Most Cambrian arthropods employed simple feeding mechanisms requiring only low degrees of appendage differentiation. In contrast, post-Cambrian crustaceans exhibit a wide diversity of feeding specializations and possess a vast ecological repertoire. Crustaceans are evident in the Cambrian fossil record, but have hitherto been known exclusively from small individuals with limited appendage differentiation. Here we describe a sophisticated feeding apparatus from an Early Cambrian arthropod that…

A suspension-feeding anomalocarid from the Early Cambrian

The observations demonstrate that large, nektonic suspension feeders first evolved during the Cambrian explosion, as part of an adaptive radiation of anomalocarids, and indicate the existence of a complex pelagic ecosystem supported by high primary productivity and nutrient flux.

New suspension-feeding radiodont suggests evolution of microplanktivory in Cambrian macronekton

Fossil evidence is provided that Pahvantia hastata was a suspension-feeder that likely captured much smaller plankton than any other known free-swimming animals of that time, suggesting a more direct involvement of nekton in the establishment of an oceanic pelagic-benthic coupling in the Cambrian.

Exceptionally preserved crustaceans from western Canada reveal a cryptic Cambrian radiation

Diverse crustacean appendages of Middle and Late Cambrian age from shallow-marine mudstones of the Deadwood Formation in western Canada provide the earliest evidence for crown-group branchiopods and total-group copepods and ostracods, extending the respective ranges of these clades back from the Devonian, Pennsylvanian, and Ordovician.

A Eucrustacean Metanauplius from the Lower Cambrian

A new species of early Cambrian arthropod reconstructed from exceptionally preserved mandibles and associated small carbonaceous fossils (SCFs)

Mandibulate arthropods (myriapods, hexapods and crustaceans) account for a major component of extant animal diversity but their origins remain unclear. Here, we re‐examine the record of exceptionally…

The relationships among animals, detritus and its associated micro‐organism decomposers, taking a functional approach is explored, to arrive at new insights by disentangling them from an adaptive point of view.

Molecular Timetrees Reveal a Cambrian Colonization of Land and a New Scenario for Ecdysozoan Evolution

Arthropod visual predators in the early pelagic ecosystem: evidence from the Burgess Shale and Chengjiang biotas

The case of Isoxys supports the idea that off-bottom animal interactions such as predation, associated with complex feeding strategies and behaviours (e.g. vertical migration and hunting) were established by the Early Cambrian and suggests that a prototype of a pelagic food chain had already started to build-up at least in the lower levels of the water column.

An epipodite-bearing crown-group crustacean from the Lower Cambrian

The limb morphology and other details of this new species are markedly similar to those of living cephalocarids, branchiopods and copepods and it is assigned to the Eucrustacea, thus representing the first undoubted crown-group crustacean from the early Cambrian.

This new fossil evidence supports the remote ancestry of crustaceans well before the Late Cambrian and shows, along with other fossil data, that a variety of body plans already coexisted among the primitive crustacean stock.

THE LOWER CAMBRIAN CRUSTACEAN PECTOCARIS FROM THE CHENGJIANG BIOTA, YUNNAN, CHINA

Pectocaris is the first arthropod with definite crustacean characteristics described from strata from below the Upper Cambrian and probably belongs to the branchiopod crustaceans.

The Upper Cambrian Rehbachiella and the phylogeny of Branchiopoda and Crustacea

This study on Rehbachiella supports the monophyly of the crown-group Crustacea and reveals that only the first maxilla was morphologically and functionally included into the crustacean head, while subsequent limbs were addted to the head in a stepwise manner and became modified separately within the different crustacea lineages, which is of great relevance when evaluating the relationships between these.

Crustacean biodiversity through the marine fossil record

Ostracodes were the first major group to radiate, attaining high diversity during the Ordovician Period with other members of the Paleozoic evolutionary fauna; rates of extinction and responses to mass extinctions were also similar to those of groups within the paleozoic fauna.

This paper examines the evolution of aquatic free-living arthropods, the occupants of one such adaptive zone, from the Cambrian to the present, and analyzes evolutionary patterns revealed, and tests the idea that, within an adaptive zones, the specialization of its occupants increases with their taxonomic diversity.

Functional mouthpart morphology of the squat lobster Munida sarsi, with comparison to other anomurans

The mouthparts of Munida sarsi Huus, 1935, including the labrum and paragnaths, are described using LM and SEM, with special attention to the setal composition and its function, finding that the mouthparts closest to the mouth have the least complex movements and functional scheme.

The Tetraconata concept: hexapod-crustacean relationships and the phylogeny of Crustacea

Arguments for homology of the mandible throughout mandibulate arthropods and for a monophyletic Mandibulata will be presented, as well as arguments supporting the taxon Tetraconata (i.e. Crustacea + Hexapoda).
