It should be noted that we live a world of truly insane shit.
2 years ago a marine biologist discovered what he concluded must've been a kraken's lair, indicating that the kraken may have been an actual living creature at one point in time, in the form of an inconceivably massive octopus/squid-like creature.
The leviathan, "Livyatan Melvillei" (named after the biblical Leviathan and in honor of Herman Melville), was recently discovered. It's an extinct cousin of the sperm whale, very slightly larger than both the sperm whale and megalodon at about 60" long, except with VASTLY bigger jaws and VASTLY bigger teeth than either.
The largest bite and largest teeth of any creature ever discovered.
Megalodon was a 55" long cousin of the Great White shark.
Up until 200 years ago New Zealand was home to the Giant Moa Bird - a 12' tall 500lb cousin of the ostrich. This was a monstrous bird that was hunted to extinction by modern humans.
This week they discovered that there was an extinct gigantic 3 foot sharp-toothed species of carnivorous platypus that once roamed Australia.
Sarcosuchus Imperator and Deinosuchus were both titanic 40 foot crocodiles that once lived in Africa and Texas repectively.
Argentavis was a 6 foot tall condor-like bird with a 28 foot wingspan which once lived in Argentina.
The coelacanth and frill shark are both ancient species of fish thought long extinct and dubbed "living fossils" when they were recently discovered to still be alive.
This week they discovered a new species of hammerhead shark.
A new species of scorpion was JUST discovered in Turkey.
Fossils of Lythronax Argestes "King of Gore" - T-Rex's oldest known ancestor were just discovered.
Within the last few weeks we discovered a new species of dolphin.
Within the last few weeks we discovered the Cape Melville Leaf-tailed Gecko, Cape Melville Shade Skink, and Blotched Boulder-frog, all in Australia.
There are completely comical, seemingly implausible, tree-climbing goats that live in Morocco.
A bizarre squid with a human-looking mouth was discovered in the southern Atlantic in 2007.
65" long oarfish live in the oceans of the world. An 18" one just washed up on the Texas shore a couple weeks ago.
A few weeks ago we discovered the olinguito - the first new mammal to be discovered in the Americas in 35 years.
441 new species of plants and vertebrates have been discovered in the last 4 years JUST in the Amazon rainforest.
Titanoboa was a snake that went extinct about 60 million years ago. It was about 12 to 15 m (40 to 50 ft) long and weighed up to 1,135 kg (2,502 lbs).
The Giant Squid is totally normal to us now as a thing that lives in the oceans....and we recently proved that the even bigger Colossal Squid also lives in the depths.
The largest creature to ever live is still alive today - the Blue Whale.
Hell, up until the mid-twentieth century the mountain gorilla was considered a myth.
.
We live in a world that has historically been jam-packed full of all sorts of crazy monsters that we're still discovering left and right, we are CONSTANTLY discovering new creatures living in our world that we were bizarrely oblivious to, and we even rediscover creatures we were sure were long extinct.
I won't rule out anything that appears to be plausible creature that could feasibly exist (like yeti-like creatures, or something akin to a plesiosaur), but I'll totally ignore anything nonsensical (jackalopes).
That said, I won't believe anything until I see proof either.
The fact is that we really don't really know half as much as we think we do about our planet....
