摘要
菊石是一类生存了将近3亿年、业已绝灭的海洋动物;它们的化石在地层学和古生物学具有极大的科学价值。此外,由于菊石壳形多变、壳层美丽,标本容易保存完整,在远古时期就有许多关于菊石的神奇传说,这类动物化石之所以取名为Ammonites,也是源于其中。
Ammonites are one of extinct marine faunas at subphy- lum level, living for a length about 30（I million-years; they have high scientific values in stratigraphy and paleontology. Moreover, ammonite fossils have contributed to mythology and palce names to a surprising high degree, due to their beautiful shell, varied forms, and well-preserved samples. There were popular legends about ammonites many years ago.
