Megasurcula wynoocheensis is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.[7] The name originates from the Wynoochee Valley of Washington state.[6]

Description

The length of the shell attains 43 mm, its diameter 21.4 mm.

This is a slender, high-spired turrid with a strongly concave whorl profile and sutures riding high upon the vertical segment of the preceding whorls.[6]

Distribution

Fossils of this marine species have been found in Miocene strata in the Pacific Ocean Northwest in the United States. The type locality was a logging road west of Montesano, Washington.[6] It has also been found in Oregon and California.[6]
