Conus caleocius (Vokes, 1939)

 

 


This species is characterized by the presence of strong spiral ribs over the entire body whorl, 13 to 14 nodes on the shoulder of the body whorl, and a row of small nodes immediately anterior to the suture. 

 

Stage range: "Capay Stage"; "Domengine Stage"

 

Conus caleocius (4)

 

Preservation is fair. Although the best preserved specimen 
(Fig. 41) is incomplete, it shows the diagnostic strong spiral 
ribs over the entire body whorl, noded body-whorl shoulder, 
and a row of small nodes immediately anterior to the suture. 
Previously, this distinctive species had not been reported 
as ranging stratigraphically into the “Capay Stage.”
