Fallax Dalliniformis
''Fallax'' is a genus of brachiopods belonging to the family Aulacothyropsidae. The first species of this genus described (''F. dalliniformis'') occurs in the north-eastern Atlantic. Other members of the genus are recorded from Antarctica (''F. antarcticus'') and New Caledonia (''F. neocaledonensis''). ''Fallax'' is diagnosed by having shells that are oval to subpentagonal in shape, with the anterior commissure (line where the valves meet anteriorly) straight or folded (parasulcate). The shell has an erect beak, and conjunct deltidial plates, the foramen being of a 'permesothyrid' type. The hinge teeth are supported by dental plates, and the lophophore support (branchidium) is of a 'dipoloform' type. ''Fallax'' species have superficial similarity to some members of Dallinidae, but can be distinguished by the persistence of dental plates.

Brachiopods
Brachiopods (), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major categories are traditionally recognized, articulate and inarticulate brachiopods. The word "articulate" is used to describe the tooth-and-groove structures of the valve-hinge which is present in the articulate group, and absent from the inarticulate group. This is the leading diagnostic skeletal feature, by which the two main groups can be readily distinguished as fossils. Articulate brachiopods have toothed hinges and simple, vertically-oriented opening and closing muscles. Conversely, inarticulate brachiopods have weak, untoothed hinges and a more complex system of vertical and oblique (diagonal) muscles used to keep the two valves aligned. In many brachiopods, a s ...

Aulacothyropsidae
Aulacothyropsidae is a family of brachiopods belonging to the order Terebratulida Terebratulids are one of only three living orders of articulate brachiopods, the others being the Rhynchonellida and the Thecideida. Craniida and Lingulida include living brachiopods, but are inarticulates. The name, Terebratula, may be derived f ....

Lophophore
The lophophore () is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Hyolitha, and Phoronida, which collectively constitute the protostome group Lophophorata.Introduction to the Lophotrochozoa – Retrieved 3 May 2010 All lophophores are found in aquatic organisms. Etymology ''Lophophore'' is derived from the Greek ''lophos'' (crest, tuft) and ''-phore'', ''-phoros'' (φορος) (bearing), a derivative of ''phérein'' (φέρειν) (to bear); thus crest-bearing.Characteristics The lophophore can most easily be described as a ring of ted tentacles surrounding the mouth, but it is often horseshoe-shape ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Fallax'' is a genus of brachiopods belonging to the family Aulacothyropsidae. The first species of this genus described (''F. dalliniformis'') occurs in the north-eastern Atlantic. Other members of the genus are recorded from Antarctica (''F. antarcticus'') and New Caledonia (''F. neocaledonensis''). ''Fallax'' is diagnosed by having shells that are oval to subpentagonal in shape, with the anterior commissure (line where the valves meet anteriorly) straight or folded (parasulcate). The shell has an erect beak, and conjunct deltidial plates, the foramen being of a 'permesothyrid' type.
