通称：菊石
物种：菊石目
时代：侏罗纪末期——白垩纪中期
食性：食底泥
性情：被动型
野生
通常能在岛屿周边水域的最深处找到菊石这种生物，它与其他深海生物之间有着一种奇妙的关系。因为几乎所有邻近的海洋生物都会在菊石遭受攻击时上前保护，所以菊石肯定是对这些生物有利。 但是这种不寻常的共生关系究竟根基在哪，目前我还没有找到这个答案。 菊石也能在更深的水下洞穴当中被发现。不过即便是在这样的洞穴中，在对其进行攻击时也能吸引周边生物的注意，所以捕获这种富含丰富资源的壳体生物可能不是个好主意，其周围就可能就潜藏着某种危险。
家养
就像其他诸多不可被驯化的海底生物一样，菊石拥有极高的价值，成为部族的猎获目标。如果有部族胆敢冒着风险激怒周围的保护者来猎杀菊石，那么就能从其尸体的内脏中取得菊石胆汁。 这种胆汁可以用于与其他化学物质相混合来做成一种功能强大的调和物，最有名的一种调和物可以让生物暴怒并攻击气味的源头。
Common name: Ammonite
Species: Ammonitina multiamicus
Time: Late Jurassic-Mid Cretaceous
Diet: Feeder
Temperament: Passive
Wild
Usually found in the deepest parts of the waters around the Island, Ammonitina multiamicus has a strange relationship with the other creatures of the deep. It must do something beneficial for them since every nearby sea creature defends Ammonitina when it is attacked. What this distinct symbiosis is based on, alas, I have not yet discovered. Ammonitina has also made its way into the deeper parts of many underwater caves. Even within these caves, the creature will draw attention if assaulted, making harvesting its resource-rich shell a tricky proposition, depending on what other dangers may be lurking nearby.
Domesticated
Like many of the untameable ocean dwellers, Ammonitina still has enough utility to be a valuable hunting target. If a tribe is willing to risk the wrath of nearby would-be protectors, Ammonitina bile can be harvested from the innards of its corpse. This bile can then be worked over with other chemicals to produce powerful concoctions, the most notable being a mixture that causes creatures to become enraged and attack the source of the scent.
