Arrrr, here be krakens matey! Well, not really, but kind of... especially when you look at prehistoric waters.

You know how I've reiterated that you shouldn't get into the water, no matter how bad things get on land, well... there is ONE exception to this rule. 0:00Nature’s Unspoken Rule And The Period That Broke It 00:45Geography & Oceanography 02:15What Lived In The Oceans & Seas 03:56What Caused Life In The Water To Be So Unscary? 04:35The Opposite Story On Land & Earth’s Old Rulers 05:11Earth’s Original Sabre-Tooths (Gorgonopsids) 06:30The Largest Predator & Gorgon Around 08:45Permian Russia Was A Problem 09:18The Giant Gorgonopsids That Ruled Africa 10:47More More More Gorgons 11:27The Gorgonopsid’s Nemesis (Therocephalians) 12:18First Animals To Evolve Venom? 12:50Jaguar Sized Predator With A Lion Sized Head 13:35Largest Non-Gorgonopsid Land Carnivore 14:25Other Late Permian Carnivores 15:20Amphibians 16:30Herbivores & The Largest Animal On Earth 18:28Prehistoric Skies WITHOUT Pterosaurs 19:21Mother Nature Wanna Kill You Too (The Great Dying)

The ancient Greeks & Romans did a lot during their times, spreading far and wide, which also led them to seeing a lot too. These sights included landscapes, other civilizations, and even exotic animals too, some of which are sadly no longer around today….

People often ask about how bad the asteroid that struck the dinosaurs was, or what would happen if it hit earth today, but no one's really asked just how long the dinosaurs survived after d-day...

The Ice Age was no doubt one of earth’s most questionable phases, being a very brutal time that led to brutal animals, and sometimes these animals were so ferocious that they made other monsters seem a bit dull, one such animal that did this was the Smilodon.

Jaws, the most iconic shark film of all time, is likely the source of thalassophobia in millions of people worldwide. And it's not hard to see why, cause… well sharks just look really scary, far scarier than whales, but there was one whale, now far gone, that actually would’ve made for one terrifying jaws, the Livyatan.

Quick, someone tell Caesar

If you thought Jaws was scary, wait until you see what prehistoric sea monsters lurked in the depths of this ocean...

Dinosaurs in general are pretty weird, but just how weird did they get? Well it turns out, pretty dang weird...

Can it get any more American? Supersized, comeback story, the name - Alamosaurus has it all!

Titanoboa ain't top dog anymore

Everyday it's estimated that over 100 species die, that's quite a lot, but let's face it most of these species we never hear of, so we don’t really think often about this stat. Yet, once in a while a species well-known to people disappears, causing us to stop for a minute and ponder…

I wonder who was the favorite child...

10,000 years ago of all kinds of titans roamed America, and I mean ALL KINDS, we're talking giant beavers, mammoths, wolves and more... Thankfully for us we no longer have to worry about a not-so friendly Smilodon jumping us while out running, but the same could not be said for the Native Americans, who not only lived alongside them but also managed to thrive.

Our ancestors had it ROUGH. On the bright side, there was a good chance you would've been the world's best at something...

If you hate bugs, or any other type of creepy crawlies, you probably shouldn't listen to this

Yup, your reading the title right, Africa wasn't always the land of giant cats, rather big fuzzy wuzzy bears.

Flipper wasn't so nice and wholesome back in the day. For some reason it seems like every animal we all adore was at one point quite monstrous as demonstrated by the Ankylorhiza, a prehistoric nightmarish dolphin.

Everything was messed up and more dangerous during the Mesozoic. You had theropods, titanic sauropods, fortified ankylosaurs, giant crocs, and frogs. Yes, that's right even the frogs were messed up as demonstrated by Beelzebufo the dinosaur eating giant, that may have been the largest frog to ever live.
