One of the highlights of going to a natural history museum is seeing the ancient, the

extinct, the giant -- animals like dinosaurs are huge attractions, but the thing is…

程度の副詞

what you can see isn't entirely accurate… the color's all wrong.

Some of the first dinosaur fossils were discovered in the 17th century.

The discoverer thought it was part of a giant human!

It wasn't for nearly two centuries that scientists would realize these bones belonged

not to giants, dragons or pre-flood Biblical creatures, but to multi-million-year-old dinosaurs.

Immediately, scientists started trying to gather and arrange bones and fragments into

shapes and species -- many of which they (very famously) got wrong.

Putting bones together, and knowing what a dinosaur looks like is a big leap.

Imagine for a second you have never seen a living human, no one has.

You don't know much about this animal, or what it looked like on the outside.

What does its skin look like, does it have scales?

Someone who looks into this, would be a PaleoArtist.

These artists recreate extinct animals and plants, and they're they ones who decided

In the 19th century, paleoartists took dinosaur bones; and they used contemporary giants like

elephants and rhinos as well as reptiles to inspire their idea of what animals would have

This is how we got massive, tail-dragging animals plodding hither and thither.

Over time, scientists debated the finer points of these animals.

Like, whether the head was held up above the body -- like a giraffe, or at body level.

How would these bones move if they had muscles… and the drawings evolved...

By the 1960s and 70s, dinosaurs had trimmed up, they were looking lighter and fitter -- and

We've found fossilized skin, and it can tell us the texture, look, and feel of a dinosaur,

Fossilization turns dino hyde to stone -- meaning no melanin, no melanosomes, no color.

In 2013 a Canadian scanning company took a textured bit of skin and bounced infrared

wavelengths off of it hoping to reveal the fossilized melanosomes -- the bits of skin

They based this on earlier studies that tried to see if fossilized melanosome shapes could

They've used this method successfully with well-preserved feathers, which dinosaurs were

And FEATHERS could have had numerous colors, just like the birds dinosaurs evolved into.

Though it's maddening -- scientists are still in the dark on this.

The “most accurate depiction” of a dinosaur (as it was billed) makes the tiny Psittacosaurus

look cute, and… brown -- which they found by lasers scanning the melanosomes in the

And, as long as we're copying birds, coloring is often sex specific.

That said the shading camouflage makes this one of the most accurate dinosaur depictions

Ultimately, and for much of our depictive history of these animals, we've sort of

been… 'winging it' using data that's available at the time!

In May 2017, a beautifully preserved fossilized nodosaur was revealed… found in a Canadian

They scanned the skin and found the presence of reddish pigments!

This dinosaur is gorgeous, we got the hook up on pics Royal Tyrrell Museum in Canada.

But, they scanned the skin and found the presence of reddish pigments!

In the end, the dinosaurs in your imagination was seeded by the imagination of paleoartists.

Their work is what created dinosaurs in movies, museums and theme parks.

They fill in the skin on top of the skeletons, creating this rich tapestry of ancient life…
