Ok so when I was little(~2008-12) my parents would let me watch these downloaded shows on the Ipad. Specifically I remember one dinosaur documentary that I watched a lot. It might have been a collection of episodes or a couple isolated documentaries made by the same people, not fully sure.
Basically it would teach kids about dinosaurs in a very Edu-tainment style. The host/narrator was a little planet earth(he might have had a mild southern accent). It used a bunch of clips from old movies with dinosaurs, stuff like The Lost World(1925) and other stop motion dinosaurs. Specifically I remember it using a lot from The Lost World, stuff like the T. Rex fighting a triceratops and then brontosaurus. Because of all the old movie clips, I think the framing sequence was in a movie theater.
It was very much an introductory video to my memory. Like it wasn't going to deep and mostly introducing kids to the concept of dinosaurs, their history, and the basics, not really focusing in on one topic of dinosaurs but a generalized overview.
This couldn't have come out any later than 2013, because I remember having already stopped watching and mostly forgotten about it by the time I got to 3rd grade.
Not sure if anyone else remembers this but thought I'd throw out my line into the void and see if anyone might know what I'm remembering? Thank you for any help you can offer.
EDIT: FOUND It was National Geographic's Really Wild Animals
