I don't know if this has been mentioned before or linked to but if you go on YouTube and type Pictures from The Land Before Time and find the one by LBTUploader you will find pictures from the Collector's Edition LaserDisc version of the film. I took note of some scenes not in the DVD or newer copies of the VHS.
00:29: Pic of Cera's sisters. Not sure what the scene was about.
01:47: A pic of the Sharptooth that I did not see in the DVD. (do not have my 1988 VHS version

.....)
02:28: I didn't see this scene in the DVD version either. I wouldn't begin to know what this scene was.
4:39-4:45: The Spike Scene where Ducky wants Spike to join the herd. The second still is of Ducky with the berries.
4:49: Explains to me how they manage to get to the hole showing the circle of trees in the cave. The extended climb down the cave scene.
5:33: I've seen this still on this thread once before. Not on DVD.
5:50: A closeup scene of the gang sleeping in the Sharptooth footprint. Not on the DVD.
6:23: When the gang slides down the hill, there is an extended scene.
9:18: I've seen this still on this thread, also. It is the scene from the original where Littlefoot finds the Great Vally before rescuing his friends and defeating Sharptooth. Although the pic that follows is of the ending we all know now.
I thought this was interesting. I've seen people on Ebay selling the Collector's Edition of this. If anyone was willing to pay for a player and the disc. A cheap player can be found on Amazon. And you can just search for the disc on Ebay. I would love to see these scenes. I wonder if the Mother vs. Sharptooth scenes (extended) are on there, too.
