Meaning of きれい in this sentence


Regarding a fossil that was dug out of frozen ground in Russia:

> 眠っているように見えるぐらい **きれい** でした。  
>  (The cave lion fossil) was so _neat_ that it seemed like it was sleeping.

I'm struggling to translate きれい in this sentence. Neither clean, neat nor
pretty really seem to make sense. To be honest, I can't think of any English
word that would fit this sentence well. Is there an obvious translation of きれい
that I'm missing, or am I just over thinking it? It is from an article for
children after all.




Maybe trying to paraphrase it more than to directly translate it makes more
sense here? In regards to fossils using something like _well preserved_ seems
to fit, e.g.

> The fossil was so well preserved, it looked as though the cave lion was
> merely sleeping.

Or something along those lines.
