The first Land Before Time sequel to be released on DVD consecutively with its VHS release.
This is one of the few Land Before Time films where the main group is not in danger of being eaten at any point during the movie. The only Sharpteeth that appear are flashbacks, and though the Sierra threatens to feed the gang to Sharpteeth at some point, no dinosaur is expressly interested in eating another dinosaur.
Pterano has become extremely popular among fans, featuring prominently in fanworks and cited by many fans as their favourite character outside of the five main characters, or their favorite new character. Many fans claim that his voice-actor is what makes him such an appealing character, being one of the few new characters to be voiced by an actor other than a voice-actor. His voice-acting has even been compared to that of Tim Curry, due to their similar overacting and English accents.
Michael York received a Video Premiere Award nomination for Best Animated Character Performance in 2001, for voicing Pterano. The nomination was shared with supervising animator Zeon Davush.
Rinkus and Sierra both play a similar role to Ozzy and Strut in The Great Valley Adventure, Rinkus being voiced by Rob Paulsen, like Strut except more cruel. Also it is left unknown whether either pair survived at the end.
This was the first in the series to use digital ink and paint and computer techniques for the animation rather than transferring the characters to cels (I-VI). However, the animation design for this film is entirely different than the animation design for the following films from The Land Before Time VIII: The Big Freeze onward.
The original title for the movie could have been "Search for the Stone of Cold Fire" as the trailer narrator calls it in this trailer.
This was the first sequel in The Land Before Time film franchise to be released on DVD.
This is the second film not to have a narrator. Instead, Petrie narrates the opening scene.
There is a scene when Littlefoot, Cera, Petrie, and Spike are crossing a canyon on vines, and Cera complains that every time they do this she is always at the back of the line. However, Spike is almost always the one at the back of the line, not counting Petrie, who flies across, with one exception in The Land Before Time VI: The Secret of Saurus Rock, when they are quickly crossing a log while being chased by a Sharptooth. However, during this scene Cera is the first to cross and Littlefoot is the last.
The music that plays in the background when the gang is chasing the male Rainbow Face is the instrumental music from An American Tail: The Mystery of the Night Monster.
This is the first film in which Petrie cries, although he may have cried in the original, however, his face is turned away from the camera in that movie. In this film, he cries four times. First film in which Spike cries. There are tears visible in his eyes during the scene where he draws in the dirt.
Rainbow Faces later appear in The Land Before Time X: The Great Longneck Migration running along with an Ouranosaurus and a Styracosaurus.
The music from this film was also played in the first episode of the Jimmy Neutron spin-off show, Planet Sheen, when Sheen was on his encounter with Bobb, due to Michael Tavera composing the music for the show.
This is the first, and so far, only film with leaf eater villains who are truly bad. (Hyp, Nod, and Mutt later reformed as did Pterano in this movie though Rinkus and Sierra, if they survived, are still evil. Strut is technically an Egg Stealer, even if he does eat plants for whatever odd reason.)
It is heavily implied that the two Rainbow Faces are extraterrestrial beings that took on dinosaur form to educate those in the Great Valley. Their vast knowledge of the outside world, manner of speech, and the male Rainbow Face's occasional close calls of revealing too much information indicate this.
