  • Dimetrodon on Random Famous Prehistoric Animals You'll Be Surprised To Learn Aren't Actually Dinosaurs

    (#2) Dimetrodon

    Contrary to popular belief, the sail-backed dimetrodon is not a dinosaur. It's actually a synapsid, a group of animals that is much older than the dinosaurs and a precursor to modern mammals. If you look far back enough in your family tree, eventually your relatives will start looking a lot like dimetrodon.

    Dimetrodon thrived during the Permian era, 35 million years before the first dinosaurs had even evolved. There were many different species, but the largest and most famous was a 10-foot long monster. They had serrated teeth perfect for carving flesh, making them one of the Permian's most successful predators.

  • Dimorphodon on Random Famous Prehistoric Animals You'll Be Surprised To Learn Aren't Actually Dinosaurs

    (#7) Dimorphodon

    Dimorphodon is one of the most bizarre looking pterosaurs to have ever lived. It looks like a cross between a bat and a pterodactyl, with the head of a tyrannosaurus. Terrorizing the skies almost 200 million years ago, it is believed that dimorphodon was one of the first large vertebrates to take to the sky. They were relatively small, growing to be a little over three feet in length. Hidden inside their unusually large skulls was a very small brain.

    Extensive research has been done to try and understand how they were capable of flight even studying the tree-dwelling gliders they may have descended from. It is believed they flapped their heavy wings to aid in flight, much like modern birds.

  • Plesiosaurus on Random Famous Prehistoric Animals You'll Be Surprised To Learn Aren't Actually Dinosaurs

    (#5) Plesiosaurus

    • Plesiosaurus dolichodeirus

    The inspiration for the Loch Ness monster, the long-necked plesiosaurs were a group of marine reptiles whose unique appearance made quite an impact on the collective unconscious. Plesiosaurs were a diverse group of animals, some of which had much shorter necks than the most commonly depicted species. The plesiosaurus was one of the first fossils ever to be discovered, so this animal has a long history in the paleontological world.

    It is believed that they developed their long necks in order to easily scavenge food from the sea floor. Despite many inaccurate representations, plesiosaur necks were actually pretty inflexible. Researchers have also determined that these odd animals most likely swam in a way that would look pretty similar to modern penguins.

  • Pteranodon on Random Famous Prehistoric Animals You'll Be Surprised To Learn Aren't Actually Dinosaurs

    (#6) Pteranodon

    Another member of the pterosaur family, the pteranodon was the much larger cousin of the pterodactyl. They had a massive wingspan that could stretch to twenty feet. Pteranodon was sexually dimorphic, meaning that both sexes had their own distinct appearance. The males were much larger than the females and sported a large, bony crest at the back of their skulls. It is believed that they lived by the coast, possibly dipping close to the water to scoop fish into their massive bills like pelicans.

  • Mosasaurus on Random Famous Prehistoric Animals You'll Be Surprised To Learn Aren't Actually Dinosaurs

    (#3) Mosasaurus

    Although these aquatic reptiles are featured in the movie Jurassic World, they didn't live during the Jurassic period and aren't true dinosaurs. Mosasaurs are thought to have evolved in the early Cretaceous period, the last epoch before the extinction event that wiped out most large life forms.

    These giant sea-lizards were ferocious predators known for their powerful bite, but they were also highly evolved and sophisticated organisms. Mosasaurs are believed to have been warm-blooded, much like their dinosaur cousins, and there is evidence that they gave birth to live young.

  • Glyptodontidae on Random Famous Prehistoric Animals You'll Be Surprised To Learn Aren't Actually Dinosaurs

    (#10) Glyptodontidae

    • Glyptodontidae

    Glyptodon is an extinct type of mammal that lived relatively recently, only dying out about 12,000 years ago. These giant relatives of the armadillo were completely covered in armor, with some even sporting morning-star style clubs at the tips of their tail. Even though they are mammals, they are often confused with armored dinosaurs like ankylosaurus.

    Humans were known to hunt glytpodon for their meat and armor, which some experts believe was used to create small homes. They could be found all across the Americas until their extinction, which is believed to have occurred due to a combination of human hunting and climate change.

About This Tool

The earth has existed for about 4.5 billion years. With the current technology, it is still impossible to explore the history of the prehistoric animals that once existed on this planet. When it comes to ancient flora and fauna, most people know only the dinosaurs that already extinct a long time ago. There are many ancient animals people should know, who have shared the world with humans and other species.

With the exploration of the earth, humans have discovered some prehistoric creatures that still exist today, some have experienced multiple periods of evolution to adapt to the changing survival environment. The random tool introduced 12 famous prehistoric animals.
