Megasurcula howei is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.

This high-spired, biconic species differs from Megasurcula condonana (Anderson and Martin, 1914) by having a smoothly conic spire and relatively narrower body whorl.

When the body whorl angulation is used as a point of reference, in non-apertural view, the upper cone of M. howei is relatively higher than the lower cone, whereas the reverse is true in specimens of the stout-shelled M. condonana.

It is closely related to † Megasurcula guayasensis of the Miocene in Ecuador, but differs by being less slender, a bit taller and less finely noded.

[2] Fossils of this marine species have been found in Miocene strata of the Temblor Formation, California.
