Some Aspects of the Brachiopod–Brachiopod Relationships

Paleontological Journal, 2018
The 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 ...

Peduncular attached secondary tiering acrotretoid brachiopods from the Chengjiang fauna: Implications for the ecological expansion of brachiopods during the Cambrian explosion

Palaeogeography, Palaeoclimatology, Palaeoecology, 2012
Brachiopods are usually thought to contribute little to the tiering complexity from the Paleozoic to the Recent, mainly due to the fact that their recent representatives live primarily in lower tiers directly above or below the water-sediment interface ...

Two sources of mesoderm in brachiopods

Доклады Российской академии наук. Науки о жизни, 2023
In 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.

Body volumes and internal space constraints in articulate brachiopods

Lethaia, 1992
Brachiopods were once dominant in all the oceans of the world. but their distributions are non more restricted. There are few species which are found in shallow warm habitats and these are predominantly small.
