List Rules Vote up the dinos who may be fossils yet are still more avant-garde than you.

For 180 million years, dinosaurs reigned over every corner of the Earth’s surface. During this period of natural history, known as the Mesozoic era, these prehistoric titans evolved to fit nearly every habitat and niche under the sun. The results were some of the most amazing creatures to ever walk the Earth, with many unique shapes and body types that would never be seen again. While there are plenty of wrong things people used to think about the dinosaurs - like most of them are vicious monsters - not all of these animals are defined by their teeth and claws. Some are cute, others are impressive, and a few are just downright weird.

The fossil record is full of scary extinct dinosaurs, with some of the crazy dinosaurs sporting some of the most bizarre adaptations thanks to evolution. There are dinosaurs that managed to grow stubbier arms than the T. rex, while at least one looked like a buck-toothed chicken. Their are bird-like dinosaurs who rock primitive feathers and others that are covered in spines, scales, and armor. These bizarre-looking dinosaurs you won't believe are real shining examples of just how strange evolution can be and how dinosaurs truly are some of the most interesting animals to ever exist.

Halszkaraptor Was So Weird Scientists Thought It Was Fake


 

Halszkaraptor's skeleton appeared so unusual that at first, experts didn't even think it was real. Andrea Cau, an investigator from the University of Bologna, explains:

"It was so strange that we suspected that it might have been a chimera – a mix of different skeletons glued together. It wouldn’t be the first time."

But once the chunk of rock containing the fossil was scanned, the scientists determined that this creature was for real. It seems to have been amphibious, though its features look more like those of a duck or a swan than a reptile. It presumably ate fish.

Therizinosaurus Had The Longest Claws Of Any Animal

Therizinosaurus could be found roaming around in Central Asia between 75 and 70 million years ago. While these monstrous beasts may look like the dinosaur version of Edward Scissorhands, they were probably gentle giants who only used their claws for self defense and to gather food. Their claws are believed to be the longest in animal history, and are able to grow over three feet in length. Unfortunately, a full skeleton has never been discovered for this animal, so there are many unanswered questions as to what the therizinosaurus was really like. Scientists have not even found a skull, so we can’t even be sure of what or how they ate.

Concavenator Probably Had Some Back Problems

This odd theropod is Concavenator corcovatus, a carnivorous dinosaur that roamed Europe about 130 million years ago. The noticeable hump on its back is unique for these types of dinosaurs, and it has left scientists puzzled since its discovery in 2003. Researchers have thrown out all sorts of theories about the hump, speculating it could be used for mating, storing fat, or maybe that it was purely decorative. Another one of concavenator’s bizarre features are the bumpy protrusions on its arms.

These are similar to the anchor points for modern bird feathers, but scientists believed concavenator most likely had non-scale protrusions that dangled from them. The debate is still ongoing as to the true nature of these strange knobs.

Incisivosaurus Had Ridiculous Buck Teeth

Possibly one of the most absurd creatures to ever walk the Earth, incisivosaurus is a buck-toothed dinosaur that lived 128 million years ago. This bird-like dinosaur is unique for it’s bizarre teeth, a rare quality in animals outside of mammals. Most reptiles have one type of tooth, but incisivosaurus had both smaller, sharper teeth, as well as their distinctive front teeth. Some scientists believe they were either herbivorous or omnivorous, another trait that makes them distinct.

Amazingly, their strange physiology helped reveal some major secrets about another type of dinosaur, the oviraptor. It was believed oviraptors may have been birds who had simply lost their ability to fly, but it was later discovered incisivosaurus had actually been an early ancestor to the oviraptors, disproving the theory they came from birds.
