I’m definitely showing my age here, but the team who made Walking With Dinosaurs created a while line of “walking with” and, while the CG DEFINITELY did not hold up, the science is still pretty decent.
Walking with Monsters (pre-dinos)
Walking with Dinosaurs
Walking with Beasts (post-dinos)
Walking with Cavemen
The latter, over 100 scientists worked on to try and make it as accurate as possible.
Don’t watch the 'Chased by Sea Monsters" one though… for some reason, they changed up the formula and had a guy pretend he was traveling back in time and doing a Steve Irwin on the marine reptiles. It’s just terrible.
