We often hear that more and more animal species have been critically endangered and their extinction is just a matter of time. Ruthless human expansion, hunting, destroying natural habitats, climate changes and other factors have are contributing to a species loss rate 1,000 times greater than the natural background rate. Though sad, sometimes extinction can be beneficial for a particular race of species…ours! From 42-feet long mega snakes to Giraffe sized flying creatures, check out these 25 mind blowing extinct creatures you’ll be glad don’t exist.
Native to Southern Australia, Megalania was a giant lizard that became extinct as recently as just about 30,000 years ago which means the first aboriginal settlers of Australia might have encountered this creature. Scientific estimates regarding the size of the lizard vary greatly but it probably could have been about 25 feet long which would make Megalania the largest terrestrial lizard known to have ever existed.
One of the longest-lived pre-historical creatures (310 – 250 million years ago), Helicoprion is a genus of extinct, shark-like holocephalid fish most memorable for its spirally arranged clusters of teeth, called tooth whorls. Helicoprion may have grown up to over 13 feet long but its closest living relatives, the chimaeras can reach only 5 feet in length.
Unlike its modern relatives, the Entelodon, was prehistoric pig-like mammal with a ravaging appatite for meat. Possibly one of the most monstrous-looking mammals ever the Entelodon stood on all fours and was almost as tall as a man. Some scientists suggest that Entelodonts were even cannibalistic. Hey, If they could eat their own, they could certainly eat you.
Native to probably all Cambrian seas, Anomalocaris – meaning “abnormal shrimp“ – was a genus of marine animals closely related to ancestral arthropods. Scientific research suggests that it was a predator feeding on hard-bodied sea creatures, including trilobites. They were notable especially for their unique eyes that, equipped with 30,000 lenses, are believed to be the most advanced eyes of any species of its time.
Meganeura is a genus of extinct insects from the Carboniferous period which resemble and are related to the present-day dragonflies. With wingspans of up to 26 inches, it is one of the largest known flying insect species that ever lived on Earth. Meganeura was a predator with its diet consisted mainly of other insects and small amphibians.
