An OC could be a young dinosaur who is orphaned and is found by Littlefoot's group. This OC has a deep fear of certain predators due to past traumas.

One idea could be Ducky getting separated from the group during a big storm and having to find her way back.

One plot idea could be Bron leading a group of dinosaurs on a journey to find a new watering hole during a drought.

This human could try to study the dinosaurs' behavior and in the process, discovers a way to communicate with them on a deeper level, leading to some heart - warming and adventurous interactions.
One idea could be exploring the relationship between Littlefoot and his mother more deeply. Maybe write a story where he has dreams that give him more insights into her.

A third idea could be to write a fanfiction set in the future of the Land Before Time world, seeing how the characters have grown and how their society has changed.
A plot could revolve around Red Claw having a past connection with one of the main characters' families. For example, he might have known Littlefoot's father and there was an unresolved issue between them. This connection could force Red Claw to re - evaluate his actions towards Littlefoot and his friends, leading to a complex and emotional story arc.
A plot could revolve around a strange weather phenomenon in Paradise Valley. Unusual storms start to occur, and the dinosaurs have to figure out what's causing it.
