#8 Glyptodon
Can you imagine an armadillo the size of a Volkswagen Beetle? That pretty well sums up the size of this creature that lived during the Pleistocene. This huge armored mammal was about 11 feet long (3.4 m), and weighed about 4,400 pounds (1,996 kg). With its squat limbs and rounded, bony carapace, it also had a tail armored in bone. Although it resembled a turtle, it was actually related to armadillos. Experts think humans may have played a part in Glyptodon’s extinction. That’s based on evidence suggesting hunters may have used the carapace as a type of shelter during harsh weather.

#7 Argentavis Magnificens
Thanks to their great size, there’s been speculation that these prehistoric birds might have provided the basis for the legendary Thunderbirds found in Native American folklore. The Teratornithidae (tair-uh-torn-ith-uh-day) was a family of huge birds that existed in North and South America until the Late Pleistocene. Argentavis Magnificens was an enormous member of that family, whose remains were found in Argentina where it flew some 6 million years ago. This was one of the world’s largest flying birds with an estimated wingspan exceeding 20 feet (6.5 m), while weighing about 160 pounds (72 kg). Imagine if a bird that size flew overhead right after you washed your car!

#6 Edestus
This animal is related to Helicoprion, the shark-like fish infamous for its spiral-saw set of teeth. Like Helicoprion, Edestus is known only by its unique teeth, which grew in curved brackets. Because those teeth never fell out, experts say its mouth would have resembled a huge set of pinking shears. The animals probably used their deadly teeth to slash at their prey before swallowing it. There’s still a lot to learn about these beasts, including their exact size. Most sources indicate they would have been comparable in size to the modern great white shark at about 20 feet long (6 m).

#5 Wicked Big Wombats
Even after going extinct some 46,000 years ago, Diprotodon is still the biggest marsupial ever known to have existed. Fossils of complete skeletons have been found in their native Australia, where the creatures are also called Giant Wombats. The largest specimens go about the size of a hippo. Measuring nearly 10 feet (3 m) from nose to tail, they could weigh more than 6,000 pounds (2.7 metric tons)! DId you know that certain Aboriginal tribes have identified bones of Diprotodon as belonging to the mythical Bunyip?

#4 Giant Shrimp
This critter was found in great numbers swimming the planets seas more than 500 million years ago. While it’s scientific name is Anomalocaris , it might be better recognized as the Abnormal Shrimp. And considering that these creatures could grow more than 3 feet long (91 cm), that would make for an abnormal shrimp. Their unusual physical traits included a pair of compound eyes on stalks that had some 16,000 lenses. And their mouth had 32 overlapping plates which were used to crush their prey.

#3 Cameroceras
This monstrous mollusk inhabited Siberian waters some 470 million years ago. By some accounts it may have been the largest cephalopod that ever known to have existed, and is an ancestor of modern day squids and octopuses Some estimates of its body size give it a length of 30 feet (9 m), although some experts debate that. It’s thought that the animals used their tentacles to capture sea creatures including fish. Due to their enormous shells, the largest specimens may have remained permanently on the seafloor.

#2 Utahraptor
The Velociraptors portrayed in the Jurassic Park movies were much larger than their prehistoric counterparts. Those ancient animals would have been no larger than a turkey. It’s the Utahraptor that was closer in size to the movie raptors. Except these creatures were even bigger. They could weigh more than 1,000 pounds (500 kg) and grow nearly 20 feet long (6 m), roughly the size of a polar bear. Using razor-sharp hind claws that measured more than 9 inches long (23 cm), they were able to take down prey larger than themselves. Did you guess that remains of this beast were found in the US state of Utah?
