Things You Were Lied to About Dinosaurs

You might have heard that all dinosaurs were wiped out 65 million years ago when a 15 km wide asteroid crashed into Earth and caused a mass extinction event. But that - is entirely false.

To be fair, the T-Rex's bad eye sight was a plot point in the Jurassic Park books due to them adding Frog DNA to fill in the DNA gaps. The movies just ignored this small detail and made it seem like T-Rex just naturally had bad eye sight based on movement.

So chickens are dinos.. I'm eating dinosaurs??

[Mykasan]

we were not lied to. that's what the information that spread at that time, and was available. Science is always improving.

Speaking of, Megalodon never lived with dinosaurs. The largest shark I know that lived in the Late Cretaceous Period was the 15-foot Ginsu Shark

The title of this video really irks me. I understand it’s dramatic for clickablity, but we weren’t LIED to. We were taught humanity’s best understanding based on the information we had at the time. Then, the information available to us grew, so our understandings changed, cause that’s how science works. It just takes a little while for new understandings to become mainstream as more people learn about the new information. Which is the point of this video, and that’s great, the title just irrationally annoys me.

We gotta appreciate the time traveler who took the time and dedication to film this video

Dinosaurs may have sounded more like birds? Lol just imagine sitting in the countryside listening to the soothing sounds of a t-rex singing in the early morning sun xD

It's also important to note that even if we found perfectly preserved Dinosaur DNA frozen within amber like they do in the Jurassic park movies - the actual half-life of animal DNA is only something like 500 years before it completely breaks down.

So if you were to bring dinosaurs back today, you would either need to somehow completely recreate most (if not all) of their genetic code from scratch, or fill in a lot of the missing blanks with DNA from other similar creatures.

But even then, they wouldn't really be dinosaurs…

They’d effectively just be a weird chimera/mish-mash of other animals, or an entirely new species altogether.

We make dinosaurs look so much like their skeletons. But animals don’t necessarily look like their skeletons. We don’t. Especially not in the face

[gushernandez]

Now I want a movie about dinosaurs that sound like little birds, eagles, and crows.

[DanBrown]

NO LIES. The scientific community is always researching and improving our knowledge of the past as new information and techniques present themselves. Not to be confused with the public's scientific illiteracy, believing things like 'man evolved from monkeys' or 'most scientists thought the earth was flat', which science never said but people still think.

Fun fact:
A T-Rex s closer to us in time than to a stegosaurus. Let that sink in for a sec.

[kenc]

Looking at the brontosaurus, I can't help but wonder how long it takes for food to travel down its neck, let alone digest, given that they are herbivores, and those plant fibers have a tendency of getting stuck somewhere if not flushed down.

As a 5 year old dinosaur enthusianst my mind was boggling these questions. I asked my mom "How could they know which color the dinosaurs were?" I did never get any answers from anyone back then, but now I finally got redemption

[esselsid]

T-Rex with a Mohawk??!!

You son of a gun, I'm in!

It's amazing how many of these things I wondered about even as a teenager, and it took scientists this long to figure out and start discussing them officially. I used to wonder how they knew dinosaurs weren't warm-blooded, and how they knew all of them laid eggs. I used to wonder where the space was for muscles when they showed the bones next to an overlay of the creature with skin, and why none of them had fat or neck skin flaps like birds or lizards. I used to wonder how they knew they had all skin as opposed to something like fur (though, it turned out to be feathers).

It was all of those things they shame you for wondering in school because it goes against the modern perception (a very "stay in the box" way to exploration, I suppose)--only to roll your eyes when they start coming up with those ideas themselves... Not sure if my teenage self would be excited or annoyed by scientists finally discussing it more.😑

Crocodiles are not dinosaurs
To be a dinosaur you have to have a few qualifications
1 You Have to be an archosaurs which eliminates everything except for crocodilians and pterosaurs
2 You have to be part of the Avemetatarsilia which eliminates crocs
3 In retrospect is that you have to be member of the dinosauria

[brandoncruise]

There’s a minor correction with the Jurassic Park movie and novel. In both, the main character believed originally that T-Rex had poor eyesight, but learns that that is wrong.

Me 65 million years after : these dinosaurs wings taste good 😅
