Some Aspects of the Brachiopod–Brachiopod Relationships
Paleontological Journal, 2018The brachiopod–brachiopod relationships are analyzed for the first time based on the original material and literary data. The oppression of brachiopods by each other in the dense settlement is considered as amensalism. The only type of brachiopod relationships that may be considered as parasitism are brachiopod settlements within each other’s shells ...

Two sources of mesoderm in brachiopods
Доклады Российской академии наук. Науки о жизни, 2023In Bilateria, the formation of the coelomic mesoderm occurs in various ways and is of great significance for comparative embryology and phylogeny. Several early ontogenetic stages were studied in the brachiopod Coptothyris grayi by scanning electron microscopy and cytochemistry combined with confocal laser microscopy.

For some years past, the serious attention of several eminent malacologists has been directed to the endeavour to determine the affinities of the Brachiopoda, or the exact position the group should occupy in the animal kingdom. The Invertebrata have been grouped into five sub-kingdoms, namely, the Frotozoa, Cœlenterata, Annuloida, Annulosa, and ...

Brachiopoda occur scattered throughout the Belemnite Marls, but are abundant only at two horizons, namely in Beds 111–112, where several species of Cincta form a well-marked band; and in Beds 118–119, where crushed specimens of Tropiorhynchia thalia (A. d'Orbigny) are predominant.

Publisher Summary This chapter describes the biology of living brachiopods. The Brachiopoda are significant components of the early Cambrian marine Faunas and are therefore one of the few phyla to be represented of the Phanerozoic era, which extends from the first widespread appearance of organisms with mineralized skeletons until modern times.

Ecology of Articulated Brachiopods
The Paleontological Society Papers, 2001Ecology is the study of the relationships between organisms and their environments. For brachiopods living in marine habitats the main external factors of interest are temperature, water chemistry, light characteristics, and oxygen availability. However, organisms also modify their environments and in many cases the biotic environment may dictate ...

Mantle canals on brachiopod interareas and their significance in brachiopod classification
Lethaia, 1994Wright, A.D. 1994 10 15: Mantle canals on brachiopod interareas and their significance in brachiopod classification. Mantle canals have been located on the internal surface of the interareas in several clitambonitacean brachiopod genera. This indicates that, in contrast to the cardinal areas of Recent terebratulides and rhynchonellides, these ...

To be able to arrange, in the Geological Department of the British Museum (Natural History), the species known as Terebratula diphya and T. diphyoides , with their allies, it was necessary to ascertain the generic and specific names which such shells should bear.

Notes for a Short Course: Studies in Geology, 1981
Brachiopods are characterized by being solitary, bivalved, bilaterally symmetrical coelomates. A ciliated, filament-bearing lophophore occupies much of the mantle cavity of all living representatives and functions as the principal food-gathering and respiratory organ of the animal. The coelom is divided into two principal spaces. The largest one is the
