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.
