Going to need a bigger boat
A haunting creepy-crawly
Giant short-faced bear
Argentavis
Sarcosuchus imperator, which translates to "flesh crocodile emperor," lived in Africa about 100 million years ago. It is believed to have grown to be as long as 40 feet. It is thought to have weighed as much as 8.75 tons, which is 17,500 pounds. Experts believed that it skulked the river banks, making its meals from fish and the like that it crushed in its jaws (click here for a photo of its skull next to a human). With jaws that measured around 6 feet and contained as many as 100 teeth, experts believe the SuperCroc also ate small dinosaurs.
Argentinosaurus
The next time you're looking at a six-story building, take a moment to consider that 100 million years ago, you could have been staring up at an Argentinosaurus. At 120 feet long and weighing 100 tons, this creature holds the title of the biggest dinosaur ever to walk the planet. While much about this dinosaur remains a mystery, experts do know that it had a long neck, a long tail and a relatively small head. One fossilized vertebra alone measures more than five feet crosswise. This planteater was first discovered in Argentina in 1988.
