An Illustrated History of Dinosaurs



Our image of dinosaurs has been constantly changing since naturalists started studying them about 350 years ago. Taken together, these pictures can tell us a whole lot about just how much we have learned. Let’s explore the history of dinosaur science as seen through the history of dinosaur art.

Special thanks to these paleoartists for allowing us to use their work in this video:

    I was that kid in Sunday School at that would always ask the teacher, "But what about the dinosaurs?!?"

    I am sure we will find dinosaurs in other planets if we can travel great distances out there in the Universe.

    Check out this amazing dino-art done by the swedish artist Simon Stålenhag. He worked with the scientists at the Swedish Museeum of Natural History to draw theese pictures for an exhibition about dinos at the museeum.

    11:40 "as long as dinosaurs remain extinct" sounds like someone was been watching a little too much Jurassic Park 😉

    pardon me but since the scientific term dinosaur first appeared in 1840, and the science of paleontology began to be formed in 1790' earlier attempts at figuring out fossils do not nessecarily count as studies of dinosaurs, since nobody knew what they were

    My uncle discovered the bone of the smallest dinosaur ever… then kept it in his drawer for years -_-

    wtf Hank? what are you doing here?? not that i didnt like the presentation but you know….

    The evolution of dinosaur art is a lie! It's simply artistic adaptation.

  16. Mark DeRidder

    November 7, 2017 at 10:12 pm

    Awesome video! But I feel Jurassic Park should be highlighted for its transformative power on the general public's perception of how dinosaurs looked and moved. Before 1993 I remember thinking t-rex walked upright. The more bird-like postures and movements in JP really made those dinos feel fresh and real to audiences.

    My friend tried to argue with me that non avian dinosaurs never existed because the Bible never mentioned them………… poor brain washed creationist ('_')

    I…love…this…channel. Avian-Dinosaurs are the only dinos that we can at least see.

    when did we realize that dinosaurs were extinct by one big event rather than they being bad at existing gradually

  24. Mario De Martino

    November 11, 2017 at 7:05 pm

    Could you do a video about the speed of dinosaur? Like, how fast did most species of every family moved, what was their stamina ecc. Please i would love you too

    Owen always is credited as commissioning the statues, but he was 2nd choice to Mantell, who declined the offer to advise the sculptures due to his poor health. Owen, although brilliant, was a con man and a ruthless ass.

    In some parallel reality, the things are swapped, and we have all the dinos, trilobites, old mammals, while the pigeon is something like a T-rex in popularity.

    Really cool series so far. How about doing an episode on the history of fish? They've been here forever and everyone sees them as lesser animals.

    There will always be a little part of them that well just have to imagine for ourselves.

    C'mon PBS, the history of the history of something is called Historiography, don't tell me yr gonna tell me the history of the history of studying dinosaurs. That's the historiography of studying dinosaurs.

    The last sentence in the video sums up what we all have in common, imagination.
    Imagination is why most of us are here, when i think about a dinosaur, i see feathers, leathery skin and scales, heck i even see dinosaurs with polka dots because a teacher once said "they could have polks dots." Dinosaurs are a part of our mythology that we can see, study and find in the dirt below us, the very dirt everything we know and love came from.

How big is our planet? – (self experiment) | Breakthrough Junior Challenge 2018




Is our planet infinitely big? NO, CERTAINLY! Then how big is it ?

Today satellites have enlightened us to get the exact picture of our earth. But 2200 year ago a man called Eratosthenes could find the Circumference of the entire earth using just SHADOW and HIGH SCHOOL MATHEMATICS with an error of less than 1%!!

And yes you can find the circumference of the Earth yourself !!!

Watch the video to learn more.

This is my first attempt in the Breakthrough Junior Challenge.

Please leave a comment if you want to ask any question. Any sort of advice is solely appreciated.

Like and Share if your brain was pleased with the video!!!

Thank you so much for watching!

I wish luck to all the fellow participant out there.

Who is Eratosthenes?
Eratosthenes was a mathematician and the chief librarian of the historic library in Alexandria. Eratosthenes was also termed as Beta, the second Greek letter as he was second best in everything after Archimedes. He developed a way to find prime numbers known as the Sieve of Eratosthenes. Find more of it on the internet.

Have you ever wondered where you live and what is hidden in the blackness of the cosmos? Is there any end or is it infinite? Where is the center of the universe? …or is there no center?
I am sure at least once you were thinking about it. In this video I will try to answer these questions.
