Mangelia limata is an extinct species of sea snail, a marine gastropod in the family Mangeliidae. This species is known from a single fossil found in the Pliocene strata of Costa Rica. [1]
The shell of Mangelia limata is 9 mm long and 3.5 mm in diameter. It has a smooth, porcellaneous surface with a slightly shorter spire compared to the narrow aperture. The protoconch consists of three smooth, convex whorls followed by a half whorl that is finely ribbed. The three and a half subsequent whorls feature narrow, slightly oblique ribs, which cross the spire-whorls between the sutures. On the body whorl, eight ribs extend down to the anterior canal. The areas between the ribs are wide, flat, and smooth. Fine, subobsolete spiral lines are faintly etched on the tops and sides of the ribs. The aperture is linear-elliptical, and the outer lip is thickened by the last rib and smooth on the interior. The anterior canal is long and straight. [1]
The fossil of Mangelia limata was discovered in the Gatun Stage of Pliocene-aged strata in Costa Rica, providing insight into the marine life of that region during the Pliocene epoch.
