A taxonomic classification for a group of extinct cephalopod mollusks related to ammonites.
From ammonite + Latin -idae (taxonomic family suffix). The -idae suffix derives from Latin and is the standard way to name biological families in scientific nomenclature, established by Linnaeus.
The -idae and -id suffixes in biology allow scientists to organize life into nested groups like Russian dolls—anammonidae is a family containing multiple genera, showing how we organize 350 million years of evolutionary history.
