The problem was that while they were well documented at some sites, usually the ones with the very nice animals, there was also a large number of them where it was very vague -- there wasn't a lot of description or detail.
問題がありました 見事な動物と一緒に描かれているものは 割としっかり記録されていたのですが ぼんやりとしか描かれていないものが かなりの数に上り 記述も詳細も多くはありませんでした
