    Reptiles emerged from the Paleozoic as humble creatures, but in time, they grew to become some of the largest forms of life ever to stomp, swim, and soar across the planet. This Age of Reptiles was a spectacular prehistoric epic, and it all took place in a single era: the Mesozoic.

    This episode (as well as most episodes of Eons) features beautiful paleoart from Studio 252mya. We dare you to try to not spend hours looking at their work:

    And thanks as always to Nobumichi Tamura for allowing us to use his wonderful paleoart:

    Produced in collaboration with PBS Digital Studios:

    Love the show but I could do without seeing the narrator don't think seeing them adds anything to the program.

    in order to follow this, you have to have a clear idea of the periods and why they were defined as such. personally, if there was a vertical scale on screen with the periods marked and the topic era highlighted, i'd have a much clearer understanding. Without it, this video is a rapid and relentless list of Greek and Latin nomenclature, and my lasting impression is that we evolved from a rat. The emphasis here is on the audio, but with some basic graphics and animation, could be visually reinforced and more easily recalled by the viewer.

    During the Age of Reptiles, one hears of flyers, land creatures, and aquatic creatures. What I never hear of is arboreals. What filled the niche held now by squirrels, monkeys, tree snakes, etc.? How did they interact with ground creatures? Thank you.

    Predators regulate populations, keeping them down . This plays an important part in the occurence of species. Their size is relative to the species predated upon. T rex hunted in packs, and as individuals , like hyenas , lions ...but more like lions. Their prey was pretty big. And it was a rare thing for a single t rex to take down something big by itself. And yes they jumped on the back...the reason why they have such strong lower legs. They most likely did like the wolf...because they have a long head, they went for the throat.

    One way to add a type of show: consider doing like a day or a year within one of these large time frames to imagine daily life on earth. Use funny and cute names to allow us to connect to these wild creatures and climes, tell a story with verisimilitude, and then kill off some of the good characters and most all of the bad characters to give us the feels. I want to enter these worlds via the power of imagination and story. Plus, feel the emotions that a tiny rat like thing would have felt, cuz I guess that’s us then.

    The feathered T-Rexes are a little out of date. Several fatherless skin impressions have been described recently.

    Not all of the underwater reptiles/giant prehistoric fish species went extinct either, but that’s a different story located within the study of Cryptozoology.

    The Tyrannosaurids actually existed on the threshold of The Cenozoic Era, or as many of you know it The Ice Age.

    Very interesting but is there any chance that the narrator could speak a bit slower and draw breath between sentences? it would be so much easier to understand.

    The video is great and all but why do you keep referring dinosaurs as lizards are reptiles when they were Birds?

    Pretty sure most of those large terrestrial dinosaurs were dead long before the effects of starvation hit them, They were basically roasted alive on the day of the impact when massive heatwaves swept around the globe.

    Ok, so are birds reptiles, or have have they changed so much that 'reptile' doesn't apply anymore??

    The really interesting part is that some of those early reptiles evolved into mammals before the Great Dying.

    What are the reasons for naming the different era's and sub era's. Geographical? Also what do the different names signify? Strata and location? I would be interested to know even in the more detailed analysis of the finer divisions, as in the example of the Cretaceous, there are many subheadings as demarcation points. Reasons?

    Today I learned that we may ravage the planet as bad as we want, life will always bloom again anyway.
