In general, were animals anatomically correct in ancient representations in art? [possibly NSFW]?

Did ancient artists tend to censor the genitals from representations of animals (even people)? What about objects believed to be for children like carved statues/dolls? Any cultures from ancient times would be interesting to hear about.

It was mentioned in another thread how weird it would be for Winnie-the-Pooh to have genitals. I agree, but it’s also weird that we more-or-less “edit” every animal to remove their reproductive organs. I’m wondering if this is a new thing or if it was being done in ancient cultures?
