I think, the main weakness of any flightless bird is the protection of its eggs. The endurance and efficiency when hunting should have exceeded mammalian hunters. But medium-sized mammalian carnivores may have feasted on the eggs reducing the reproduction rate below 1.

It still astonishes me that we know so much about these ancient creatures. Obviously our knowledge is a tiny sliver of what likely existed! But even knowing how much we DON'T know is mind-boggling. I am curious as to how one would know if a baby dinosaur "changed stance," though? Is it a change in the bone structure, or some kind of microfracture pattern detectable in adult bones? (I barely know enough to even ask this, I'm just curious what the reasoning might be)

Im surprised the small ones look so birdlike, or at least what early birds looked like since they both took the generalist Avemetatarsalian bodyplan. If we do end up disreguarding the whole point of Jurassic park and make non avian looking dinosaurs then we can at least make some early sauropods too.

I understand your desire to not cover dinosaurs since so many other channels do. That being said, I haven't seen many people cover Avialans (Proto-birds) and the earliest forms of Dinosauria from the Triassic, such as coelophysoids, Sauropodomorphs or Herrerasaurs. In fact, the basal members of even later dinosaur groups are not covered much, despite showcasing fascinating anatomical, behavioral or dietary traits essential for later evolution. Besides all this, I would love for you to cover early forms of life, Paleozoic or even Pre-cambrian! Those ages (besides the Permian a bit) don't get nearly as much attention!

Great video as always. Personally I think you should do more videos covering non-avian dinosaurs because while yes they do get a lot of coverage, that coverage is always isolated. Like yes they are talked about but only singly pertaining to the specific animal whilst also ignoring their phylogeny favor of a more “gamey” “smash bros” like character profile. Not that there isn’t a place for that but it often takes away from the real complex evolutionary history these animals had just so they can talk about how cool this specific animal is.

The depiction at 5:11 is adorable. It's probably an awful pet, but I want one. I guess sauropodomorph is what you call these animals now, because they were called "prosauropods" for most of my life. Speaking of outdated ideas, it's funny you mentioned therizinosaurs since I had books back in the day that said therizinosaurs were "prosauropod" relatives. Early therizinosaurs and sauropodomorphs do look somewhat similar, but even when I was 12 that didn't sound right to me.

Given that the early Triassic was populated with such a diverse range of animals, its a wonder that dinosaurs eventually became dominant. Had things worked out just a little differently, we might not be marvelling at birds, but instead be debating the land-croc problem!

@@JohnyG29 I think so, the only other channels that dose evolutionary history or phylogeny is Anthony Pain and animals origins. The latter does more modern animals and Anthony Pain dose cover non-avian dinosaurs but there video are 4 years old, EDGE has Tyrant Files but that’s also 4 years old at this point the only exception is paleo nerd that has one video of Dromaeosaurs that’s a year old but most of their videos on the topic is also 3-4 years old. ben g thomas has some videos on dinosaurs “phylogeny” but most are old the more recent one was (The Mystery of the Megaraptors) but it’s more of a overall history of the group, there’s only 2 cover non-avian dinosaurs. Most videos about dinosaurs are covering new discoveries or species profiles, rather than phylogeny where it’s sometimes briefly mentioned. Both marine reptiles & Pterosaurs get even more over looked in this section as well as Paleozoic with their being less and even more older videos. I feel like this topic is often overlooked in Mesozoic & Paleozoic communities. Unless there’s a channel I haven’t seen then I that case please share
