• The early embryological stages are reminiscent of ancestral gastropods and extant Monoplacophora.
• They might be snails ( Gastropoda ) or they might be Monoplacophora.
• The Paleozoic molluscs of uncertain position within Mollusca ( Gastropoda or Monoplacophora ).
• They have isostrophically coiled shells and may be either Gastropoda sea ( snail ) s, or Monoplacophora.
• In 2010, she led the cruise that recovered large numbers of Monoplacophora for molecular and phylogenomic analysis.
• Scientists believe that the taxon Monoplacophora is probably polyphyletic and have proposed including all the living members in the order Tryblidiida.

• Bouchet & Rocroi ( 2005 ) divide the Bellerophontoidea into 8 families listed Paleozoic molluscs with isostrophically coiled shells of uncertain position within Mollusca ( Gastropoda or Monoplacophora)
• In addition, an animal may be classified as " pseudometameric " meaning that it has clear internal metamerism but no corresponding external metamerism as is seen, for example, in Monoplacophora.
• "' Aldanellidae "'is an extinct family of paleozoic molluscs that have been assigned to the Gastropod stem group but may also belong to a paraphyletic " Monoplacophora ".
• "' Ladamarekiidae "'is an extinct family of Paleozoic fossil molluscs of uncertain position . it is not known if they are sea snails ( Gastropoda, or Monoplacophora ).
• The inner shell layers of " Fordilla " and " Pojetaia " species both consist of layers of carbonate, which is akin to the laminar aragonite layer found in extant monoplacophora.
• "' Monoplacophora "', meaning " bearing one plate ", is a polyphyletic Extant representatives were not recognized as such until 1952; previously they were known only from the fossil record.
• Bouchet & Rocroi ( 2005 ) points out ( page 271 ) that assignment of " " symmetrical univalved mollusks " bellerophonts " either to Gastropoda or to Monoplacophora or Tergomya is controversial . ""
• Bouchet & Rocroi, on page 271 ( 2005 ), also state that the assignation of " " symmetrical univalved mollusks " bellerophonts " either to Gastropoda or to Monoplacophora or Tergomya is controversial . ""
