There Are A Lot Of Ai Tropes. I Chose The Six That I Love Most, And I've Turned Them Into A Quiz.

I found a really cool Youtube channel called History of the Earth that covers topics in the incredibly distant past. I'm talking billions of years ago. And learning how the Earth itself formed and where water came from and about the very first single-celled organisms is just like... woah. WOAH.

It's wild that billions of years ago there were just some bacteria hanging out in the ocean and now we have all this. It's really humbling and puts into perspective how precious our planet is. How precious life is.

WHY THE TRIASSIC????

What the FUCK is so WEIRD about the Triassic?

Well I will TELL YOU! 

Okay so first of all, the Triassic is SUPER DUPER OLD. In the grand scheme of the Earth, sure, it happened relatively recently, but working on the scale of the entire geologic time span of the Earth’s existence is not exactly fair: 

I mean, animals that we can recognize today didn’t show up until that line in the Phanerozoic (Hadean is the oldest stuff), so like, it’s smack dab in the middle of THAT 

Look, basically, here’s what happened: 

- The earth Formed. Life Appeared. Chaos reigned (4,600 million years ago until 4,000 million years ago) 

- Life began to become more complex. Some life began to stick its blueprints inside of pockets so they’d be safer. They then swallowed other life forms that were better at getting energy, but kept them around like a buddy inside of them. Some of these guys could make a shitton of oxygen. This made the earth cool and a lot of shit die out super duper quickly. Extinction rate unknown. (4,000 million years ago until 2,500 million years ago) 

- Climate change and fluctuating oceans allow life to start to group up together into SuperLife aka Multicellular Things. These multicellular things got more and more complicated. Some became animals and started moving around a lot. Some plants went on land. Some things were super weird looking and mysterious. LOTS of experimentation by life. Things start to change and a lot of these early experiments go extinct. Extinction rate unknown. (2,500 million years ago until 541 million years ago) 

- Animals can suddenly burrow underground and go absolutely apeshit and diversify faster than you can say “wait a second whAT THE FUCK IS THAT”. Ice Age causes Death, 85% of species die out. (541-444 million years ago) 

- Fish suddenly have a chance to be weird too and some of them decide, what the heck, let’s crawl onto land. Why not, right? Some other animals decide to join them. Plants make everything super cold, 75% of all species die out. (444-359 mya) 

- Land-vertebrates start to diversify. They try out a lot of new things, but there aren’t a lot of them yet. So there’s still a lot of experimentation in body plans. Mammal-relatives are actually some of the most diverse ones. Reptiles are fairly rare. A GIANT MASS EXTINCTION CAUSED BY A GIANT LAVA FIELD EXPLODING KILLS ~95% OF LIFE ON EARTH. (359-252 mya)

- NEW animals get to try to diversify and do lots of crazy shit in the wake of SO MANY JOBS IN THE ENVIRONMENT GETTING CLEARED OUT. Reptiles diversify so fast you don’t know what the heck is happening. Other animals also take this opportunity to do new and weird shit. VOLCANOS EXPLODE, KILL ~80% OF LIFE (252-201 mya) 

- Dinosaurs finally get to do fun things now that other reptiles are no longer being weird. Modern life starts to show up. (201 mya-today). 

BASICALLY: 

- Land Animals had only just started to diversify and try out new funky things with their bodies in order to cope with the challenges of terrestrial life 

- Then a giant mass extinction killed everything. Mass exinctions are bad news for a lot of shit that’s specialized for the environment that’s been destroyed, BUT it allows things that make it through to have a chance to try out new shit to fill all those empty jobs in the environment 

- So, generalist reptiles, who hadn’t had a chance to do jack diddly squat before, now suddenly had the whole planet to play with. And the other animals around them, from mammal-cousins to amphibians to fish to insects to other invertebrates, also got to try out some new stuff in this new world 

- AND THEN ANOTHER MASS EXTINCTION HAPPENED RIGHT AFTER THAT RESET THE CLOCK AGAIN

This means that the TRIASSIC has some of THE MOST UNIQUE ANIMALS TO HAVE EVER EVOLVED IN EARTH’S HISTORY. Experiments were tried, rapidly, and MANY were lost RIGHT AWAY. It’s not like the life that evolved after that, which was honestly similar to what we see today - or those that evolved after the end-Cretaceous extinction, which was even more like today. These were weirdos that appeared and were wiped out before they could continue on to today 

And, because this was a rapid evolutionary period, we see the starts of many of today’s modern groups of animals, and they’re super weird, too! 

Honestly, the only weirder period in Earth’s history is the Cambrian Explosion, when animals first started doing anything notable at all 

On top of THAT, the ENTIRE EARTH was ONE GIANT SUPERCONTINENT called Pangea! Everyone could go everywhere! There were no terrestrial barriers to movement! So many creatures spread all over the globe. It was a HOTSPOT of biodiversity and a major turning point in Earth’s History

But, because the dinosaurs that evolved in the Triassic were kind of Meh, it doesn’t get enough press!!!!!!!!!!!!! 

So, we’re going to cover the Weird and Wonderful animals of the Triassic - we have a carefully curated list of Weirdos ready to take Tumblr by storm, and we hope you’ll enjoy learning about these amazing animals right along with us! You’ll have to wait till tomorrow to see them, though - don’t want to give away the surprises! 

GET! PUMPED! 

IT’S TRIASSIC TIME!

Savage 10 metre fish of the Silurian and Devonian Heavily armoured piscine torpedoes with fierce teeth roamed the oceans in the early days of fishes, in fact the Devonian era is called the age of fishes by palaeontologists as they had a huge burst of speciation and diversified to fill most marine ecological niches during this time. The now extinct (fortunately) class known as placodermi (plate skin in Greek) was the apex predator of these long gone waters, and thrived from 438 to 358 million years ago, dying out at the end Devonian mass extinction (one of the lesser ones).
