So it is. Looking good too.
Highlights in the trailer: maniraptors with proper plumage! A Spinosaurus with a suitable head*! It's a little hard to critique the finer details when they're flashing past in a trailer montage (and yes, the use of the word 'pterodactyl' and a stock raptor sound effect is very lame), but it's looking like an improvement over many CG docus from the last decade or so. Here's hoping!
*Or not quite, as I've just seen these stills, which show that the mandible is a little off (not to mention certain other aspects of the anatomy, notably the forelimbs). Could be worse...I'm still happy about the feathered dinosaurs.
