Hanleya is a genus of polyplacophoran molluscs known from Oligocene and Miocene fossils; [1] it is represented today by a number of species including H. sinica Xu 1990 (China), [2] [3] H. brachyplax (Brazil) [4] [5] and H. hanleyi Bean in Thorpe, 1844 (Chile), which feeds on sponges. [6]
Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
Monoplacophora, meaning "bearing one plate", is a polyphyletic superclass of molluscs with a cap-like shell now living at the bottom of the deep sea. Extant representatives were not recognized as such until 1952; previously they were known only from the fossil record, and were thought to have become extinct over 380 million years ago.
Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.
Lepidopleurus is an extant genus of chitons in the family Leptochitonidae.
Notoplax is a genus of chitons in the family Acanthochitonidae.
Ferussaciidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Achatinoidea.
Strophocheilidae is a taxonomic family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Acavoidea.
The Paleoloricata are valved polyplacophora without sutural laminae or insertion plates. The "order" probably represents a paraphyletic grouping.
Acutichiton is among the most primitive genera of Neoloricate chitons. Acutichiton became extinct during the Carboniferous period. Articulated specimens are known.
Glyptochiton is an extinct genus of polyplacophoran mollusc. Glyptochiton became extinct during the Carboniferous period.
Placiphorella, the veiled chiton, is a genus of polyplacophoran molluscs with precephalic tentacles, which are used in feeding.
Tryblidiida is a taxon of monoplacophoran molluscans containing the only extant representatives: 37 species are still alive today, inhabiting the ocean at depths of between 175 and 6,400 metres.
The Heloplacidae are a group of plated aplacophora known from Silurian deposits. Their best understood representative, Acaenoplax, can be taken as representative of the family; it is the only genus for which soft part anatomy is known.
Brasilennea is a fossil genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae. The genus is known only from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro. The most characteristic feature of the genus is its two spiral furrows on the body whorl.
Eoborus is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Strophocheilidae. Eoborus is the oldest fossil record of Strophocheilidae, dating from the Middle Paleocene of Brazil and Uruguay. The Brazilian species, alongside Eoborus charruanus from Uruguay, are the oldest fossil record of the family.
Eoborus rotundus is a fossil species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Strophocheilidae, from the Paleocene Itaboraí Basin, Brazil. Eoborus rotundus is a small species for the genus Eoborus, and the shell has a more rounded shape than average for the genus, a feature reflected in its species name.
Plagiodontes dentatus is a recent species of small to medium-sized air-breathing land snail, terrestrial pulmonate gastropods in the family Orthalicidae, subfamily Odontostominae. It occurs in Entre Ríos Province, Argentina.
Hanleya brachyplax is a species of chiton, a polyplacophoran mollusc, which is endemic to Brazil.
Itaborahia is a fossil genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Bulimulidae. The genus is known only from the Brazilian Paleocene deposits of the Itaboraí Basin, in the state of Rio de Janeiro.
