Gastropoda - Triviidae

Taxonomy
Erato elongata was named by Seguenza (1880) [Neotype designated by Fehse & Landau 2002.]. Its type specimen is CS 5109, a shell, and it is a 3D body fossil.

It was recombined as Erato (Erato) elongata by Schilder (1933), Glibert (1963).

Diagnosis
ReferenceDiagnosis
D. Fehse and B. Landau 2001Shell medium sized, relatively solid, elongated pyrifonn with an elevated, somewhat pointed spire. Protoconch mostly covered by callus, but visible in numerous specimens; consisting of 2 Y2-2% whorls, with a small nucleus. The first protoconch whorl is tightly coiled and depressed, the second is convex, elevated and expands rapidly. Suture clearly marked and incised. Junction with teleoconch not clearly defined. Teleoconch consists of about 2 Y2 straight-sided whorls. The first teleoconch whorl is shorter than the preceding protoconch whorl. Spire covered by very thin callus, which partly obscures the suture. Body whorl 80o/o of total height, shouldered adapically, with the maximum diameter 1/4 distance from the adapical suture, evenly tapered below and only slightly constricted at the base. Dorsum smooth, rounded, without any dorsal sulcus. The shell surface is covered by a very thin callus, which is only partially preserved in most specimens. Aperture comprising about 75°/o of total height, straight and narrow. Outer lip thickened, smooth, with the outer margin evenly rounded, bearing 14-19 weak to very weak denticles, which are subobsolete in fully-grown specimens and do not extend onto the lip. Siphonal canal elongated, rounded and straight to recurved. Columella almost straight, with the carina) ridge developed only weakly in the fossular area. Columellar denticles present only in juvenile specimens. One or two short folds of variable strength are present on the base. Fossula indistinct, limited to a weak concave depression and poorly delimited from the columella. The inner border of the fossular area is weakly convex, extending into the aperture. Terminal ridge simple, short and weakly developed.
