'amonites'不是一个国家的语言，而是一个英文单词，指的是一类已灭绝的海生无脊椎动物——菊石。它们生活在地球史上的中生代，约2.4亿年前至6600万年前，是古生代和新生代之间的一个重要过渡群体。由于其独特的外形和发育史，amonites在地质学和古生物学中有着重要的研究价值。
以下是9个含有amonites的例句：
1. Fossils of ammonites have been found all over the world.（菊石化石在全世界范围内都有发现。）
2. The study of ammonites can reveal a lot about ancient marine ecosystems.（研究菊石可以揭示很多关于古代海洋生态系统的信息。）
3. Ammonites evolved rapidly and diversified during the Mesozoic era.（菊石在中生代快速进化和多样化。）
4. The intricate patterns on ammonite shells are truly stunning.（菊石壳上复杂的图案真的很惊人。）
5. Some species of ammonites were able to reach sizes of up to two meters in diameter.（一些菊石物种能够达到直径两米的大小。）
6. The extinction of ammonites was likely caused by a combination of factors, including climate change and competition with other marine organisms.（菊石的灭绝可能是由多种因素造成的，包括气候变化和与其他海洋生物的竞争。）
7. Ammonites were a major food source for marine predators such as mosasaurs and sharks.（菊石是海洋掠食者如海蛇和鲨鱼的主要食物来源。）
8. The discovery of intact ammonite specimens is quite rare, as they are often crushed or broken during fossilization.（完整的菊石标本的发现相当罕见，因为它们在化石化过程中经常被压碎或折断。）
9. The study of ammonites has contributed greatly to our understanding of the evolution of marine life on Earth.（对菊石的研究对我们理解地球上海洋生物的演化做出了巨大贡献。）
