Hallucigenia’s onychophoran-like claws and the case for Tactopoda
The Palaeozoic form-taxon Lobopodia encompasses a diverse range of soft-bodied ‘legged worms’ known from exceptional fossil deposits. Although lobopodians occupy a deep phylogenetic position withinExpand

A superarmored lobopodian from the Cambrian of China and early disparity in the evolution of Onychophora
Significance Paleozoic lobopodians constitute a diverse assemblage of worm-like organisms that are known from various exceptional fossil deposits and were among the earliest animals to developExpand

Fuxianhuiid ventral nerve cord and early nervous system evolution in Panarthropoda
Significance Understanding the evolution of the CNS is fundamental for resolving the phylogenetic relationships within Panarthropoda (Euarthropoda, Tardigrada, Onychophora). The ground pattern of theExpand

Specialized appendages in fuxianhuiids and the head organization of early euarthropods
The organization of the head provides critical data for resolving the phylogenetic relationships and evolutionary history of extinct and extant euarthropods. The early Cambrian-period fuxianhuiidsExpand

Origin and evolution of the panarthropod head - A palaeobiological and developmental perspective.
The panarthropod head represents a complex body region that has evolved through the integration and functional specialization of the anterior appendage-bearing segments. Advances in the developmentalExpand

Burgess Shale-Type Microfossils from the Middle Cambrian Kaili Formation, Guizhou Province, China
Diverse carbonaceous microfossils, including exceptionally preserved remains of non-biomineralizing metazoans, are reported from a basal middle Cambrian interval of the Kaili Formation (GuizhouExpand

Homology of Head Sclerites in Burgess Shale Euarthropods
The Cambrian fossil record of euarthropods (extant arachnids, myriapods, crustaceans, hexapods) has played a major role in understanding the origins of these successful animals and indicates thatExpand

The phylogeny of aglaspidid arthropods and the internal relationships within Artiopoda
The phylogenetic position of aglaspidids, a problematic group of Lower Palaeozoic arthropods of undetermined affinities, is re‐examined in the context of the major Cambrian and OrdovicianExpand

Early Cambrian fuxianhuiids from China reveal origin of the gnathobasic protopodite in euarthropods
Euarthropods owe their evolutionary and ecological success to the morphological plasticity of their appendages. Although this variability is partly expressed in the specialization of the protopoditeExpand
