Abstract Nectocaridids are soft-bodied early to middle Cambrian organisms known from Burgess Shale-type deposits in Canada, China, and Australia. Originally described as unrelated species, they have recently been interpreted as a clade; their flexible tentacles, camera-type eyes, lateral fins, internal gills, axial cavity, and funnel point to a relationship with the cephalopods. However, aspects of this reinterpretation, including the relevance of the group to cephalopod evolution, have been… 

An Ordovician nectocaridid hints at an endocochleate origin of Cephalopoda

A new nectocaridid is document from the Whetstone Gulf Formation, extending the group's range into the Late Ordovician and indicating a trend towards increased metabolic efficiency through the course of Cambrian–Ordovician evolution.

A possible Cambrian stem-group gnathiferan-chaetognath from the Weeks Formation (Miaolingian) of Utah

D. thambus is interpreted as an ambush predator and may have been partially infaunal, but the wider affinities of this new taxon remain conjectural, but it is suggested that it may represent a stem-group member of the Gnathifera, today represented by the gnathostomulids, micrognathozoans and rotifers and possibly with links to the chaetognaths.

Ontogeny, morphology and taxonomy of the soft‐bodied Cambrian ‘mollusc’ Wiwaxia

It is demonstrated that Wiwaxia did not undergo discrete moult stages; rather, its scleritome developed gradually, with piecewise addition and replacement of individually secreted sclerites.

A phylogeny of fossil and living neocoleoid cephalopods

A morphological data matrix including both extinct and extant taxa is presented and a octopodiform interpretation for most fossil coleoids is suggested and the fossil sister taxon to the octopods is suggested to be Plesioteuthididae.

The Cambrian cirratuliform Iotuba denotes an early annelid radiation

The principal animal lineages (phyla) diverged in the Cambrian, but most diversity at lower taxonomic ranks arose more gradually over the subsequent 500 Myr. Annelid worms seem to exemplify this

Early cephalopod evolution clarified through Bayesian phylogenetic inference

It is proposed that using a posteriori pruned maximum clade credibility trees help in assessing support for phylogenetic relationships among a set of relevant taxa, because they provide clade support values that better reflect the phylogenetic signal.

The origins of molluscs

Aplacophoran morphology therefore does not represent the plesiomorphic condition for molluscs as a whole, and the interrelationships among the conchiferan mollsuscs are still a matter of contention and require further palaeontological and molecular phylogenetic scrutiny.

In the aggregate, modern data from molecular biology, palaeontology, and comparative embryology/morphology, having been revitalized by the introduction of new microscopy techniques, imply that the hypothesized planktotrophic gastrae-like common ancestor is the least likely of the diverse suggestions on the origins of the Metazoa.

Hallucigenia’s head and the pharyngeal armature of early ecdysozoans

Phylogenetic results indicate that equivalent structures characterized the ancestral panarthropod and, seemingly, the ancestral ecdysozoan, demonstrating the deep homology of panaranthropod and cycloneuralian mouthparts, and providing an anatomical synapomorphy for the ecdy sozoan supergroup.

Primitive soft-bodied cephalopods from the Cambrian

This work reinterpretes the problematic Middle Cambrian animal Nectocaris pteryx as a primitive (that is, stem-group), non-mineralized cephalopod, based on new material from the Burgess Shale, and indicates that primitive cepinghalopods lacked a mineralized shell, were hyperbenthic, and were presumably carnivorous.

The morphology, mode of life, and affinities of Canadaspis perfecta (Crustacea: Phyllocarida), Middle Cambrian, Burgess Shale, British Columbia

The evidence suggests that C. perfecta fed on coarse particles, possibly with the aid of currents set up by the biramous appendages, as the earliest well-preserved crustacean.

An Early Cambrian problematic fossil: Vetustovermis and its possible affinities

All the characters displayed in this 525 million-year old soft-bodied animal fail to demonstrate clear affinity with molluscs or any other known extant or extinct animal groups, but argue for representing an independently evolved animal group, which flourished in Early Cambrian and possibly in Middle Cambrian time.

Evidence for gill slits and a pharynx in Cambrian vetulicolians: implications for the early evolution of deuterostomes

Evidence is argued that evidence points towards vetulicolians being members of the stem-group deuterostomes; a group best known as the chordates but also including the ambulacrarians (echinoderms, hemichordates), and xenoturbellids.

The bearing of the new Late Cambrian monoplacophoran genus Knightoconus upon the origin of the Cephalopoda

Hypothetical reconstructions of molluscan anatomy support the notion that cephalopods may have been derived directly from a hypseloconid having a high, slightly curved, multiseptate, bilaterally symmetrical shell, by the subsequent development of a siphuncle.

Musculature of Angarella in some aspects resembles that of the Early Cambrian mobergellans with phosphatic shells, but in the calcitic shell structure it is similar to the craniopsid brachiopods.

The evolution of coleoid cephalopods and their present biodiversity and ecology

The roles that transitions between pelagic and benthic habitats played in the evolution of cephalopods are noted, and the possibility is advanced that the most recent "oceanic anoxic event" may have established a time marker for the divergence of some oegopsid families.

A growing body of evidence from the fossil record, embryology and Bayesian molecular divergence estimations provides a comprehensive picture of cephalopods' origins and evolution.

Middle Cambrian ctenophores from the Stephen Formation, British Columbia, Canada

The Ctenophora are a marine phylum of gelatinous swimmers and crawlers, with a minimal fossilization potential, but they probably evolved very early in the metazoan radiations, perhaps from an animal with an anterio-posterior axis and a ciliated surface.
