Chased by Dinosaurs

[Amtoine Grant <ajgrant@eastlink.ca>]

Is on right now, so it'll probably be on again later. But I have a  
question about this series. Are there more than one version of this?  
Because I have seen clips that apparently are from this feature, but  
nowhere in it do you actually see it. And I've watched it like 5 times  
so far.
One is on the top-front of the Chased by Dinosaurs box. It shows a  
mosasaur breaching the water to grab a pterosaur in the air. This also  
on Frametore's website  
(http://www.framestore-cfc.com/television/index.html)
Another depicts a Sarcosuchus grabbing an iguanodont in the water  
(http://www.framestore-cfc.com/television/wwd_specials/claw_giant/ 
index.html) and the other
The last, from that same page, depicts an allosaurid vs an iguanodont.

Are these cutting room floor clips, deleted sceners, or just stills?
