[Music] Hey ready for some hypothermia here are 10 extinct creatures that will make your blood run cold see hypothermia huh yeah do you think that dinosaurs were kind of scary yeah think again in its time evolution created creatures so terrifying they make dinosaurs look like cute little babies so do you want to find out which creatures would have completely destroyed our world if they were alive today hey sounds like fun right and let's get started hey as a bonus we might even show you something really gruesome the world's only known literate dinosaur but before we give you all the scary details make sure you subscribe to our Channel and turn on this little notification bell now you'll always be on time for every Brightside hangout counting down from number ten Liopleurodon yeah this video is full of arcane $10 words but I'll try to do my best Liopleurodon was a giant marine reptile from the family of short-necked Plesiosaurus this species lived during the collodion stage of the middle Jurassic period pager asking me how should I know now the typical size of a Liopleurodon varied from 16 to 23 feet but the largest reached over 33 feet considering their length and weight Liopleurodon were predators eating fish squid and smaller marine mammals moreover their nostrils faced forward which was a sign of their excellent sense of smell this also made them one of the best predators of their time and that's still not the only thing that made them powerful their long and flat flippers allowed them to swim extremely quickly so no one could hide when a Liopleurodon decided to hunt unfortunately there are still a lot of unanswered questions about Leo pleura dots but one thing is for sure you wouldn't want to meet them during an exciting trip to the ocean number nine arthropleura time for a millipede to join our list and it's going to be the extinct Thank You arthropleura this millipede lived in the territories of current north eastern North America and Scotland about 315 million years ago the species range from almost one to seven feet in length and were around two feet in width arthropleura 's body was apparently composed of around 30 jointed segments covered by two side plates and one centre play unlike pretty much all the other creatures on our list arthropleura x' weren't predators at simply because these creatures didn't have strong mouth parts so they were entirely plant eaters but even though arthropleura wouldn't pose any serious danger to us just imagine looking down as you felt something brush against your leg and seeing this the record for the loudest scream of all time would certainly be yours luckily when the usual moist climate started to dry out it was time for the Arthur of pleura to go number eight mega lania wait a minute isn't that like the first lady's no okay mega lania often called mega lania priska is the biggest monitor lizard you can possibly imagine yup it's easily the largest terrestrial lizard that ever existed the youngest of its fossils dates back to approximately fifty thousand years ago and if you're from Australia then you probably won't be surprised to know that mega latias live there before their unfortunate extinction but was it really that unfortunate not for us the length of the largest mega lanius reached around 23 feet with a maximum weight of 1322 1370 pounds they were unbelievably active hunters as well and mega lania fossils were often found near kangaroos deers and other large animals of this kind however there's a little twist to all these mega lania facts and it's that these creatures may still be with us in both the nineteen and twentieth centuries there were numerous reports of people seeing creatures that sounded very much like surviving examples of mega lenio there's no actual evidence of this theory apart from those stories but who knows maybe these creatures are still roaming our earth number seven Dunkleosteus Dunkleosteus became extinct around 358 to 382 million years ago during the late devonian period however there wasn't just one Dunkleosteus there was actually ten species of it including dieter le d denis Oni and D magnificus do we get 10 bucks for each of those no dieter le the largest of them was almost 20 feet long most Dunkleosteus fossils were found in North America Poland Belgium and Morocco the largest Dunkleosteus Torelli's had a four-bar linkage mechanism for jaw opening that allowed them to open their jaws completely in just 20 milliseconds they really didn't have that many teeth but it still didn't stop them from eating marine animals moreover there's evidence that allows scientists to conclude that the Dunkleosteus species occasionally cannibalized each other as well just when we thought it couldn't get any more vicious but what do you think is Dunkleosteus the scary one yet tell us about it in the comments below okay let's move right along to number six juh clock taurus juh clock Taurus was a giant predatory sea scorpion that you definitely would want to see during your mesmerizing diving experience though if you did it would certainly be something you wouldn't forget for a long time anyway after analyzing its fossil remains scientists confirm that Jack lop Taurus reached a size of nearly eight and a half feet which makes it the largest arthropod ever these sea scorpions weren't kin tenth with underwater herbs like the harmless arthropleura they prefer to ambush fish with their spring-loaded arms and sliced them up using their claws oh that's a true horror moving scene that happened during the early devonian age well judging from this description they would very much enjoy human flesh as well thankfully the Jakara species became extinct way before we were able to test this horrific theory number five sarcosuchus now why are there still no crocodiles on this list weren't there any scary ones well let us introduce you to the sarcosuchus a distant relative of living crocodiles that