""'Ecphora " "'is a genus of extinct predatory ocenebrinid murexes indigenous to the North American Eastern Seaboard from Miocene until their extinction during the Pliocene.

Eventually, by the end of the early Pliocene, " Ecphora " and " Planecphora " were restricted to the Everglades atoll, until their extinction due to competition by newer murex genera invading from the Caribbean.

These genera persisted until their extinction during the early Pliocene . " Ecphora " also persisted, though, its species were slowly pushed south to coral reefs in southern Florida due to climate changes turning the Eastern Seaboard from tropical / subtropical to temperate.
14.
The three-ribbed " Trisecphora " would then give rise to the ( mostly ) four-ribbed genus " Ecphora ", and both genera coexisted together with " Chesathais " and " Ecphorosycon ", along with " Ecphora "'s subgenus " Planecphora ", up until midway through the Serravallian stage, when " Planecphora " was extirpated from the Eastern American Seaboard ( surviving only in coral reefs of Florida ), and all ecphora genera up to this time, save for " Ecphora ", itself, became extinct.
