** Intelligence isn't the only thing a species needs to use tools, it must also have the ability to use them. Dolphins are some of the smartest animals on the planet but tool use is practically (though not entirely) nonexistent because they don't have hands. Also, we don't really know if the humans are less advanced than the dinosaurs. Spot was orphaned at a young age so his animal-like behavior can probably be attributed to that. Chances are, the human family are little different from modern humans, they're just not in an advanced era.

* So from a story-telling perspective, what was the reason for the possible foot shortage? Did that really come into play after it was introduced? It's not like it added a ticking clock element the way [[WesternAnimation/ToyStory Andy moving away]] does, nor was it motivation for Arlo to get home.

* Why do Spot and the other humans wear clothes? The obvious reason is that you can't show human nudity in a kids' movie even if the humans act like animals, but in universe, it's harder to justify. Spot's garment seems to be made out of leaves, which would have to be tied or glued together somehow. Possible, but not likely considering humans in this world are supposed to be the equivalent of rodents. The family of humans, on the other hand, are wearing fur, which would imply they have tools to skin animals. But the dinosaurs, who are supposed to be the most advanced species on earth, don't even have tools.

** I thought it was to make Arlo's dad's very strong reaction to the critter eating their food justified. He couldn't let it go on; it was important so they wouldn't starve. Hence chasing after it and getting stuck in the flood and causing the dad's death.

** I'm guessing its the same reason humans and everything else that currently extant isn't sapient. They're 'new' so to speak.

* Why is it that birds are the only dinosaurs that cannot speak or show sapience?

* Why is it that birds are the only dinosaurs that cannot speak or show sentience?

* Why is it that birds are the only dinosaurs that cannot speak or achieved sentience?

** Spot became an orphan early, he propably saw some wolves and took their habits. [[spoiler: The other humans were just mimicing his actions so that he could think he's one of them.]]
* Why did Spot and Arlo hallucinate due to the fermented fruit if there's no way for humans to hallucinate after eating fermented fruit? Also, does hallucinating actually happen when you're drunk?

* Why does Spot [[spoiler:(and the caveman family at the end)]] howl like a wolf? Wouldn't it make more sense to behave more like the apes humans are closely related to?

** [[spoiler: If I remember correctly, Thunderclap wasn't so much as flying, but weakly flapping around. Even without the flood, he wouldn't have made it far.]]

* [[spoiler: Could it be that the pterodactyls survived? They could swim a bit faster than the flood, and could fly off the waterfall. Even Thunderclap could fly with a hole in his wing.]]

** SquareCubeLaw. Henry's large size meant he was much less likely to survive a natural disaster. See the fridge page for more details.

* A wave kills Henry, so how can Arlo, an 11-year-old with no experience in the wild on his own, survive not only a wave exactly the same as the first one, but ''also'' go over a waterfall with his life intact??

** It could've been carved by a dinosaur species with working hands, like a large theropod or iguanodont.

* How did the dinosaurs make that yoke Arlo's mom was carrying buckets upon? And if they are capable of making such tools, why do they need to plow with their heads?

** That or they're for the eggs.

** Because [[FridgeBrilliance they trade with carnivorous dinosaurs]] to help them get things built for their farm? See WMG.

* Why does Arlo's family have chickens? They're not carnivores.
