Deniz Yumuşakçası Altsınıfı
Genel bilgiler
Ammonoidler veya yaygın adıyla Ammonitler (Ammonoidea), soyu tükenmiş deniz yumuşakçalarından oluşan, kafadan bacaklılar sınıfına bağlı bir altsınıftır.
Bu yumuşakçaların günümüzde yaşayan en yakın akrabaları, görüntülerinin benzer olmasına karşın Notilus gibi canlıların dahil olduğu Nautiloid altsınıfındaki türler değil, coleoidea (ör. ahtapot, kalamar ve mürekkep balığı) altsınıfındaki türlerdir.
Bu yumuşakçalar ilk olarak Devoniyen döneminde ortaya çıkmış, yaşayan son tür ise Kretase-Tersiyer yok oluşuyla beraber yok olmuştur.
