'agelacrinites' originates from Greek, specifically the word 'agelakrinon,' where 'agela' meant 'herd' and 'krinon' meant 'lily.'

'agelakrinon' transformed into the Latin word 'agelacrinites,' and eventually became the modern English word 'agelacrinites' through scientific nomenclature.

Initially, it referred to a 'herd of lilies,' but over time it evolved into its current meaning of a genus of extinct crinoids.
