Since first learning about dinosaurs and other frightening prehistoric creatures, one always stood out, the Tyrannosaurus Rex. This monstrous creature stuck in our minds for several reasons, but mostly because he was known as one of the most vicious carnivores to walk this land. Even his name celebrates its reputation for dominating the earth during its existence with Tyrannosaurus meaning tyrant lizard and Rex meaning king. It’s almost hard to imagine that there was ever a creature that was more dangerous or terrifying, but history was filled with giant monsters that can terrorize even a T Rex. Here is a list of ten prehistoric creatures that just might give you nightmares.
This ancient snake is the largest to have ever existed, comparable to the monster anaconda from the Jennifer Lopez movie. Fossils of this reptile have been found in Columbia, with the longest reaching 42 feet and weighed over 2,500 hundred pounds, the same weight of a grown giraffe. Researchers believed this creepy creature was dominantly piscivorous, which means it ate mostly fish. It lived during the Paleocene epoch, an era known for its tropical ecosystem when temperatures averaged 90 degrees Fahrenheit (32 degrees Celsius) which allowed the cold-blooded snake to obtain its huge size. It came into existence right after the T Rex Era, which is may have been a good thing for the lizard king because scientists believe the Titanoboa would have easily crushed it to death.
