THERE ARE WAY TOO MANY AMAZING ANIMALS THROUGHOUT EARTHS HISTORY TO PICK FAVORITES
There is no universe in which you could make me choose between fricken gorilla horses (Chalicotheres), BEEG BIRBS (Elephant Bird, Moa), Probably the best pet nature has ever given rise to if only we didn't exterminate them within a century of discovering them (Dodo Bird), A dinosaur who's name literally translates to FLESH-EATING BULL (Carnotaurus), The humble honeybee that works it's ass off to make my tea taste sweeter in the morning, COELACANTH COELACANTH relicanth COELACANTH COELACANTH HOW CAN ANYONE NOT LOVE THE COELACANTH ACTUALLY SPENT 65 MILLION YEARS AFTER WE THOUGHT THEY WENT EXTINCT DABBING ON THE NONBELIEVER PALEONTOLIGISTS FROM THE BOTTOM OF THE SEA, Giant adorably fluffy water guinea pigs that give no fucks (Capybara), GAY BOWSER (Galapagos Giant Tortoise, and to a slightly lesser extent Aldabra Giant Tortoise), HOLY SHIT THIS FUCKER BASICALLY EVOLVED A GUN (Pistol Shrimp, I'm serious these guys exist), It is 2021 and Paleontologists still barely understand what the hell this alien looking thing is supposed to be (Tullimonstrum, better known as the Tully Monster), Screw you amphibians, I'm returning to worm (Caecillians), Actually just Jhen Mohran from Monster Hunter if he was 8 inches long (Sandfish Skink), and probably thousands more I could think of just off the top of my head!
