The Return of Giant Skin-Shell Sea Turtles

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.

    Thank you all so much for making this program. I went to parochial school so my education did not have anything about evolution whatsoever. I get to learn and catch up with the rest of the population!

    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?

    @John Thumble ok .. late Ordovician, 85% of all animals are eliminated ... 66 million years and a second extinction , of the 15% that survived the first this time 75% are eliminated, 349 million years later it is eliminated 95% again of all the animals on the planet, ... 50 million years and of that only 5% survived in Permian, 80% in the Jurassic disappeared... another extinction and another extinction ... can you tell me if the animals had accelerated growth in evolution ... because you are playing with several extinctions starting from the first one that only left 15% ...

    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?

    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.
