Another documentary would have just said "Here is the oldest fossil known on Earth, and how it was found, etc.". This channel makes a tale of its subjects. A story spanning eons upon eons. This is what makes it so amazing.

[@thomasolson2806]

True about an unfolding story, but it also puts together the bits and pieces which (for me) were individual discoveries into an evolving "tale".

I'm so glad I found this after I had watched all the PBS Eons episodes! I was taught creationism in school, and i LOVE how much learning about deep time has transformed my understanding of the planet and all life in general. I think it's far more magical to understand that all of this was not magically created in an instant, but that it instead took billions and billions of years of trial and error, innovation, catastrophe, cooperation, and failure to get here.

[@curbroadshow]

You were taught creationism in school? Wow that’s mental. How did they explain dinosaurs?

[@Hallo1248574]

God tries to confuse or test us or somethin. These knuckleheads will find some bollocks explanation that is no explanation at all and when you challenge them on this they just fall back to "God works in mysterious ways" which translates into: we are content in not understanding and having faith in some invisible beard in the sky that everything will be ok. How creationism can be tought in schools, is beyond me. I suppose this is only possible in the US, land of the free, where you can do anything you want even if it's harmful or just straight up stupid.

As a palaeontology nerd, I had to make a couple of corrections. The rocks around Lyme Regis, where Mary Anning did her fossil-hunting, are late Jurassic in age, making them more like 150 million years old rather than 200. Also, it's pronounced 'plesiosaur', not 'pleosaur'. Great video nonetheless!

@Mike Nunyabizness nerd

[@pastlife960]

Tom's Ghost Plesiosaurs have long necks, pliosaurs have short necks. He showed a plesiosaur skeleton, but said pliosaur. My point still stands. If he had shown a pliosaur skeleton and says plesiosaur, then that would’ve been fine, as pliosaurs are a subset of plesiosaurs. But he didn’t. You should also know that neither term refers to a species. Each group had dozens of species in it. I know my stuff, I bloody well should as I am reading Palaeontology at uni atm. There’s no need for any name calling.

3:50 Ichthyosaurs, Plesiosaurs and Mosasaurs are specifically *NOT* Dinosaurs. Additionally, members of the Pterosauria were also not Dinosaurs. The vast majority of Dinosaur Species were terrestrial (land dwellers), and to date, the only Dinosaurs thought to be aquatic were the Spinosaurs. Finally, Avian Dinosaurs (such as Archaeopteryx) did not appear until the late Jurassic, and thus I would not consider them to be "dominant" at this time.

That's why, at around 2:18, he states "ichthyosaurs and pliosaurs, contemporaries of the dinosaurs..."

3:56 Dinosaurs did not conquer air or sea during the Jurassic. Pterosaurs and their airborne relatives were a form of archosaur, as were dinosaurs. But in the seas and oceans, it was other forms of reptiles that dominated: Sauropterygia and ichthyopterygia, two clades which are nested directly under reptiles, not part of any other reptilian lineage. And then in the Cretaceous, you got mosasaurs, which are squamates, close relatives of the extant reptiles, particularly monitor lizards.

Harriet Harlow Sorry to disappoint. Mary Anning's story is truly remarkable but she was by no means the first. Google: Georges Cuvier, for example, or William "Strata" Smith. Smith has a story to match Mary Anning's, and it's well told in "The Map That Changed The World" by Simon Winchester. I own up to having a soft spot for Smith. I grew up in near where he did a lot of his foundational research, during the construction of the Somerset Coal Canal. I recall as a child being shown the memorial plaque on a cottage in Midford and then being told that it was on the wrong cottage! He's one of the reasons I ended up studying geology.

In the 19th C Aristotle’s description of the sex life of the sea urchin was discovered to be correct.
