Brachiopods first appeared at the very beginning of the Phanerozoic together with the first skeletal organisms. Most brachiopod taxa that arose in the first half of the Cambrian had a short temporal range and became completely extinct by the middle of the Middle Cambrian. Rigid articulation of the valves of brachiopods was provided by various structures, which also appeared in the Early Cambrian. This fact points to the importance of this feature for the formation of the whole group and at the… 

The dawn of a dynasty : life strategies of Cambrian and Ordovician brachiopods.

Brachiopods are among the first animal phyla to emerge from the Cambrian Explosion, rapidly diversifying to all major palaeocontinental blocks within 20 million years. The group underwent another

Molecular paleobiological insights into the origin of the Brachiopoda

Congruence of the traditional molecular phylogenetic analysis, microRNAs, and morphological cladograms suggest that Brachiopoda is monophyletic with Phoronida as its likely sister group.

Brachiopods: origin and early history

The acquisition of new, and the redescription of existing faunas, in precise spatial and temporal frameworks, using new and well-established analytical and investigative techniques, are as important as ever.


Despite many major advances in recent years, three key challenges remain in bringing clarity to the early history of the phylum: (1) identifying the origin, morphology and life modes of the first

Divaricate patterns in Cambro-Ordovician obolid brachiopods from Gondwana

Abstract A new brachiopod species, Westonia mardini, from the Furongian of Turkey and a new occurrence of Westonia urbiona from the Cambrian Series 3 of Iberian Peninsula are reported. These new

The oldest Cambrian trilobite – brachiopod association in South China

Early Cambrian “Soft-Shelled” Brachiopods as Possible Stem-Group Phoronids

A new “soft-shelled” brachiopod from the Early Cambrian Mural Formation of western Alberta which provides a plausible candidate for a phoronid stem-group within (paraphyletic) Brachiopoda.

The architecture of Recent brachiopod shells: diversity of biocrystal and biopolymer assemblages in rhynchonellide, terebratulide, thecideide and craniide shells

Biological hard tissues are a rich source of design concepts for the generation of advanced materials. They represent the most important library of information on the evolution of life and its



A Supra-Ordinal Classification of the Brachiopoda

A new classification of the Brachiopoda is proposed to take into account recent advances in understanding of the anatomy, shell morphology, ontogeny and phylogeny of the phylum, and is divided into three subphyla, each typified by Recent species with early Palaeozoic ancestors and defined by easily identifiable synapomorphies.

Phylogenetic analysis of higher taxa of Brachiopoda

Inferred phylogenetic relationships within the Brachiopoda have long been accepted as demonstrating repeated transitions from a phosphatic shell chemistry to a calcareous composition. This

The ciliary feeding mechanism of the Megathyridae (Brachiopoda), and the growth stages of the lophophore

An examination of the method of feeding of the Megathyridae was considered desirable, and was made possible in the first instance through the kindness of M. Paul Bourgis, then, in 1955, on the staff of the Laboratoire Arago, Banyuls-surMer.

Inarticulate brachiopods from the Late Ordovician of New South Wales, and their palaeoecological significance

Late Ordovician formations in central-western New South Wales yield lingulide and acrotretide inarticulate brachiopods occurring in lithologies and faunal assemblages indicative of deeper-water

The oldest sequence of skeletal fossils in the Lower Cambrian of southeastern Newfoundland

Sections on the Burin Peninsula in southeastern Newfoundland show a record of continuous sedimentation during the Late Precambrian–Early Cambrian transition. These may be correlated lithologically


An Elliptocephala asaphoides fauna from rocks of the “Taconic sequence” of eastern New York is a characteristic “Schodack” faunule comparable in age and composition to those described by Ford from

Early Cambrian continental reconstructions

Climatically-related sedimentary facies and faunal distributions have been combined with palaeomagnetic data to make provisional reconstructions of the early Cambrian world. Laurentia, Baltica and

The ecology of Lower Cambrian buildups from Zuune Arts, Mongolia: implications for early metazoan reef evolution

Reefal buildups in western Mongolia of mid-Early Cambrian (late Atdabanian) age flourished during a period when shelf seas were globally widespread. The succession at Zuune Arts records the

Burrowing of the lingulid brachiopod Glottidia pyramidata: its ecologic and paleoecologic significance

X-radiography shows that the burrows of Glottidia are U-shaped: in a few hours, the animal reappears in feeding position with the anterior end pointing out of the sediment and the pedicle extending down into the burrow, explaining the substrate preferences of lingulids.
