Those, in fact, were the two movies I was referring to. If one assumes the original movie to not be 'out of order' (i.e., scene 2 doesn't occur before scene 1), then it is correct that Ducky was born before Cera. However, it is known among the gang somehow in LBT 5 that Cera is the oldest. Cera knew it, and Littlefoot knew it (Littlefoot: "But that's you!" Cera: "I know."). How did they know? Who told them this? One can only speculate. I was basing this trivia question on the assumption that Cera's hatching was shown before Ducky's on the original movie, but after watching the first scenes again, I see this is not the case. It could very well be that both hatchings occurred near the same time, and that due to the 'camera' not being able to conveniently show both hatchings at the same time without making it look ugly, one was arbitrarily chosen to be shown before the other. It is on this that I say Cera was born before Ducky, but you may well disagree, so I'm just going to let which ever of you two (Achillobator and Malte279) gets here first post the next question, though I think it would be more fair to let Malte279 do it since Achillobator did a question most recently.
