These are all of the cut scenes I could find. I know many of them have been covered before, but I really wanted to make a list of them.
Beggining Longnecks Scene-
One still from the Collectors Edition Laserdisk and another frame show that the scene with the Longnecks at the start of the movie was slightly longer, or at least edited.
Littlefoot Hatching Scene-
One still from the Collectors Edition Laserdisk shows that when Littlefoot hatched and looked at the viewers, the background was slightly different, Littlefoot was farther to the left, it was slightly brighter, more zoomed out, and plants with water dripping off them could be seen behind Littlefoot.
Baby Littlefoot and Cera Scene-
Nothing really known about this scene, except for one frame on an uncolored background, where Cera and Littlefoot are looking at something. They look quite a bit younger than they did in the film. It could be a fake.
Grandpa Longneck Getting Branch Scene-
One still from the Collectors Edition Laserdisk shows that when the screen transitioned to Littlefoot being older, Grandpa Longneck is seen grabbing a branch from a tree, whereas in the cut version he is seen holding it already when the screen transitions.
Cera and Sisters Playing Scene-
One still from the Collectors Edition Laserdisk shows Cera's three sisters playing while one of her parents looks on. Cera is shown running back to her parent and her sisters are shown laughing. Possibly an extended part of Littlefoot meeting Cera, or Cera's birth.
Sharptooth Water Splash Scene-
On an old commercial for the movie, it shows a scene where Littlefoot and Cera are pushed onto Sharptooth's foot by a wave of muddy water. It is supposedly a cut part of the thorn chase scene.
Sharptooth Thorn Chase Scene-
There was most likely a extended chase scene with the thorns and Sharptooth, where he trys to bite Littlefoot and Cera while they ran through the thing they were playing near in the water. A still of it can be seen on the Laserdisk and the book shown above.
Sharptooth Looking For Kids Scene-
One still from the Collectors Edition Laserdisk shows that when Sharptooth first loses Littlefoot and Cera, he can be seen moving his head towards the thorns slightly longer than in the cut version. His eye also slightly opens in this scene.
Sharptooth Falling Scene-
One still from the Collectors Edition Laserdisk shows that when Sharptooth is falling and trying to bite Littlefoot and Cera his whole face is shown, whereas in the cut version only about half of his snout is showing.
Littlefoot Running To Mother Scene-
Two stills from the Collectors Edition Laserdisk shows Littlefoot running to his mother. This is the same as in the cut version except the rain is much more visible, more of it is falling, it is blowing slightly to the left in one scene, and it is a bit lighter.
Spike and Berries Scene-
The gang try to lure spike with berries, Cera doesn't want him to come. The scene was supposedly cut because of Cera being racist.
Waterfall Scene-
I used to think this was a scene from the cut original ending while Littlefoot was running to the great valley, but the waterfall looks exactly like the one near the stream before they found the oasis. The pictures show Littlefoot jumping up the waterfall and looking down from the top, smiling. Littlefoot possibly climbed up the rocks to look off the waterfall for green food.
Oasis Cave Scene-
One still from the Collectors Edition Laserdisk shows the characters climbing down the cave to get to the edge, rather than just appearing there.
Gathering Food Scene-
There was another part to the gathering food scene where Littlefoot, Ducky, Petrie, and Spike were doing things while eating.
Sharptooth Footprint Scene-
One still from the Collectors Edition Laserdisk shows a close-up of the gang after they get comfortable in Sharptooth's footprint. They can be seen in this position zoomed out more in the cut version, but the treestar is not there.
Sharptooth Chase Scene-
One still from the Collectors Edition Laserdisk shows the characters after they went through the small crack in the rock wall to get away from Sharptooth. Rocks are tumbling down and Cera is looking angrily back at Sharptooth. This scene is not in the cut version.
Walking Near Mountains That Burn Scene-
One still from the Collectors Edition Laserdisk shows a close-up of Ducky and Petrie below Littlefoot while they were near the Mountains That Burn. This is in the cut version, but the ash is much less noticeable and the background is slightly different.
“Tar Monster” Scene-
One still from the Collectors Edition Laserdisk shows the “tar monster”. It looks slightly different than in the cut version. The tar is more shiny, and the characters are more easily distinguishable, especially Spike.
Petrie Laughing at Cera Scene-
One still from the Collectors Edition Laserdisk shows that Petrie laughing at Cera went on slightly longer or was modified from the original version.
Cera Slipping on Tar Scene-
One still from the Collectors Edition Laserdisk shows that after Cera slipped on the tar the first time, she looked back at the others angrily. This was not in the cut version.
Going Back to Cera Scene-
A few frames show that they went back to the caves to try to get Cera to come back.
Ducky and Sharptooth Scene-
When Ducky is chased by Sharptooth she makes faces at him and then runs away with a look of terror on her face while Sharptooth leaps at her. Another frame shows a closeup of Sharptooth's face as he supposedly tries to catch her underwater.
Sharptooth “Death” Scene-
When Sharptooth falls into the water, a clear picture of Sharptooth sinking into the water with the rock floating slightly away can be seen. This can also be seen on the cut version, but it is much darker and less clear. The rock can also not be seen.
Petrie Alive Scene-
When Petrie climbs onto the ledge, revealed to be alive, the others (besides Ducky because she is running over to him) look back at him with surprised looks on their faces.
Different Ending Scene-
Supposedly the scene where Littlefoot talks to his dead mother in the cloud and finds the Great Valley was before he went back and saved his friends. This has some proof because when he is talking to his mother, you can see the rock they used to push Sharptooth down is still there in the background. After finding the Great Valley, he goes back to get his friends, and saves them like he did in the cut version. But he tells them he found the Great Valley (at the scene in the lake), and says they have to get rid of Sharptooth so he doesn't go inside the Great Valley. The ending where they look at the Great Valley is also different, as it has a different background, and no mom ghost.
We'll Always Be Together Scene-
At the end when Littlefoot holds up Ducky and Petrie on his head, it zooms up on him and he says “Now we'll always be together!” Then Ducky hugs Petrie.
