It’s a matter of available data. If you want to tell the difference between two skeletons, there are not many features to compare.

Now if you compare two living organisms, you can see the color, you can see its behaviors, you can see what it eats, and you can see if they can breed with one another.

Fossilized skeletons tell a story, but the story is very incomplete.
