The Late Jurassic Morrison Formation was one of the most brutal places to ever exist. You had giant sauropods and cannibalistic theropods roaming about, and still somehow, things got even crazier when you looked at some of the 'smaller' dinosaurs, with one herbivore in particular actually being more grisly then some of the predators around...

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.

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.
