High Quality Content by WIKIPEDIA articles! The taxonomy of cone shells and their allies as proposed by John K. Tucker and Manuel J. Tenorio in 2009 is a biological classification system for a large group of predatory sea snails. This system is currently (2011) the latest and most comprehensive attempt to make taxonomic sense of the large and diverse group which contains the cone snails. The treatise setting out this classification was published in 2009. The authors proposed extensive changes to the family Conidae, as compared with the way the group was treated in the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Bouchet and Rocroi had included in the family Conidae several other groups of toxoglossan snails which had previously been placed in the Turridae.
