It’s more than 30 years old.
It’s not HD. It still supports the notion of a inverted hanging pterosaur. It precedes the discovery of eggs. Even so, it features a gliding Pteranodon model, lots of great sea bird scenes (including diving pelicans, soaring, dipping frigate birds and skimming skimmers) along with several great bat scenes (including grounded bats taking off).
And Mr. Attenborough was just starting to get gray hair back then. : )
The video also stars a bipedal animated Dimorphodon following the then recent release of Padian’s early work on that pterosaur.