lived about 112 million years ago and if you're scared of today's crocodiles this one would make you run even faster these reptiles were almost twice as long and weighed up to 17,000 pounds what a croc the first sarcophagus remains were discovered back in 1946 in the Sahara Desert paleontologists found fragments of the creatures skull vertebrae teeth and other parts with time scientists found even more fragments that help them understand what the sarcophagus looked like according to what's known now it had somewhat telescoped eyes and a long snout with 35 teeth on each side of its upper jaw and 31 teeth on each side of its lower one it's not that hard to hunt with this type of jaw don't you think apparently scientists agree suggesting that sarcophagus might have even eaten some abundant dinosaurs so we'll say that modern crocodiles are enough for us no sarcophagus species please number 4 Gorgon opps long before dinosaurs started to rule the prehistoric world there were other dominant predators out there called gorgonopsids they lived around 260 million years ago terrifying all the smaller species of that time as for their size these creatures were about 10 feet long and weighed nearly a thousand pounds hmm doesn't sound too scary after everything we've already seen today but that's not all you might wonder exactly why gorgonopsids became the main predators of their time we mean they were basically at the top of the food chain easy it was their massive canines that protruded almost beyond their lower jaw plus their legs supported their body from below as opposed to sprawling out to the sides disadvantaged allow them to reach a faster pace and get to their victims more quickly some theories also point out that gorgonopsids may have been warm-blooded which implies having at least a little bit of fur however these are still assumptions with no proof whatsoever but I'm not gonna argue with old Gordy here you want fur you can have fur just don't eat me please number three titanoboa if you can't stand snakes titanoboa would definitely have scared you to death it's believed that this gigantic snake lived in a region that's now part of northeastern Colombia and its fossils date back to about 58 to 60 million years ago titanoboa holds the scary record for the largest snake ever discovered with a total length of nearly 48 feet and a weight of about 2,500 pounds to put that into perspective for you it's basically four times as heavy as a giant anaconda as for its hunting habits - tenable was most probably very sneaky coming out of nowhere and quickly biting its prey in the jugular well I'm not gonna sleep tonight it's possible victims could have been smaller reptiles birds and even crocodiles so you and I would have stood no chance against this monster snake but what would it be like to actually meet a snake that big well back in 2012 visitors in the Grand Central Terminal in New York City were given the opportunity to envision this encounter thanks to a full scale model replica of a to Tana boa it had been created as a promotion for a TV show called titanoboa monster snake and seeing this model definitely sent chills down pretty much everybody spy number two is Megan Marko urops Asst no wait that's a lie it's just Megan your OPS's yeah but I got you didn't I most insects are pretty gross but at least they're small right well not during the Permian period at that time the Megan neuraxis species gigantic dragonflies were the kings and queens of everything they still continue to be the biggest insect of all time with a wing length of 13 inches and a body length of almost 17 inches now the very first fossils of Megan urops aswer actually discovered in France back in 1880 now we know way more about this species for example their hunting methods were very similar to the dragonflies of today the only difference is that Megan er OPS's was able to eat even larger organisms because of their size they detected their victims with their large eyes and used the spine on their legs to get a hold of them however with time atmospheric conditions began to change which might have been the main reason for the extinction of Megan Marco urops Asst oh sorry but after all whatever happens happens for the best it would have been way harder to convince yourself to leave your house if you knew there were giant dragonflies flying outside right number one helicoper en sharks are unbelievably scary but after seeing the helicoper yet the shark from Jaws seems like a cutie this unusual shark like fish was around 290 million years ago living in North America Eastern Europe Asia and no wonder Australia's waters Wow poor Australia just can't catch a break here the most distinctive feature of helicoprion was its circular jaw now just imagine something like this coming towards you man it would have been impossible to return to the water ever again even if you survived the experience apparently this creepy jaw operated like a buzzsaw mowing into its prey and carving it up however here's a plot twist most scientists believe that the helicopter in wasn't a shark instead they're sure it was closely related to the chimeras a type of deep-sea fish well sharks are not helicoprion sprue v' to be incredibly strong since they survived the Permian Triassic extinction event that killed 90% of marine animals and around 70% of terrestrial ones but it only bought them a few million years before their own extinction and that's how evolution saved us all once again and now here's a bonus a dinosaur that was really really really scary the first literate dinosaur yes a dinosaur that could actually read it was called a thesaurus that's right the thesaurus was easy to spot always carrying a book or magazine to read its ultimate downfall always looking for alternative words which meant the same thing t-rex ate him some food for thought so which one of these horrific creatures scared you the most tell us
