What if dinosaurs have survived the asteroid impact? Could we have seen a shared dino-mammal ecology, or even intelligent dinosaurs?

  • Last winter I visited the Dinosaur Resource Center in Colorado. They told me how most dinosaur species have only ever been identified by their teeth (usually the hardest bones in any animal.) A lot of the skeletons we saw on display were the result of 3D scanning what bones we COULD find to extrapolate the shapes of those missing (i.e. mirroring the left arm to make the right.) Most of their exhibits are at least partially 3D printed, and they sometimes color-code the filament so visitors can identify which pieces weren't unearthed naturally.

    My cat usually pays zero attention to the TV, but he watched this video with rapt attention for a solid 20 minutes. Lol

    Harry Harrison wrote an interesting sci-fi series called the "Eden Trilogy" that explores the scenario of the K-T meteor never hitting, and a dinosaur species achieving sentience and advanced technology through chemistry and biology rather than mechanical or electrical. And they have to deal with isolated humans who have only made it to the hunter-gather stage. It is a well thought out "what if" alternate history :)

    There's this short story: aliens make a stop on moon for minor repairs and in free time zoologists visit Earth where they witness fight between dinosaur and humanoid. They kill dinosaur, spread anti-dinosaur virus and leave. But it was dinosaurs shooting movie about evil humanoids
  • @stoop25
    They had over 100 million years to get their shit together. They missed their chance.

    If you look at birds, larger doesn't always mean more intelligent. If you make a crow bigger, it doesn't automatically become more intelligent. An emu or a nandu is about as tall as we are, and while there's some intelligence in there, they are easily outwitted by crows.

    Thank you for all the work you and the team do on videos; i watch them to fall asleep... then three videos later am still awake. I appreciate the thought-provoking entertainment.
  • @0cujo0
    They had a documentary about this - It was called the Flintstones

    The idea that dinosaurs had less advanced thermoregulation than modern mammals is looking increasingly less likely. Numerous dinosaur fossils have been discovered in areas that would have been very close to the poles, which even with the warmer climate would imply the ability to survive extremely harsh winters. Additionally, like birds, dinosaur physiology might have even presented advantages in terms of thermoregulation. Air sacs and pneumaticized bones enable birds to have much greater respiratory capacity than mammals, and appear to have been common even in large dinosaurs, like titanosaurs.
  • The primary reasons no (therapod) dinosaur could have evolved a humanoid body are that they were already bipedal, their shoulders were not adapted for climbing or swinging, and they could not pronate their wrists (required for climbing without claws).

    As a geologist that likes to S-Post I need to say that this was when flowering plants first started to flourish. I think the dinosaurs all sneezed to death from hay fever.
  • T-Rex moon landing would be like: “One big step for a t-Rex, and, uh, a bigger leap for t-Rex kind.”
  • @joshuaperry4112
    How to you console a hungry T Rex? A-pat-asaurus on their back and There-Therapod.

    What do you call a dinosaur accident? Not covered by my insurance.
  • @JamieAlice92
    What do you call a dinosaur that lifts? Tyrannosaurus Pecs.
  • I think it would have been much easier to hack computers if the dinosaurs hadn’t gone extinct. There is no way a Tyrannosaurus rex would have a complicated password with those arms.
