Erato subcypraeola
Taxonomy
Erato subcypraeola was named by d'Orbigny (1852) [Erato subcypraeola ]. It is a 3D body fossil. Its type locality is Angers, which is in a Miocene marine horizon in France.
It was recombined as Erato (Eratopsis) subcypraeola by Cossmann and Peyrot (1923); it was recombined as Eratopsis subcypraeola by Lozouet et al. (2001); it was misspelled as Erato subcypreola by Zunino and Pavia (2009), Fehse and Grego (2012).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. Fehse and J. Grego 2012 | Shell is medium sized, relatively fragile, elongated pear-shaped, with an elevated, somewhat pointed spire. Protoconch mostly covered by callus, but visible in a few specimens. It consists of 1.5 to 2 inflated whorls and a minute nucleus. Protoconch rounded. Suture indistinct. Teleoconch consists of approximately 31/4 whorls. Spire covered by very thick callus, which covers the suture. Body whorl almost 90% of total height, shouldered adapically, with the maximum diameter at # of the distance from the adapical suture, evenly tapering below and only slightly constricted at the ventrum. Dorsum usually covered with minute to large pustules, concentrated mostly around the spire. Dorsum rounded. Dorsal sulcus incised but represented by at least a dimple behind the anterior extremity in fully adult specimens. Aperture comprises about 85% of total height, almost straight and narrow. Labrum broad, thickened, smooth, somewhat flattened and sloping slightly into the aperture, rounded at the outer margin, bearing 16 to 19 teeth of irregular strength, which extend onto the labrum for a variable distance. Siphonal canal short, indented, rounded and straight. Columella almost straight, with a weakly developed inner carinal ridge and a slightly thickened parietal lip. Columellar denticles vary from 15 to 17 in number. Anterior 3-5 denticles are developed as folds, running obliquely across the ventrum, the remaining ones weakly developed or obsolete. Fossula not delimited from the columella. Inner fossular margin slightly constricted. Terminal ridge simple.
Range of variation – The pustules on the shell surface vary in strength and number. Sometimes the whole shell is completely pustulated (Baluk, 1995, pl. 13, fig. 1) whereas other specimens are almost smooth (Baluk, 1995, pl. 13, fig. 2). The dorsal sulcus can be strongly developed or reduced to a dimple behind the anterior extremity. The anterior ventral folds vary slightly in number. The shell outline could vary from stout, almost ovate to somewhat elongated and pyriform. The labral denticles vary in strength, shape and spacing. |
