On that note, Deserts then moves to eastern Asia where we meet iguanian lizards (many quite similar to the agamas and others of today), the tyrannosaurid Tarbosaurus and others... Prehistoric Planet

 

Azhdarchid Pterosaurs soar overhead. Fossils confirm that azhdarchids did occur in Late Cretaceous Asia, and in desert settings. Note that our azhdarchids have the 'forward-swept' wing configuration they likely used at times.

 

Our Tarbosaurus is shown with filaments in addition to a mostly scaly covering. Whether tyrannosaurids did have filaments is controversial among experts, but some recent studies conclude that filaments may indeed have been present along the dorsal midline at least.

All I'll say at this point is that the scientific discussion isn't over, and that the presence of both scales and filaments should be considered very much possible. Perhaps the main star of the episode is our fully feathered, 'ground hawk' Velociraptor.

Excellent evidence - including complete skeletons from China and quill knobs on the forelimb bones of Velociraptor [photo M. Ellison/AMNH] - confirms that these animals were fully feathered, as much as birds are today. This is not in the least controversial...

 

We do not portray Velociraptor as a 'pack hunter', but as a more opportunistic, partly social animal that might have moved about in twos or threes on occasion. Support for this comes from dromaeosaur trackways and the behaviour of modern predatory birds...

 

The facial tissues (leathery skin around the jaw edges with some keratinisation here and there), look of the scaly feet and giant sickle-claw and pattern of the plumage involved SO much work by so many on the #PrehistoricPlanet team! There's too much to talk about! Also..

 

Some ppl have drawn attention to the fact that the best known Velociraptor species are too old to appear in a documentary set in the Maastrichtian. However, fossils of 'indeterminate velociraptorines' are known from several Maastrichtian east Asian assemblages, some of which..

 

..might turn out to be additional species of Velociraptor. We simply couldn't say "this is an indeterminate velociraptorine" in a documentary, so I hope you all understand the necessary shorthand!!
