BackgroundEarly Cambrian Lagerstätten from China have greatly enriched our perspective on the early evolution of animals, particularly arthropods. However, recent studies have shown that many of these early fossil arthropods were more derived than previously thought, casting uncertainty on the ancestral euarthropod body plan. In addition, evidence from fossilized neural tissues conflicts with external morphology, in particular regarding the homology of the frontalmost appendage.ResultsHere we… 

An early Cambrian euarthropod with radiodont-like raptorial appendages

The phylogenetic reconstruction recovers Kylinxia as a transitional taxon that bridges Radiodonta and Deuteropoda, providing insights into the phylogenetic relationships among early euarthropods, the evolutionary transformations and disparity of frontalmost appendages, and the origin of crucial evolutionary innovations in this clade.

New multipodomerous appendages of stem-group euarthropods from the Cambrian (Stage 4) Guanshan Konservat-Lagerstätte

Two new euarthropods from the Cambrian Stage 4 Guanshan Biota of South China are reported, with Lihuacaris ferox appendages resembling the frontal appendages of radiodonts, as well as the post-oral endopods of chengjiangocaridid fuxianhuids and other deuteropods with well-documented raptorial/predatory habits.

The problematic Cambrian arthropod Tuzoia and the origin of mandibulates revisited

The origin of mandibulates, the hyperdiverse arthropod group that includes pancrustaceans and myriapods, dates back to the Cambrian. Bivalved arthropod groups such as hymenocarines have been argued

A new euarthropod with large frontal appendages from the early Cambrian Chengjiang biota

We describe Fengzhengia mamingae gen. et sp. nov., a new euarthropod from the lower Cambrian (Series 2, Stage 3) Chengjiang Lagerstätte, Southwest China. Fengzhengia mamingae possesses prominent

Ordovician opabiniid-like animals and the role of the proboscis in euarthropod head evolution

Phylogenetic analysis suggests that two specimens of opabiniid-like euarthropods with anterior proboscis from the Middle Ordovician Castle Bank Biota, Wales, UK may be sister to radiodonts and deuteropods, substantially extending the geographic and temporal range of Opabiniidae.

Fuxianhuiids are mandibulates and share affinities with total-group Myriapoda

In spite of their unrivalled ecological success, the origins of terrestrial mandibulates have long remained virtually unknown. In recent years, claims have been made based on phylogenetic results

A Burgess Shale mandibulate arthropod with a pygidium: a case of convergent evolution

Cambrian bivalved arthropods are a polyphyletic group of carapace‐bearing arthropods that includes stem euarthropods, stem mandibulates and crustaceans. Here, we describe Pakucaris apatis gen. et sp.

A new euarthropod with ‘great appendage’-like frontal head limbs from the Chengjiang Lagerstätte, Southwest China

Although, due to the absence of critical soft anatomy, the authors cannot elucidate the exact segmental affinities of these raptorial appendages, the possession of ‘great appendage’-like frontal head limbs is important for assessing the range of limb morphology evolved by early euarthropods.

Exceptional multifunctionality in the feeding apparatus of a mid-Cambrian radiodont

Stanleycaris and similar hurdiids provide an extreme example of the evolution of division of labor within the appendage of a stem euarthropod and suggest that this innovation may have facilitated the functional transition, from raptorial to sweep feeding, at the origin of the hurdiid clade.



Burgess Shale fossils illustrate the origin of the mandibulate body plan

The presence of crustaceomorph traits in the Cambrian larvae of various clades basal to Mandibulata is reinterpreted as evidence for the existence of distinct ontogenetic niches among stem arthropods and Hymenocarines now illustrate that the subdivision of the basipod and the presence of proximal endites are likely to have been ancestral conditions critical for the evolution of coxal and pre-coxal features in mandibulates.

A large new leanchoiliid from the Burgess Shale and the influence of inapplicable states on stem arthropod phylogeny

A new leanchoiliid is described, Yawunik kootenayi gen. nov, based on 42 specimens from the newly discovered Marble Canyon locality of the Burgess Shale, which stresses the historical importance of polarization over data content in scenarios of early arthropod evolution and a pressing need to investigate the impacts of coding inapplicables, especially given the inflating effect of implied weights.

Burgess Shale fossils shed light on the agnostid problem

Soft tissues from mature individuals of the agnostinids Peronopsis and Ptychagnostus from the middle Cambrian Burgess Shale are described, implying that crustacean-like morphologies evolved homoplastically.

A middle Cambrian arthropod with chelicerae and proto-book gills

Fossil material from the middle Cambrian Burgess Shale is used to show that Mollisonia plenovenatrix possessed robust but short chelicerae that were placed very anteriorly, between the eyes, which suggests that chelicers evolved a specialized feeding function early on, possibly as a modification of short antennules.

A Rare Onychophoran-Like Lobopodian from the Lower Cambrian Chengjiang Lagerstätte, Southwestern China, and its Phylogenetic Implications

Antennacanthopodia gracilis new genus and species is described and interpreted here as an “unarmoured” lobopodian from the Chengjiang fossil Lagerstätte (Early Cambrian, ∼520 Ma), Yunnan, southwestern China, furthers the understanding of early lobopODian diversification.

Multi-Segmented Arthropods from the Middle Cambrian of British Columbia (Canada)

The resultant topology indicates that analyses that have resolved megacheirans as stem-chelicerates have done so because they have rooted on inappropriate taxa, e.g., trilobitomorphs and marrellomorphs.

Cephalic and Limb Anatomy of a New Isoxyid from the Burgess Shale and the Role of “Stem Bivalved Arthropods” in the Disparity of the Frontalmost Appendage

The diversity of frontalmost appendages in “stem bivalved” arthropods, distinct in its absence of clear clustering, is found to link the morphologies of “short great appendages,” chelicerae and antennules, and fits the hypothesis of an increase in disparity of the deutocerebral appendage prior to its diversification in euarthropods.
