Modern animals that used to be a giant . 

Fun fact: there was no such thing as a pterodactyl, and as a Dino nerd, it triggers me when people say it’s real

At 1:50 the shark doesn’t even looks scary. It looks so happy, chubby, and cute omg👍🏻💀🔥

Ground sloth is huge! (But in roblox adopt me. _. Soo small)

1:48 THIS IS ALREADY BIG AND SCART BUT WHAT? UTS EVEN SCARIER IN THE PAST AHHH

mouse is transformed in the past an orginary brown capybara

the vid: shows guiena pig as a guiena me who has a guiena pig : looks at guiena pig is fear

The second Sloth be like - *I should look Hot or Ur Mean*

2:09 shows art that they probably stole

1:51 the sharks is like big chungess he’s like cut but dangerous

A chickens closest extinct relative was probably the avian dinosaurs, which pterosaurs weren't in that group, Pterosaurs were archosaurs, but besides that, they weren't related to chickens. Most likely they would be related to prehistoric birds, or avian dinosaurs.

0:58 I swear I would be crying if that was a picture of Ross during Season 7 Episode 10 of Friends

I know that the megalodon is big, but I never knew it was that big.

Chickens closest extinct relevant was T. Rex. Also Megalodons were huge but not huge enough to be able to swallow a carrier ship

My mom would faint if she saw this

Chickens were not related to pterosaurs. Even though chickens fly (kind of) that doesn't mean it's related to an avian prehistoric group of reptile known as pterosaurs.

1:11 that shirt looks modern.. time traveler proved

Fun fact Megaladon was bigger than the sharks of Jaws. He was 50-60 feet long.

For the last time crocodiles were not in the dinosaurs😿

Pterodactyls weren't so big, but deinosuchus wasn't a joke, it literally ate dinosaurs related to apatosaurus that reach even bigger height

If your wondering how a giant shark and a double size anaconda died (megalodon and titanoboa) Also this is according to research Megalodon:the reason was they were wiped out because of great white sharks Titanoboa:basically climate change

mmm yes chickens are definitely related to pterodactyls (disclaimer they are in no way shape or form related unless you take the fact that reptiles evolved into birds)

I was laughing so Hard wenn I saw the pterodactyl after the chicken 😂😂😂😂 By the way this species you shown is actually way smaller then the average chicken 😂😂😂

Dude, idk what ur tryna come up with but the shark looks so chubby and adorable in the photo i wanna✨ SQUISHHHH✨

The huge armodlio rolling around : vroom vroom The other animals: AHGHGHGH

I died when they shown King Kong for the orangutan (or how ever you spell it)

Me:-smiling on sloth-

Me realize that’s why they call me raven as a bird:

I love the art pictures makes it cool

Croc and alligator back then were kaprosuchus, deinosuchus, sarcosuchus Good thing they're all gone now

Idk why but I think it would be cool if there was a animal that had teeth the size of a average house

0:51 I knew it because the armadillo looks like a glyptodon

One is a chicken one is a pterodactyl

Many of these animals appear more than once in this video

In the alligator one The tea Rex was like: dude what are you doing I’m just trying to walk by?

0:07 that’s literally like saying humans are big baboons just because both are primates,this rodent was more related to guinea pigs than to hamsters and mice

When I heard about this I was like: 😨 Chickens used to be huge, snakes use to be huge, sharks used to be ginormous even tho Now they are kinda big but smaller than what they used to be. And the monke use to be big :O

That shark is so cute it is smiling

Another 1 sarcosuchus was the biggest croc but had a smaller mouth than deinonychus

mouse looks more like a capybara in the past

Me hopelessly looking at my fish

The 1st one looks like a giant capybara

Mouse: back in my days we used to be large Chupacabras modern mouse: ITS NOT MY FAULT THAT MOUSE EVOLVED

Finally my favourite animal is included a sloth!

0:05 that looks like a capybara

In mostly in every one of these sorts of videos I see a Titanoboa.

first one is… OK I PULL UP HOP OUT AT THE AFTER PARTY

0:06 Okay they pull up

Brooooooo this gave me chills 🥶😰

1. They’re called pterosaurs, not pterodactyls. 2. Pterosaurs aren’t birds, they’re flying reptiles.

Its just a cigarette I'm scared of ravens now

Chicken was a bird, the pterodactyl was a flying lizard

2:32 BRO THATS SO BIG?!? AND ITS THE ONE WE HAVE NOWADAYS

0:57 I know glyptodon but I didn’t know it was that huge I thought it was a little bit more smaller

My armadillo is a GLYPTODON!?

I can't believe how some people think a megalodon was that stupidly big 1:52

Fun fact:That snake one is from slizzer io

The “giant mouse” is just a giant Cappy Berra

When I saw mouse I thought he meant capybara but when I checked again I was terrified 😰

1:52 THE MEGALODON WHEN IT OPENS ITS JWAS ITS A SIZE HUMAN!

*The song bro its scary*😭😭

Fact: Dinosuchus is actually the biggest dinosaoar or underwater animal its bigger than the T-REX.

Also my sister was a zoo camp and had screaming armadillo

i love how the guiena pig didint fit in the screen

THE HECK DANG THEY MASSIVE

2:32 this shark is already giant

Wow that wasn’t in a mini creatures are really really really crazy all day

the music is my fear biggest fear

1:52 I didn’t know that the megalodon was that big but honestly I don’t think it’s that big that it can eat a boat

the big snakes remind me of dragons

Prehistoric capybaras

They legit compared to a chicken to a pteranodon

Can we see that birds, dogs, alligators, crocadiles, etc. Are basicly hybrids that used to be dinosours, who survived the meteor?

OH SHOOT THATS WHY IM SCARED OF RATS SOME TIMES NOT-

Birds and pterosaurs are two separate bloodlines. Birds much closer to dinosaurs. Also first prehistoric animals in this video reminds more of beavers than mice.

Megaldon wasn’t that big if you all are wondering it’s edited and it would be 2x less the size of that

Your telling me that chicken in my backyard was a dino

Glyptodon is so big! Bigger than us bigger than elephants. But in adopt me roblox SOOO SMALL

Awsome+scary

Chickens are related to tyrannosaurus 💀

Ark players loved this one😂😂😂

0:08 THATS A MULE

That was the scariest creature I ever seen before!?😲😲

2:35 don't tell me I'm crying it's literally finding Nemo 😭😭

In school my home table is a Glyptodon

the thing that triggers me is that how stupid people are thinking the chicken is related to the pterodactyl 0:28

phoberomys pattersoni is capybara now

Sloth are still cute 👁️👅👁️

the gallimimus was also pretty much known as the chicken.

Chickens are actually related to tyrannosaurus

me when i saw the mouse: oh hell no

animals getting smaler humans getting bigger o-O

Sharks are older than trees

glyptodon im dying of laughter UwU

I was different than part fits so well

What???? A chicken is a pterodactyl??? Uuuhh what

Basically in islam people used to be 30m tall and probably this was normal to them

thats a capybara is the creator of that tiktok sped 0:06

I hear ground sloth so many time's...

Chickens use to be T Rexes

Ayoooo the rat from ark megatherium brooo
