Aries Design: Truly Aries, or actually based on Capricorn?

We can discuss the exact species of course, but given the huge skill level variety of these artists, paired with the general overlap between rams and goats, i'm not certain we can count on these animals being drawn as anatomically correct.

It seems this "eating a tree on a rocky slope" depiction (tradition? depiction? I need a word for "the setting / the scene / the idea / the concept") also transcends whether or not it is even a goat at all. Here is one i've literally just come across as I add the sequence from this MSS:

So I think there has to be a distinction here between the concept of what is being depicted, and which species of animal it is. This is clearly the same scene as many of the examples in the OP, but it's a sea-goat, and the goat half is also drawn quite differently, especially the horns.
