I just realized that the dinosaurs in The Land Before Time do not really resemble actual dinosaurs. First of all, the various species shown in the series never lived together in real life, neither geographically nor temporally. For example, the length of time separating Stegosaurus from Triceratops is actually longer than the length of time separating Triceratops from modern humans. So showing a Stegosaurus with a Triceratops is even more inaccurate than showing a human with a Triceratops.

They are also anatomically inaccurate. For example, the tyrannosaurs are shown standing with their tail resting on the ground, like a kangaroo. This posture is now known to be inaccurate.
Therefore, taking into account the anatomical and anachronistic inaccuracies, I have come up with a theory that The Land Before Time is set millions of years in the future, and the various "dinosaurs" are not really dinosaurs, but are in fact lizards. Let me explain why.

It has been said that global warming might make reptiles larger and more dominant. My theory is that, in the world of TLBT, global warming causes most of the mammals, including humans, to become extinct. After humans become extinct, the lizards take over as the dominant group of animals on Earth. Millions of years later, they evolve to look like dinosaurs. They also evolve the ability to communicate, like humans. What does everyone think about my theory?

Hello! I joined this forum about 3 years ago, but I never got around to posting until now. I joined because I used to love these movies when I was younger, and I like dinosaurs & paleontology. So I decided to join.
