The biggest turtle ever described wasn’t an ancestor of today’s leatherback turtles or any other living sea turtles. But it looks like there are some things about being a giant, skin-shelled sea turtle that just work, no matter where, or when, you lived.
Thanks to Ceri Thomas (nixillustration.com/), Nobu Tamura (spinops.blogspot.com/), and Dmitry Bogdanov for allowing us to use their excellent paleoart in this video!

So are their shells all made up of skin like an armadillo and unconnected to their bones like other turtles?

How about an episode as to why some animals seemingly do not evolve and have keep their same form over tens of millions of years i.e. ceolacanths, crocs. Or maybe just an episode on ceolacanths in general

I watched a documentary a few years ago and one thing has bothered me ever since. It said that the giant dragonflies from the Carbonifous survived into the Triassic. It said they survived the lowered oxygen levels by using their wings to improve the air movement round the spiracules. It failed to say how they got through the big dying because I cant imagine that working so well during that. Can you make a video on them and if they did survive please explain how thanks

So 15% survived the first extinction, of that 15% you have to eliminate 75%, of what you have left, eliminate 95% again, of that rest eliminate 80% again, of that rest eliminate 76% again .... tell me if your evolution math makes sense?

Question: why do they refer to the circular bones as “ossicles” and not “scutes?” An ossicle is just any small bone, so why not be more specific? Are those bones not considered scutes?

Asking again for a closer look at the former "prosauropods" and how we think they're actually related now. Or, perhaps, a rundown on all major prehistoric aquatic reptiles (including whatever Nothosaurus was, or mostly just Nothosaurus).

May be megalodon was specialised to prey on such turtles and giants prehistoric seals. With his food source extinct, so did megalodon.

How about an episode on the extinct Bluebuck antelope? I feel like there aren’t many high quality videos about this extinct species. You could relate it too how we can determine the genetic relationships of extinct animals with living species.

You wonder why there was an explosion of population animals always find a way to survive. Their first shot at this was as you say the late Cretaceous period when smaller turtle expanded to fill the niche left behind when the big ones are gone. It's sort of the way coyotes filled the niche the wolf left,when it was almost eradicated from the lower 48. They have been almost completely wiped out in the eastern US. Everywhere there are coyotes there were once wolves. Same with the sea turtles.
