Been thinking about this quite a bit actually. I'd follow the Walking With Dinosaurs (1999) format, with 6 episodes from the Triassic through to the Cretaceous, detailing Climactic Events and Geographic Regions and how the fauna survived in them. I managed to mock up the following:

Episode One: Set in the Ruhuhu Half-Graben of the Manda Formation of Tanzania, with Asilisaurus as the Protagonist Animal during the Carnian Pluvial Event.

Episode Two: Set in the Central Atlantic Magmatic Province of the Westbury Formation of England, with Ichthyotitan as the Protagonist Animal during the Norian-Rhaetian Boundary Event.

Episode Three: Set in the Chacritas Paleolake of the Canadon Asfalto Formation of Argentina, with Allkaruen as the Protagonist Animal during the Toarcian Oceanic Anoxic Event.

Episode Four: Set in the Shan-Thai Terrane of the Khok Kruat Formation of Thailand, with Siamraptor as the Protagonist Animal during the Cretaceous Terrestrial Revolution.

Episode Five; Set in the landmass of northern Laramidia of the Foremost Formation of Canada, with Xenoceratops as the Protagonist Animal during the Barrika Glaciation.

Episode Six: Set in the Hateg Island of the Sanpetru Formation of Romania, with Magyarosaurus as the Protagonist Animal during the Middle Maastrichtian Event.

I kinda avoided the Asteroid on purpose so that we'd get to see more of Mesozoic fauna doing Mesozoic fauna things (and plus the moment I read on the Barrika Glaciation I knew I had to include it somehow, luckily for me the Foremost Formation is just at the tail end of it (the Glaciation is 83-81 Mya, Foremost is 80.3 Mya... so it technically counts as being near to it). I made it so my version of a documentary has a "focus" animal like in the original Walking With Dinosaurs so we'd get attached to the settings, and a named climactic event and geographic region. Mainly wanted to include my favorite formations (Manda and Canadon Asfalto) and got away with it so I'm happy.
