Trisecphora is a genus of extinct predatory ocenebrinid murexes indigenous to the Miocene coastline of what is now Maryland, North Carolina, and Virginia from the Aquitanian epoch until their extinction near the end of the Serravallian epoch. The common name for this genus and their relatives is "ecphora"(s).
The name "Ecphora" is Greek, meaning "bearing out." The word was originally used by Vitruvius to signify the projecture of a member or moulding of a column, and here refers to the distinctive "T-shaped" ribs that project from the shell.[1] The prefix "tris" is added to denote how all members of the genus have three ribs.
Subdivisions
As originally proposed by Petuch in 1988, Trisecphora was presented as a precursor subgenus of Ecphora (sensu stricto), even though a subgenus can not technically precede the genus that contains it. Later, Petuch would promote Trisecphora to the status of full genus.
