Conus sp.  (Ladd, 1970)

 

 

A single cone is small with a moderately high flat spire; the shoulder is rounded, the sides of body whorl flat; early whorls are scalloped at the suture, this feature less prominent on later whorls; anal fasciole concave; aperture narrow, widening slightly anteriorly; traces of low spirals are preserved anteriorly.

 

Measurements. USNM 650553; height 15 mm, diameter 7.7 mm; it is the largest gastropod in the extensive Eocene fauna.

 

Most cones are found in warm equatorial waters where they are particularly abundant on rocky reef flats and other shallow-water terraces. A few cones have been taken alive from depths of 30-40 fathoms, but the worn  condition of the Eocene fossil suggests that it was carried to its final resting place from shallow water.
