thus making the current geological age around 4000 years, and technically Pompeii would not count in the strictest definition. That said, had it happened 4,000 years ago, absolutely nothing would have changed. All the stuff would still be carbonized.

Also from Wikipedia in the (geological age) article: An age is the smallest hierarchical geochronologic unit. It is equivalent to a chronostratigraphic stage.[14][13] There are 96 formal and five informal ages.[2] The current age is the Meghalayan.

So again the answer is “yes it counts” but my personal take is “it feels weird to consider 4,000-10,000 ago multiple different geologic ages”

Dave@lemmy.nz on 18 Mar 19:30 collapse

Reading through Geologic time scale, it defines an age as equivalent to a chronostratigraphic stage, which it says are normally millions of years. But you’re right, interestingly the current Meghalayan age only started 4,200 years ago.

It seems all the recent ages are only a few thousand years each (until 2018 the last 10,000 or so were one age, but this was split in three in 2018).

After all that reading I still didn’t really understand how they decided that this was a new age.

But anyway, I agree there isn’t going to be any difference between 2,000 and 4,000 years so we might as well consider Pompeii fossilised even if not strictly true under the definition. I’m just surprised we consider anything within human history to be a previous geological age, but it seems we do.

To be fair, things can fossilise very quickly given ideal conditions. Still dinosaurs reigned for a lot more time than mammals and frankly nature is still feeling the loss in certain ways.

Which makes me ask, why were mammals able to evolve to produce an apex predator that relies on it’s inventiveness (Humans) in quite a short time, but no similar “dinosaur” got to that point in a much longer period?

We’re searching planets for signs of life as a pre-cursor to intelligent life, but there’s no guarantee that life will evolve in the same direction as ours.

AngryCommieKender@lemmy.world on 18 Mar 16:02 next collapse

Corvids and psittacines display human child level intelligence. They use tools. They recognize other people. Hell the psittacines can mimic speech.

I personally suspect it’s a matter of energy density. Birds have to use almost all of their available calories on flying. Doesn’t leave a lot of energy left over for a massively hungry brain. No clue what’s holding back penguins, emus, and cassowaries.

exasperation@lemm.ee on 18 Mar 16:30 next collapse

Birds have to use almost all of their available calories on flying.

But flying is quite energy efficient as a method of getting from point A to point B. That’s why flying insects and birds have had such evolutionary success with that strategy.

AngryCommieKender@lemmy.world on 18 Mar 16:35 collapse

Is it though? They have to eat an absolute ton relative to their own mass. At least all the birds I’ve ever interacted with were constantly eating, even when they mostly didn’t bother flying. Chicken soccer is what I called feeding the chickens. No patience whatsoever.

My mother used to say that her sons eat like birds, a peck at a time, and twice our own body weight daily.

While we humans eat a lot, something like 50% of our calories are going to our brains. I’m not sure most birds could actually increase their caloric intake enough to be able to evolve bigger brains than they already have. Maybe if we designed them some super foods, but that seems to be cheating, to me.

MonkeMischief@lemmy.today on 18 Mar 16:51 next collapse

exasperation@lemm.ee on 18 Mar 21:29 next collapse

While we humans eat a lot, something like 50% of our calories are going to our brains.

I don’t think that’s right.

This article says that about 20% of an adult human male’s resting energy expenditure goes towards supporting the brain’s metabolism. Obviously for more active people, the higher denominator of total energy expenditure will mean an even lower percentage of energy being used for the human brain.

Flying is energetically expensive to start doing, but pays off in efficiency once an animal moves a far enough distance. How many calories does a goose need to consume to fly 4000 km, and how does that compare to terrestrial species like deer or wolves?

Digestive_Biscuit@feddit.uk on 18 Mar 22:27 collapse

Most birds are extremely light and efficient. Their bones have evolved to be light weight to help with this. Some species even fly in a V formation to conserve energy.

Evolution doesn’t mean get better or smarter. It just means the species can survive and keep reproducing. Emperor Penguins in Antarctica for example, where they nest in a place where there are no predators. It seems insane the hardship and their silly walk which takes forever. But it works.

psud@aussie.zone on 19 Mar 08:17 collapse

Evolution isn’t aimed. A T-Rex needs to be good enough to hunt enough food.

Our ancient ancestors smashed the skulls of animals killed by African predators to eat the brains, smashed bones to eat the marrow.

Later as our ancestors became bigger and stronger they hunted and needed to communicate with each other to effectively track and take down an animal. Maybe they needed twenty words. Chickens have three words (or cluck patterns)

At the same time women collected stuff and needed to share how to identify this from that with younger women. They might have needed a hundred words.

Then those who could talk better were more attractive to the other sex than those who couldn’t (even now being well spoken is attractive) then a few millions of years later we’re making stone knives, hammers, axes; then ten minutes later aeroplanes and machine guns

In short: we had it hard enough we needed to share information. We later found communication sexy. T-Rex had no such trouble. We seem to be the only animal that solved “scavenging is dangerous” and “hunting is hard” with talking to each other rather than by getting bigger and getting claws or vicious teeth

I understand we selected for tall by fighting humans

wewbull@feddit.uk on 19 Mar 21:43 collapse

Evolution isn’t aimed.

I realise that, but the use of tools and sharing of ideas may well have had advantages against the T-Rex. Just as I’m sure they’ve helped us against things that would eat or kill us.

We seem to be the only animal that solved “scavenging is dangerous” and “hunting is hard” with talking to each other rather than by getting bigger and getting claws or vicious teeth

Right, but why are we the only ones to solve it that way? Some lesser “dinosaur” could have evolved tactics to fight bigger predators through basic weapons (sharp sticks), but no evidence of that exists.

An advantage is an advantage, so I think it’s reasonable to ask why mammals and not murder chickens came up with it.
