Eli5: how do scientists “know” the behavior of dinosaurs without actually observing them?
In: Biology
There is some guesswork, but they can compare the bones to living animals (things like what shape the teeth are), they can look at bone thickness to work out how they moved, injuries to work out if they fought or which species preyed on which, sometimes dinosaurs even die in the middle of fighting so we can learn a lot about how they attack it defend themselves etc.
