Although it says "Volume 1" on the box, Amazon.com describes this set as "The Complete Series 1 & 2." Technically, it's accurate: while BBC America aired them all in a row, this is actually the first two British series, a grand total of 13 episodes, each of them full of ferocious, dino-tastic action. But the word "complete" only applies as far as Series 1 & 2 are concerned, because Series 3 starts in January. The episodes are worth the price of the set alone, but luckily there are a few extras to sweeten the pot.
