Orthogastropoda
Encyclopedia
Orthogastropoda was a major taxonomic groupings of snails and slugs, an extremely large subclass
within the huge class Gastropoda
according to the older taxonomy of the Gastropoda (Ponder & Lindberg, 1997)
.
This taxon is no longer used according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005
.
Ponder
and Lindberg
(1997) in the book The Southern Synthesis, showed the Orthogastropoda as one of two subclasses of the Gastropoda
, the other subclass being a very much smaller group called the Eogastropoda
, which contained only 5 families of true limpets.
This subclass, Orthogastropoda, which one perhaps could call the true snails, was defined most concisely as all gastropods which were not members of Patellogastropoda
, the true limpets.
The Orthogastropoda appeared to form a clade
which was supported by unambiguous synapomorphies. These synapomorphies (a series of characteristics that appear in its members but not in the other forms it diverged from) were the identifying characteristics of the clade.
Some of the characteristics were:
