  • What were the Megaraptor dinosaurs? This mysterious lineage of predatory theropods had massive arms bearing huge claws and rose to prominence towards the end of the age of dinosaurs - but many mysteries still surround them.

    I spend my days with over a hundred geese, mallards, Muscovy, chickens, and Guinea fowl. I constantly imagine theropod behavior based on these types of primarily ground dwelling birds. It’s certainly a gray area scientifically, but it’s wonderful to watch them and wonder how similar their behaviors are to their ancestors.

    • @Dragrath1
      @Dragrath1 Před 9 měsíci +18

      What I find fascinating is that the fowl birds are known from fossils in the late cretaceous and based on genetics might go back as far as 90 million years since the fowl clade including its two extant branches the water fowl and land fowl split off from other avian lineages. These fossils while few in number are remarkably similar to their contemporary forms suggesting that they have stayed relatively the same in terms of ecological niches both before and after the extinction. So chicken like birds and Tyrannosaurs actually overlapped in time which is kind of incredible to think about.

      Nonsense. Tail dynamics change everything. It may look like minor changes when they stick a plunger on a chicken but that's just because you're still seeing a chicken. If they were two completely different animals you would never think to compare the two's motility. The future is autistic, that's why it's hard to predict. Of course you can't bring back dinosaurs, but you can bring back non differentiated sets so that it won't even matter. Animals are a dead end anyway, they can't go anywhere.

    Something I just realized is that raptorians having only one big slashing claw is very logical. One slashing edge is more efficient than multiple ones, allowing to focus entire strength of the animal on a single "point" for deeper strikes.
    Megaraptorians having multiple big claws might either mean that their hunting tactics weren't as focused on inflicting big slashing wounds or they didn't need such comparatively big claws to damage internal tissue of their prey.

      Antarctica on the other hand, most likely had its own Megaraptoran assembled because it was a dispersal route for that clade between Australia and South America.

    I think megaraptors were basically like terrestrial birds of prey: they chased down smaller prey then used their meat hook claws to snatch them up when they got within striking distance. The curvature of the claws seems to support this. I wonder also if some biomechanical study could be done to see if the arms would support being shot out forwards like this

      I agree, seems like with their powerful arms, huge claws but what seem like comparatively kind of weak jaws & teeth that they mostly hunted prey smaller than themselves and just grabbed and ripped them apart. I think the fact that they seem to have had quite long and gracile legs probably means they were pretty solid runners, which might be more support for the idea of them hunting smaller prey animals.

    One correction. Siats meekerorum is from the Early Cretaceous Cedar Mountain Formation more specifically the Mussentuchit Member which is the last member of that geological sequence.

    • @Ozraptor4
      @Ozraptor4 Před 9 měsíci +1

      The Mussentuchit Wash site is dated to 96 to 94 Ma, which puts Siats in the very beginning of the Late Cretaceous (Cenomanian stage). Early-Late Cretaceous boundary is 100.5 Ma.

    Very interesting video about evolution and classification of megaraptoroids especially with them being an early radiation of tyrannosaurids. I have two questions.
    1. How did megaraptors become geographically restricted to South America at the end of the Cretaceous?
    2. Curiously there does not seem be have been any megaraptors found in Africa. Could it be that we have not been looking hard enough? If so, could megaraptors in Africa have undergone a similar radiation as in South America given the late cretaceous extinction of Charcarodontosaurus in Africa like in South America?

    I understand there would be some overlap with regard to what tyrannosaridae and megaraptorans preyed on, but would it be reasonable to assume that their evolution and hunting strategies were developed based on their preferred prey type? i.e it's hard to imagine a megaraptoran dealing with armored herbivores the same way a bone-crushing bite would. If that is true, their decline would be rooted in the decline of their prey items, meaning that tyrannosaurs rose to prominence (and specialization) thanks to an increase in their prey items. Correct me if I'm wrong, of course.

    Maip is My Favorite Member of this group and the most complete Giant megaraptor ever found so far. So I wonder if Africa and other continents even Australia had giant megaraptors in the late Cretaceous era as well that have yet to be discovered, and It just makes me curious just wonder if they'll be even as big as Maip. Maybe even Australia has a group of Megaraptorids that took over as super carnivores in the late Cretaceous who knows right?
