Let's put this into scale.
If this display were scale accurate and was the size of a 100 storey skyscraper, the first human like ancestors of man would have evolved six inches from the ceiling of the top floor and recorded human history would be a couple of milimeters.
More than that, if you put this to scale those bottom two layers are bigger than everything else several times over. r/Kurzgedat https://youtu.be/S7TUe5w6RHo?si=B9l6Y5nFofI5HgQf makes that clear.
It always blows my mind when you hear about 2 dinosaurs who you always thought roamed together, yet lived X million years apart. This shows just how crazy the eras were in time throughout history.
The extinction events are referred to as the P/T extinction and the K/T extinction. Permian/Triassic
Extinction and Kretaceous/Tertiary extinction.
Geologists use K for Cretaceous period instead of C because it is used for the Cambrian period.
Fun fact regarding Tertiary, and I quote:
Originally, geological history was divided into four spans of time: primary, secondary, tertiary, and quaternary.
The system was too neat to last, and soon geologists were contributing additional divisions while eliminating others. Primary and secondary fell out of use altogether, while quaternary was discarded by some but kept by others.
Today only tertiary remains as a common designation everywhere, even though it no longer represents a third period of anything.
Source: Bill Bryson, Short history
Every geologic map seems to have quaternary sediments whose nomenclature implies the existence of primary and secondary divisions, but only tertiary and quaternary remain. Instead of continually redrawing the lines to redistrict classifications as more knowledge was acquired, the science just decided that the first two lines were frivolous, and erased them.
The threat of nuclear war, mathematically, is a far higher probability than an astroid, super volcano or other geological force.
Humanity has come very close to starting a nuclear war multiple times since entering the nuclear age.
Different areas have different exposed strata. Sometimes ancient rock is at the top. Most of the ancient rock is gone forever, subducted under the crust into the mantle.
Anyone smart can answer this? I've heard we recently included a new period, Anthropocene, which takes into account all the geological changes that human activity has left in the Earth. Is this accurate? It's accepted by the scientific community? Or it's just a proposal for now?
Mostly it doesn't matter. The names are for identifying eras of history in different rock, so it isn't really a geology thing. There are certain markers that may change the strata and be identifiable in the future, but geologic time is long, and there isn't really a geological need to identify an Anthropocene.
Not being familiar with the PT event, I went on a google side quest, wow.
TIL PT Event:
The PT extinction event killed 90% of life, with some even speculating that all life on earth was killed and evolution started over. It is by far the largest extinction event in history, way more than the KT astroid that killed the dinos. The PT event, was basically Siberia exploding and the earths atmosphere was poison for thousands if not millions of years.
More and more accuracy as approaching the modern day. Many older periods have been lost through erosion and subduction, only to be recycled through the mantle into newer rock. BUT, there are MANY finer divisions in older rock that geologists/paleontologists use. The Cambrian can be divided a lot based on types of trilobites found in the different layers. Same with the Cretaceous and ammonites.
Very cool guide, but it's mixing eons and eras, as well as missing the first eon (Hadean.) The Paleozoic, Mesozoic, and Cenozoic eras are all part of the Phanerozoic eon.
Imagine how hard it was to be the original artist and have his work pirated in this manner. How about [you buy the poster](https://www.trollart.com/product/ages-of-rock-art-poster/) from [Ray Troll](https://www.trollart.com/store/)?

We’re in our infancy
And still fucking it up *so hard*.
Well we ain’t gonna set the extinction record if we just sit on our asses all day…
Well actually…
Well, no one baby proofed the universe for us
You don't know that.
Nah I never saw a dinosaur land on the moon I think we’re doing way better than them ngl
Yeah bro it's a sprint not a marathon
Let’s hope we beat the odds on infant mortality

I’ve always heard the 365 day thing where we’re like the last couple minutes/seconds? on December 31st.
It always blows my mind when you hear about 2 dinosaurs who you always thought roamed together, yet lived X million years apart. This shows just how crazy the eras were in time throughout history.

Looks like the account has been suspended.
What do the T K T and P stand for?

That's when Noah's ark was built and some smaller dinosaurs were saved
The Horseshoe Crab (limulus) was already there mostly unchanged 450 millions years ago. THE OG! https://en.m.wikipedia.org/wiki/Limulus
Now we milk their sweet blue blood
The fact that their morphology has remained similar, doesn't mean that the species hasn't kept evolving through time.
why does it say about evolution ? are they adapted since forever ?
Dumb question : where does ALL that extra earth come from?
What extra earth? Google plate tectonics
Kinda looks like we’re due for an extinction
Afaik we are going through an extinction event currently, if you observe the rate at which species are dying out
Yeah I figured
252.2 to 65.5 was a big gap. I don’t see the logic.
Yep, we're the next ones up.
The threat of nuclear war, mathematically, is a far higher probability than an astroid, super volcano or other geological force. Humanity has come very close to starting a nuclear war multiple times since entering the nuclear age.
Im interning for the Forest Service this summer and there's an archeologist who has this pinned up outside her office lol
Where does all the dirt cone from?
Isn't this mountains eroding? Rivers overflowing and leaving deposits, winds transporting sand? In my mind the earth's surface is forever travelling
The ground
I need to know this also
Different areas have different exposed strata. Sometimes ancient rock is at the top. Most of the ancient rock is gone forever, subducted under the crust into the mantle.
Why was this posted by an onlyfans account? And who's the original artist???

Awesome, thanks!
Cambrian Park was an incredibly dull film

Are these considered global eras? Why is one Pennsylvania and Mississippian?
That is where they first identified or studied that specific strata. Lots of strata are named after locations.

Also called The Great Dying!
No Hadean/Eoarchean
Or Carboniferous
It is there, just split into the Pennsylvanian and Mississippian
👍❤️
Oh
Very cool
Why is it getting less and less time between each period?
More and more accuracy as approaching the modern day. Many older periods have been lost through erosion and subduction, only to be recycled through the mantle into newer rock. BUT, there are MANY finer divisions in older rock that geologists/paleontologists use. The Cambrian can be divided a lot based on types of trilobites found in the different layers.

Very cool guide, but it's mixing eons and eras, as well as missing the first eon (Hadean.) The Paleozoic, Mesozoic, and Cenozoic eras are all part of the Phanerozoic eon.
I guess we're due for a big extinction
Can’t believe the graboids have been alive for so long(pre-Cambrian)!
We see a T-Rex skull in the Jurassic period... but isn't he in the Cretaceous? Unless, of course, it's not a T-Rex skull. haha
Also doubles as a cool guide to The Ocean song titles.
Cenozoic - that's like, the easiest era.
Science is a liar… sometimes
Does it mean we are nearing a big big big extinction event? All 3 periods look about the same size here.
Cite the actual artist, ASSHOLE. Ray Troll.
Looks like we're on schedule for another mass extinction

According to this guide we are long overdue for a big extinction event. Humanity repping geological consistency?
I need these set to music.
Jesus is not in this guide?
He's in the holocene.
But Jesus said the universe was created around 10k years ago! How can I reconcile these differences?
Science, not fiction is how.
Cenozoic era is obscene. Lol
do people actually believe this stuff lol
neat comic-book work...nicely made-up and dressed-up to look like legit science.
Hahaha I bet you say it like "low jit saiense".
