Amazon only has episodes 1 through 6. I've purchased and watched them already, and I"M DYING to watch the final 2 hour special. Discovery channel said it was aired on May 23rd.
It's called Jurassic-Sized Prehistoric Terror. Not to be confused with the 3rd episode of the season titled Prehistoric terror.
I've googled the hell out of it, and can't find any credible links.
help Help HAAAALAHAAALAAAAELP!!!
