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 frontal appendages, stalked, circular eyes, a simple, sub-triangular head shield, and a trunk with 15 tergites, the anterior nine each bearing a single medial axial spine. Limited evidence suggests biramous trunk appendages with paddle-shaped exopods. At the posterior end is a sub-triangular region…

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.

A soft‐bodied euarthropod from the early Cambrian Xiaoshiba Lagerstätte of China supports a new clade of basal artiopodans with dorsal ecdysial sutures

A new monophyletic clade, Protosutura nov., occupies a basal phylogenetic position within Artiopoda as sister‐group to Trilobitomorpha and Vicissicaudata, illuminates the ancestral organization of these successful euarthropods, and leads to a re‐evaluation of the evolution of ecdysial dorsal sutures within the group.

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.

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.

Fossils from South China redefine the ancestral euarthropod body plan

Sklerolibyon and other jianfengiids expand the disparity of megacheirans and suggest that the common euarthropod ancestor possessed a remarkable phenotypic variability associated with the externalized cephalon, as well as endopods that were already heptopodomerous, which differs from previous hypotheses and observations.

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.


The radial arrangement of the circum‐oral sclerites suggests that anomalocaridids were related to aschelminth worms rather than to arthropods.

Anatomy and lifestyle of Kunmingella (Arthropoda, Bradoriida) from the Chengjiang fossil Lagerstätte (lower Cambrian; Southwest China)

Although it resembles other Chengjiang euarthropods in important aspects of its body plan, Kunmingella possesses several features which support the view that bradoriids may be very early derivatives of the stem line Crustacea, and shows no major sign of limb specialization.

Soft Anatomy of the Early Cambrian Arthropod Isoxys curvirostratus from the Chengjiang Biota of South China with a Discussion on the Origination of Great Appendages

Morphological comparisons demonstrate that species of Isoxys were diverse in feeding habits and occupied a very broad morphospace, i.e., carapace bivalved or a single shield, the pre-oral limbs antenniform or modified into great appendages, the succeeding endopods slim or stout.
